Application Scope
The Aluminum PCB developed by A-TECH is widely used in industry.While providing quality products, A-TECH is dedicated to providing personalized solutions for customers according to their needs and actual situations.
Product Details
A-TECH's PCB prototype has excellent performances by virtue of the following excellent details.
Company Advantages
1. Every A-TECH enig pcb finish is guaranteed by a series of processes including raw material extraction, accurate and rigorous prototyping and regular tests on physical and chemical properties.
2. This product has good thermal stability. It is not easily prone to color fading or performance changes in high-temperature environments.
3. Because of its outstanding durability, even though it is used for a long time, people don't have to replace it frequently.
4. The product that I bought 2 years ago still looks lubricous and lustrous, even though I rarely put the lubricating oil on it. One of our customers said.


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.
