Manufacturing Process of Volume Circuit Boards
Designing the Circuit Board
The first step in manufacturing a volume circuit board is designing the circuit board. This involves creating a layout of the circuit board using computer-aided design (CAD) software. The layout includes the placement of components, routing of traces, and the location of holes for mounting. The design must be optimized for manufacturability, functionality, and cost-effectiveness.
Printing the Circuit Board
Once the design is complete, the next step is to print the circuit board using a specialized printer. The printer uses inkjet or laser technology to print the circuit design onto a copper-clad board. The ink or toner used in the printing process is resistant to the chemicals used in the etching process.
Etching the Circuit Board
After printing, the board is etched to remove the unwanted copper. The board is immersed in a solution of ferric chloride or ammonium persulfate, which dissolves the copper that is not protected by the ink or toner. This leaves behind the traces and pads that make up the circuit.
Drilling and Plating the Holes
Next, the holes for mounting the components are drilled into the circuit board. The holes are then plated with a thin layer of copper to improve conductivity and prevent corrosion. This process is called electroplating.
Solder Masking
After the holes are plated, the board is coated with a layer of solder mask. The solder mask protects the traces and pads from accidental soldering and prevents short circuits. The solder mask is applied using a screen-printing process.
Silk Screening
Finally, the board is silk-screened with labels and markings to identify the components and their locations. The silk-screening process uses a stencil to apply ink to the board.
