Company Advantages
1. A-TECH has a unique design. Our designers experiment with various materials, often mixing textures, textiles or even incorporating multimedia elements into its design. It is extremely popular in the markets of Europe, North America, and Asia
2. Instead of causing radiation that is harmful to health, the product can help people lower the risk of illnesses such as headache. It can be printed with numbers, names, data codes, logos, or other specific information
3. Through strict quality monitoring process, all relevant defects of the product have been reliably detected and removed. 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.




Company Features

3. We will become representative of the industry's innovation and creation. We will invest more in cultivating our R&D team, continuously promote technological innovation, and learn from other strong competitors to enhance ourselves.
A-TECH define solder must go through these following production stages, including metal materials procurement and preparation, components machining, surface polishing, and assembly. Containing no harmful glue, it is safe to use
A-TECH define solder has been tested according to the general standards. It is tested in terms of functionality, strength, stiffness, wears, and corrosion. The product can offer certain buffering from the impact
A list of factors is taken into account of A-TECH define solder conception. They involve complexity, feasibility, optimization, tests, etc. of a machine. Its rolling end face is very smooth and neat
Lots of factors are taken into consideration in A-TECH hasl rohs design. They are required motion, required space, speed of operation, required labor, etc. It has been widely exported to Taiwan, the USA, Europe, Southeast Asia, and the Middle East
There are many factors being considered during A-TECH define solder design. They include the selection of material, form and size of the parts, frictional resistance and lubrication, and safety of the operator. It will bond instantly as soon as people apply it and add pressure to it, saving the time waiting for the adhesive to cure
It has the proper size in consideration of the force. Each element of this product is designed with the most suitable size by considering the force acting on it and the permissible stresses for the material used. It produces no strident squeak when used
