PCB Panel Flatness Requirement: A Panel That Stays Flat 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 panel flatness requirement gives you a practical advantage…

Releasing Gerber Files and Fabrication Data to a PCB Manufacturer Releasing a board for manufacture means handing a fabricator a set of files that describe the copper, the solder mask, the legend and the holes without ambiguity. Almost every format in that set is a convention rather than a standard…

PCB Board Warpage Measurement: How Flat the Board Really Is 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 board warpage measurement from the perspective of a PCBA…

PCB Solder Paste Volume Verification: Measuring What Was Printed 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 solder paste volume verification gives you a practical…

Solder Paste Mask Openings on Pads: What to Open and What to Close The paste mask layer is the least examined layer in a finished design and one of the most consequential. It decides where the stencil will have an opening, and therefore where solder paste will be printed, and…

PCB Reversed Part Detection: Facing the Wrong Way 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…

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: Fitting the Right Component 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 when…

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: Finding the Empty Pads 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…
