thomas, why isn't it process control, you cant just think that because you've set up your machine properly ( pot temp, wave height, pre-heat etc etc )that everything is going to be ok, there are other factors that you wont find with wave riders or

You are not wrong in monitoring the Product (your really not monitoring the process). This methodology is valuable if your process is unstable (SPC is used to stabilize process). There is value in "real time" inspection of a process's product as lon

Thanks pr I know what you mean, and just to let you know, you can turn the over head one off and get one for the center nest. Will be more than glad to tell you how to turn off and turn the center nest one on. And just to tell every one else, were

Hi I thought that I was the only one that thought that was confussing. Have almost never had any one mention this one. When I was a field engineer for mpm, people would say something about every thing being backwards and then they would just accep

We have two APS Gold ovens and are acheiving an accpetable Lead Free profile. We still have to further qualify board widths/sizes to determine what are limits are and still be within the profile we need. For the most part you need more zones/longer t

We have this problem for a long time. It happens to 3 new Mydata MY-9 machine. When pick and place resistor array 0408 (different value, top and bottom side), the solder paste in the middle two terminals missing occasionally. Thought it's because noz

Hi, I looked at the pictures and it looks as if it should be a straight forward solution..but obviously not. I would focus on the stencil/print more than placement machine. The placement machine simply places the part on the board!#(just one thing

I have seen this problem on Mydata machines before. I am very sure that your missing paste is being caused by the placement machine. Check these things : 1. There is a small white check valve on the pressure side of the vacuum pump. Make sure it is

How does the mount plane change if the surface of the board is located in the same place every time ? For example: If you put 2 boards side by side on the Y wagon : one board measures .020" and the other .200" the surfaces of the boards are going

Hi, I know this is not exactly SMT related, but it's the right group to ask, but we need better powered screw drivers, as the electric ones we have the girls are having difficulty screwing in the plastic screws we use. Can anyone recommend good sc
