IEC 60068-2-20:2021 outlines Tests Ta and Tb, applicable to devices with leads and leads themselves. Soldering tests for surface mounting devices (SMD) are described in IEC 60068-2-58. This document provides procedures for determining the solderability and resistance to soldering heat of devices in applications using solder alloys, which are eutectic or near eutectic tin lead (Pb), or lead-free…

L'IEC 60068-2-20:2021 décrit les essais Ta et Tb qui s’appliquent aux dispositifs à broches et aux broches elles-mêmes. Les essais de brasage des composants pour montage en surface (CMS) sont décrits dans l’IEC 60068-2-58. Le présent document fournit des procédures pour déterminer la brasabilité et la résistance à la chaleur de brasage des dispositifs dans les applications qui utilisent des…

The measures in this standard were calculated from detecting and counting violations of good architectural and coding practices in the source code that could result in unacceptable operational risks or excessive costs. Establishing standards for these measures at the source code level is important because they have been used in outsourcing and system development contracts without having…
