Company Advantages
1. A-TECH enig pcb finish is manufactured utilizing premium materials sourced from the certified vendors. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance
2. Our hasl pcb will go through multiple processes to make quality guaranteed before loading. It stands out for its impact endurance performance
3. Strict quality inspections are carried out before delivery to increase its qualification ratio. With a compact design, it is space-saving


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.




Company Features
1. Nothing is more important than quality of hasl pcb in A-TECH CIRCUITS Co., Ltd..
2. enig pcb finish is a permanent tenet of A-TECH CIRCUITS Co., Ltd. to improve himself. Inquire online!
Our design for hasl pcb is very fashionable and special. There is no residual glue after stripped off
The body framework of hasl pcb using hasl pcb concept has more advantages. The product does not peel off even used in a humid environment
In addition, A-TECH applies selected enig pcb finish as well as elaborated-designed enig pcb finish to develop our products. The product is water- and moisture-resistant
enig pcb finish is featured by its enig pcb finish. It will bond instantly as soon as people apply it and add pressure to it, saving the time waiting for the adhesive to cure
The structure of enig pcb finish is also one of the highlights of the product. The product is available in many different sizes and viscosity levels
The product features strong tensile strength. The elongation and fracture point of the part has been tested at a constant rate while measuring the load. It will not lose its adherence force even stored for a long period
