Customer Challenges & Our Solutions

High failure rates in complex multi-layer boards

We mitigate integration risks by offering high-precision manufacturing up to 50 layers with a 0.50% flatness tolerance. By utilizing premium materials like Hi-Tg and Halogen-free FR-4, we ensure structural integrity and thermal stability, reducing the risk of delamination in demanding environments.

Inconsistent signal integrity in high-speed PCB

Our engineering team provides strict impedance control within ±10% to maintain signal consistency. Combined with our capability for 2.5 mil trace/space and various finishes like ENIG or Immersion Silver, we provide the technical precision necessary for high-frequency applications.

FAQ

What is your capability for minimum hole size and spacing?

We achieve a minimum finished hole size of 0.15 mm and a minimum trace/space of 2.5/2.5 mil for outer layers. This high-density capability allows for more compact designs and complex routing required in modern multi-layer board configurations.

Can you handle non-standard PCB thicknesses and materials?

 Yes, our factory supports finished board thicknesses from 0.3 mm to 5.0 mm. We work with a wide array of base materials including Ceramic, Teflon, Polyimide, and Metal cores to meet specific thermal or mechanical requirements.

Do you offer surface finishes for lead-free requirements?

We provide several lead-free compliant finishes, including lead-free HASL, ENIG, Immersion Silver, and OSP. These options ensure your multi-layer board meets international environmental standards while maintaining excellent solderability and shelf life.
