Company Advantages
1. The design & engineering team of A-TECH enig pcb finish applies state-of-the-art software and 3D mechanical CAD programming to finish the design from conception through completion. It totally conforms to the UL Flame Rating of 94V-0
2. The quality of enig pcb finish also shows our professional craftsmanship. Its solderable surface is protected from the oxidation
3. Any deviation of the product will be immediately corrected by our QC experts. Its solder mask can be offered with green, blue, white, black, yellow, and red colors
4. The product is tested under the vigilance of our proficient professionals who clearly know quality standards in the industry. It is vacuum-sealed, which can greatly reduce the bulk of the overall cargo
5. enig pcb finish is produced according to GB and IEC standards. It is offered with low dielectric loss


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.
