What Is a Rigid-Flex PCB?
A rigid-flex PCB combines rigid circuit board sections and flexible interconnects in one continuous structure. Components are mounted mainly on
What Are the Materials Used for HDI PCBs?
HDI boards place more interconnections into a smaller area than conventional multilayer PCBs. As dielectric layers become thinner, microvias become
1+N+1 vs 2+N+2 HDI Stack-ups: Which One Does Your Design Need?
Choosing between 1+N+1 and 2+N+2 comes down to one question: can a single build-up layer per side complete all the
What Is an HDI PCB, and When Does a Design Need One?
Conventional through-via multilayer construction can become impractical when fine-pitch packages and limited board area leave too little room for escape
Multilayer PCB Layout Guide: Placement, Routing, Vias, and DFM
A reliable multilayer PCB layout depends on more than fitting every connection onto the available layers. Once the layer count
PCB Stack-Up Design: How to Define Layer Count, Layer Order, and Construction Before You Route
Stack-up decisions made before routing begins determine whether your board passes EMI pre-compliance, whether controlled-impedance traces can be manufactured within tolerance,
