    Many pcb circuit board copy board manufacturers now have complete production lines and service procedures, and independently complete the production and processing of circuit board copy boards according to the designed circuit board copy board files.

    iPcb shares the technological production process that needs to be understood:


    1. Single-board pcb process production flow chart

    Cutting edge grinding → drilling → outer layer graphics → (full board gold plating) → etching → inspection → screen printing and solder resistance → (hot air leveling) → screen printing text → circuit board copy board shape processing → inspection Library → Shipment Management



    2. Double-layer circuit board copy board tin spraying process flow chart

    Cutting edge grinding → drilling → sinking copper → outer layer graphics → thickening of electric copper → tinning, etching, removing tin → inspection → screen printing, solder resistance → gold-plating plug → circuit board copy board hot air leveling → wire Screen printing text→spray tin→pcb shape processing→test→inspection→warehousing→shipment management



    3. Multi-layer circuit board copy board tin spraying process flow chart

    Cutting edge grinding → inner layer pattern → inner layer etching → inspection → blackening → layering → drilling → thickening of copper sinking → outer layer pattern → thickening of electric copper → tinning, etching and removing tin → secondary drilling → Inspection → screen printing and solder mask → gold-plated plug → hot air leveling → screen printing text → spray tin → forming processing → inspection → inspection → warehousing → shipping management



    4. Process flow chart of nickel plating and gold plating for multi-layer circuit boardcopy board

    Cutting edge grinding → drilling positioning holes → inner layer pattern → inner layer etching → inspection → blackening → lamination → drilling → copper sinking → outer layer pattern → electric copper thickening → gold plating, film removal and etching → inspection → screen Printing and solder mask → screen printing text → pcb shape processing → inspection → inspection → warehousing → delivery management


    The above is the process and production process that a few circuit board copy boards need to understand.
