What are Rigid Flexible PCBs? A rigid flexible printed circuit board (rigid flex PCB or flex-rigid PCB) is a hybrid printed circuit board (PCB) that consists of rigid and flexible substrates laminated together. The rigid sections provide mechanical support while the flexible sections allow dynamic flexing, bending or folding of […]
Introduction Polyimide flex circuits, also known as flexible printed circuits (FPCs), are made using the polymer polyimide as the base substrate material. Polyimide is prized for its thermal stability, chemical resistance, and mechanical toughness. These properties make polyimide ideal for flex circuit applications where flexibility, durability, and reliability are critical. […]
Over the past few decades, electronics have become smaller, lighter, and more portable. Simultaneously, they are packing in more features and capabilities. This trend towards miniaturization and higher functionality is enabled by advances in semiconductor packaging, assembly techniques, and printed circuit board (PCB) technology. One key PCB technology innovation has […]
Introduction A printed circuit board (PCB) serves as the foundation for electronics that require the mounting and interconnection of components. Flexible PCBs provide the ability to bend and flex the board during use, opening up possibilities for flexible and wearable electronics. Double sided flex PCBs take this a step further […]
Introduction to Flexible Aluminum PCBs Printed circuit boards (PCBs) are the backbone of modern electronics. Traditional PCBs use rigid insulating substrates like FR-4 fiberglass to provide mechanical support for copper traces. However, emerging flexible circuit board technologies are enabling smaller, lighter, and more robust electronic devices. One such innovation is […]
Introduction Printed circuit boards (PCBs) are essential components in almost all modern electronic devices. They provide the physical foundation to mount and connect electronic components using conductive tracks etched from copper sheets laminated onto a non-conductive substrate. While the most common type of PCB uses a rigid fiberglass substrate like […]

Rigid flex PCBs (printed circuit boards) combine rigid FR-4 boards with flexible circuits bonded together. They provide solutions for complex electronics with space, weight, or wiring constraints. When designing a rigid flex PCB prototype, engineers must consider factors like layer stackup, materials, spacing, and testing. Designing the Layer Stackup The […]
Introduction to Flex Circuits and Rigid-Flex Printed circuit boards (PCBs) provide the foundation for almost all modern electronics. Traditional PCBs use rigid laminated sheets made of materials like FR-4 glass epoxy. However, many applications require circuits that can bend and flex. Flexible printed circuits (FPCs) and rigid-flex PCBs provide solutions […]
