What is PCB tombstoning? PCB tombstoning, also known as chip lifting or Manhattan effect, is a defect that occurs during the reflow soldering process of surface mount components on printed circuit boards (PCBs). It is characterized by one end of a component lifting off the pad, while the other end Read more…
What are PCB pads? PCB pads, also known as solder pads or landing pads, are conductive areas on a printed circuit board where electronic components are soldered. These pads provide a surface for the component leads or pins to be attached, enabling electrical connectivity between the component and the PCB Read more…
What are Castellated Pads? Castellated pads, also known as castellated holes or castellations, are a type of surface mount technology (SMT) used in printed circuit board (PCB) design. These pads are essentially plated through-holes (PTHs) that are cut in half along the edge of the PCB, creating a series of Read more…
