PCB Coatings

PCB coatings are designed to deposit coatings such as printed circuit board (PCB, PWB), flexible circuits, silicon wafers, semiconductors or IC chips, IC packages, and reel-to-reel connectors or lead frames. For example, the equipment may apply a dielectric conformal coating to insulate and protect the PCB or flexible circuit. Other PCB coating equipment can selectively apply conductive metal pastes or solders to form circuitry or aid in forming soldered connections. Thick film and thin film circuits are also formed using coating techniques. Spin coaters are typically used to apply photoresist. Dopants (SOG type) and dielectric layers are also applied to wafers using spin coating techniques. Other PCB coating equipment can selectively apply conductive metal pastes or solders to form circuitry or aid in forming soldered connections. Wafer level metallization and thin film circuits or interconnect are also formed using PVD, CVD and ECD coating techniques.
