Been working with CM's since 2006, we've had 2 lines of NPM's for the last 4 years. I like the NPM's, but the CM's have been a work horse. We have gotten our monies worth:)

Your thought about cheating like mad expresses what was going through my mind when I read that line.

Hey there, Can you take a photo about your machine? For example my machine has a stencil-like blade only.

As Dekhead has said, sounds to me like you have the wrong setting in your screen choice within the program, is it edge or centre justified?

Robl, I like this underfilm. Do you think you should place it in the middle of the part? I am curious if they provided some advice to you as how to use it.

You can also consider the very old simple method with decreasing the reflow zones on the bottom side with 10C. Sometimes when it is marginal issue like yours....you could be surprised.

Sounds like bent rails. Do you have a laser pen you can shine down both sides of both rails to see if there is any curve?

Hi, Thank for reply it. I'm exporting it exactly like that. But the results are as I explained. Question: Is there another procedure to try?

Try to measure the profile again by datasheet..with the result that you will reduce the temperature in the areas below...increase the upper temperatures as needed according to the properly measured profile...I hope you can solve the problem like this

It's unlikely to be a reliability issue. It looks like tin oxide. Nothing to be too concerned about. Otherwise your process controls sound robust.
