Company Advantages
1. The design of A-TECH tin plating pcb is first prepared on the latest CAD software. Then, our renowned designers verify these designs to meet the requirement of standards in the sanitary ware in the industry. Its robust structure allows it to be used in harsh environments
2. pcb mask will be strictly tested by our experienced QC team before its packing. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density
3. This product can maintain a clean surface. Its fabrics are highly anti-static, which does not allow the dust to adhere to the surface. The product can be resistant to corrosion
4. This product will not accumulate odor. It is made of antimicrobial fabric that inhibits the growth of unpleasant odors by controlling bacterial growth. With a compact design, it is space-saving
5. This product features thermal comfort. It has insulation properties due to the presence of a large number of small air pockets between interlacements of warp and weft yarns, preventing air from migrating through its fabrics. It totally conforms to the UL Flame Rating of 94V-0


OSP, the full name is Organic Solderability Preservative, it preserves the copper surface from oxidation by applying a very thin protective layer of material over the exposed copper usually using a conveyorized process. It uses a water-based organic compound that selectively bonds to copper and provides an organometallic layer that protects the copper prior to soldering. It’s also extremely green environmentally in comparison with the other common lead free finishes, which Suffer from either being more toxic or substantially higher energy consumption.

The typical thickness of OSP is 0.2 – 0.65um and the shelf life is 6 months. It’s a simple manufacturing process to make OSP, and like HASL finish, the production cost of OSP is lower than most of other surface finishes.



The advantages of OSP 

● Cost effective / Low cost
● Simple process
● Excellent flatness
● Re-workable
● Clean, environmentally friendly process



The disadvantages of OSP

● Short shelf life
● Very sensitive to handling – gloves must be used and scratches avoided
● Short operating window between assembly stages
● Not suitable for multiple soldering processes
● Difficult to inspect or measure thickness



A-TECH own OSP line in house, it’s nowadays mainly used to build single-sided FR4 PCB or aluminum PCB with low cost requirements.
