Our Panasert MSH is randomly mixing up the parts placement. About 1 in 10,000 placement will be a wrong part. The wrong part may be any other part present on the feeder carriage. A chip resistor 0805 may be replaced by a minimelf or a sot-23. It is

We have also placed BGAs with IP-2, with no problems. Ours were 50 mil pitch PBGAs, and as Doug says the perimeter is more than enough to place the part. We have only placed from matrix tray so far. The ONLY problem is the center array, for parts tha

We are using a mixed technology process with mostly through-hole parts plus some SMT IC's on the component side and some passive SMT parts on the solder side. We do not have a proper wave soldering machine for doing solder side SMT (double wave or o
