PCB Bed of Nails Probe Wear: When the Needle Stops Touching Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB bed of nails probe wear gives…

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…

PCB Laser Depaneling: A Cut With No Touching Buyers and engineers often focus on the finished product and forget the production line behind it. In practice, most field failures can be traced back to process decisions made during assembly. Understanding PCB laser depaneling gives you a practical advantage when you…

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…

PCB Fixture Design for Test: Holding the Board Still Electronics manufacturing has become a discipline of small details. Solder paste volumes, placement accuracy, temperature profiles and inspection limits all add up to the final result. This guide looks at PCB fixture design for test from the perspective of a PCBA…

PCB Floor Life Tracking on the Line: The Clock on Every Bag Modern electronics depend on boards that are assembled correctly the first time. Every product – a phone, a charger, a medical instrument or an industrial controller – relies on thousands of solder joints that must conduct current for…

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…
