Company Advantages
1. The packaging quality is important for A-TECH carbon pcb . Its packaging materials comply with EU packaging materials and waste directive for the battery. It stands out for its impact endurance performance
2. A-TECH CIRCUITS Co., Ltd. has abundant material resources for carbon pcb . It can be manufactured with a customized thickness
3. This product effectively resists pilling. The structure of the fabric is totally tightened and the frictional resistance is relatively enhanced. With a solder mask, it enjoys a good electrical insulation property
4. The pen for this product includes a pressure detection system. As with a pencil, applying more pressure leaves a darker line, while less pressure makes a lighter one. With a compact design, it is space-saving
5. The product is highly chemical resistant. It is treated with a protective chemical coating or with protective paintwork to prevent corrosion. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance

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.
