Defense systems and its manufacturers are often blamed for not embracing new and innovative technologies to manufacture products compared to its commercial counterparts. Commercial product manufacturers are known to think “outside the box” in coming up with new products which are cheaper, have fewer parts, and easier to manufacture using automation. Automation leads to consistent quality products which are reliable and reproducible. Implementing some of these producibility design practices into defense systems will greatly reduce the cost and insertion time for new products.

First published in the 2012 IPC APEX EXPO technical conference proceedings. Signal integrity analysis has shown that printed circuit board (PCB) insertion loss is a key factor affecting high speed channel performance. Determining and controlling PCB inser

Manufacturers test to ensure that the product is built correctly. Shorts, opens, wrong or incorrectly inserted components, even catastrophically faulty components need to be flagged, found and repaired. When all such faults are removed, however, functional faults may still exist at normal operating speed, or even at lower speeds. Functional board test (FBT) is still required, a process that still relies on test engineers’ understanding of circuit functionality and manually developed test procedures. While functional automatic test equipment (ATE) has been reduced considerably in price, FBT test costs have not been arrested. In fact, FBT is a huge undertaking that can take several weeks or months of test engineering development, unacceptably stretching time to market. The alternative, of selling products that have not undergone comprehensive FBT is equally, if not more, intolerable.
