Company Advantages
1. Keeping updated in technology is vital for our R&D team. A-TECH hasl pcb finish is procuced adopting with our latest chip processing technology. Owing to the repaid change in the LED lighting industry, the R&D team holds a regular investigation into the market demands, so as to provide customer-oriented products. Its robust structure allows it to be used in harsh environments
2. People can benefit equal nutrients from the dehydrated food by this product. The nutrients ingredients have been inspected to be the same as pre-dehydration after the food is dehydrated. It has low water absorptivity in the damp environment
3. The product has no imperfections. In the process of molding, the prototypes are clean and crisp, thus it is free of defects. 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 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.
