I am looking at buying a pick and place machine to assemble the circuit boards we make.
Most of the boards are small (2 to 10 square inches), most are 2 sided, and have maybe 20-50 parts per side. I use mostly 0805/0603 chips, SOT-23, SOD-123, SOIC-8, etc. I have some microcontrollers in a QFN-56 or QFN-68 package (0.5mm lead pitch). The biggest parts are stuff like TQFP-64. I generally make about 500 boards a month, which works out to 20,000-50,000 placements a month. So I don't need anything super fast. I would like to be able to do 0402 parts however. I also do some unique parts like Luxeon Rebels where I need to be able to adjust the pick location and the head movement speed so I don't drop it, so the machine must be flexible enough for that sort of thing.
I am trying to not break the bank... maybe the $10-15k range.
I've bought a few machines before with bad luck... so whatever I get, I just want it to work. I don't mind doing maintenance and some repairs myself, but I don't want someone else's problem child that they are unloading. It seems the machines I bought before we just this - someone else's problem child and all needed tons of tweaking to get them to run for a solid few days.
Is my $10-15k range reasonable? What would be a good suggestion in this price range? Any idea where to get such a machine?
I talked to QC Electronics... they say they can sell me a late 90's used Quad IV-C for that money, with maybe feeders, and the machine will be "completely gone through and checked out". PPM said for $15k or so they can also sell me a Quad IV-C that is refurbished to as-new condition.
I know nothing about Quad machines. I like that the Quad runs on a dos software, so I can back it up and I know my way around DOS easily. But I would much rather have a point-and-click windows interface... but maybe that is not reasonable.
There are a lot of machines on eBay, but they will often say they were taken out of service a year ago and sell them "as-is", and I'd never spend $15k on an as-is no-recourse machine that nobody knows if it works.
Any suggestions?
