Company Advantages
1. A-TECH carbon ink pcb is made from raw materials with good properties and strong durability. It has increased power densities which guarantee its long service life
2. As a professional and experienced brand, it is important for A-TECH to attach great importance to the quality of carbon ink pcb . Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density
3. The product is valued for its fire resistance. The flame retardants have been added to reduce the possibility of getting fired. The inner layer core of the product is chemically treated for improved adhesion of the copper surface
4. The product is tear resistant. Made of highly durable materials that are tightly woven, it can effectively resist puncturing. 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.
