You have done well to find a typo in the standard.



I looked this clause 1.4.1.5 in the 610E revision and found it referenced clause 1.4.1.5 Combined Conditions. So the reference to clause 1.4.1.5 in clause 7.3.3. Note 1 was not updated in the 610F revision. Clause 7.3.3. Note 1 should reference 1.5.1.5 Combined Conditions.



I will forward this to IPC staff to get this corrected in the next revision of 610.

Morning Technetters,



Upon reading through IPC-A-610, I came across this section which had me puzzled.  On 7.3.3 Supported Holes - Wire /Lead Protrusion, below Table 7-3, there are Note 1 to Note 3 in small prints.



Note 1:            "For components having pre-established lead lengths that are less than board thickness and the components or lead shoulders are flush to the board surface, the lead end is not required to be visible in the subsequent solder connection, see 1.4.1.5". When I flipped to that 1.4 , it is under the sub-title of Classification with no reference of 1.4.1.5.



My first thought is I better checked with you gurus out there. I hope someone will explain to me on where shall I flipped to in this case. Thanks in advance



Regards,

Ong Seet Leng
