Product Comparison
Compared with other products in the industry, Aluminum PCB has more obvious advantages which are reflected in the following aspects.
Company Advantages
1. A-TECH osp pcb finish has an optimized design. It uses an energy-efficient engine system, a rugged mechanical structure, and a more reasonable plc system.
2. The surface of the product is treated by electrostatic spraying and high-temperature testing. Therefore, this product has a strong performance in electromagnetic shielding and high-temperature resistance.
3. The product contains no harmful materials and can be recycled, which is a more responsible and environmentally friendly lighting choice.
4. The product developed by A-TECH has stood out in the market compared to other products.
5. The product presents an opportunity for building customer trust and winning more business.


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.
