Product Details
A-TECH's Multilayer PCB is processed based on the latest technology. It has excellent performances in the following details.
Company Advantages
1. A-TECH peelable mask pcb has been tested for guaranteed quality in an independent laboratory. It meets both domestic and international safety standards for gift&crafts.
2. The quality of this product is guaranteed and has many international certificates, such as ISO certificates.
3. Safety of this product is one of its biggest selling points that cannot be ignored. This product can operate effectively on low-voltage electrical systems, thus, it's much safer for users.


HASL, the full name is Hot Air Solder Leveling, it’s one of the traditional surface finish on printed circuit boards with long successful history.

To make the HASL finish, the circuit boards will be submersed in molten solder(Tin/Lead). This solder will cover all the exposed copper surfaces. Upon retraction from the solder, high pressure hot air is blown over the surface through air knives, this levels the solder deposit and removes the excess solder from the surface of printed circuit boards.

HASL (Tin/Lead) surface finish is not RoHS Compliant, so it can be only available where RoHS exemption is permitted. The typical thickness of HASL is 1-40um, and the shelf life can reach to 12 months.



The advantages of HASL surface finish

● Excellent solderability / wettability
● Good reflow properties
● Low cost in manufacturing
● Large processing window is allowed
● Multiple thermal excursions
● Can be widely used



The disadvantages of HASL surface finish

● Uneven surface
● Not suitable for PCBs with fine pitch
● Thermal shock
● Not RoHS Compliant
● Solder bridge
● Plugged or Reduced plated through holes



A-TECH have HASL surface finish in house, it’s mainly used to build single sided or double sided PCBs with high solderability requirements but low manufacturing cost and without RoHS Compliant requirement.

Inquire now! hard gold pcb is a permanent tenet of A-TECH CIRCUITS Co., Ltd. to improve himself. Inquire now! peelable solder mask pcb is the tenet A-TECH CIRCUITS Co., Ltd. stick to. Inquire now!
The entire manufacturing process of A-TECH enig pcb is strictly controlled. It may be divided into several important processes: the provision of working drawings, the selection&machining of raw materials, veneering, staining, and spray polishing. Some of the Immortals Swan products are designed with organza which can prevent gnats from outside
The creation of A-TECH peelable mask pcb involves some important factors. They include cutting lists, the cost of raw materials, fittings, and finish, the estimate of machining and assembly time, etc. Immortals Swan products are exported to many foreign countries including South America, Eastern Europe,etc
The structure of A-TECH hard gold pcb is checked through various methods of welding tests. These tests include bend testing shear stud, bolt tightening or torque test, magnetic particle inspection test for welding, ultrasonic test for welding, visual test for welding, etc. Raw materials for producing baby products are all eco-friendly
The manufacture of A-TECH enig pcb includes the specific design of the polymer optical component, assembly, concept and prototype testing through to mass production with multiple injection molding processes, optoelectronic assembly, and packing. Different colors like blue, pink,etc. are available
The manufacture of A-TECH hard gold pcb is of professionalism. The multistage production process is adopted. Its design, production, assembly, and testing will be controlled by separate teams. Some of the Immortals Swan products are designed with organza which can prevent gnats from outside
Efficient heat transfer is one of its biggest selling points. The materials' thermal conductivity is high and has relations to their heat dissipation efficiency. Immortals Swan study chair and desk have been widely supplied to famous supermarkets like JUSCO in China
