Thanks Doug,

He is in an auto manufacturing OEM company now and he is trying to learn a new product type.  In telecom we don’t use conductive epoxy so I have never attempted to look into it.  The photo he sent me looks sloppy to me.  They are using needle transfer and they may have a viscosity issue so they are getting what appears to be stringing.  I appreciate your comments.  Thank you,

Hi Russell - I don't know of an industry specification (like IPC JSTD 001) that covers a conductive epoxy joint. We always put the required criteria on our drawings and do not reference any specification.

Hey all,

I was asked a question which is not something I have not dealt with.  But being a nice guy I told them I would post a message on the TechNet and see if any of you have dealt with this.  My friend is building flex circuits using conductive epoxy instead of solder.  He was asking me what the endpoint requirements were for conductive epoxy because he could not find anything in IPC-610F.  I did find IPC-3406 but that does not have conductive epoxy endpoint type requirements.  I am not sure what to call the joints other than fillets but he is looking for that type of info.  If you know what or where the industry standard for conductive epoxy available I would appreciate you letting me know so I can pass it on.  Thank you,
