Company Advantages
1. A-TECH osp pcb is produced adopting new environmentally-friendly materials. It is characterized by high thermal conductivity and good heat dissipation
2. Any hair, fur, leaves, sand particles, or other stubborn stains in the swimming pools can be effectively removed by using this product. It stands out for its impact endurance performance
3. It delivers good building energy performance. Relative performance is measured when possible using various analysis software such as Ecotect and EnergyPlus. Designs are tuned based on the results. It is offered with low dielectric loss
4. The product has short circuit protection. It is equipped with a fuse protector that can protect the main components from damage caused by overcurrent. With a compact design, it is space-saving
5. The product has excellent drape effect. The Adopted three-dimensional cutting or stereo clipping technique drape the soft lines of the fabric. It can reduce the electrical signal loss and provides the highest efficiency


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.
