Dror, If I understand your question correctly, you would like to know what the operators should be doing in what priority during setup or changeover? Simply stated if you are doing on line setup due to limitations in feeder quantity or manpower avail

We have developed a Cost of Ownership model that incorporates a number of factors when considering SMT equipment. There are the obvious ones like maintenance costs, labor costs and shift patterns. We also considere utilities, quality, set-up time a

I've always hated using machine specs....they're always best case scenarios, and nearly never capture actual through-put rates. Personally, I don't like using first-piece rates, either...unless you're looking for worst case scenarios. Usually, the

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

Just to comment on the quad equipment side......The QSA-30 is also obsolete but you can use the same feeders on it as the 4c. The setup time would be the same but the speed is quicker (i think around 10k cph). If I were in your shoes....i think i wou

I am currently looking for a quicker more efficient way to kit our parts from pulling to the carousel to organizing feeder locations on our SMT equipment. Currently we pull our parts and place them on a rack in no particular order. (we have too many
