Second edition of the CD provides a guide to all aspects of wave soldering with all the common process defects. Each stage of the process including fluxing, pre heat, solder wave and conveyors are explained along with materials used and the changes necessary for lead-free. At the first screen you can select the soldering process, equipment set-up, quality control, defect guide and CD ROM operation. The defect guide browser provides examples of defects rather than defect categories which makes it easy to compare process problems with the disk content. Clicking on the photograph provides a full screen view with an explanation of the possible causes. .Also included on the CD ROM are procedures for Parts Per Million Monitoring, process control procedures and set-up methods. A spread sheet is provided which may be used for defect monitoring using the PPM procedures.
