Application Scope
Aluminum PCB developed and produced by our company can be widely used in various industries and professional fields.A-TECH has been engaged in the production of PCB prototype for many years and has accumulated rich industry experience. We have the ability to provide comprehensive and quality solutions according to actual situations and needs of different customers.
Company Advantages
1. A-TECH tin plating pcb is manufactured with quality components and parts. The workmanship of components and parts is controlled and inspected with professional technicians to guarantee they will not ruin the board after soldering.
2. enig pcb can be used in tin plating pcb , and has an extensive application prospect.
3. Compared with normal enig pcb , tin plating pcb possess the combination of excellent performance and long service life.
4. What distinguishes this high-quality product from low-quality ones is the fact that it not only looks trendy but also it feels comfortable on the skin.


Immersion Tin, or Chemical Tin, it’s a RoHS Compliant metallic finish deposited by a chemical displacement reaction that is applied directly over the basis metal of the circuit board, the immersion Tin protects the underlying copper from oxidation over it’s intended shelf life, copper and tin however have a strong affinity for one another, the diffusion of one metal into the other will occur inevitably, directly impacting the shelf life of the deposit and the performance of the finish. The negative effects of tin whiskers growth are well described in industry related literature and topics of several published papers.

The typical thickness of Immersion Tin is ≥1.0UM and the shelf life is 6 months. The cost of Immersion Tin is more expensive than HASL but less expensive than Immersion Gold and close to Immersion Silver. Similar to Immersion Silver, Immersion Tin is also sensitive in handling and storage, it requires PCB manufacturers to control and pack PCBs with Imm Tin more carefully.



The advantages of Immersion Tin

● Excellent flatness
● Mid range cost for lead free finish
● Good for fine pitch / BGA / smaller components
● Top choice for press fit technology
● Reworkable



The disadvantages of Immersion Tin

● Very sensitive to handling – gloves must be used
● Exposed Tin on final assembly can corrode
● Not good for multiple reflow/assembly processes
● Aggressive to soldermask – soldermask dam should be more than 5mil
● Baking prior to use can have a negative effect



A-TECH is capable of using Immersion Tin, we make the profile and electrical test before the process of Immersion Tin finish, and we use papers to separate each piece of boards to avoid scratches during package and transportation.
