Buying and ordering printed circuit board manufacturing
PCB manufacturing process
PCB fabrication is the process or method that converts the circuit board design into a physical structure based on the specifications provided in the design package. This physical manifestation is achieved through the following actions or techniques:
• Imaging of desired layout on copper coated laminates
• Etching or removing excess copper from internal layers to expose traces and pads
• Creating a stack of PCB layers by laminating (heating and pressing) board materials at high temperatures
• Holes for mounting holes, through hole pins and vents
• Etching or removing excess copper from surface layer(s) to expose traces and pads
• Plating of pin holes and through holes
• Adding a protective coating to the surface coating or solder
• Silk-print reference and polarity markers, logos or other markings on the surface
• If desired, a coating may be added to the surface copper areas
Now let’s see what this information means for PCB development.
Is it important to understand the PCB manufacturing process?
The question can and probably should be asked: “Is it important to understand the PCB manufacturing process?” After all, PCB manufacturing is not a design activity, it is an outsourced activity performed by a contract manufacturer (CM). While it is true that fabrication is not a design job, it is done by strictly following the specifications that you provide to your CM.
