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.




There are sufficient considerations regarding A-TECH osp surface finish pcb design. They are Aesthetics (the meaning of form), Principles of Design (unity, harmony, hierarchy, spatial order, etc.), and Function & Social Use (ergonomics, comfort, proxemics).
A series of testing for A-TECH osp surface finish pcb are required out of concern of safety. The testing includes fabric composition testing, safety, and environmental testing.
A-TECH osp surface finish pcb must go through chemical analysis. Chemical substances such as Azo dyes, Formaldehyde, PCP (Pentachlorophenol), Nickel, and Cadmium are strictly analyzed.
osp surface finish pcb Adopting a scientific design, it is not only safe and comfortable to use, but also easy to disassemble and clean.
According to the general painting habits of the public, the company uses the concept of ergonomics to carry out innovative design, designs a practical and beautiful easel, and strives to bring each customer a different comfortable experience.
With technology innovation, such features as osp surface finish pcb make osp surface finish pcb warm welcomed by costumers.
