Product Details
A-TECH's Aluminum PCB is exquisite in details.
Enterprise Strength
  • A-TECH provides excellent service for customers based on the principle of 'customer first'.
Company Advantages
1. Most of A-TECH carbon ink pcb are produced by hand. This process is carried out by our highly qualified employees ensuring absolute precision in this sensitive process of making original molds.
2. Commercially manufactured immersion silver pcb are carbon ink pcb .
3. immersion silver pcb shows advantages in carbon ink pcb , and therefore deserves popularization.
4. It manages light, air, energy, and even information. It can act to reduce the solar gain as well as allowing the passage of fresh air into the building, helping to alter the interior environment.
5. It is more cost-effective. Getting the brand an ad on most media platforms is always pricey, yet it only takes a fraction of the cost to put information on this product.

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.
