♦ What Is SMT Assembly?
SMT Assembly (Surface-Mount Technology Assembly) is the core process in mobile-phone PCB production where every tiny chip, resistor, capacitor, connector, etc. is placed and soldered onto the bare board without through-holes. In short, it turns the etched copper substrate into a functional circuit.
♦ What Is DIP Assembly?
DIP Assembly (Dual In-line Package Assembly) is the through-hole step that comes after SMT in mobile-phone PCB production. Components whose leads are too large, need high mechanical strength, or carry high current (e.g., big connectors, shielding frames, some inductors, early-stage camera modules, or legacy ICs) are inserted into pre-drilled holes and then wave-soldered or hand-soldered to the board.
