BEDFORD, UK -- The UK SMART Group will release a new guide to solderable finishes and their defects in the next month.

The upcoming "Printed Circuit Solderable Finish Defect Guide" will cover various surface coatings on PCBs and common process and assembly failures that may occur. It reveals typical assembly-related problems.

Also, an update to the conformal coating guide is being readied. "Conformal Coating & Cleaning Defect Guide 2," a free color guide, provides examples of common process defects and their cures. The guide also features many 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.

SMART Group's first “Lead-Free Defect Guide” produced in 2007 and updated in 2008 was circulated worldwide with over 1,000 free downloads. The guide is also provided to engineers to download free.
