We call this the "orange stick test", but who's coloring? In preforming the test, you're supposed to use a light touch. Unfortunately, it's difficult to calibrate a "light touch." So, operators often end-up using too much force when probing or usi

Are there any write-ups anywhere? My boss wants to show a customer a write-up. I"m checking IPC specs but havn't found anything. I think almost everyone does it but is not a published standard test. I hope some organization has written it up as a st

Sounds good. Id like to add that we are not intentionally freezing the paste. Its supposed to be chilled only. I think the t-stat on the fridge is malfunctioning causing the freezing temps. I have new paste coming in today. If things look better I ma

I forgot to mention one key detail. This goes against the typical thought process when confronted with the above mentioned dilemma. The stencil depth/size must remain at 29". You must lie to the machine and pretend to have a 29" stencil with a 5" fra

I hate to start to drag this off-topic, but I just had someone here interject that perhaps going to 20x20 and using a different adaptor would be the way we should go, due to the cost difference. Can you (or anyone) quickly identify a few reasons why

I would imagine you would end up stressing the stencil, as you will be continually contacting the stencil in different places. Also damage one stencil with four images on it, and you will end up waiting for new stencil to arrive. You then have four o

I'm really getting a lot of fun, at leat Rob has some good points matching technology and humor. These kind of questions should be out of the forum, what I suggest is first to do some research previous to make any GENERAL questions about what SMT pla

George We're not sure about the application of powder flux for original poster to this thread, but a common application of powder flux is in brazing. This powder flux can be either metal bearing or just flux. As an aside: Soldering and brazing are

Has anyone experienced electrical shorting between adjacent leads of a ceramic hermatic sealed IC? If so, can you share root cause and corrective action? The shorting appears to be in the glass frit seal itself but the failure mechanism is unknown. A
