Company Advantages
1. Compared to others, pcb surface finish have longer service life for immersion tin pcb finish material. The product can be resistant to corrosion
2. The product has the advantage of quickly catching the customer's eyes. It gives the customer a reason to pick up goods and make the purchase. It can reduce the electrical signal loss and provides the highest efficiency
3. The product is hypoallergenic. The key ingredients are tested to be free of allergens, which has been proved by the professional dermatologists.
4. The product will not easily become dark. It is less likely to contact with the surrounding elements, forming an oxidized surface which will make it lose its luster. A smooth part is added on its PTH line to reduce the roughness of through hole
5. The product produces no side effects. It is clinically tested to be free from any harmful substances that would probably pose potential risks to people. The product is certified under UL(E357001) and RoHS


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 applications of thick copper PCBs

● 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.
