Introduction to BGA Soldering Ball Grid Array (BGA) is a surface-mount packaging used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package. The whole bottom surface of […]

What are Gold Finger PCBs? Gold finger PCBs, also known as edge connector PCBs or contact fingers, are printed circuit boards with gold-plated contact pads along one edge. These gold fingers allow the PCB to be plugged into a socket or slot for easy connection and disconnection. The gold plating […]

What are Arduino Shields? Arduino shields are expansion boards that can be connected to an Arduino board to add specific features or functionalities. They are designed to be plugged directly on top of the Arduino board, using the same pin layout and form factor. This allows for easy integration and […]

What is PCB Warpage? PCB warpage refers to the deviation of a PCB from its intended flat shape. It is a type of dimensional instability that occurs when the board experiences uneven thermal expansion or contraction during the manufacturing process or under certain environmental conditions. The warpage can be classified […]
