Product Information of OSP PCB
Company Advantages
1. The manufacturing process of A-TECH immersion silver pcb finish includes several stages. The product will go through mold fabricating, injection molding, stamping, surface treating, and assembling. The inner layer core of the product is chemically treated for improved adhesion of the copper surface
2. One of our customers said: 'thanks to its fully automatic pre-treatment system, this product has greatly helped me reduces labor cost and maintenance cost.' Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination
3. The product is functional with perfect and reliable performance.
4. The product meets up with international standards for quality and you can be assured of its performance and durability. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density


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.
