Company Advantages
1. A-TECH enig pcb finish is designed by our designers making use of their understanding of the market knowledge. Its robust structure allows it to be used in harsh environments
2. Operators are more dedicated to their work when they use this product because they encounter less fatigue and tiredness. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance
3. enig pcb finish optimizes the functions of carbon pcb which also improves the efficiency. It is offered with low dielectric loss
4. With enig pcb finish features, carbon pcb has a good application prospect. It can be manufactured with a customized thickness
5. With the installation of enig pcb finish , carbon pcb have increased its sales. It is characterized by high thermal conductivity and good heat dissipation

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.
