Company Advantages
1. immersion tin pcb is manufactured by the cutting edge of world technology. It totally conforms to the UL Flame Rating of 94V-0
2. A-TECH CIRCUITS Co., Ltd. has ability to solve and improve all possible problems for its immersion tin pcb . Its solderable surface is protected from the oxidation
3. The quality of the product has been recognized by the international authority. It can reduce the electrical signal loss and provides the highest efficiency
4. The material of immersion tin pcb enhances its performance and enhance its market competitiveness. A smooth part is added on its PTH line to reduce the roughness of through hole


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.
