Enterprise Strength
  • A-TECH receives wide recognition and enjoys a good reputation in the industry based on pragmatic style, sincere attitude, and innovative methods.
Company Advantages
1. The creation of A-TECH pcb mask is strictly conducted. The cutting lists, the cost of raw materials, fittings, and finish, the estimate of machining time are all strictly taken into consideration advance.
2. This product is known for its durability. It can withstand a certain number of cycles and maintain its performance after a long period of operation.
3. The strengths of its materials mean this product is tear-proof, will not lose its qualities after washing and can last for years.
4. It is opaque, neither too thin nor too thick or heavy, which provides wearers with enough coverage and protective function.


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.
