Figure 1. PCB pin headers A PCB header, or pin header, is a row (or rows) of conductive pins on a fixed pitch, soldered to a board to provide connection points, jumper positions, or a way to stack boards together. They look trivial, but a header is a connector, and...
Figure 1. best soldering flux There is no single "best soldering flux" — the best one is the type matched to your job. For most electronics work, the right choice is a no-clean or a rosin (RMA) flux: both are mild, non-corrosive once used correctly, and safe on...
Figure 1. melting point of solder The melting point of solder depends entirely on its alloy. Eutectic tin-lead solder (Sn63/Pb37) melts at a single, sharp 183 °C (361 °F), while the most common lead-free alloy, SAC305, melts over a range of about...
Figure 1. pin in paste PCB assemblyLast updated: May 2026 · A process and design guide to paste-in-hole reflow for mixed-technology boards Pin in Paste (PiP) — also called paste-in-hole (PIH), through-hole reflow, or intrusive reflow — is a way to solder through-hole...
Figure 1. PCA vs PCB vs PCBALast updated: May 2026 · A definitions guide for buyers, engineers, and anyone reading a quote These three acronyms cause endless confusion, but the rule is simple. A PCB (Printed Circuit Board) is the bare board — the substrate with copper...
Figure 1. IC programming during PCBA processingLast updated: May 2026 · A manufacturing guide for embedded engineers and hardware sourcing teams There are two practical ways to load firmware into the chips on a board during PCBA: pre-program the devices before...
Figure 1. FCT test for PCBALast updated: May 2026 · A production-test guide for hardware engineers, test developers, and sourcing teams An FCT test — Functional Circuit Test, often just called functional test — powers up a fully assembled board and exercises it the...
Figure 1. how to clean a circuit board without alcoholLast updated: May 2026 · A practical, safety-first cleaning guide for repair techs, makers, and hardware engineers You can clean a circuit board without isopropyl alcohol, but the right method depends on what you...
Figure 1. printed circuit board assembly processLast updated: May 2026 · A complete walkthrough of how PCBs are populated and verified The printed circuit board assembly process (PCBA) is the sequence that turns a bare board and a pile of components into a finished,...
Figure 1. tinning flux vs regular flux for electronicsLast updated: May 2026 · A practical soldering guide for makers, technicians, and assembly engineers Both tinning flux and regular flux exist to do the same basic job — strip oxide off metal so molten solder can...
