Hello everyone. I have around 1200 ICs that needs reballing. I don't plan to tackle these ICs myself. Therefore, anyone know of any companies that have a good/quick/cheap reballing service? And can anyone give me a ballpark figure on the service

I would appreciate comments from anyone familiar with Fuji CP6's and CP6E's. Essentially, I would like to understand the important differences between these two machines. Considering that we use FujiCAM as a programming tool, does a CP6E require a

The E has a different x-y table setup, i seem to remember the CP6 having rollers and cams to control the z table height, the CP6E has a belt driven z axis. Also i think the CP6E is slightly faster, 44K cph against 40K, still just program it as a CP6

Your thinking of the FCP6 vs. CP642. The table on the CP642 is different from the FCP6/FCP6E. The speed for the machines is still rated at 40k cph (0.09). The differences from the FCP6 and FCP6E is the Safety Circuits and a few other electrical dif

i think a more important issue here would be the reduction ratio. as LF solders have a higher surface tension, they do not flow as well as their leaded counterparts. therefore the stencil design may have to be changed (hence a new stencil) if the red

Good machine! Just like most part libarys don't let the operators change part profiles. Haven't seen it place 0201's but 0402's have no problem. Tape splicing for the feeders is a problem. The eject wheel gets jammed with anything other than splice t

Something unusual happened yesterday, we reflow soldered two boards with white silkscreen legend, and they came out of the oven with purple silkscreen legend. Not tan or brown from overheating, but purple. The boards were reflowed on their normal pr

Epoxy inks tend to be more resistant to discoloration than the acrylics that are used more widely now. The acrylic-based inks vary in their ability to maintain color after heat cycles. The technical data sheets from the ink supplier should indicate:

We had the same issue on a batch of boards and the board house concluded it was because they did the sikscreen before the imersion gold. (which was done out of house-which is very undesireable). I never knew if this was really the case but thought I

Do you really use it that often in your facility > that this would actually be a good cost-cutter? > Maybe there are some different prevention steps > that need to be implemented. Safety glasses? I flush the stuff every 4 months as recommended.
