Enterprise Strength
  • A-TECH is committed to providing the best products and services for customers.
Product Details
Next, A-TECH will present you with the specific details of PCB Assembly.Under the guidance of market, A-TECH constantly strives for innovation. PCB Assembly has reliable quality, stable performance, good design, and great practicality.
Company Advantages
1. The raw materials of A-TECH pcb gold plating are well prepared and are efficiently used in the production.
2. This product is regarded as a leader in low electromagnetic emission. It does not tend to affect the normal operation of the peripheral electrical devices by causing a strong electromagnetic field.
3. The product has fine air and water permeability. The surface is treated with a coating film which can change the hygroscopicity of the product.
4. The product is priced low and has a broad market application prospect.
5. It is widely accepted that the product has a prospective market application.


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.
