Company Advantages
1. All of the components or parts of A-TECH are made of moisture resistant materials which meet the lowest of formaldehyde emissions standard in the kitchen cabinet industry. It has high tensile strength and can be deformed without breakage
2. This product helps keep users comfortable and dry through wick away moisture from night sweating. There would be no more sleeplessness with this product. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance
3. The product is skin-friendly. The fibers have a smooth feel and a natural wicking action that keeps moisture away from the skin. It has low water absorptivity in the damp environment
4. The product has the advantage of corrosion resistance. When it is subjected to the atmosphere, it won't react with the air. It is extremely popular in the markets of Europe, North America, and Asia


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 PCB 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.
