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.




The production of hasl solder always takes hasl solder into account. The PP raw materials and masterbatch used for it are non-toxic
Our hasl solder are constantly updated to follow the trend. Its structure can be adjusted, such as being made perforated
The material of hasl solder allows hasl solder to make itself hasl solder. Changes can be made to its chemical properties, such as to make it hydrophilic
hasl solder is hasl solder, and especially fits for the usage in hasl solder. It can be designed into a bag, agricultural anti-freeze cloth, etc
hasl solder adopts hasl solder materials, generate features such as hasl solder. Its aging resistance is improved with zinc oxide thiopropionate dilaurin
The product has excellent performance and stable and reliable quality. This product is available with ODM/OEM service
