Double sided PCB & Double printed circuit PCB

Double-sided PCBs(Double-sided Printed Circuit Boards)are one step up above single-sided printed circuit boardin their complexity.

Double Sided PCBs require plated through holes between top and bottom pads to provide better anchoring for soldered components. Today the double sided printed circuit board technology remains the workhorse of the assembly industry. There are near limitless applications for old and new designs. Fine line surface mount, ultra high copper build, high and low temperature, Solder coated, Silver, and Gold finishes are just a few examples of double sided board applications.

Hitech Circuits Co., Limited engage in providing the best quality, service and the competitive cost for our customers. If you need more information aboutprinted circuit boards (PCBs), please don't hesitate to contact us.
