For the most part there would not be a lot of change over. There are two primary boards at this time that would be run on the line that also use common components. At this point all but a couple of the pick and place machines we have looked at have t

1) Is there something your design/pcb Engineer can do to lay the array out a little better for the wave (i.e. add substrates, board thickness)? 2)What do you mean by material movement? Single piece/continuous flow. 3) Shouldn't be too hard. You

I'm no guru, but I am among the best that my home state's gotta offer... :-) Anywho.. a Production Manager's definition of cycle time is the time Production Planning schedules the stockroom to start picking materials for the work order, to the time

Hi Willem, you may be better off to study the archives of Universities. I know that at least the Universities in Berlin, Munich and Georgia Tech here in Atlanta are studying the manufacturing process on SMT lines. I was once exposed to a quite compli

Dreamsniper, The optimum contact (dwell) time in the wave should be 2 seconds. Contact band width is a function of conveyor speed. For an example, 5cm of contact band width at 150cm/min. conveyor speed will give you 2 seconds of contact time and 2cm

| Hi, | | Recently encountered missing components problem at the SMT process. | Among 13 chip components from the same part number mounted on the board, only 4 ( located in a same row and next to each other) were missing after post reflow. Checked t

Hey - remember the evaluation of VOC-Free fluxes that I promised a couple of months ago? well, I finally scrounged up the time to remove the propreitary (board name and number) info from the report. So it's ready. I posted it in the SMTnet library
