Company Advantages
1. The design of A-TECH immersion tin pcb is made with an inspiration board and a mood board. The inspiration board focuses on the details, colors, textures, specifics, etc. and the mood board focuses on the style, emotional scenario, or ambiance of this product. The product can be resistant to corrosion
2. Overall, a high quality immersion tin pcb always attracts many customers. It can be manufactured with a customized thickness
3. The product features a cloud control interface. The function modules on the cloud and customized selections can be adjusted and optimized easily.
4. The product features great shock-resistance. Its toe cap has been tested to be strong enough to resist impact and compression. Its solder mask can be offered with green, blue, white, black, yellow, and red colors
5. The product is not easy to build up the heat. Its components are designed to effectively draw the heat out of the light and then transfer it into the air. With a solder mask, it enjoys a good electrical insulation property


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.
