peter, define what you class as SPC for these area's, or do you just mean looking at the PPM or DPM levels? John

The consumables monitoring option totally disappeared from one of our printers. It used to show the level of paste, paper and solvent and now that window is totally black. I was wondering how we could get that option back onto the monitor. Thanks in

Similar issues arose for me in cases where the contact pads of components were located below the solder mask level. Ordering a thinner stencil might potentially solve the problem.

Casimir: Let me expand on something that I said in my response to your thread on ionic testing. Generally, no-clean people don�t use ROSE testing as part of their process control, because the ROSE test is essentially washing your board in DI/IPA �

Victor, here are a few more elements of information to answer your question. Both the temperature and relative humidity on the manufacturing floor have a significant impact relative to the rate of diffusion of moisture inside a plastic package and t

I've used an on-axis camera lighting for other components with a good deal of success. (But not for CGA's in particular) I would think it should work pretty well for a CGA application. I've done some pretty odd looking parts with this type of lightin

What does the reflow profile look like , the question I had was surrounding the higher reflow temperature and the max temperature that lowest thermal mass components will see. Some other questions that I had were surrounding the components , what of

Casimir This is not an easy subject. How did you process the test pieces? Was the flux used correctly at the required and recommended level? Did it see the wave properly? I am not an advocate of no-clean but we do have customers who coat over no-cl

Hi Jeff Actually it's not necessarily Signal to Noise Ratio or even RF circuitry. All no cleans leave behind residue by description. This residue can affect RF or other high frequency circuits in a number of different ways including SNR. Very high
