Ryan, Another option to look at would be ultrasonic cleaning if your boards/process would allow it. Automated multi-tank models with wash, rinse and dry capability are available for larger throughput. Typically both wash and rinse tanks have ultra

I have an ap-25 and wish i had gotten the UP-2000 instead. How's that for an answer? The main difference is that the ap-25 uses linear motors and air bearings, whereas the up-2000 uses ball screws. The linear motors are faster, but the whole thing i

I think right now there is a comfortable buffer built into our process. If our pnp were 50% faster I believe that buffer would be cut out of the equation, so while I think it would be fine on most of our builds, I believe there would be builds that

Hello Spoilt... Yes it's true about the kitting being important but we also offer a component tester/verifier option for our system. The components can be tested for each insertion if you wish. The machine will not allow a component to be inserted

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

I've successfully refrigerated a pasted board, and placed/reflowed it the next day with minimal issues. Me too. I'm looking for more than one day. > You might want to invest in a stencil cleaner Tried that. They do not work on the high-aspect ra

Well I stand corrected; we tried re-printing mis-prints on Friday with our auto printer and indeed it worked out very well. I did let the paste dry up a bit on the mis-printed board while a few others went through to try and prevent smearing as it re

Most reflow ovens will heat up faster than they cool down when changing from 1 profile to another. Run your Pb products first then change over to your Pb Free products. That way you are going from a cooler profile to a hotter one. Going that direc

Solder flux and solder paste deposition is a standard step during the chip attach and sphere attach portions of BGA and CSP assembly. A technique called ultra-violet fluorescence intensity mapping (UV FIM) has been introduced that allows flux measure

Need more information. BUT if your strictly considering just the paste change. I would imagine your changeover would be little to no different than changing to the second board if you were using the same paste. Maybe take extra care cleaning your sq
