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

We have had this problem with one of our machine although it is not a Mydata. We had to reduce the blow off time for these. Our problem was also these same Rnet packages. the part is proabably picked a little off center, then the blow off hits the

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

Without knowing how much you use or what you use it for or what brand and which type, hard to say. In general, follow the Manufacturers recomendations. If you are doing precision work then use cartridges and let them warm up to room temp for a few ho

If no-clean...then this seems "relatively" normal. You could try and extend your peak and duration, however, manufacturers are adjusting their chemistry to survive these normal temperatures (up to 260C and 30 seconds within 5C of peak). You will h

Hi Ahmad, I am using SRT 1100 for about 4 years. I like it but I am looking for something better. What ERSA Model you are using? Is it IR/PL 650A? I do BGA Reworks almost everyday. The most difficult Reworks I have had so far are a very small u
