PCB Silkscreen Traceability: A Practical Manufacturing Guide 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 silkscreen traceability from the perspective of a PCBA factory floor, covering tracing…

PCB Silkscreen Control: A Practical Review for Manufacturing Teams 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 silkscreen control from the perspective of a PCBA factory floor,…

Silkscreen Design Rules For PCB Assembly The silkscreen, also called the legend, is the printed layer that carries component outlines, reference designators and polarity marks. It exists for the people who assemble, inspect and repair the board, and its rules are written to keep it readable without interfering with the…

Teflon PCB Design Guide A teflon board, more precisely a board built on a polytetrafluoroethylene laminate, is chosen for its electrical properties. The dielectric constant is low and stable with frequency and the loss is very low, which is what a microwave circuit, an antenna or a very high speed…

Copper Foil Surface Profile and High Frequency Signal Loss At low frequencies the surface of a copper trace is just a surface. At microwave frequencies the current no longer flows evenly through the conductor, it crowds towards the outside, and the texture of the copper becomes part of the electrical…

Copper Paste Plugging for Vias Copper paste plugging fills a via with a conductive material so that a subsequent plating step can bridge over it and form a flat, connected surface. It is used where a via has to carry current or heat, or where a via has to be…

PCB Silkscreen Specification: Practical Process Controls 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 silkscreen specification from the perspective of a PCBA factory floor, covering specifying silkscreen…

PCB Silkscreen Plan: Practical Process Controls 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 silkscreen…
