high quality immersion silver pcb carbon free delivery for wholesale

Company Advantages
1. When manufacturing immersion silver pcb , we also take osp coating pcb into consideration.
2. This product does not warp, curl or cup. And it is naturally resistant toward mold, mildew, and microorganisms even in the consistently 'wet' weather.
3. The product is free of electric leakage problems. Its circuit design has been optimized with an insulation protection system that would prevent any electrical risk.
4. A well-designed room that has this product will give a great visual impression to many guests, leaving a good impression on them.
5. With good shock absorption function, the product helps prevent ankle, tendons and ligament injuries. It contributes a lot to maintain healthy feet.

Hard gold plated, the full name is Electrolytic Nickel Electrolytic Gold. The most common application of hard gold plated is edge connectors(gold fingers), and it may also be plated over the entire circuit boards.

Hard Electrolytic gold consists of a layer of gold plated over a barrier coat of nickel. Hard gold is extremely durable, so it is most commonly applied to high-wear areas such as gold fingers and keypads.

Hard gold is not generally applied to solderable areas, because of its high cost and its relatively poor solderability. The maximum thickness that IPC considers to be solderable is 17.8U”, so if this type of gold must be used on surfaces to be soldered, the recommended nominal thickness should be about 5-10U”.

The advantages of hard gold plated

● Hard, Durable surface
● RoHS Compliant
● Long Shelf life
● Excellent for high-wear products

The disadvantages of hard gold plated

● Additional high cost
● Extra complicated manufacturing process
● Etching undercut can lead to slivering/flaking
● Finish does not fully encapsulate trace sidewalls, except in gold finger areas

A-TECH is capable of using hard gold plated on both of gold fingers and the entire PCB, the typical thickness of hard gold plated for gold fingers can be 0.1 – 3.0um, and the typical thickness of hard gold plated on entire board is 0.1 – 1.27um.
