Startup current depends on your configuration. ours dose zones 1,2/ 3,4/ 5/ 6,7 last i checked it pulled about 40-55 ish on start up and 25-35 during run. our profile is a slow ramp till 170c then a fast ramp to 285c 280c(last 2 zones). 1707's

We have the same issues with QFN's on reels being cost prohibitive, so we also have to deal with tubes. We have had some luck with using a modified tube ran down (almost to the pick position) the channel of a belt feeder, assuming the QFN tube/channe

I have two new quad feeder bases and feeders (my machine came with none to start, and I can't find any electrical information on them. I have 4 pins at the each end (total of 4 connectors. And are in a 4 pin connector which looks identical to a sta

We have been using a selective solder system for all of our automated LF through hole processing to this point. It has served us well but volumes are increasing and we are getting ready to pull the trigger on a full size wave machine to handle the l

Figured out that you have to press Ctrl & Enter to get this screen to come up. Also, to remove the LCS, you need to remove the "Y" cable to the left of the control box in the bottom of the Topaz X. All works well now, but still can't get it to load

Thanks for your input. I heard about the component size from someone else as well. They said if the component is greater than 8.4mm, it will not load another component next to it on an adjacent head, which is only 16mm away. The PLCC6 LED's are 5

In a previous life we burned bar-codes on PCB with a CO2 laser. Initially we placed a small white epoxy pad to burn the code into. After some experimentation we found that we could eliminate the epoxy and just burn through the soldermask and the un

We currently have 2 M1 systems. Our false call rate has never been has high as you suggest. There is something wrong with your program and/or inspection algorithms, as you probably already know. You should be somewhere between 1000-1500 vcpmo (fal
