One more note on this. The techs tell me that the main reason for the PV immediately matching the Set Point is that the software is in "Edit Mode". This is a mode that allows one to iterate the software without the oven running. That might also ex

Greg: Heller 988s are good, solid, basic reflow machines that will turn paste liquid for 85-90% of all applications. I'm not sure what you mean by "is it comperable to the larger heller with a slower rate?" But, yes it will need to be run slower t

Hi,, My doubt is regarding to the Reflow Time, I mean, in a 5 or 7 zones oves, how long the board should stay inside the oven to complete the soldering cycle? 4 min, more, less...Should I keep low temp until peak for a long time or high temp in shor

Hi. We have changed our produktion from high volume to medium/low and have to start hunting change-over time. We have a lot of products with two sides and the settings of pins in the DEK 265 and Fuji QP242 machines when running b-side takes to long t

Are industry time standards based on actual time...or money? From a start to stop time on a multi-machine SMT line our time is well below standard. (Our company uses industry standard (I'm told) based on .09 sec. per placement.) However each pick an

Hi Peter, We're typically seeing 60% on the average subcontract job, but on high volume, high density & well laid out boards we are seeing up to 95% on our chipshooters. The things that usually kill the speed for us are: multiple circuit panels (3

This is highly dependent upon your board, vision inspection, part rotation, part type, layout, number of P/Ns per (1 pers or 100 pers) feeder layout, optimization, nozzle changes, etc... all have significant impact on placement speed. I find if you

Hi Peter, You certainly have a selection of kit. We use 2 CP6's & 2 GSMs per line, and that balances pretty well (sometimes one of the fuji's is idle though - but we can live with that). When we had S20's we found 2 of them roughly kept up with a
