We dislike having to use the horizontal scroll bar [er whatever it's called] also. Large images in a posting cause the box used to reply to that posting to be shifted to the right is an nother peculiarity that could be improved. [Probably, this isn't

Reflow soldering de-ages the capacitors. Two things may be affecting your testing. * Capacitance measurements are often erratic during testing for about 10 hours after de-aging. * Test limits should be set so that the capacitance value is within the

Stumbled around in the data management section for a while and found that the board origin somehow got its sign changed from -ve X value to +ve :o/ - Is there any way to change the colors on the display. Someone has made some really bad choices (blac

DEK Infinity-Does anyone have any information on why the automatic screen changer would load the same screen in a different position everytime you load and unload? We constantly have to do a search step for the fiducial and most of the time it will e

The fact, that your Hydra head goes up and then starts moving slowly, means that it didn't find the limit. Since there are no mechanical obstructions and you swapped all the boards, the things to look at are cabling. Double check the ribbon cables fo

The question is, the motor is working or not? Moves, does anything? Seems to be endswitch not working if moves and you heard beaming sound - like motor moving but its on mechanical endpoint. If I were you, I bet on a limit switch is defective under

Well, the precision glass is for upward looking camera's. It essentially is a "perfect part". Vapor deposition lithography on glass (for Cte stability)....basically the part pattern (or part fids) is compared to its target location (same pattern on

Mario, Thanks for your response. We are building a leaded assembly with hot air leveled Sn/Pb pads on the PCB. In one case the component is a 7.5X5.2X1.8 wire wound ferrite inductor with Au/Sn leads. The second component is an 0808 Tantalum cap,

NEITHER AXI nor AOI are "stable" or "repeatable." If your false call rate is zero, then you've basically rendered the machine an expensive conveyor (ie it's passing everything 'cause you've opened the limits too much). You can *try* to do a Cpk or

Thanks , Reese.Yes , I check the capacitors with C-meter.When measured with C-meter , all capacitors are OK - +/-10% of the value. I can not underst?nd "Note: This is not a summation). Y5V -- -20% of nominal value, -part tolerance, -machine toleranc
