Application Scope
PCB prototype's application range is specifically as follows.A-TECH has an excellent team consisting of talents in R&D, production and management. We could provide practical solutions according to actual needs of different customers.
Company Advantages
1. A-TECH hasl pcb finish is manufactured by skillful professionals using top class techniques and modernized machines.
2. This product is weatherproof. Materials that can withstand damage from harsh UV rays and fluctuations from extreme heat to cold are used.
3. A-TECH CIRCUITS Co., Ltd. adheres to customer-oriented quality management strategy.


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.

A-TECH hasl pcb finish is produced under strict scrutinization. It is checked for its material ingredients as well as material extraction methods to guarantee its quality. Screen printing and embossing can be applied to the product
The production of A-TECH hasl pcb finish 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. The product undergoes the pickling and passivation process to have a glossy surface
High-tech processing equipment is used in the production of A-TECH hasl pcb finish. It is done under the detritus equipment, grinding equipment, as well as sand-making equipment, which can guarantee high purity and fineness. It can keep beer fresh for weeks as it completely isolates negative factors from the beer
The raw materials of A-TECH hasl pcb finish are treated with several procedures. Materials enrichment, refining, and smelt process will be conducted to make the materials into a product with high purity. The product is 100% UV resistant and static electricity resistant
A-TECH hasl 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]
The product is superior in quality and reliable in performance. Its handhole is well deburred for improved safety
