As the miniaturization trend in electronics continues, rigid-flex PCBs grow in popularity. This is because they require up to 60 percent less space than standard PCBs.
Rigid-flex PCBs feature rigid and flexible circuit substrates that are laminated together, but allow for components to be mounted on both sides. Equally important, their integrated circuits electrically connect the system together, eliminating the need for connectors or connecting cables between the sections.
Aerospace companies have used rigid-flex PCBs in spacecraft since the 1960s to replace wiring harnesses. These PCBs were also used in the first commercially available mobile computer, and today can be found in laptop computers, wearable technologies, medical devices, test equipment and satellites.
Teledyne Printed Circuit Technology (TPCT) designed and manufactured rigid-flex PCBs from the mid-1960s until 2016, when the company was sold to Firan Technology Group (FTG) Circuits Inc. PCBs made by TPCT were used extensively in the defense, aerospace, and oil and gas industries for many decades.
