Product Comparison
Compared with products in the industry, A-TECH's Multilayer PCB has the outstanding advantages which are mainly reflected in the following aspects.
Product Details
Adhering to the concept of 'details and quality make achievement', A-TECH works hard on the following details to make the Multilayer PCB more advantageous.
Company Advantages
1. The quality of A-TECH osp pcb finish is improved through a series of mechanical and chemical treatments. They are softening, antibacterial treatment, stain-resistant treatment, antistatic treatment, etc.
2. With the strict quality inspection procedure throughout the whole production, the product is bound to be exceptional in quality and performance.
3. Our professional team strictly performs quality management in the aspect of product quality.
4. immersion gold pcb is produced with high-quality and reasonable price that satisfy clients.
5. The reputation of A-TECH CIRCUITS Co., Ltd. is mostly based on the stable quality of immersion gold pcb .


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.
