A-TECH solder osp pcb cheapest factory price at discount

Company Advantages
1. The production process of A-TECH peelable solder mask pcb is under the real-time monitor. It has gone through various quality tests including tests on the effect of compressed air and condenser water.
2. The product features excellent softness. The fabric is chemically treated by using chemical softener which absorbs the hard substances on the surface.
3. The product is user-friendly. The wood materials used in it is smooth to touch and its design is timeless, safe and fashion.
4. Energy efficiency is one of the selling points of this product. It consumes less power than conventional lighting, which helps to reduce lighting costs.

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.
