You have not stated what type of component is being affected and how
many.   Has this ever happened be before on the vendor in questioned.  A
photo is worth one thousands words.

Subject: Re: [TN] Cracked component leads

I am looking to rule out the possibility that the crack is further then
the
tin plating. I am pulling parts off the reel that have what appears to
be a
crack in the terminal. We are also seeing a large number of assemblies
with
severed leads after the wave process. The supplier is telling me that it
is
the plating that is cracked not the lead. I hope that after dyeing, the
lead
can be broken off and the penetration of dye measured. If it penetrates
the
copper then I know the crack is deeper then the tin plating.

Thank you,

Ted

Once you have done your dye penetrant what means/technique will you use
to determine how far and what direction the suspected crack propagated.?
