    1. ENIG PCB

      Comparing to HASL and Immersion Silver, this PCB surface finish has been extensively applied to high-end PCB. The process of Electroless Nickel plating and immersion gold has been approved to be lead-free. Its ultra-flat surface provides stable welding spots and resistance to exterior environment and touching, etc.

    1. IAg PCBThis kind of PCB surface finish is perfect for circuit in high density. Both interior and exterior copper thickness is 35um. PCB thickness is 1.8mm. Material option is FR-4. This PCB is often seen in military products.
    1. OSP PCBThis rigid PCB is 1.0mm thick and receives RoHS compliant surface treatment. Moreover, we apply vacuum packaging method to all incoming materials and finished OSP PCBs. Separating paper is placed among all boards to prevent surfaces from friction damage.
    1. Single Sided PCBOur single sided PCB is available in CEM, FR-4, aluminum-based and copper-based metal materials. This kind of single layer PCB has been extensively applied to LED lighting fixture industry and high power military products.
    1. Double Sided PCB

      Half hole is drilled with brand new drilling tool after electroplating treatment to achieve burr-free and clean finish. 3uin thick gold ensures the best soldering. Copper thickness is 35/35um and half hole size is 0.4mm. This double sided copper clad is well-suited for signal conversion.

    1. Rigid-flex PCBWe excel at providing rigid-flex PCB in small and medium production volume. Our rigid flex board is available in 20 layers. The minimized trace width only reaches 3mil. Moreover, we are also nimble in PCB fabrication of HDI and impedance controlled rigid-flex PCB.
    1. Aluminum Based PCB

      Our aluminum based PCB is available as aluminum PCB for street light, fluorescent lamp and spot light as well as high power aluminum core board. One sided aluminum layer PCB is emerged as alternative to FR-4 and PCB fiberglass panel, for this PCB substrate shows more excellence in terms of rigidity, cooling efficiency and toughness.
