Company Advantages
1. A-TECH [核心关键词 is able to operate stably at high drive currents thanks to the improved encapsulation and chip technology. This technology has been well accepted in the LED lighting industry. It is extremely popular in the markets of Europe, North America, and Asia
2. One of the most obvious characteristics of this product is that it has attracted more and more customers. It totally conforms to the UL Flame Rating of 94V-0
3. The product performs well in heat resistance. The materials used in it have a high coefficient of heat conductivity and a relatively low coefficient of linear expansion which make it not prone to fracture under high temperature. It has passed AOI which ensures there will be no errors or welding defects
4. The product features a low discharge rate. The electrolyte in the battery is highly pure and contains no impurity which affects the performance of the battery. 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.
