Is the conductivity efficiency of copper plating better or worse than that of silver?
Q: What is the conductivity efficiency of copper plating? A: Among metals, copper has the second-best electrical conductivity after silver.
Can you create a copper plating that does not discolor with Silvec?
Q: Is it possible to create a copper plating that does not discolor? A: Ultimately, it will discolor. There are methods to minimize and delay discoloration as much as possible, but copper plating will eventually discolor.
What are the characteristics of the various baths for copper plating at Silvec?
Q: There are various baths for copper plating; what are the characteristics of each? A: Copper sulfate plating: This plating has high smoothness for decorative purposes, allowing it to mask minor scratches and achieve a mirror finish. It is also used for circuit formation in printed circuit boards. Cyanide copper plating: This plating solution contains highly toxic cyanide, and its use has gradually decreased. However, it is an alkaline plating solution with excellent uniform electrodeposition, strong adhesion to impurities, and is essential for plating on zinc alloys. Pyrophosphate copper plating: This plating solution has become popular as an alternative to cyanide copper plating. It has excellent uniform electrodeposition and is suitable for carburizing prevention and electroforming, but its use has decreased due to the difficulty of wastewater treatment (copper removal).
If copper plating is done with Silvec, will cyanide remain after the copper plating?
Q: In the case of cyanide copper plating, does cyanide remain after copper plating? A: Cyanide is not contained in the copper plating film.
Can a hard copper plating with a coating be done at Silvec?
Q: Is it possible to have a hard copper plating with a film? A: It is possible to have a copper plating with a hardness higher than pure copper (around 55HV) (up to about 180HV).
Is it not possible to directly copper plate aluminum die cast?
Q: I was told that nickel plating is necessary as a base layer when requesting copper plating on aluminum die casting. Is it not possible to directly copper plate aluminum die casting? A: It is possible. Our company can directly copper plate as well as directly nickel plate aluminum alloys. However, pretreatment (zincate treatment) may be required. We look forward to your requests for sample creation and technical consultations.
Can aluminum material be nickel plated in barrels at Silvec?
Q: Is it possible to nickel plate aluminum material using a barrel? A: Yes, it is possible at our company. Depending on the shape and size of the aluminum, the cost-effectiveness of plating using fixtures versus plating using a barrel will vary. We will review the product drawings and shapes to suggest which method would be more cost-effective, as well as discuss the differences in quality. In addition to the price difference, the performance benefits of having a complete plating coating without fixture contact, and the effectiveness of barrel plating for cylindrical products to ensure plating reaches the inner diameter, are significant.
Can we change the glossiness even with nickel plating at our company?
Q: Is it possible to change the glossiness even with nickel plating? A: It is possible to change the glossiness through gloss agent management and plating thickness management. However, it also depends on the glossiness of the base material.
Is it true that applying nickel plating over tin plating is effective in preventing metal diffusion into electronic components such as contacts and connectors?
Q: Is it true that nickel plating on a tin-plated substrate is effective in preventing metal diffusion into electronic components such as contacts and connectors? A: Yes, it is effective. For example, by inserting a nickel plating between copper plating and tin plating, the nickel plating layer can act as a barrier to prevent copper diffusion into the tin plating layer.
Please tell me the advantages and disadvantages of the double nickel.
Q: Please tell me the advantages and disadvantages of double nickel. A: The advantage is that it has superior corrosion resistance compared to single-layer nickel plating at the same plating thickness. The disadvantage is that it increases the number of processes, leading to higher costs.
![Is it possible to have nickel plating that doesn't break with a rivet? [Video available]](https://image.mono.ipros.com/public/product/image/acf/2000809903/IPROS02255139257129568299.png?w=280&h=280)
Is it possible to have nickel plating that does not crack during riveting after electric nickel plating?
Q: When crimping after electric nickel plating, the nickel plating film cracks. Is it possible to have a nickel plating that does not crack during crimping? A: It is possible with our company. Regular bright nickel plating often cracks during crimping due to the film stretching at a hardness of around HV550-600. Our nickel plating can achieve a nickel plating that does not crack during crimping by depositing a plating film with good ductility. We would be grateful if you could feel free to contact us or request sample creation.
Is it possible to directly nickel plate zinc die castings at Silvec?
Q: Is it possible to directly nickel plate zinc die castings? A: No, it is not possible. Zinc die castings require copper plating as a base layer. Once copper plating is applied, various types of plating can be selected.
Please tell me about a plating that does not cause whiskers and has good solderability.
Q: Please tell me about a plating that has good solderability and does not produce whiskers. A: Silvaco's "Solderable Nickel Plating" has solder wetting properties equivalent to tin plating, does not produce whiskers, and is a cost-effective plating option. Precious metal platings (such as gold, silver, and platinum) also have good solderability and do not produce whiskers, but they are expensive.
What will happen if nickel plating is not applied to the substrate? 【Chrome plating】
Q: What happens if nickel is not applied as a base layer? 【 Chrome plating 】 A: I will answer in the context of decorative plating. It is possible to perform chrome plating without a base nickel layer, but there are many disadvantages such as not achieving gloss, and inferior corrosion and wear resistance. Therefore, a base nickel plating is necessary for decorative chrome plating.
I would like to have a mirror finish with chrome plating at Silvec. Is that possible? 【Chrome plating】
Q: I would like to have a mirror finish with chrome plating; is that possible? A: Yes, it is possible. By polishing the material to a mirror finish and applying a glossy nickel plating as a base before the chrome plating, a mirror chrome finish can be achieved. In the case of hard chrome (industrial chrome) plating, a mirror finish polishing is performed after plating. Our company mainly specializes in decorative chrome plating.
