Product Details
A-TECH strives excellent quality by attaching great importance to details in the production of Multilayer PCB.
Application Scope
Aluminum PCB has a wide range of applications. It is mainly used in the following industries and fields.A-TECH always adheres to the service concept to meet customers' needs. We are committed to providing customers with one-stop solutions that are timely, efficient and economical.
Company Advantages
1. A-TECH pcb gold plating is manufactured by adopting environmentally-friendly concepts. The wood materials are sustainably sourced and strictly tested to be non-toxic.
2. The product is scratch and wear resistance. Its materials are all abrasion-proof and have excellent chemical and physical strength and stiffness.
3. Containing no odor, the product is especially preferable for those who are sensitive or allergy to furniture odor or smell.


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.
