PCB Partial Discharge Testing: Detecting Weak Insulation A partial discharge is a small electrical breakdown inside insulation. It does not bridge the gap completely, so the board keeps working. That is exactly why the defect is dangerous. The discharge erodes the material a little at each pulse, and the damage…

PCB Arc Tracking Prevention: What Buyers and Engineers Should Check 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…

PCB High Voltage Isolation Barrier Layout: Design, Process, and Quality Notes 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 high voltage isolation barrier layout gives…

PCB Insulation Coordination for High Voltage: Design, Process, and Quality Notes 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 insulation coordination for high voltage from the perspective…
