A-TECH high quality pcb mask bulk production at discount

Company Advantages
1. Risk analysis for the fabrics used in A-TECH hard gold pcb will be carried out. The analysis will check whether the ingredients in the fabrics are harmful and toxic and whether it causes pollution after being disposed of.
2. Its developing requires stringent testing to ensure quality and performance. Only those that pass rigorous tests will go to the marketplace.
3. This product provides opportunities for significant reductions in building energy use and CO2 emissions, while at the same time having a positive impact on the quality of the indoor environment.

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.
