Hitech Circuits Co., Limited have been specializing in quick turn PCB prototype & small up to middle volume Rigid PCB more than 10 years, we are not only produce double sided board, multi-layer PCB prototype, small and medium-volume multi-layer PCB is also no problem. We can make up to 38 Multilayer PCB, Min. Hole Size 6mil, Min. line width/space 4mil with quick turn manufacturing service.
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. This process and the resultantboardsallow interconnections between layers through all holes. And meanwhile, most designs require soldermask front and back along with a silkscreen layer for component designators.
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.
The following are examples of double sided pcb application.
