A-TECH highly-rated pcb surface finish free delivery at discount

Company Advantages
1. A-TECH pcb gold plating is inspected and scrutinized using different methods. It will be scrutinized by sight check or testing equipment for its dimensions, position, non-destructive inspection, and mechanical properties.
2. The product is guaranteed to meet the production standards on quality.
3. pcb surface finish is manufactured based on superior materials. It has good corrosion resistance, heat resistance, explosion-proof and sealing performance. By virtue of built-in battery pack, it has large capacity, high power, and excellent charge and discharge performance.
4. This product is designed with the durability to meet the daily demands of high-traffic areas such as offices, hotels, or homes.

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.
