Get a stopwatch & time your functions to see which is the slowest. I am guessing it's going to be the oven, printer (if using paste inspection) or the AOI. If you are talking the average or optimum speed in CPH, that would depend on the type of b

What you can do is perforate the board holding rim by drilling holes of 0.6mm (similar to via's). This will reduce the mass and heatsinking capacity, allow excess flux drainage and facilitate convection heat contacting the board through the holes. Th

Dear SMTnet users, We will make incestment for a SMT Line in near future and the closest machine seems as Advantis AC30-AC72. For more information we are producing DVB's with 30.000 cmp including QFP208, uBGA and needed capacity is nearly 30.000

As we are a low volume shop, the extra handling is not too much of a concern. My biggest concern is if the flux sitting on teh board for a long time (few hours) is going to cause any problems in solderability. My thought is that it should not as it

If you define cycle time as the time it takes to complete one board it is a useless number. What you need to know is the time it takes to complete one board and start the next board. This means first fiducial on first board to first fiducial on th

Servus! I am currently producing Low volume/high mix on Panasonic CM401-M using PanaPro. For optimzing changeover I am thinking about buying the PanaPro DSM module. We use a self made program at the moment, but it sure is rather a "bettering" than a
