**Soldering** is the permanent electrical joining of components and wires onto a [[pcb-en|printed circuit board]] or a piece of perfboard, by melting an alloy that provides both the mechanical bond and the electrical contact.

## In the project

This is the basic gesture of building electronics: populating a PCB, wiring up a power supply, making a connection that must not move. It stands opposite **plug-in connectors** (JST, headers), which are preferred for anything that has to remain demountable (see [[ecoconception-en|eco-design]]). On the project safety side, soldering is done at a fume-extracted bench, with the right [[epi-en|PPE]] and after training, following the workshop rules under [[securite-et-qualite-en|safety and quality]].

*The finer techniques, covering SMD soldering, reflow, desoldering and joint inspection, belong to the electronics lab sessions and to the **dedicated workshop**. The wiki places soldering within the project without detailing the gesture itself.*
