Company Advantages
1. The manufacture of A-TECH immersion silver pcb meets a very high hygienic standard. The product has no such nature that the food is in danger after dehydration because it is tested for many times to guarantee the food fits for human consumption. It is widely used in different electronics industries, such as telecommunication and consumer electronics
2. The product is incredibly popular among people's daily life. People can find it in electro cars, laptops, cell phones, and iPods. It totally conforms to the UL Flame Rating of 94V-0
3. With a recognizable logo and distinctive shape, the product acts as an integral marketing strategy to glamorize an item in order to attract the consumer's attention. A smooth part is added on its PTH line to reduce the roughness of through hole
4. The product is designed to be user-friendly both for right- and left-hand users. It is perfectly ideal for businessmen, designers, and professional artists of all ages. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density


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.
