A-TECH high quality tin plating pcb factory for wholesale

Company Advantages
1. During the production of A-TECH tin plating pcb , it has gone through heat and surface treatments: hardening, induction hardening, chemical browning, and electroless nickel plating. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination
2. A-TECH CIRCUITS Co., Ltd. has persistently uphold the principle of 'good service, quality guarantee, and prompt delivery' . The inner layer core of the product is chemically treated for improved adhesion of the copper surface
3. This product can be placed in convenience stores, restaurants, grocery stores, retailers, schools and any other location to educate or convince the consumer. It is vacuum-sealed, which can greatly reduce the bulk of the overall cargo
4. The product has reliable performance. It is not likely to burn out or generate any leakage when there is a sudden blackout. It is offered with low dielectric loss

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.
