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.




A-TECH carbon pcb needs to be checked and evaluated. It is checked with regard to shrinkage, oil and water repellency, print durability, seam performance, and side seam twist performance. It does not breed bacteria, which reduces the risk of cross-contamination
A-TECH carbon pcb is developed combining both aesthetics and practicality. The design gives considerations to function, materials, structure, dimension, colors, and decoration effect to space. It can be treated to be hydrophilic or hydrophobic
The fabric quality testing of A-TECH carbon pcb has been conducted. The testing mainly includes the aspects of construction weight, fiber content, strength properties, dimensional stability, and flammability. Made of degradable materials, it is eco-friendly
The quality of A-TECH enig pcb finish is guaranteed by a wide range of quality tests. It has passed wear resistance, stability, surface smoothness, flexural strength, acids resistance testings that are quite essential for furniture. With good air permeability, it is less likely to create odors
The fabrics for A-TECH enig pcb finish is carefully selected. Only those with high strength, good tearing strength, elasticity, and resistance to chemical liquids are chosen. It has the ability to prevent oils from penetrating into it or from sticking to its surface
This product is in accordance with the quality standards of the industry. With good air permeability, it is less likely to create odors
