Re-tinning / RoHS

Key points for re-tinning of electronic components

Réétamage RoHS

The RoHS directive upset the world of electronics by banning the use of lead, which was part of many alloys.

Previously, components were only re-tinned in rare cases, for example, to remove gold from component legs to make the soldering more reliable.

One of the main virtues of lead is the much lower re-soldering temperature of electronic boards than that of pure tin (around 215°C instead of 240°C) and the absence of whiskers, a monocrystalline structure that develops on pure tin soldering over time which can lead to short-circuits.
