Reliability Validation Plan for High-Performance ECU PCBs

Once installed in a vehicle, a high-performance ECU must operate for years under fluctuating temperatures, vibration, humidity, and electromagnetic interference. The reliability of its PCB directly determines overall vehicle safety. Many projects pass every functional test at the laboratory prototyp

Core Principles and Standard Calculation of PCB Trace Width vs. Current-Carrying Capacity

Many hardware engineers habitually apply fixed trace-width templates when routing — 10 mil for 1 A, 30 mil for 3 A, and so on. Yet in volume production, traces still overheat, laminate carbonizes, and long-term aging failures appear. The root cause is that simplified rules of thumb ignore the underl

Rapidly Pinpoint the Root Cause of Overheating! CEM-1 PCB Thermal Failure Troubleshooting and Mass-Production Corrective Action Guide

During the mass production and field application of CEM-1 PCBs, problems such as excessive component temperature rise, intermittent overheating, high-temperature failure, and premature aging under thermal cycling occur frequently. When confronted with such failures, many engineers blindly add copper

Standardizing a PCB Circular Pad Library and Version Control to Reduce Volume-Design Risk

Recurring circular pad design errors in many hardware teams do not stem from individual engineer negligence, but from the absence of a unified, standardized pad library. When different designers build their own pads, pads sharing the same name end up with inconsistent dimensions and solder mask defi

Why 1.6mm Became the Gold Standard for PCB Thickness

In PCB design and selection, 1.6mm is a number you simply cannot get around. More than 70% of circuit boards use this thickness. Yet the figure did not come from any theoretical formula — it is the "performance–cost–process" equilibrium point forged by decades of high-volume manufacturing practice i

Don't Blindly Plug Vias! The Real Differences Between PCB Via Plugging Processes

In PCB design and manufacturing, via plugging is a special process that engineers very easily overlook. Many hardware designers simply assume that plugging a via just means blocking it to stop solder from flowing through, and they confuse the essential differences between solder mask ink plugging, r
