A-TECH high quality osp pcb free delivery at discount

Company Advantages
1. A-TECH lead free hasl pcb has ensured quality. Strict inspections are carried out after the production to eliminate any potential quality problems.
2. It has superior quality in water and moisture resistance. Its water-proof capacity enables its inner components from damp which easily leads to electric leakage.
3. Because the product is well-known for its performance in cutting energy use, from a long-term consideration, it is definitely a preferred choice for those who use it frequently.
4. Being a not easy-to-buy option, the product loved by most people due to its uniqueness. Some customers even said that it sold out within days.

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.
