PCB Design Preparation: Goals, Libraries and Standards Layouts that run late rarely fail because the routing was too difficult. They fail because the work started before anyone agreed what the board was for, or before the footprint of a critical part had been checked against its datasheet. PCB design preparation…

High-Speed Routing on Multilayer PCB: Stackup and Rules

High-Speed Routing on Multilayer PCB: Stackup and Rules Speed changes the rules of layout. At low frequency a trace is a wire; at high frequency it is a transmission line, and its behaviour depends on the structure around it rather than on the netlist. High-speed routing is the practice of…

PCB Coating Thickness Measurement: How Thick It Went On 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 coating thickness measurement gives you a practical advantage…

PCB Production Flow: From Design Files to Finished Board A finished circuit board is the output of two very different sequences: a design sequence that produces data, and a production sequence that turns that data into copper and laminate. The two meet at the manufacturing files. Understanding what happens after…

PCB Inspection After Fabrication: What to Check Once a board has been designed and built, the difference between a working assembly and a batch of scrap is measured at inspection. The checks are unglamorous, but each one maps to a specific failure mode that would otherwise be discovered by the…

Glass Fiber Board vs FR-4: Composition and Applications Ask for a glass fibre board and you may be handed something that belongs in a building, not in an electronic product. Ask for FR-4 and you will get the material that almost every rigid circuit board is made from. The two…

PCB Conformal Coating Masking Method: Covering What Matters 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 conformal coating masking method from the perspective of a PCBA factory…

PCB Jumper Wire Repair Method: Going Around a Break 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…

Flying Wires and Manual Placement in PCB Layout Autorouters have improved enormously, yet almost every professional layout still contains material that was placed and routed by hand. Part of that is judgement — a tool cannot know which return path matters — and part of it is the humble flying…

PCB Design Inputs and Steps: From Schematic to Gerber A board only turns out well if the people laying it out have the information they need, and most expensive respins trace back to something that was never supplied rather than to something the designer got wrong. The PCB design inputs…
