Improving PCB Assembly Quality with Visual Inspection

Are you facing challenges with parts not fully covered by paste during PCB assembly? Don’t worry, you’re not alone. It can be tricky, especially with tiny 0402 parts scattered around the board.

So, how do you ensure proper coverage and avoid such issues in the future? One effective solution is to conduct a visual inspection before and after stencil work.

• Take a picture of the PCB before applying paste.
• Apply paste on the PCB.
• Take another picture after the paste application.
• Compare the two images to identify any discrepancies.

This simple yet effective method can help you spot any missed areas and improve the overall quality of your PCB assembly process. By visually comparing the samples before and after stencil work, you can ensure that all parts are properly covered, reducing the risk of errors and improving the overall reliability of your PCBs.

By incorporating visual inspections into your assembly process, you can enhance quality control and streamline your production workflow. So, next time you encounter issues with paste coverage, consider implementing this visual inspection technique for better results.
