Removing PCB Routing Quickly During Layout Revisions Every layout goes through a phase where the routing that exists is no longer the routing that is wanted. A part moves, a net class changes, a differential pair has to be re-matched, or a design revision arrives after the board is already…

PCB Wrong Part Detection: 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 wrong part detection gives you a practical advantage…

Power Delivery System Design for High-Speed PCBs Supply voltages keep falling and supply currents keep rising. When a core moved from a 130 nm process to a 90 nm process, the rail that had been comfortable at a higher voltage was expected to run near 1.2 V, with a larger…

PCB Missing Part Detection: A Practical Manufacturing Guide 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 Component Counter Verification: Design and Assembly Considerations 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 component counter verification gives you a practical advantage when…

PCB Riveting and Fusion Technology in Multilayer Lamination Before a multilayer board is pressed, the inner layers have to be held in the right position relative to each other. If they move during the lamination cycle the board comes out with layer-to-layer misregistration, and misregistration on a dense board ends…

PCB Reel Splice Quality: Process Details and Inspection Points 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…

Multi-CPU Parallel Computer Systems: Hardware and Software Design A parallel computer built from several processors on one board changes the economics of a compute platform. Instead of pushing a single device to its clock limit, the computation is split across processors that each keep their own local memory and run…

PCB Feeder Calibration: What Matters on the Production Line 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…

PCB Placement Nozzle Selection: What Matters on the Production Line 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 placement nozzle selection from the perspective of a PCBA…
