Company Advantages
1. In order to be more competitive, our peelable mask pcb are all designed to be unique. It totally conforms to the UL Flame Rating of 94V-0
2. Some of our customers who live in a remote area where electricity is expensive to afford said this product brings much convenience to their life. It can reduce the electrical signal loss and provides the highest efficiency
3. Good environment of production zone and workshop is one of the conditions for improving its quality.
4. This product is ensured to be of high quality under the supervision of a quality team. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance
5. The product is not only reliable and safe but also has the key features of long-lasting performance and good durability. Its robust structure allows it to be used in harsh environments


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.
