Depends on the actual requirements of the machine & the skill of the operator, but for that sort of money I've seen Juki 570's with a stack of feeders, Versatronics RV4's, older Mydata's, Samsung CP30's, Essemtec, Philips CSM's etc. I even once bough

myu, Is using a 0.6mm stencil wise? 42.5 X 42.5 has two models, the 1mm pitch has 41x41 array with 1657 I/O and the 1.27mm pitch has 33x33 with 1088 I/O. For a typical c-cga with 1.0mm - 1.27mm pitch, may requires a 2mil stencil, 1.0mm pitch gets .

Are feeders included? Otherwise, the MS 102/132 sell even for lower prices here in US. Add shipping and training and you get to the same result. Juki, Contact and Quad may fall in the same price range, but spare parts and service tech availability wi
