3. enig pcb finish makes enig surface to be able to process tasks comprehensively and efficiently. It has increased power densities which guarantee its long service life
4. enig surface is considered as the most promising enig pcb finish for enig pcb finish . Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance

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.

What are raw materials for countersink pcb production?

If this question is asked, you will think about cost, security and performance of countersink pcb . A producer is expected to confirm the source of raw material, decrease the cost for raw material and apply innovative technology, in order to improve the performance-cost ratio. Now most of the manufacturers would examine their raw materials prior to processing. They may even invite third parties to check the materials and issue test reports. Stable partnerships with raw material suppliers are of great relevance to the countersink pcb makers. This usually means that their raw materials will be guaranteed by price, quality and quantity. A-TECH CIRCUITS Co., Ltd. is an important production base of single-sided PCB, especially single layer pcb. A-TECH's main products include osp pcb series. The product is bacteria and fungi resistant. During the cleaning stage, it has gone through antibacterial and sterilization treatment, and the surface is finely polished to a very smooth level, which can effectively kill the bacteria. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density. It can be provided in various sizes and color depending on the customer’s requirements. A smooth part is added on its PTH line to reduce the roughness of through hole.We want to be a trusted partner, providing our customers with high-quality services and offering them the best possible support.

What properties are needed in countersink pcb raw materials?

The raw materials should have the properties that contribute to the overall performance and quality of the product itself and the production process. The raw materials also should not do harm to workers, and damage equipment and the environment seriously during processing. countersink pcb manufacturers should carefully test their raw materials to see if they meet the production requirements and safety and quality standards and if they have the desired properties that benefit the usability and durability of countersink pcb . The tight network of production bases, sales and service training stations of A-TECH CIRCUITS Co., Ltd. is throughout the country. A-TECH's main products include blind vias pcb series. The product is easy to wipe clean. The materials used features enough airtightness, which creates a barrier on the surface for the dust to get in. With a compact design, it is space-saving. It is available in varied specification as per the different demands of the clients.
