PCB Maintenance Schedule: Servicing Before Failure 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 years. This article explains PCB maintenance…

PCB Panel Warpage: When the Board Bends 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 years. This article explains PCB…

EV Charging PCB Design: Copper, Voltage and Heat A charging station is a power converter with a network connection, and its board has to carry mains current, switch it at high frequency and remain safe when something fails. That combination puts requirements on the copper, the spacing and the material…

PCB Calibration Schedule: Keeping Tools Honest 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 years. This article explains PCB calibration…

Impedance Matching in PCB Design: Why It Matters Impedance is easy to ignore on a slow board and impossible to ignore on a fast one. When the rise time of a signal becomes comparable with the time it takes to travel along a trace, the trace stops behaving like a…

PCB OEE Measurement: Availability, Speed, Quality 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 OEE measurement gives you a practical advantage when you choose a…

Radiated Emission Troubleshooting: Finding the Source A product that fails a radiated emission limit has one or more current loops that are acting as antennas. Finding which loop is the work, and the tools for it are cheap. Start With the Cables In most products that fail, the emission comes…

EMC Pre-Compliance Testing Before the Accredited Lab The accredited test house reports whether the product passes. The pre-compliance work in the company’s own facility is what determines whether it passes on the first visit, and it costs a fraction of a repeat test. What Pre-Compliance Achieves It finds the large…

Board Level Vibration Testing: Fixture Design and Failure Modes Vibration testing of a populated board is where mechanical design, material choice and soldering quality meet. A test can be run in a few hours, yet the result depends almost entirely on how the board was held, how the excitation was…

PCB Consignment Stock: Parts on Loan 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 consignment stock from the perspective of a PCBA factory floor, covering using consignment…
