Pulse power supply gold plating

Pulse power supply gold plating

Pulse power supply gold plating superiority:

The superiority of pulse power supply plating can be better reflected especially on gold plating. Pulse power supply gold plating could obtain dense crystal electroplating layer coating, that not only significantly increased its finish degree, corrosion resistance, weldability, wear resistance, high temperature capability and have a greater degree of discoloration, but also greatly saved gold.

Pulse power supply gold plating

Pulse power supply gold plating

Someone think no need pulse power supply gold plating:

But there is a view: that barrel gold electro plating using pulse power supply of little significance to improve the density, which their reason is that the barrel plating machine tumbling action make the coarse crystals can not grow, therefore can get dense electroplating layer coating, bright, so no need use a pulse power supply. This view seems not unreasonable, but that is biased. Because barrel plating machine tumbling just a mechanical polishing action, its limited capacity and can not replace the role of fine-grained action generated large pulse current by electro chemical polarization. Therefore, if there is high quality requirements of gold plating, still need to use pulse rectifier gold plating, which this is the best control method outside the plating tank.

Vivid explain to tell you why need pulse power supply gold plating:

For example, now integrated lead frame, linear tube shell, connectors and other parts the pulse power supply barrel plating has been very common.
Also, there is gradually formed a consensus that gold plating bottom plating – nickel layer electroplating should also adopts pulse rectifier plating. The reason is pulse-plated nickel layer of stress, density, uniformity is far superior to the DC rectifier nickel plating, which undoubtedly will lay a solid foundation for gold electro plating, thus greatly improving the functional indicators of gold plating.
For example, one electronic products factory choosing pulse rectifier plating for products gold plating, and the thickness of the gold electro plating layer meet the requirements, which plating workpieces appearance is also good, but still can not meet the 380 ℃ ~ 450 ℃ temperature assessment test. Then they hire experts to help them to solve the problem. One of the measures is to use a pulse power supply nickel barrel plating instead of DC power supply, of course, there are other measures, such as strict operation, improved Pulse power supply gold plating liquid formulations and so on.

The parameters pulse power supply gold plating adopt can refer to the following:

Single pulse: 10% to 20% duty cycle (turn on: 0.1ms ~ 0.2ms, turn off: 0.8ms ~ 0.9ms), pulse frequency 900Hz ~ 1000Hz, the average current density equal to or slightly larger than the DC power source plating;
Reverse pulse: positive pulse duty cycle of 20% (turn on: 0.2ms, turn off: 0.8ms), working time 100ms, the average current density equal to or slightly larger than the DC rectifier plating;
Reverse pulse duty cycle of 10% (on 0.1 ms, off 0.9ms), working time 10ms, an average current density of the reverse peak current density of the positive peak current density of 1 to 2 times, obtained by calculating backwards.

But many people believe that when acidic gold plating, because the gold anode insolubility, reverse peeling double pulse does not work, so the use of the double pulse is superfluous. In fact, the double pulse reverse reeling gold plating only improve the uniformity small, but it can not say that is superfluous, or can not say there is no significance. There is a small experiment may indicate the presence or absence of other dual pulse gilded significance. In the same acidic gold plating solution, the same current density, respectively, DC power source, single pulse, double pulse at the same time each plating a test piece. Comparison of three test pieces, can see clearly that the plating coating brightness is incrementally from DC to single pulse and then to double pulse power supply gold plating.

This shows dual pulse reverse stripping gold plating for improving the crystallization is advantageous, otherwise adopting double pulse plating will not more bright than the single pulse. This should be due to that though reverse pulse not achieve anodic dissolution, but can play the role of electro-polishing, which facilitates the subsequent cathodic deposition coating pulse period is more detailed, bright.

Further, reverse pulse may also have the plating coating be more fully in the subsequent recrystallization cathode pulse period effect, and thus the plating layer coating will be finer grain.

But the reverse pulse work time shall not too long (less than 1/10 of the positive pulse time), otherwise the deposition rate is slow. Also, reverse pulse peak current density should not be less than the positive pulse, otherwise reverse electro-polishing effect is not obvious. Double pulse barre plating as well. Decorative gold plating barrel plating time is short, thin plating coating, good brightness Ni underlying coating nonfunctional requirements, so generally not suggest the use of pulse power supply plating, in order to save the cost of expensive pulse rectifier. But production practice shows that, use double pulse power supply gold plating, if select parameter properly, plating time can be shortened more than 1/3, so as to achieve the effect of the save gold.

Pulse power supply Overview:

Pulse power supply plating is a powerful means of external bath for metal electrodeposition. It uses the time function to improve the physical and chemical properties of plating coating by changing the pulse parameters, therefore to achieve saving of precious metals and obtain a functional electroplating layer coating purposes. Pulse reverse power supply belonging to a modulation current pulse electro plating, the current it uses is a fluctuation or continuity DC impulse current, so pulse reverse power supply plating is essentially an on-off DC plating.

Pulse power supply waveform type:

There are a variety of Pulse reverse power supply current waveform, the common are square-wave, triangle, ramp, ladder wave. However, the current application, typical pulse reverse power supply generating square wave pulse current is widely used. Thus, the study of pulse plating are generally carried out around the square wave form.

Pulse power supply waveform

Pulse power supply waveform

Modulation current power supply plating:

Traditional electro plating is generally as direct current, referred to as DC. DC current is a current direction does not change with time, there is only parameter can be set–current or voltage. DC current waveform common as single-phase half-wave, single-phase full-wave, three-phase half-wave, three-phase full-wave DC or steady current, etc., commonly to generate these waveforms plating power supply have: silicon rectifier, thyristor rectifier, high-frequency switching power supplies etc..

Disadvantage of DC rectifier compare with pulse power supply:

Not difficult to see, DC with feature of current continuity or duration, not interrupted or changed over time, thus the use of only one parameter – current or voltage to be adjusted. This makes the DC current as a means outside bath control plating quality lack of strength. For example, the DC current are useless in cathode current density increase, inhibit side reactions, and reduce the content of impurities in electroplating, as well as to improve current distribution, etc.

After alternating with pulse signal other signal modulation DC current called as modulation current, modulated current used for plating is called modulated current plating. Modulated current plating existed as mainly used for outer plating tank quality control, it can often play the role that DC rectifier plating can not achieve quality. For example, pulse power supply plating increase several times or even ten times than DC plating cathodic current density, and get detailed crystal plating coating. Modulation current pulse plating generally has: pulse plating, asymmetric exchange plating, DC superimposed plating cycle pulse reverse electroplating.

Hard oxidation rectifier

Hard oxidation

Hard oxidation and ordinary oxidation difference: Hard anodized oxide film has 50% penetration inside the aluminum products, an another 50% attached to the aluminum workpieces surface, so after a hard anodizing exterior of the product size becomes bigger, the hole becomes smaller, while after hard oxidation the external dimensions of ordinary oxidation becomes smaller and the hole becomes bigger.

Hard oxidation colors:

Hard oxidation colors usually made of black and oxidation film true colour (natural color), true color is determined by the aluminum alloy composition, even the same type of aluminum ( for example 6061-T6), and different manufacturers, the color of the oxide film is different, if Aluminum use same manufacturer the same type of material maybe colors are different, and therefore, the true nature of the oxide film is generally used for the internal parts of the product.

Hard oxidation aluminum advantages:

1, Aluminum hard anodizing surface hardness can even up to HV500, which can compare to chrome plating;
2, The hard anodizing film thickness from 25 to 250um;
3, Have features of strong adhesion, according to the generated hard anodized oxidation characteristics: hard oxidation film has a 50% penetration in aluminum inside,
50% adhered to the surface of an aluminum alloy;
4, Good insulation: breakdown voltage up to 2000V;
5, Great wear resistance: for if copper content more than 2% in aluminum alloy, its maximum wear index of 3.5mg/1000rpm. All other alloys wear index should not exceed than 1.5mg/1000rpm;
6, Non-toxic: the oxidation film and for anodic oxide film produced by an electrochemical process there is no toxic to humans.

So now a lot of industry in order to facilitate machining and reduce the weight of products, and environmental protection requirements, some hard oxidation aluminum alloy parts products are currently to replace stainless steel, and conventional spray, plating treatment process.

Pulse rectifiers silver plating

Pulse rectifiers silver plating

Pulse rectifiers silver plating:

Normal silver electroplating machine can’t obtain bright plating coating directly, in order to get brightness need chemical dip or barrel rolling treatment, but will cause silver electroplating coating loss, and difficult to recover 50% of loss, resulting in a greater waste. Bright silver plating can obtain bright plating coating directly, which simplifies operation and reduces waste, but electro plating coating antitarnishing worse, and conductivity deteriorates. Because silver in the air due to the sulfur can easily change color, additives, mostly as sulfur compounds, attached to plating coating inevitably promote its easier to change color, thereby seriously affecting the electrical plating and welding properties. Furthermore, the plating agent attached (in this case the agent can be regarded as impurities) make the silver plating layer impure, electrical properties then decrease. To make an inappropriate analogy, cold medicine to cure a cold, but comes with side effects (such as dizziness, drowsiness, etc.). Bright silver palting solution additives like cold medicine, the use of which may obtain directly bright silver plating layer, but side effects (such as anti-tarnish coating capacity, electrical conductivity variation, additive decomposition products difficult to handle, etc.).

Silver plating pulse rectifiers

Silver plating pulse rectifiers

About brightness silver plating side effect problem, the connector industry has been pointed out, the inner and outer conductor of the RF connector using bright silver electroplating, have a greater impact to products environmental resistance and electrical conductivity. In silver plating process also found bright silver plating pieces changing coler fast thant chemical dipping bright or barrel tumbling process type.
Of course, can adopt passivation, immersion silver anti-discoloration agent, or both, and use other measures of bright silver plating coating for anti-color processing, but this is only remedial measures, can not change its attached staff that its nature of sulfur compounds that can cause discoloration or affect other property.
Therefore, if there is high requirements of silver plating coating, generally not advocate the use of bright silver method, some military products (such as aircraft engine bearings protection frame) electroplating silver even prohibited the use of additives. But without additives will not get brightness coating,, while military performance only need the performance not consider brightness, but other products (such as professional electroplating factory processing products) could not deal with like military. Other products even asked for both performance and also the brightness (not using dip or barrel rolling processing) requirements, this is probably some difficulty, it’s something like ask for cold medicine both cure and can not have the side effects.
Some people think of pulse rectifiers silver plating, by using of pulse current in the ordinary silver plating solution to get brightness silver plating coating. Be the case, the pulse current is really an agent both brightness sliver plating and no side effects (good performance) medicine. At first, use a single pulse. Fewer parameters, just turn on, shutdown and peak current, the test soon finished. The result failed, only a single pulse silver plating layer is more detailed than the DC power supply, white, but still dull.
Then consider double pulse. Experts said that if the parameters properly, using double pulse most possible to give a bright nickel plating layer, which in terms of looking for silver-plated medicine is undoubtedly a good news, because if dark nickel-plating use double pulse can be bright, dark silver should be more able to get (anti-cyanide silver plating peel effect is more obvious). But double pulse plating power supply has many parameters, there are positive & negative turn on/off, shutdown and peak current and the positive/reverse working time, and the positive and negative parameters may differ from each other, if all together will be a huge number, so look for a dark silver get bright plating coating were not as simple as a single pulse. At present, dual pulse plating dark silver no matter experiment or production, used commonly parameters, but did not explore deeper, the result certainly will not get bright silver plating. Nevertheless, the double pulse current dark silver-plating get some inspiring results.
It is believed more than one person has done such a test, or have such experience: compare with DC rectifier, single pulse, double pulse dark silver plating machine, DC’s silver no brightness, while single pulse rectifier delicate, white, but still no brightness, and double pulse power supply has clearly brightness (substantially semi-bright) especially in plating parts high area compare to single pulse, and observed other area of workpiece under the sun will be a reflection of light. But this is a result of the use of commonly parameters, commonly parameters may not be the optimal parameters, if the case of optimum parameters, what will happen?

Barrel plating machine tumbling action functions:
① Increase the brightness electroplating layer coating;
② Allows brightness and color more uniform, hanging plating machine type has been got semi-bright in high zone of electro plating parts, why not barrel plating line type can’t obtain whole bright plating layer coating?

Of course, the outcome need facts speak, but adopts double pulse can achieve both performance and brightness at least have the following meanings:
① The use of pulse rectifiers silver plating, double pulse rectifiers with only a small part of plating chemical solution can obtain bright sliver plating coating, which can greatly reduce the amount of additives, to improve plating coating performance (due to attached less additive and pulse plating dense) and as well as ensure brightness, but also saves expensive additives (amplitude usually 50% to 80%);
② If use a common silver plating line, dark silver double pulse rectifiers roll has been got half-bright electroplating coating, then a slight dip bright light treatment shall be bright, by this way, isn’t silver material waste can be reduced?

Pulse rectifier Pulse rectifier plating principle:

Overview:

Pulse rectifier plating is a powerful tool to control metal outer tank electrodeposition. It uses the time function to improve the physical and chemical properties of the plating coating film by changing the pulse parameters, to achieve savings in precious metals and obtain a functional electroplating coating film purposes. Pulse rectifier electro plating belongs modulation current plating, its current is a fluctuation or on/off DC rush current, therefore, is essentially on-off DC plating. There are a variety of pulsed current waveform, commonly as square wave, triangle wave, sawtooth, order staircase wave etc.. However, in application situation, typical pulse power generated square wave pulse current is widely used.

Pulse rectifier waveform

Modulated current plating:

Conventional electroplating is generally used in the form of direct current, referred to as DC. DC current is a current direction continuous steady and does not change with time changing. DC current waveform common as single-phase half-wave, single-phase full-wave, three-phase half-wave, three-phase full-wave, DC or steady current, etc.. While to generate these waveforms power supply are, silicon-controlled rectifier, high-frequency switching power supplies. DC current with features of continuity or continuity, without interruption to control plating coating film outside the bath. Such as DC current increase cathode current density, inhibit side reactions and reduce the content of impurities in the electroplating coating, to improve current distribution, etc. are useless.

DC current after pulsing signal or other modulating alternating signal is called as modulation current, as well as the plating process under condition of modulation current is carried as modulation current plating. Modulated current plating mainly generated and existed to play a role to control outside bath plating coating quality. It can get the effect that the DC current plating can not achieve. For example, the pulse plating increase several times or even ten times more than direct current plating cathodic density, and get more detailed crystalline coating. Modulation current normally has pulse plating, asymmetric exchange electroplating, DC overlay plating cycle for the several forms of direct plating and so on.

Current pulse plating is actually used by a DC on-off, but when on DC peak current equivalent more than ordinary DC current times or even tens times. it is this high instantaneous current density make the metal ions in the very high overpotential to reduce, so that the grains become fine deposit layer. Pulse rectifier plating is widely used in electronic circuits of the electronics industry, connectors, printed circuit, electroplating integrated framework, the stem, etc., these products can be greatly improved the performance of electronic devices, and significant saving precious metals. Pulse rectifier plating is currently the most widely used and one of the largest gains modulation current plating.
