    Start with prototype quantities and continue with us to ramp up production level quantities

    We are one-stop printed circuit board manufacturer , providing PCB fabrication services for single, double or multi-layer PCBs in low volume and high-volume production amounts with a wide range of materials and technology options.

     Leveraging our design and assembly services in a turnkey production system, we can provide low-cost PCB manufacturing with the highest quality. Using a variety of inspection methodologies to ensure the functionality of the final product. We offer Full Spec, small quantity printed circuit boards and Custom Spec quick turn PCBs. In addition, we are the premier provider of printed circuit boards to the Military/Aerospace/Defense/Medical and Commercial Industries.  


    Benefits of Multilayer PCBs (compared to single or double-sided PCBs)

    • Higher assembly density 
    • Smaller size (considerable savings on space) 
    • Increased flexibility 
    • Easier incorporation controlled impedance features. 
    • EMI shielding through careful placement of power and ground layers.


    Application of Multilayer PCB

    Much of the favoritism toward multilayer PCBs lies in industry trends. With electronics progressing ever toward miniaturization yet multi-functional options, the internal components of those electronics must follow the same trend. While single and double-sided PCBs have proven limited in their ability to balance size and functionality, multilayer PCBs provide a comprehensive solution.

    Testing Procedures

    We perform multiple quality assurance procedures before shipping out any PCB board. These include:

    • Visual Inspection
    • Flying probe
    • Bed of nails
    • Impedance control
    • Solder-ability detection
    • Digital metallograghic microscope
    • AOI (Automated Optical Inspection)

    Quick turn lead times

    For Multilayer PCB Mass Production, we can provide regular 7-10 days turn around times.  And the fastest turnaround time depends on the number of layers and quantity.
