A friend in the contract coating business said: "... ask why the wire is [teflon] coated in the first place, as only the solder joints should be coated in this situation as the flexing/bending of the wires will cause the coating to crack and flake of

Hi Joshua, No, the adhesive lasts 2 or 3 runs. The adhesive is put on manually as is the kapton. It's a big panel for a flex - nearly 300 x 210, so the operator loading the boards onto the pallet and fixing them (then into a buffer) stays well ahe

Hello, I am currently in the process of purchasing a plasma chamber for the purpose of activating the surface of flex circuits so that they bond more readily. In addition I need to purchase a gas cylinder for the chamber, specifically one that is a

I am sorry to hear that they are unable to help you out too. If you do came up with the doable solution later, be sure to let me know about it too. I would like to learn new trick or knowing which house that can handle such task.

Flexible circuits assembly is different from rigid board assembly. For some manfacturers, fpc assembly are some things more painful because the assembly quality is unstable. Recommend to check and hope these 2 blogs are helpful. Flexible Circuit Asse

I agree, that is not a gullwing lead in the normal sense but that doesn't address the failure. The wetting looks fine unless there is a problem under the lead, which is hard to tell since there is an obvious fracture. That appears to be the edge o

Jinesh, My initial suggestion is you have too much solder past. Please try to reflow a few of these parts without solder paste. Colse aperture, put some tacky flux on this part location and give it a try. I bet you will not see any voiding.

This happens with either old tape, the cover tape doesn't stay sealed on the left side, or is the seal is too far to the right, the knife lifts the cover tape. There isn't much you can do in this case. Your choices are: switch the component into an A

We actually just moved to the Milwaukee area. We would consider that but I have a feeling it will be out of our budget at this point in time. I was offered an attractive price for an Advantis system which is why I am considering it. The AC-30 lightni

I just learned of this and can only find a very small amount of information, and only from one source. I'd like to understand more. Also, they only seem to talk about low temperature PCB like flex. Does it work on FR4?
