Single-sided PCB traces are present on only one side, while double-sided PCBs have traces on both sides with top and bottom layers. The components and conductive copper are mounted on both sides of a double-sided PCB, and this leads to the intersection or overlap of the trace.
Free QuoteSMT, or Surface Mount Technology, is a method for assembling electronic circuits by mounting electronic components directly onto the surface of a printed circuit board (PCB). This technique has largely replaced the older through-hole technology due to its advantages in miniaturization, cost reduction, and automated manufacturing.
