PCB Return Path Via Placement: Where the Current Goes Back 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 return path via placement from the perspective of a…

Via to Trace Clearance: The Clearance Rules Multilayer PCBs Need Routing a multilayer board is mostly an exercise in deciding where copper belongs. Traces carry the signal, planes carry the return current, and vias stitch the two together. What gets far less attention is the space that must be left…

PCB Reference Plane Split Crossing: When the Return Path Breaks 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 reference plane split crossing from the perspective of a…

PCB Jitter Budget Planning: Dividing the Timing 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 jitter budget planning gives you a practical advantage when you…

PCB Eye Diagram Interpretation: Reading the Opening 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 eye diagram interpretation gives you a practical advantage when you…

High Frequency Traces and Data Buses: Layout Rules Almost every layout guide repeats the same advice: keep digital and analogue grounds separate. Anyone who has laid out a real board knows how difficult that is to achieve in practice, and the reason is that the advice describes a conclusion rather…

PCB Time Domain Reflectometry Check: Seeing the Bumps 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 time domain reflectometry check gives you a practical advantage…

PCB Channel Loss Measurement on A Coupon: How Much Signal Survives 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 channel loss measurement on a coupon from the…

PCB Copper Foil Roughness and Loss: A Bumpy Surface 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 copper foil roughness and loss from the perspective of a…

High-Speed PCB Simulation: Three Design Strategies Teams solving the same physics problem arrive at very different places, and the difference is rarely engineering skill. In telecom, computing and imaging, high-speed boards are designed to three distinct postures, and understanding which one a design has fallen into is often the first…
