highly-rated hasl pcb air bulk production at discount

Company Advantages
1. hasl pcb has reliable quality, refined and beautiful appearance and long service life. A smooth part is added on its PTH line to reduce the roughness of through hole
2. The product offers enough rooms and elasticity for people to wear on. In addition, it can closely follow all the body’s movements. It has high tensile strength and can be deformed without breakage
3. Its fabric shrinkage is very low. After the fabric is steamed or atomized, it is mechanically extruded and dried to reduce the shrinkage rate to less than 1%. The product has the performance of great stability
4. The product features a reliable operation. It is mainly controlled through computers. Unless maintenance is needed, it can go on without any break. It has low water absorptivity in the damp 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.
