Hello, We are using a PCB with thickness 3.2mm 4 layer and lot of through hole via's of diameter 0.4mm. We specified our PCB vendor to do plugging. Now we have big problems, that after 1..4 weeks we measure a low resistance between track's/via's of

Q1. Is this a standard process for plugging? A1. Not as such. We checked both IPC-6012 and IPC-SM-840. Neither comments on plugging. So, your fabrication notes rule the day. Q2. Is this okay for such thick PCB's or is it mandatory to use a special pl

Voids are a plague to our electronics and must be eliminated! Over the last few years we have studied voiding in solder joints and published three technical papers on methods to "Fill the Void." This paper is part four of this series. The focus of this work is to mitigate voids for via in pad circuit board designs. Via holes in Quad Flat No-Lead (QFN) thermal pads create voiding issues. Gasses can come out of via holes and rise into the solder joint creating voids. Solder can also flow down into the via holes creating gaps in the solder joint. One method of preventing this is via plugging. Via holes can be plugged, capped, or left open. These via plugging options were compared and contrasted to each other with respect to voiding. Another method of minimizing voiding is through solder paste stencil design. Solder paste can be printed around the via holes with gas escape routes. This prevents gasses from via holes from being trapped in the solder joint. Several stencil designs were tested and voiding performance compared and contrasted. In many cases voiding will be reduced only if a combination of mitigation strategies are used. Recommendations for combinations of via hole plugging and stencil design are given. The aim of this paper is to help the reader to "Fill the Void."

This paper deals with the thermal effects of joule heating in a high interconnect density, thin core, buildup, organic flip chip substrate. The 440 μm thick substrate consists of a 135 μm thick core with via density of about 200 μm. The typical feature sizes in the substrate are 50 micron diameter vias is the core/buildup layers and 12 micron thick metal planes. An experimental test vehicle is powered with current and the temperature rise was measured. A numerical model was used to simulate the temperature rise in the TV.
