There is nothing worse than having a multi-thousand dollar machine destroyed because of a few minutes' negligence. text/html 2009-11-06T15:28:06-05:00 phillip torrone http://ladyada.net/wiki/mdcpickandplace/equipment?rev=1257539286&do=diff Budgeting for a pick and place This is going to be the toughest part. You'll need to justify the expense of having a pick and place since it's not really something you want to have around just for looks. The cost will probably run you somewhere between $25k-$30k depending on the options and feeders that you get. It's obvious that it can save you time, but will it be worth the expense? text/html 2009-11-06T13:48:06-05:00 ladyada http://ladyada.net/wiki/laserinfo/start?rev=1257533286&do=diff This is the base page for the Adafruit Laser Information wiki If you want to just view the data, go here to the laser info page For more information about Adafruit Laser Services, please visit the ALS website So far these are the pages we have: * Equipment * Supplies * Maintenance * Materials * Settings * Providers * PCB Stencils text/html 2009-11-05T22:03:02-05:00 ladyada http://ladyada.net/wiki/mdcpickandplace/jellybeans?rev=1257476582&do=diff ??? Jellybeans are the cheap and ultra-common parts that one uses for electronics. Like 10k resistors, indicator LEDs, or 0.1uF caps 0603 Useful for boards with limited surface area. Not as small as 0402, but can still be hand-soldered and they use standard reel holders (0402 reel holders are more expensive). These may be harder to hand-solder than 0805, though, so if you are also using the components for hand-soldering and only want to stock one-size, 0805 may be a more appropriate 'gen… text/html 2009-11-05T10:05:46-05:00 ladyada http://ladyada.net/wiki/mdcpickandplace/download?rev=1257433546&do=diff Manuals The manual for the software for the Luna EXP NX: The manual for the software for the Luna EXP: Spec & Data sheets The spec sheet for the MDC Luna EXP NX (stepper motors) The spec sheet for the older MDC Luna EXP (servo motors) Other docs Our MDC showed up with loose "homing dots" - the brackets on either side of the bank 1 feeders.

You'll need more than just the machine, here are some important accessories to drain you wallet Compressor Considerations A pick and place needs compressed air to operate. At the least, air is used to vacuum pick the parts from the trays and reels. For the MDC it is also used to control the adhesive/paste dispenser (if its installed) and the hammer that advances the feeders. text/html 2009-11-04T16:29:16-05:00 ladyada http://ladyada.net/wiki/mdcpickandplace/troubleshoot?rev=1257370156&do=diff Bad USB cable When we first started up the software, it didnt display the huge red "ON LINE" button and said it couldn't find the "KPS card" due to a bad USB extension cable.

If you want to save money on the PnP (~$2k), you can just use an old PC or buy your own. It needs to have PCI slots though because the IO card that controls the machine plugs into it. The power supply supplies power to the motors and pneumatics.
