Has anyone heard of vias cracking (barrel from pad) when being wave soldered. Was told this was a big problem by contract pcb designer, he always tent vias because of this. The reason was that the solder filling the vias caused stressing and then sep

Knee of barrel and pad crack: Caused by thermal stress during soldering, because epoxy expands in the "z" 3X more than "x" or "y" which are restricted by the fiber. Related to: * Design of pads too large relative to hole diameter * Temperature at o

If a picture is worth a thousand words, the new H revision of IPC-A-600, Acceptability of Printed Boards, is a priceless work of art for fabricators and assemblers, particularly inspectors and product developers. IPC — Association Connecting Electronics Industries® announces the new releases of IPC-A-600H and its companion document the C revision of IPC-6012, Qualification and Performance Specification for Rigid Printed Boards.

This presentation surveys the most significant via and via-related laminate failure mechanisms from past to present using data from current induced thermal cycling (CITC) testing, failure analysis, and other sources. The relative life and failure modes of thru vias, buried vias, and microvias (stacked vs. non-stacked) are compared, along with the affect of structure, materials, and peak temperatures on the above. The origin of via-induced laminate failures such as "eyebrow cracks" and Pb free related internal delamination is also explored.

First published in the 2012 IPC APEX EXPO technical conference proceedings. Pad Cratering opens circuits. This occurs when the resin crack (fracture) migrates through a copper trace or via. This happens at assembly, in service or during handling. When com
