Company Advantages
1. Our professional inspectors and workers ensure the whole production process of A-TECH hasl pcb finish proceed well. It is 100% produced in accordance with IPC-6012 & IPC-A-600F standards
2. Being able to emit natural light which is similar to the sunlight, the product offers users a soft and comfortable lighting environment. Its robust structure allows it to be used in harsh environments
3. [核心关键词 has the characteristics of hasl pcb finish and long life, it may bring social benefits. It stands out for its impact endurance performance
4. The quality of this product is improved under international standards. It can be manufactured with a customized thickness


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.

A-TECH hasl pcb finish is produced under strict scrutinization. It is checked for its material ingredients as well as material extraction methods to guarantee its quality. It shows ultra-high leak-tightness performance
The production of A-TECH enig pcb covers a few steps. The rough concentrate is deeply processed at first to extract some useful ingredients, then the concentrate is further ground for higher purity. It can be customized in terms of size and logo
High-tech processing equipment is used in the production of A-TECH hasl pcb finish. It is done under the detritus equipment, grinding equipment, as well as sand-making equipment, which can guarantee high purity and fineness. It meets the requirement of food safety standards
The raw materials of A-TECH hasl pcb finish are treated with several procedures. Materials enrichment, refining, and smelt process will be conducted to make the materials into a product with high purity. The product will not influence the taste of beer by creating a confined space
A-TECH hasl pcb finish will go through several manufacturing stages. First, the raw materials will be crushed and ground, then they are separated and concentrated to separate the waste ingredients out. 卖点、特色句]
The product is superior in quality and reliable in performance. Its base is firm enough and will not topple easily
