I used one on SMT at a previous employer. Make sure that you have 3 zones of preheat. Make sure that your operators are trained. The airknifes are extremely difficult to set up properly. Don't use them on high mix lines. We didn't need them once

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

I have read all of the previous threads and have found it very hard to believe what I am hearing. The idea that AOI is not needed on your production line is like running a marathon without training before hand. You can only expect to get out of an
