The equipment required for PCB manufacturing includes: 8 copper electroplating lines, 2 tin electroplating lines, 1 electroless copper line, 1 desmear line, 2 exposure machines, 2 board grinding machines, 2 developing machines, 1 finished board cleaning machine, 1 etching machine, 6 ovens, 10 screen printers, 1 solder mask mixing machine, 1 squeegee grinding machine, 1 laminating machine, 4 CNC drilling machines, 4 CNC routing machines, and 2 board shearing machines. These machines play key roles in PCB production, but many smaller pieces of equipment are not listed, such as vacuum packaging machines. Gold plating and silver plating can be outsourced according to specific needs.
The copper electroplating line is a key system for depositing copper onto the copper foil. The tin electroplating line deposits tin onto the copper surface to improve solderability. The electroless copper line deposits a conductive copper layer on the PCB surface to form circuit paths. Exposure machines transfer circuit patterns onto photosensitive material. Board grinding machines remove excess copper foil, while developing machines remove unexposed areas. The finished board cleaning machine cleans PCBs to remove residual chemicals. The etching machine removes unwanted copper to define the conductive traces. Ovens cure and dry chemicals on the PCB. Screen printers transfer circuit patterns onto the board. The solder mask mixing machine mixes solder mask ink so it can adhere evenly. The squeegee grinding machine removes excess solder mask. The laminating machine applies photosensitive film to the PCB. CNC drilling and routing machines create holes and cut board outlines. Shearing machines cut panels to required sizes.
In addition to the equipment above, PCB manufacturing may also require smaller supporting devices such as vacuum packaging machines. Gold plating and silver plating are often outsourced. Proper operation and maintenance of these machines are essential for ensuring PCB quality.
For non-standard mechanical parts used across these production lines-such as plating racks, conveyor rollers, exposure machine frames, or custom fixtures for drilling and routing-Hansheng Automation provides precision machining services based on customer drawings and material requirements, helping PCB manufacturers maintain stable production and reduce downtime caused by mechanical wear.
