Your Guide to Process Defect of the Month

If you have a process problem, let NPL Defect of the Month Video database help your team

Over the last couple of years, we created lots of videos, that were featured on the IPC and NPL websites. Here is a list to all of the defects and process guides offered FREE just let us know if you would like a copy of all of the links bob@bobwillis.co.uk

The video were created to feature on the IPC website, we still have 3 videos in their top ten. Selected videos have also been featured in Global SMT, Circuits Assembly and Electronics Industry Update magazines and NPL websites and are a guide to may different PCB process issues. Hopefully they may help engineers with assembly faults or could be used in educational events
