Medical Electronics PCB: Reliability and Compliance Demands A medical electronics PCB sits in a product where failure has consequences beyond inconvenience. A monitor that stops reporting, an infusion pump that dispenses the wrong volume or a diagnostic instrument that drifts out of calibration can injure a patient. That is why…

Phone PCB vs Tablet PCB: What Actually Differs A phone and a tablet run the same operating systems and use similar chipsets, so it is easy to assume their boards are alike. They are not. The constraints that shape each design pull in different directions, and the resulting boards differ…

Space Grade PCB Manufacturing: Reliability Above All Hardware that leaves the atmosphere cannot be repaired, which changes every engineering decision on the board. A space grade PCB is specified not to perform well on average but to survive every foreseeable condition, and the manufacturing discipline that follows is closer to…

OLED Display PCB Cost Factors: Materials, Process and Yield An OLED display PCB is not a large board, but it carries an unusual combination of requirements: a very fine-pitch bonding area for the display driver, a high-speed interface to the host, a thin overall profile and a mechanical outline that…

AR Device PCB: Design Challenges for Wearable Displays An augmented reality headset is one of the hardest packaging problems in consumer electronics. Two displays have to be driven at high frame rate, several cameras have to be captured and processed, a radio has to work beside all of that, and…

Telecom PCBA: Rugged Design for Continuous Operation A telecom PCBA is designed around a requirement that most consumer boards never face: it has to keep working. Equipment in a base station, an optical node or a switching centre is expected to run continuously for years, at temperature extremes, with no…

Ceiling Fan PCB: Technology and Design Explained A ceiling fan is one of the oldest motorised appliances in the home and one of the most recently reinvented. The mechanical part has barely changed in a century, but the control electronics have moved from a single capacitor and a pull chain…

Fire Alarm PCB: A Complete Beginner Guide A fire alarm panel is a product that must work after years of sitting quietly, and must then work correctly on the one day it matters. That requirement, rather than any exotic electrical function, is what shapes the board inside it. A fire…

How an LCD Display PCB Is Built and Bonded An LCD display is a glass sandwich that needs a driver, a backlight and a mechanical frame, and the board behind it has to serve all three. Unlike a board that only carries electronics, an LCD display PCB is part of…

Direct Bonded Copper PCB: Differences from Standard Materials Direct bonded copper sits at the high end of thermal substrate technology. It joins thick copper to a ceramic base at high temperature, producing a conductor that carries hundreds of amps and spreads heat across the ceramic at the same time, which…
