Hi All,

We currently have a modification to a PCA where we have added a capacitor.
Unfortunately the only capacitor suitable for this is a through hole device.
We have therefore asked our supplier to form the legs as follows:











We have had instances where the solder on the left hand leg has not been
sufficient, the leg has come loose and this has worked like a spring. Also
the RTV compound we have also found to be unreliable.

Could some-one please advise of the following:

1.      Is there a better adhesive to use instead of RTV compound?
2.      Is there a quick and easy way for an inspector to check the solder
joint without placing undue stress on the capacitor legs or the solder
joint? We currently asking inspectors to "gently" try to move the leg while
looking at the solder fillet through a microscope to see if there is a
fracture.

Thanks for your help.

Marc.
