Rigid-flex PCBs combine rigid FR-4 sections with flexible polyimide layers in a single integrated assembly — eliminating connectors and cables between boards, reducing assembly weight, and removing failure points. Superb Automation manufactures rigid

When Chemistry Fails, Physics Takes OverStandard FR-4 desmear uses aggressive permanganate chemistry - it etches epoxy resin smear from hole walls beautifully. But it fails completely on PTFE (Teflon)-based materials used in RF and microwave PCBs. PT
