assembly labor and components with real time pricing available through the online quote system for a detailed cost breakdown and pricing examples check our full guide pcb assembly price details how do i prepare a bom file for pcb assembly make sure your bom includes component values reference designators package types and manufacturer part numbers standard formats like csv xls or xlsx are recommended view detailed instructions and a sample bom file here complete bom guide how can panelization reduce pcb assembly costs panelization groups multiple pcbs into one panel so they can be assembled simultaneously improving efficiency and lowering cost per unit for better efficiency and pricing panelization is strongly recommended for quantities over 50 pcs see detailed pcb panel guidelines how long does pcb assembly take pcb assembly begins immediately after pcb fabrication is completed since all necessary materials such as components engineering data and solder paste stencils are prepared in advance there is no delay between stages about 90 of pcb assembly orders are completed within 24 hours and most within 48 hours at most this makes it ideal for rapid prototyping and urgent production needs learn more about lead times and production details here smt service lead time guide what if i can t find a component in the jlcpcb parts library components for
