Our next SMART Group Defect Guide is entitled “Printed Circuit Surface Finish Defect Guide” and will be released on Wednesday 29th March. This relates to different surface coating on PCB and the common process and assembly failures that may occur. It shows issues at good receipt and the typical assembly related problems. The guide provides example images of satisfactory surface finishes as a reference source and many common defect examples. It is well known the surface finishes can create joint failures and other reliability problems so good solderability is key to success. The guide covers gold, tin, solder levelling, Copper OSP and other process defects

“Conformal Coating & Cleaning Defect Guide 2” The updated guide is also being produced and circulated to industry free. The colour guide provides examples of the most common process defects and common cures. The guide also features many of the common and less obvious defects seen during production. It will feature defects associated with components, printed circuit boards, design, materials, assembly and rework. It will also include some of the issues which may be seen on field returns. This guide was kindly supported by Electrolube & Humiseal go to http://coatingguide.smartgroup.org/
Each Defect Guide including Lead-Free have been produced by Bob Willis for the SMART Group
