JULY 2020 I DESIGN007 MAGAZINE 59 Did You Get What You Paid For? Once your boards arrive from the offshore fabricator, yields become your next concern. Again, we encourage multi-dimensional anal- ysis of the production. Instead of targeting a percentage yield and checking a box, consider the consistency of yields over time, along with the boards' functional reliability in the end product. Long-term reliability is a key measure. Counterfeit components routinely find their way into PCBs manufactured offshore (Figure 2). Some substandard parts are easy to spot, but not so much with others. Counterfeit com- ponents in your offshore PCB may stand up to initial testing, and then fail after your prod- uct is in use. This can impact product per- formance, reduce customer satisfaction, and, eventually, tarnish your reputation in the mar- ketplace. Conclusion Making the right decision about domestic versus offshore PCB manufacturing depends on a thorough cost-benefit analysis. Your results will vary depending on volume and design requirements. We encourage our cus- tomers to look for the hidden costs in offshor- ing and seriously consider its less quantifiable pain points.

Würth Elektronik offers solutions and stan- dard-compliant reference designs that make this copper-saving cabling, which originates from the automotive sector, usable for industrial applications. (Source: Wurth Elektronik) As Würth Elektronik is not able to present new products to customers and interested parties in personal contact at trade fairs due to the COVID-19 pandemic, the manu- facturer of electronic and electromechanical com- ponents has now set up a virtual exhibition stand. Instead of visiting a trade fair, visitors will find an attrac- tive online presentation of product innovations and the ability to have direct conversation in the chat. The Würth Elektronik team offers a cre- ative answer to the current situation with its virtual trade fair stand. Interested develop- ers and manufacturers can use this platform to stay in close, personal contact with the manufacturer.
