WebJan 22, 2013 · 03 Apr 2024. CAF is metal filaments that can grow from copper via-hole plating along the glass fibres embedded in PCB materials such as FR4. They can eventually short via holes out, which is bad news for the reliability of products in the field, and also for warranty costs and customer satisfaction. WebJun 17, 2024 · Standards Regulating PCB Electrical Clearance. While clearance between traces on a similar layer is commonly discussed, little is mentioned about keeping traces apart when they’re on different layers. Are there any standards that PCB designers can refer to in this matter? Yes! IPC2221B. IPC2221B is a common reference standard in PCB …
