multilayer pcb manufacturing

multilayer pcb (Printed Circuit Board) refers to a type of PCB that consists of multiple layers of conductive traces and insulating material stacked together. Unlike single-layer or double-layer PCBs, which have only one or two layers of conductive materi

Heavy Copper PCB

Heavy Copper PCB manufacturing

Heavy Copper PCB refers to a type of printed circuit board that features a significantly thicker copper layer compared to standard PCBs. The copper thickness in heavy copper PCBs typically ranges from 3 ounces (105 micrometers) to 20 ounces (700 micromete

Steps of the PCB manufacturing process

PCB production process mainly includes design, graphic conversion, plate making, etching, drilling, coating, welding, testing and cleaning steps.

Design phase
The design stage is the starting point of PCB production, and the circuit schematic and PCB layout are designed through CAD software to determine the size of the PCB board, the routing method, the size of the pad and other information.
Graphic conversion phase
After the design is completed, the circuit schematics and PCB layout diagrams need to be converted into Gerber files for processes such as plate making and etching.
Plate making stage
Plate making is the core link in PCB production, by converting the Gerber file into a photoresist film, and then through exposure, development and other processes to transfer the photoresist film graphics to the copper foil, to make the PCB board line and graphics.
Etching stage
Etching is the process of removing the unnecessary copper foil part, by soaking the copper foil after plate making in the etching agent, waiting for a certain time, the excess copper foil is etched away, forming the PCB circuit and graphics.
Drilling stage
Drilling refers to drilling a variety of holes on the PCB board, including pad holes, positioning holes, installation holes, and so on. Drilling requires the use of a drill press or drill machine to operate.
Coating stage
Coating is to remove the photoresist film on the copper-clad plate, and then cover a layer of welding film through the process of drying, exposure, etc., in order to carry out subsequent welding operations.
Welding phase
Welding is the process of installing components to the PCB board and welding them. Soldering iron or welding equipment is required during the welding process.
Detection phase
Inspection is the process of quality inspection of welded PCB board, mainly including AOI inspection, X-ray inspection, ICT inspection and so on.
Cleaning phase
Cleaning is the process of cleaning the welded PCB board for subsequent packaging and assembly operations.
