These PCBs create a more challenging design for rigid-flex manufacturers, but we’ve been able to supply successful designs with full compliance and reliability. By engineering these in a 3D environment, we’re able to achieve spatial efficiency and incorporate folds and flexes to help you meet the desired shape that works best with your application. A rigid-flex printed...
HDI printed circuit board have a higher density per unit circuit than traditional PCBs. They use a combination of buried and blind vias and microvias (0.006 inches in diameter or less). A high-density board is a PCB that has one or more of the following features: Through and buried vias Through surface-to-surface vias At least...
With the rapid development of wireless communication, radar systems, satellite communication, automotive electronics, and high-frequency industrial applications, RF (Radio Frequency) and microwave PCB technology has become increasingly important. Unlike conventional low-frequency PCB designs, RF and microwave circuits operate at higher frequencies where even small variations in PCB structure can significantly affect electrical performance. Common design...
1. What Is a Flexible PCB? A flexible PCB (Flex PCB) is a specially engineered printed circuit board made from flexible materials such as polyimide. It is designed to bend, twist, or fold without damaging the circuit. Key Characteristics: Built on flexible substrates (e.g., polyimide) Designed for dynamic or static bending High reliability under mechanical...
