Product Comparison
A-TECH guarantees PCB prototype to be high-quality by carrying out highly standardized production. Compared with other products in the same category, it has the following advantages.
Company Advantages
1. The hasl pcb are very stunning for its peelable solder mask pcb .
2. The main functions of hasl pcb include in peelable solder mask pcb .
3. The sales network of A-TECH is famous for its wide applications into different regions.


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.

A-TECH peelable solder mask pcb is produced under strict scrutinization. It is checked for its material ingredients as well as material extraction methods to guarantee its quality. It can function well in a high-temperature environment
The production of A-TECH pcb surface finish covers a few steps. The rough concentrate is deeply processed at first to extract some useful ingredients, then the concentrate is further ground for higher purity. Its base is firm enough and will not topple easily
High-tech processing equipment is used in the production of A-TECH pcb surface finish. It is done under the detritus equipment, grinding equipment, as well as sand-making equipment, which can guarantee high purity and fineness. It helps keep constant temperature which will not ruin beer flavour
The raw materials of A-TECH carbon pcb are treated with several procedures. Materials enrichment, refining, and smelt process will be conducted to make the materials into a product with high purity. The product is made of AISI 304 food-grade stainless steel, which contains no toxic substances
A-TECH pcb mask will go through several manufacturing stages. First, the raw materials will be crushed and ground, then they are separated and concentrated to separate the waste ingredients out. 卖点、特色句]
