Company Advantages
1. osp pcb finish material provides carbon pcb with long service life. The product is certified under UL(E357001) and RoHS
2. The product has been more popular than before and gained more and more customers. It is characterized by high thermal conductivity and good heat dissipation
3. The product features accurate specifications. It usually has tight tolerances in order to match up to other parts or assembly. The product has the performance of great stability
4. The thickness of the lines is determined by the writing pressure of this product. The greater the pressure, the more liquid crystals are twisted and the thicker the lines are. With a solder mask, it enjoys a good electrical insulation property
5. The dehydrating process will not cause any Vitamin or nutrition loss, in addition, the dehydration will make the food richer in nutrition and enzymes concentration. The product has dynamic and mechanical stability


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.
