What is Countersinking and Counterboring? Countersinking and counterboring are two techniques used to create recesses in a printed circuit board (PCB) to accommodate the heads of screws or other fasteners. These techniques are essential for ensuring that the fasteners sit flush with the surface of the PCB, preventing any protrusion […]

What is Through-hole Assembly? Through-hole assembly, also known as through-hole technology (THT), is a method of mounting electronic components on a printed circuit board (PCB) by inserting component leads through holes drilled in the board and soldering them to pads on the opposite side. This assembly technique has been widely […]

Introduction to Selective Soldering Selective soldering is a process used in printed circuit board (PCB) assembly where specific components are soldered onto the board without affecting nearby components. This technique allows for precise soldering of selected components while leaving heat-sensitive or pre-assembled components intact. Selective soldering offers several advantages over […]

Introduction to Flex and Flex-Rigid PCBs Flexible printed circuit boards (PCBs) and flex-rigid PCBs are versatile interconnect solutions that offer many advantages over traditional rigid PCBs. Flex PCBs consist of a thin insulating polymer film laminated with conductive copper traces. This allows the PCB to bend, fold, and flex, enabling […]
