Hi Reese, What kind of shop are you? Do you have a dedicated line or are you re-configuring your line often? Do you have a high product mix? As others have mentioned, the Mirtec and the YESTech you currently own are much easier to program and use th

For pick and place, I have worked with the Zevatech machines and Philips machines. Both are great machines. The Zevatech will give you greater speed and still offer great accuracy and repeatability. Don't let the belt drive stuff scare you, it sta

50% reduction in time. One draw back, the availability of feeders... You need 280 feeders max to change over a max capacity of 140 feeder machine (or a variance of a product mix vs. part numbers); then there's 8mm, 12mm, 16mm, sticks feeders that c
