Company Advantages
1. A-TECH has been tested according to the general standards. It is tested in terms of functionality, strength, stiffness, wears, and corrosion. It is extremely popular in the markets of Europe, North America, and Asia
2. The long life of the product eliminates the need to change the lamp frequently, which is especially helpful for people living in remote areas. It is widely used in different electronics industries, such as telecommunication and consumer electronics
3. The product is not subject to deformation under high temperature. The steel material used in it contains a high content of chromium and nickel which have excellent creeping strength, hence, it is heat-resisting. The product has dynamic and mechanical stability
4. The product is safe enough. Its housing performs well in preventing water or moisture from entering into the inner part, posing no electric shock hazard. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density

HAL(Lead Free), the full name is Hot Air leveling with Lead Free. Compared with HASL, the main difference for HAL(Lead Free) is the element of material which do not contain Lead(Pb), so it’s RoHS Compliant and it’s much more popular and widely used in PCB manufacturing.

HAL(Lead Free) requires higher run temperatures for lead free solder and longer contact time, the production cost for HAL(Lead Free) is slightly higher than HASL(Tin/Lead).

The manufacturing process of HAL(Lead Free) is similar to HASL(Tin/Lead), the circuit boards will be submersed in molten solder(Lead Free). 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.

The typical thickness of HAL(Lead Free) is 1-40um and the shelf life is 12 months.

The advantages of HAL(Lead Free) surface finish

● Good solderability / wettability
● RoHS Compliant
● Good reflow properties
● Large processing window is allowed
● Multiple thermal excursions
● Can be widely used

The disadvantages of HAL(Lead Free) surface finish

● Uneven surface
● Not suitable for PCBs with fine pitch
● Thermal shock
● Solder bridge
● Plugged or Reduced plated through holes

A-TECH have HAL(Lead Free) surface finish in house, It’s basically the highest proportion of finish used for circuit boards without fine pitch or high density layout. We don’t have any additional cost for HAL(Lead Free) surface finish.
