factors affecting PCB assembly costs

PCB assembly involves soldering and mounting components onto a printed circuit board. Methods to lower costs include single-sided mounting, clear labeling, panelization, minimizing board size, reasonable component placement, avoiding placing smaller SMT parts next to larger ones, and minimizing through-hole part usage. Factors affecting assembly costs include the number of layers, size and shape of the circuit board, hole size and quantity, and complexity. Consideration should be given to reducing PCB production costs by adjusting specifications and content, such as using PCBs with less than 14 layers.
