For years the means to test flexible circuits or Flexible Hybrid Electronics (FHE) have varied. From very simple and straight forward continuity and isolation testing seen in traditional printed circuit board (PCB) substrates using grid testers to now flying probe testers offering the end-user/contract manufacturer or original equipment manufacturer (OEM) more flexibility in the production process of these circuits. However, time is not 1999 anymore. FHE’s have become a standard product in almost anything electronic built today. From wearables, smart devices, to 5G products. They are not only the highway of signals connecting one device to another but these highways have now embedded components built-in along with RF circuitry and other proprietary OEM intelligence.
