Check with your UIC sales if your machine can be upgraded to UPS+ 6.2.2 sofware. They have upgraded the vision system so that it can process these kinds of parts.

Hi, We are facing a complete new package type for us in our prototype production. RoHS LGA 36 Land Grid Array with 36 so called pads instead of bumps underneath. It is totatlly flat. This component is only 6.5 x 3.5 x 1.6 mm and we recieved them in a

We have a dead one too. :( They're not cheap. Do you know what's taking them out? I suspect a shorted cable is what took ours out.

I did my directory by using the Fuji Part Data Directory. You can request one through Fuji and have a copy for all programmers. For instance a 3216 resistor is named RECT3216060 or your electrolytic caps ALEC4343540. Hopefully that is what you are as

Not a fan of bench top, as you have to load the component and the board into a fixture, then unload afterwards. We trialled with 3 linked ones for some complex boards which worked well, however it was not cheap, and not that fast. I'd look at sel

Solder iron robots tend to miss solder joints from time to time. The wire feeder systems are the key to these machines. Most use the edge of the board for alignment is another reason they miss. If you have SMD close to the thru-hole, the robot may
