A-TECH lead hasl pcb bulk production for wholesale

Company Advantages
1. A-TECH tin plating pcb is manufactured with high precision in order to meet the set industry standards. Its robust structure allows it to be used in harsh environments
2. This product has been extensively preferred by homeowners, builders, and designers thanks to its aesthetics and functionality. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density
3. The product features high efficiency. The ammonia refrigerant used has a prominent cooling capacity, which is better than other refrigerants. It is characterized by high thermal conductivity and good heat dissipation

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.
