Company Advantages
1. The production of A-TECH peelable solder mask pcb is in compliance with the accepted international standards. Being laminated by advanced vacuum lamination equipment, it has a uniform dielectric thickness after lamination
2. The product helps clean the dirt under the pool or any particles on the shore of the pool, which can reduce the risk of slipping. It has increased power densities which guarantee its long service life
3. immersion gold pcb has the good virtues of peelable solder mask pcb , and all proved that it is a optimal hasl pcb finish . It is vacuum-sealed, which can greatly reduce the bulk of the overall cargo
4. With technology innovation, such features as peelable solder mask pcb make immersion gold pcb warm welcomed by costumers. With a compact design, it is space-saving
5. immersion gold pcb offers several advantages in terms of peelable solder mask pcb . It can be printed with numbers, names, data codes, logos, or other specific information


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.
