Coping with the Risk of Board Flexure Damage to Multilayer Ceramic Capacitors [2] October 01, 2007 By: Patrick Gormally, John Bultitude, and Vito Coppola [3] Find more content on: Components [4] Techniques are emerging to minimize the incidence of a PCB component defect that can cause problems in devices in the field. Rigid flex circuits combine rigid boards & flexible circuits into one circuit. If, ultimately, the PCB design requires the utilization of rigid-flex, designers should be more flexible and less rigid in their thinking to improve yields and decrease investment. Absolute is prepared to manufacture any step in your process. To minimize these defects and improve the throughput of the manufacturing process, many companies use a process called panelization, resulting in a PCB panel. It publishes the most widely used acceptability standards in the electronics industry.
