Hi - I'm looking into possible low-end pick/place machines (in UK) for prototype/small runs - taking the next step from plastic stencil/hand place/pizza oven, as my local subcontractors can't offer the fast turnrounds I often need for short runs. Budget: as far below GBP5K as I can get. Requirements are 0.5mm pitch QFP/TSOP/QFN, 0603, but 0402's would be nice. 30-40ish 8/12/16mm feeders, and tubes. Some way of feeding short strips would be good, even if it means sticking them to the bed with DS tape! Paste dispensing would also be nice to avoid stencils on low-density PCBs (not expecting to do 0402 or QFPs this way though!). I Don't mind if the latter involves some DIY fabrication/modification etc. I'm also happy to tackle repairs/refurb myself - I'm very good at fixing things & enjoy a challenge! Speed not very critical, but space & doorway size is limited.
So far the possibles look like TWS Quadra or Versatronics RV1S/RV4S, with strong bias to latter due to depth, and am following up some possible supply leads next week.
A few questions for anyone familiar with these :
Is there anything specific to look out for on used RV1s/4s machines - common faults, wear, unobtainable parts etc.?
How much better is the RV4s over the RV1s? Is it just a speed upgrade, or is it also better for 0402's etc.?
What sort of money would you expect to pay for used RV1s/RV4s and feeders these days?
