Foreword
The text of document 47/1989/FDIS, future edition 2 of IEC 60749-20, prepared by IEC TC 47,
Semiconductor devices, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60749-20 on 2009-09-01.
This European Standard supersedes EN 60749-20:2003.
The main changes are as follows:
– to reconcile certain classifications of EN 60749-20 and those of IPC/JEDEC J-STD-020C;
– reference EN 60749-35 instead of Annex A of EN 60749-20:2003;
– update for lead-free solder;
– correct certain errors in EN 60749-20:2003.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2010-06-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-09-01
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 60749-20:2008 was approved by CENELEC as a European
Standard without any modification.
