What kind of "auditor" is this? Who does this auditor work for HP or CR Technologies? Maybe the auditor can quote 'chapter & verse' of the IPC specifications that state: * Inspection of any type is required to assure solder print processing repeata

Why measure solder volume? I believe if one understand the process well enough, the effort should be spent on area that will gives better indication of your solder printing process. From my personal experience, a lot of auditor knows little of the pr

We based ours on the type of paste we use (stencil life) and not so much the machine. Then we coupled that to what 'true' conditions we normally see in our plant, and determined that under these conditions Max & min) our printing process should be g

How could you know if your printing process is capable or in control if you don't have a print measurement tool? You�re correct that you do need a measurement tool to determine if the process is capable or in control. A $1.5k microscope and some g

I agree with Evtimov that sticking with the J-Std-033 is preferable to creating your own procedure at a different temp, especially if you need to pass an audit since the auditors will compare your process to the J-Std. My understanding is that oxida

Hi Nightbull, here�s daybull speaking. Yes the same question for me, what kind of auditor was that ? What I do in an similar audit situation is simply pointing to, if existing, an obvious lack of performance in certain processes depending on my humb
