Russell,
Unfortunately my customer has not approved wire repair because it falls under the category of "medium" conformance (see 4.2.4) However, IPC-7721 does state that it can be on class 3 products if the lower level procedure can be demonstrated that it will not adversely affect the product's functional characteristics. I am assuming though to prove this some additional testing other than a functional test is needed. Please correct me if my assumption is wrong.
Thanks,
Rich

Rich,
I have never played with any of the film adhesives. My first question would be is: are you allowed to use repair wires on your customers product?
If so, second question would be: why not use a repair wire that reconnects the leads and the traces. You can size the wire to carry whatever current you need.

Subject: [TN] IPC-7721 Conformance Levels
Good morning everyone,
I am looking for some information on the "highest" level conformance (see pg 2 of IPC-7721) for a Class 3 product. I am currently faced with a situation in which we had some SMT aluminum Electrolytic capacitors shear off the board (and took the pad and trace with it). Boards are about $800 a pop so I really don't want to be scrapping that kind of cha-ching. I am looking to use section 4.2.2 and section 4.7.2 (SMT repair with film adhesive). I see that PACE makes a ThermoBond Cir-Kit with film adhesives but I have not had any personal experience using this one. (I am used to using the epoxy type repair kits). So before I go out and spent some $$$'s, I was hoping to get some feedback from the group on their experiences with film adhesive repair kits or any other film adhesives kits that have worked well.
Looking forward to your feedback.
