| Title | Semiconductor devices - Mechanical and climatic test methods - Part 20: Resistance of plastic encapsulated SMDs to the combined effect of moisture and soldering heat |
| Project Number | 21363 |
| Abstract/Scope | IEC 60749-20:2008 provides a means of assessing the resistance to soldering heat of semiconductors packaged as plastic encapsulated surface mount devices (SMDs). This test is destructive. This second edition cancels and replaces the first edition published in 2002 and constitutes a technical revision. The main changes are as follows: - to reconcile certain classifications of IEC 60749-20 and those of IPC/JEDEC J-STD-020C; - reference IEC 60749-35 instead of Annex A of IEC 60749-20, Edition 1; - update for lead-free solder; - correct certain errors in the original Edition 1. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
