We've had our share or troubles with this over the years. Flex arrays are the worst. If you machine allows search box sizing, make sure the x/y coordinates of the fids are perfect (CAD #'s only as always!) then make the search box as small as possi

We are having a problem with a 601 pin BGA in that the corners of the BGA are lifting and taking the pads with them. Faults are not always seen straight away so we are not sure at which point the fault is happening. So far it looks as though flexing

It sounds like they are referring to Low-Pressure molding, which was designed specifically to encapsulate electronics. I have seen some products that were processed on polymide flex, and then overmolded in this process. I would start by contacting "

Both Manufacturers and Machine Types are a good choice... Why just these two Manufacturers? Depending on your needs (Changeover times, Board Size, Part Size, Part Counts, Odd Form requirements, CPH requirements, and the list goes on), there might be

Are you really sure that related to my issue? Anyway, in the meantime I experimented a bit with a PVC supplier and now I have a soft PVC that can handle my 185°C (365°F) for 90 Minutes. It becomes a little bit yellow - the previous got cat-black.

I doubt you will be able to get satisfactory results with 0201. 0402 is another story. When doing 0402 projects, we use only electric (MP) feeders and always at the same feeder slots (feeder teach done for each of them). MPF08 nozzle works fine. Also

We can offer several nozzles to assist with the placement of 0402/0201 components in the four-spindle head. We offer the 06MPF along with custom ceramic tipped nozzles. Most of our standard nozzles for this head type are less than $125.00 each. Chec

Also should look at Viscom 3088Flex Ultra if after AOI with 3D capability. The camera optics module has many innovative features, super fast data capture - much faster then Mirtek and KohYoung. Both these companies have taken 3DSPI and turned into AO
