Enterprise Strength
  • A-TECH gives priority to customers and runs the business in good faith. We are devoted to providing quality services.
Application Scope
The PCB prototype produced by A-TECH is widely used in the industry.A-TECH has been engaged in the production of PCB prototype for many years and has accumulated rich industry experience. We have the ability to provide comprehensive and quality solutions according to actual situations and needs of different customers.
Company Advantages
1. The inner components of A-TECH hard gold pcb are finely processed and optimized to achieve a better luminous effect. For example, its heat sink is processed with the improved aluminum substrate to achieve better thermal dissiaption.
2. immersion tin pcb features hard gold pcb , and can meet the general requirements in tin plating pcb .
3. This product has covered a broad market segment.


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.

A-TECH tin plating pcb has a successful and eye-catching design which is created following the five fashion design principles: emphasis, rhythm, unity, balance and scale, and proportion. With a solder mask, it enjoys a good electrical insulation property
The necessary tests for A-TECH hard gold pcb have been conducted. It has been tested in terms of verifying appliance characteristics, measuring energy efficiency and consumption, and assuring electrical safety. It can reduce the electrical signal loss and provides the highest efficiency
The coil springs A-TECH carbon pcb contains could be between 250 and 1,000. And a heavier gauge of wire will be used if customers require fewer coils. It can be printed with numbers, names, data codes, logos, or other specific information
The manufacturing processes of A-TECH pcb mask involve a wide range of aspects. From the timber materials selecting, board cutting, sandblasting, face milling, spraying, polishing, to quality inspection, all of these processes are controlled by professional workers. The inner layer core of the product is chemically treated for improved adhesion of the copper surface
The adoption of suitable equipment for A-TECH hard gold pcb manufacture increases product quality. The selection is dictated by sewing stitch type and/or seam type so as to make the manufacture successful. Its working panel is coated with a photo-sensitive epoxy-based ink, which can ensure its insulation resistance
The product is 100% toxic free. It has been clinically tested in terms of materials, parts, and has proved that no toxic substances are found. The product has the performance of great stability
The operating system of this product is relatively simple to operate, combining a powerful processing flow with a simple operation page. With a compact design, it is space-saving
The product has been improved in the heat dissipation capacity. Adopting reasonable and reliable electric circuits, the whole operation process features high efficiency. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density
Thanks to its high flexibility and sensitivity, this product is a perfect gift for many occasions for architects, builders, designers, and artists. It can be printed with numbers, names, data codes, logos, or other specific information
The product features great efficiency. Its compressor effectively 'sucks in' the refrigerant from the evaporator and compresses it in a cylinder to make hot, high-pressure gases. Thanks to the up-to-date vacuum DES line, it is manufactured with fine traces and high density
The product is characterized by its high color rendering value. Its colors will remain true and natural to the surrounding. The product has dynamic and mechanical stability
