SMART Group Launches PCB Surface Finish Defect Guide


Reading time ( words)

SMART Group, Europe's largest technical trade association focusing on Surface Mount and Related Technologies, announces that the "Printed Circuit Solderable Finish Defect Guide" has been printed and is available free of charge.

This next guide in the series relates to different surface coatings on PCBs and the common process and assembly failures that may occur. It illustrates issues at good receipt as well as typical assembly-related problems. Additionally, the guide provides example images of satisfactory surface finishes as a reference source and many common defect examples. It is well-known that surface finishes can create joint failures and other reliability problems; therefore, good solderability is key to success. The guide covers gold, tin, solder levelling, Copper OSP and other process defects.

As an additional resource, the updated "Conformal Coating & Cleaning Defect Guide 2" is finished and available to the industry for free. The color 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 includes some issues that may be seen on field returns. The Conformal Coating & Cleaning Defect Guide 2 was kindly supported by Electrolube & Humiseal, and can be downloaded free of charge by visiting here.

Each of the guides in the Defect Guide series, including Lead-Free, have been produced by Bob Willis for the SMART Group.

Manufacturability: Pad Relief and Mask Relationship to Solder Joint Volume

03/09/2018 | Ken Horky, Peterson Manufacturing
Electronic assembly thermal management has always been an issue but has become more significant as we pack more power and function into a smaller form factor. In recent years, the growing use of LEDs for illumination on a large scale has presented additional thermal demands.

PCB Pad Repair Techniques

01/08/2018 | Bob Wettermann, BEST Inc.
There are a variety of reasons behind pads getting "lifted" completely or partially from the laminate of a PCB. Per the just revised IPC-A-610 Revision G, a defect for all three classes occurs when the land is lifted up one or more pad thicknesses. Lifted pads can occur when a device has been improperly removed or there is a manufacturing defect in the board construction. In any case, as with any repair, the ultimate decision on the ability to repair the pad lies with the customer.

Focus on the New

01/05/2018 | Stephen Las Marias, I-Connect007
It seems like it wasn't too long ago when I was writing about the optimism of the electronics manufacturing and assembly industry going into 2017. Now, here we are again at the beginning of the new year, looking at new trends, disruptive technologies, and emerging markets for 2018. I am also proud to announce our new branding as well as our fresh, new look.
