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.




Company Features
1. A-TECH CIRCUITS Co., Ltd. has been engaging in developing and mass-producing peelable solder mask pcb . We have gained recognition of the industry.
2. So far, we have won trust from customers around the world. We have been cooperating with them for years, and our workflows are smooth because we always know exactly customers' demands.
3. We have established a sustainable way to conduct our business. We consciously minimize the environmental impact during the entire life cycle of our products, including recycling and disposal.
The development of A-TECH lead free hasl pcb considered several key mechanical properties. It is developed with the stiffness, strength, hardness, ductility, and toughness which are critical for its operation.
A-TECH lead free hasl pcb is manufactured under several processes. Namely, it goes through mechanical drawing (auto CAD), stamping, coating, painting, drying, polishing, testing, and assembling.
During the design stage of A-TECH peelable solder mask pcb, different factors have been considered, including structural configuration, structure connectivity and interface, structural stiffness and associated mechanical performance.
A-TECH peelable solder mask pcb is manufactured by different machining workmanship. It has to be punched, bent, stamped, sawed, ground and honed under corresponding machines.
A-TECH lead free hasl pcb has passed the process evaluation. Evaluate stitches, structures, accessories and fasteners, decorations, shadows in it, pattern continuity, tape, and lining.
The product consumes little energy when working. It can transform little physical or electrical energy into enormous mechanical energy to finish its tasks.
