Company Advantages
1. Each production phase of A-TECH peelable solder mask pcb is strictly supervised. It totally conforms to the UL Flame Rating of 94V-0
2. It is soft to touch with additional comfort for wearers' skin, especially for those who are prone to have skin redness or itchy. It has high tensile strength and can be deformed without breakage
3. immersion tin pcb can be relatively peelable solder mask pcb , and provides features like lead free hasl pcb. It is offered with low dielectric loss
4. Compared with the other similar products, immersion tin pcb has a lot of advantages, such as peelable solder mask pcb . Its robust structure allows it to be used in harsh environments

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.
