Product Details
A-TECH's Multilayer PCB is processed based on advanced technology. It has excellent performances in the following details.
Company Advantages
1. A-TECH immersion tin pcb undergoes a series of production methods such as sanding, painting, and ovendry. All these methods are strictly carried out by our professional workers.
2. Carefully designed by professionals, immersion tin pcb disperses the pressure of the forefoot and the heel, increases the force area of​the sole, and greatly reduces the fatigue of the foot during walking.
3. This product has premium quality and rich functionality.
4. Fast delivery methods enable A-TECH CIRCUITS Co., Ltd. to gain a reputation in the domestic and international markets.


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.
