A few lifetimes ago I went to a seminar on reflow profiles. The speaker emphasized more than once that the cool down rate is important. Someone asked him about controlling the cool down rate and he acknowledged that you can't. And IIRC it was an ove

I work with small batches and this is what I do. However I don't do it because of the paste. Instead I do it because I am the sole operator on the line and I want one process finished so I can keep a better eye on the others. I specifically work with

I don't know this exact machine, but it likely has similar logic to some other Samsung machines. The E-stop buttons have TWO sections. One shuts off the "main start" button, the other informs the computer that the button has been pressed. If you d

Just curious if anyone has ever used an EMF meter? I have used a static field meter but that is quite different. I have had hearing aids that had a switch that switched from an audio mike to a telecoil that would pick up the EMF from the phone speake

Hi Smitty, I am currently using Manual Lock Red-E-Set, and never had problems with damaged components. Although at my last workplace, we used VarioGrid, and encountered same problems as you. I suggest checking the pins on the support tools(s) you h

I don't completely understand your set-up, or what you mean by "in parrallel", but here is what I do. If you mean to have the 3 machines each build part of the board, this is what I do. I have two machines in one line and I split the job between the

We use to have to replace the "dog" tube when it got rounded out or worn a little. If you you already cleaned it and can see the red light going off and on when you gently push up on the nozzle it is just not seeing in time and it gives the nozzle c

I've had the most success in a check/double-check set up. Most people will tell you that it's labor intensive, and they're not wrong. However, I suspect that those people have never had to manually change two components on a thousand boards at a sh

It will be tough to get a good line for that cost. You might want to start by looking at Mydata and Juki for the machines. Ekra for the screen printer and Heller for the oven is where you might want to start. If you have not already you might want

I can't emphasise enough. Get good reps. I'm sure I'm not the only one that starts a search for a new product by asking a few trusted reps what they recommend. The product has to be good but the reps are the first place we start. And be prepared f
