PCB Placement Nozzle Plan: Laying It Out First 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 plan from the perspective of a PCBA factory floor,…

Non Solder Mask Defined vs Mask Defined Pads Two pads of identical copper area can produce joints with very different reliability, and the difference is whether the solder mask opening is larger than the copper or smaller than it. A non solder mask defined pad exposes the whole copper feature…

Rigid-Flex Transition Design Rules A rigid-flex board is two technologies joined at a boundary that has to survive being bent, laminated and soldered. The transition zone is where the layers change, where the stiffness changes and where most of the manufacturing and reliability problems occur. Designing it well means understanding…

PCB Placement Nozzle Limits: Where the Edges Are 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 Placement Nozzle Data: What the Numbers Say 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 Placement Nozzle Setup: Getting Ready 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 setup from the perspective of a PCBA factory floor, covering setting…

Barcode Label Quality on PCB Assemblies and Panels A barcode label is the smallest and cheapest part of a PCB assembly, and the one most likely to break traceability. If the label cannot be read after reflow, or falls off in the cleaning line, the board loses its identity and…

PCB Feeder Setup Selection: Choosing What Fits Electronics manufacturing has become a discipline of small details.
