White Knight PCB, a division of Quarter Century Design, introduced today a new PCB design decision tool—a PCB “Make vs Buy” worksheet. Ideal for product managers, design engineers, and buyers alike, the White Knight “Make vs Buy” PCB worksheet poses 15 questions along with varying scenarios reflecting important PCB design criteria.
Numerical scoring values are suggested for each of the 15 questions. Once the “Make vs Buy” worksheet is completed, the 15 scores are totaled. Their sum (score) is then compared to predetermined scores for 5 “Make vs Buy” recommendations. These recommendations will help managers, engineers, and buyers make important outsourcing “Make vs Buy” decisions.
To request a free PCB design “Make vs Buy” worksheet, visit www.WhiteKnightPCB.com or contact Steve Stoehr at 937-434-5127, ext. 109 or info@WhiteKnightPCB.com.

DesignCon is always a great place to check out the latest PCB layout and simulation software tools. During DesignCon 2018, Guest Editor Kelly Dack met with Sam Chitwood, a product engineer with Cadence. Sam explained how the Cadence Sigrity simulation software now allows users to make decisions early in the design process, and how this can help optimize the design of the power delivery network and ensure signal integrity in complex PCBs.

Schematic verification is a part of the hardware engineer’s responsibility just as PCB layout verification is an accepted part of the PCB designer’s responsibility. However, with today’s circuit designs becoming more and more complex, time-consuming manual schematic verification is no longer an option. Manual verification of a complex circuit introduces significant risk by not identifying schematic design errors that are, in turn, passed to the downstream processes and ultimately to the fabricated board.

Years ago, I held a position in an EMS company where projects were analysed before manufacturing. We found that even some of the best and most innovative circuits could not be manufactured. Why? Because the PCB designer, an electronic engineer, was not acquainted with the fabrication process. He had no idea about technological requirements necessary for electronic production. I know another designer who learned, finally, the importance of the thermal relief pad for heat restriction during reflow for a good soldering. His response? “Oh, was that what they were for? And to think I worked so much to remove them!”
