The latest CD from SMART Group provides inspection criteria for surface mount and conventional assembly and soldering as well as providing a defect guide for common defects found during wave and reflow soldering. Included on the CD is a complete guide to introducing yield monitoring based on Part Per Million PPM or Defects Per Million DPM with a spreadsheet for recording the defects. Video sequences show how to fill in the forms using screen printing as a reference. Animated process guides highlight other process stages for both conventional and SMT where in-process sample inspection should be conducted.
Also included are a range of in process quality control procedures for each stage of the process, which is considered critical as well as visual guidelines for acceptable criteria. These cover screen printing, stencil checks, placement, component loading, reflow, wave soldering, manual assembly and final inspection. These procedures are ideal for any company standard or as a guide to the minimum standards for contracting out assembly. An interactive test is provided to assess your staff's understanding of inspection criteria and normal in process control. Twenty questions are included and the results are saved for each staff member taking the test.
