HI there,
The only standard I know for through holes is in your IPC-610-C. Please noted that we are in revision C now. Page 6-1 States
" The criteria should be based on design, process capability and performance requirements". Other than that I would say to go to the Supported Holes table on page 6-5. I know not a lot of help but maybe some of our great ones will come up with a better answer.
Any Way I just wanted a reason to tell every one Merry Christmas. To be careful and Happy New Year.
2000 was here before I knew it. My age is talking. Hope to hear from everyone 2001.
Bye
Nancy T.

Hello Folks:

In IPC-A-610, Section 10.2.7 "J Leads", there is
special dispensation given to permit the absence of
side fillets by design such as in the case of leads
made from preplated material (bare edges). We
currently have a component supplier that manufactures
a thru-hole part for us that is made from preplated
material and the wetting action on the cut sides has
come into question. No actual joint failures of any
kind have ever been reported but inspection continues
to denote these as a "non-conformance".

Does anyone know of any standards or guidelines for
this type of condition on a thu-hole part ?

Thanks,
