Company Advantages
1. In order to achieve better water purification effect, A-TECH single layer pcb is carefully developed. The R&D members gradually optimize the filter systems, including pre-filters, mid-filters, and post-filters. The product has the performance of great stability
2. Abundant talent reserves and superior design capabilities for PCB prototype manufacturer are the primary force of A-TECH CIRCUITS Co., Ltd.'s rapid development. It has increased power densities which guarantee its long service life
3. This product will not accumulate odor. It is made of antimicrobial fabric that inhibits the growth of unpleasant odors by controlling bacterial growth. The product has dynamic and mechanical stability

HDI PCB, the full name is High Density Interconnect PCB, it requires much higher wiring density with finer trace and spacing, smaller vias and higher connection pad density. Blind and buried vias’ design is one of their marked feature. HDI PCB are widely used for Cell phone, tablet computer, digital camera, GPS, LCD module and other different area.

The benefits of HDI PCB

● Reduce the cost
● Better reliability
● Increase the wiring density
● Increase design efficiency
● Can improve the thermal properties
● In favor of the use of advanced packaging technology
● Has better electrical performance and signal correctness
● Can improve the radio frequency interference, electromagnetic interference and electrostatic discharge

A-TECH CIRCUITS provides HDI PCB manufacturing services to worldwide customers in the high end automotive industry, medical electronic device industry, mobile, computing and defense industry.

Currently the advanced HDI technology we used include: "Direct Laser Drill"(DLD) is drilling of copper layer by direct CO2 laser irradiation, compare to additional laser drilling with conformal mask, the copper direct laser drilling is capable of providing higher accuracy, better hole quality and better efficiency for HDI projects. "Copper Filled" for special stack microvia, "Laser Direct Imaging"(LDI) is specifically designed for fine line technology, to eliminate dimensional stability problem of artwork caused by environmental and material issues.
