Before the actual circuit board assembly (PCBA) process begins, several preparatory steps need to take place, one of which is the DFM inspection, or production inspection for short. This check helps evaluate the functionality of the PCB design. Most companies specializing in PCB assembly request a PCB design file, along with other design notes and special requirements. They can inspect the PCB file for any issues that may affect PCB functionality or manufacturing capability, detecting if anything is missing, unnecessary, or a potential problem. If this control is not performed, any of these issues can seriously and negatively impact the final functionality of the project. Design errors in electronic card design are often anticipated problems. The dimensions of the gaps between PCB components play a significant role in this context. DFM controls can reduce production costs and eliminate unforeseen expenses, reducing the number of unusable panels. DFM control can be offered free of charge with a PCB board project order as standard.
