Hello Bill, As I mentioned in an earlier thread, I was not familiar with the PAM system but have since been given a quick run down on how it performs its measurement routine. It is an acceptable way to measure and optimze Fuji chip shooter performanc

This touches on one of my pet peeves. Management types demand something, that is not feasible or practicle. So the manufacturers put something together to pass off as what was asked for. In this case a way to put hard numbers on what a machine can

Nice pix. The pebbly texture that you're seeing is aptly called "orange peel". Temperature appears to significantly influence the appearance of solder spheres during soldering. Indeed, when the reflow temperature is high, tin continues smelting long

72 different part numbers, 53 being 8mm, remainder being 12-44mm and 3 tray. It may be low but anymore than 100 and you give up throughput because of feeder locations. And thinking about it, 70-90 is low for a low volume high mix line. I guess if I w

Hello Stefan, Thank you for your reply. I see now that manufacturers are aware that this kind of thought process is necessary for the bottom line profit. It is also true that one can be "seconds wise and minutes foolish" in the process. I read with

I am running A Universal Chip shooter 4792 HSP machine. I would like to know the optimum speeds this machines can be run at. I am currently running the machine at a tact time of 18S-14S depending on the types of components and the complexity of the b

There are many variables that could cause components to be misplaced. Using the overall tack time reduction is in reality putting a band-aid on a larger problem. Are your small components shifted as well? ( 0402,0805 tec) Components "twisted or off

Yukim, First off..sorry I haven't responded to this already. I hadn't noticed any responses in a while. I would be very surprised if you have worn nozzles in a two year period, but it is possible. For instance, if you have been running with an extra

Murtuza You have recieved loads of good info mainly all the preventive maintenance to be done. But can I ask was all of components placed twisted or just some when machine was run at full tact time 0.12s, I ask this as I run a 4791 and if its only so

AlCapone: Consider determining the responsible party according to their ability to deal with the complexity of collecting and analyzing the information required to determine your process capability index. For expample: * Reflow oven: Fairly simple,
