Prototype PCB Manufacturing Process – A Step by Step Guide
The complete Prototype PCB manufacturing process is based on the design package that makes the circuit board in physical form. Step 1: Pre-Production Engineering According to the manufacturing data and requirements provided by the customer, our engineers will compare it with standards and capabilities to ensure compliance and conduct related checks. Step 2: Photo Plotting A laser photo-plotter can be used to plot a film for each individual layer. A laser photo-plotter is a tool used to create photo tools for solder masks and silkscreen. Step 3: Imaging and Develop or Etch This process applies the primary images such as pads and traces onto the circuit board. Here is what to do in this step: Apply the photo image to the copper panels. Furthermore, image the panels using LSI. Etch off the whole exposed copper from the panel. Strip the remaining Dry Film and just leave the remaining copper pattern for the inner layers. Step 4: Automated Optical Inspection AOI basically inspects differen
