FR4, often written as FR-4, is a widely recognized and high-performing substrate material used in PCB manufacturing. Its affordability, insulation properties, and structural integrity make it the foundation for most PCB designs. FR4 boards are coated with copper foil using adhesive to create conductive layers, either single or double-sided, depending on the design. This flexibility allows for the development of complex multilayer PCBs, making FR4 the default choice for many applications.
Design for Manufacturability (DFM) optimizes designs for the manufacturing process, making it an essential component of concurrent engineering. By considering factors such as manufacturability and assembly requirements early in the design phase, DFM streamlines production, bridges CAD-CAM communication, and enhances product reliability. Here, we cover general technical requirements for DFM in PCB manufacturing.
In circuit board manufacturing, various electroplating methods are employed to enhance performance, durability, and contact quality. This article focuses on four specialized electroplating methods commonly used in PCB (printed circuit board) welding processes
