Introduction to Castellated PCBs Castellated PCBs, also known as castellated hole PCBs or castellations, have become increasingly popular in the electronics industry due to their versatility and ease of assembly. These PCBs feature small, semi-circular holes or slots along the edges, resembling the battlements of a castle, hence the name […]

Understanding BGA Packages Before we dive into the reballing process, it’s essential to understand what a BGA package is. A BGA is a type of surface-mount packaging used for integrated circuits (ICs). It consists of a rectangular or square package with a grid of solder balls on the bottom. These […]

What is a BGA chip? A Ball Grid Array (BGA) is a type of surface-mount packaging used for integrated circuits. The bottom of a BGA chip features a grid of solder balls that connect to contact pads on a printed circuit board (PCB). This packaging allows for a high density […]

Introduction to PCB Soldering PCB (Printed Circuit Board) soldering is a crucial process in the manufacturing of electronic devices. It involves the attachment of various components, including chip packages, to the surface of a PCB using solder, a metal alloy that melts at a relatively low temperature. Proper soldering ensures […]
