Hi all! Got a question for you guys:) I'd like to measure if the grayscale of an AXI is stable or not. How shall I do it? Should I do a process capability study or is the X-bar chart-method better? Or is there a third method that I should use? What

NEITHER AXI nor AOI are "stable" or "repeatable." If your false call rate is zero, then you've basically rendered the machine an expensive conveyor (ie it's passing everything 'cause you've opened the limits too much). You can *try* to do a Cpk or

Just what was said plus 3. the number of solid tabs can be increased for stability.

Thanks for the input. I read that paper. I'm not convinced the Pb stabilizer and bath MTO's are a cause of the Black Tar defect. If that were the case, given the history of Pb stabilizers and ENIG, I would have thought that there would have been many

The temperature is measured with a Pyrometer. It measures the spot that is being heated with the laser. As the surface heats up, the laser power is decreased to stabilize the temperature.

Inductive effect is the electron attraction force between chemical moieties. Inductive effect in flux activator would stabilize the dissociated organic acid, thus enhance the acidity, therefore increase the flux activity.

Can someone suggest what material I have to use to protect components by electrical discharge on ptfe based boards? It should have high resistivity, thermal stability (-40 +70 'C),perfect adherence on ptfe... Many tahnks

We have been told that we should bakeout FR4 boards prior to assesmbly - i gather from your discussion that you disagree - any details will be sincerely appreciated. Regards.

SMTnet will be down for a software upgrade at approximately 10:30 AM EST this morning for about 30 minutes (although probably less). We appologize for any inconvenience this may cause. The software upgrade should alleviate some of the performance a

Hi, I would like to have information about means to improve the stability of a SMD-Line: indeed the variation of the daily performance is too important (between 50 and 250 ppm). What is the solution to reduce these variations? climatisation, other re
