Polyimide film is one of the most widely used base materials in flexible circuit manufacturing. Its combination of flexibility, thermal resistance, electrical insulation, chemical durability, and dimensional stability makes it well suited for circuits that must bend, fold, or fit into compact electronic assemblies.Unlike...
Rigid-flex printed circuit boards combine the component stability of rigid PCBs with the routing freedom of flexible circuits. They can reduce connector count, save space and weight, and improve reliability in compact medical, aerospace,
Selecting the right base material for a printed circuit board affects more than the initial laminate price. The material influences mechanical strength, thermal reliability, dimensional stability, manufacturability, and the environments in which the finished PCB can operate. FR-4 remains the most widely used rigid PCB material, but...
Printed circuit board tolerances define how much a manufactured feature may vary from its specified dimensions. Every PCB requires tolerances for features such as conductor width, spacing, hole diameter, board outline, copper thickness, layer registration, and overall thickness. However, specifying tighter tolerances than the application requires can...
Core and prepreg materials both provide dielectric insulation within a printed circuit board, but they serve different roles. A core is a fully cured laminate that provides a stable base for copper circuitry. Prepreg is a partially cured resin system that flows during lamination,...
PCB sourcing teams are facing a more complicated material environment than they were a few years ago. Availability pressure is no longer limited to electronic components. Base materials, copper-clad laminates, copper foil, glass fiber, resin systems, surface finishes, and long-lead components can all affect whether a flex,...
In high-reliability electronics, a flexible circuit or printed circuit board cannot simply function when it leaves the factory. It must continue performing through temperature cycling, vibration, bending, humidity, current load, installation stress, and years of field use.IPC Class 3 provides a recognized framework for flex,
Medical devices are becoming smaller, smarter, and more connected, creating greater demand for compact electronics that can perform reliably in tight spaces. Flexible printed circuits help support this shift by enabling lightweight, space-saving designs for wearables, diagnostic equipment, surgical tools, and...
Point‑of‑care (POC) medical devices are designed to deliver diagnostics and monitoring directly at the patient’s location rather than in centralized laboratories. These systems must be compact, portable, energy‑efficient, and highly reliable. Flexible printed circuits (flex PCBs) are frequently used in these devices because they...
Space Tech Expo USA 2026 brought together a wide range of companies working across satellites, launch systems, defense space programs, lunar infrastructure, in-space manufacturing, robotics, power systems, optical communications, RF technology, testing, interconnect, software, and advanced components. Held June 2-4 in Anaheim, California, the event offered a strong look...
As electronic devices become more powerful and compact, managing heat has become one of the most important challenges in product design. Excessive heat can reduce performance, shorten component lifespan, and increase the risk of failure. This is especially true in applications that rely on high-power LEDs, power semiconductors, and densely...
Electric vehicles are often discussed in terms of batteries, motors, and charging speed. But behind all of that performance is a complex electronics architecture that has to survive heat, vibration, current load, tight packaging, and electromagnetic noise. From the battery pack to the onboard charger to the charging station itself,...
When engineers need a circuit that can bend, fit into tight spaces, or replace bulky wire harnesses, flexible circuitry is often the right direction. But once a design also requires component support, connector stability, or selective stiffness, the decision becomes more specific: should the...
The future of intelligent electronics is becoming smaller, faster, smarter, and more connected — and few events showcase that transformation better than Sensors Converge 2026.Held at the Santa Clara Convention Center, Sensors Converge brings together engineers, innovators, semiconductor leaders, embedded system developers, AI companies, automotive technology firms,...
Dynamic flex PCBs are where flexible circuit design stops being “just about fitting in tight spaces” and starts being about surviving motion—hundreds of thousands or even millions of bend cycles without cracking, drifting out of spec, or failing at the worst possible time.If you design wearables, medical...
