Company Advantages
1. The quality standard of A-TECH enig pcb finish complies with various regulations. They are China (GB), the US (BIFMA, ANSI, ASTM), Europe (EN, BS, NF, DIN), Australia (AUS/NZ, Japan (JIS), Middle East (SASO), among others. It has high tensile strength and can be deformed without breakage
2. Requiring little repairs and maintenance, the product helps manufacturers save maintenance money and time in the long run. The product has the performance of great stability
3. The product is heat resistant. The materials used in it have superior conductivity for heat and relatively high thermal emissivity. It is characterized by high thermal conductivity and good heat dissipation
4. The product has an excellent heat dissipation effect. The groove design maximizes the contact space between the device and the heat to dislodge the heat out. Its solder mask can be offered with green, blue, white, black, yellow, and red colors

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.
