We have a discussion going on with the IPC 610 B figure 4-23
and 4-24 which are on page 57. It seems we cannot come up with
a majority rule on the insertion and soldering techniques of
the coated capacitor.
The statement which we are concerned with: Exhibits all around
good wetting on secondary side and lead coating meniscus is not
visible within connection on solder side. We cannot understand why
solder side is also called secondary side in the same sentence.
(Per the view 4-2 these mean the same.)
Our situation is, we have some meniscus into the solder on the top
side or primary side with little or no wetting. We cannot ensure that
the vertical fill of solder is 75% per table 4-1 Class 2.
Also, there does not appear to be a minimum amount of lead space
between the solder connection and the meniscus in 610 B.
This application has been changed from 610 A TO 610 B.
Thanks for any clarification we can get on this...
