Product Comparison
Compared with products in the same category, Multilayer PCB we produce is equipped with the following advantages.
Company Advantages
1. A-TECH [lead free hasl pcb undergoes curing and post-curing of epoxy resin. Post-curing is highly essential for bonding epoxy resin with a printed circuit board(PCB), meanwhile, it is also a thermal aging process for LED.
2. The product features great sound reduction. The retractable top and the bottom seal greatly contribute to the reduction of sound.
3. The product can stand up a certain degree of voltage. It has passed the Dielectric Withstand Test by applying high voltage on power and ground terminal circuit to measure its collapse status.
4. This product greatly caters to the industry development and market demand.
5. Over the years in the market, this product has received no complaints from our customers.


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.
