The End Launch series includes a range of connectors designed for seamless attachement to the side of a PCB. These connectors are widely used in optoelectronic communication fields, such as 5G testing. Unlike traditional connectors, the End Launch series features a solder-free center conductor and a screw-locking outer conductor. This design minimizes the risk of PCB damage due to soldering issues and supports repeated use, lowering overall costs. Comparative tests on identical test boards have demonstrated that Flexi's End Launch series connectors offer substantial benefits in both pricing and delivery time.
