Product Details
A-TECH's PCB prototype has excellent performances by virtue of the following excellent details.
Enterprise Strength
  • A-TECH insists on providing sincere services to seek common development with customers.
Company Advantages
1. enig pcb is made by immersion silver pcb finish which provides a number of advantages.
2. This product is wonderfully creative and efficient. Unlike the old outdated office accessories, the product adds great charm to the office.
3. This product fills demand gaps in the industry.


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 enig pcb is produced under strict scrutinization. It is checked for its material ingredients as well as material extraction methods to guarantee its quality. It helps keep constant temperature which will not ruin beer flavour
The production of A-TECH enig pcb covers a few steps. The rough concentrate is deeply processed at first to extract some useful ingredients, then the concentrate is further ground for higher purity. It can keep beer fresh for weeks as it completely isolates negative factors from the beer
High-tech processing equipment is used in the production of A-TECH enig pcb. It is done under the detritus equipment, grinding equipment, as well as sand-making equipment, which can guarantee high purity and fineness. The product will not influence the taste of beer by creating a confined space
The raw materials of A-TECH enig pcb are treated with several procedures. Materials enrichment, refining, and smelt process will be conducted to make the materials into a product with high purity. Its neck is sealed through double TIG welding, ensuring excellent airtightness
A-TECH immersion silver pcb finish will go through several manufacturing stages. First, the raw materials will be crushed and ground, then they are separated and concentrated to separate the waste ingredients out. 卖点、特色句]
