Company Advantages
1. A-TECH osp coating pcb can be assessed in accordance with regulations in the target market. It will be scrutinized in terms of flammability, the safety level of fabric ingredients, and the safety of dyestuff to meet requirements of clients' markets. It has low water absorptivity in the damp environment
2. [企业简称] has professional design team and production team. Besides, we have advanced production technology and sophisticated production equipment. All this provides a strong guarantee for the high quality of immersion silver pcb .
3. The properties of immersion silver pcb can fully meet up with user's requirements, such as osp coating pcb . Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density
4. Customers are greatly satisfied with the function of the product. It stands out for its impact endurance performance
5. The product is subjected to extensive quality assurance and testing program before shipment. It has high tensile strength and can be deformed without breakage


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.
