We do the same when it happens, we only warn the people arround to stay away while the oven is open, or delimitate the oven with a caution cord.

Splicing for Panasonic Machine

Electronics Forum | Thu Jun 20 12:56:21 EDT 2013 | cbeneat

We've only used/seen the manual splicer. However our operators can splice a part in 30-45 seconds. What Panasonic models do you use? The CM/NPM's give you plenty of warning that a splice is needed so the machine doesn't stop.

Selective solder N2 consumption

Electronics Forum | Tue Aug 25 21:12:14 EDT 2020 | stephendo

We didn't use the machine regularly. The dewars would only be good for a month or two whether you used it or not. The nitrogen evaporates and discharges. The first day we forgot to warn afternoon shift. As far as I know nobody had to change their pan

What is the type of this connector

Electronics Forum | Thu Apr 28 09:01:38 EDT 2022 | saberbouras

I have a solder paste fridge; my question is what is the type of this connector so I can use it to attach a warning light. And is it a power source or is it a dry contact relay output?

SMD pad definition may cause solder joint cracking under extreme fatigue conditions.

Thank you for the above information but what I want to talk about is the PCB design aspect. Should there be any warning about it in the DFM?

Cleaning PCBs with a MEMS microphone on it

First check the datasheet to see if it says do not Xray. I have seen tiny microphones with a do not Xray warning.

AOI price

Electronics Forum | Sun Mar 13 23:30:59 EST 2005 | VS

After reflow AOI makes sense because it has the highest coverage of the defects. Problems like tombstone, lifted pins, open solder joints, some shorts and insufficient solder you will not find before oven. I would also not agree with the statement th

Warning "Hitano" caps mis-labeled

Electronics Forum | Fri Mar 16 18:32:06 EST 2001 | djarvis

Anyone using "Hitano" 0805 capacitors please check their values before running. I just got stung by parts labeled as 100nf when they were in fact 10nf. We found five out of fifteen reels in the smd room incorrect, who knows what stores will find. P/N

Re: Vibratory Feeders - USVIBRA vs. COMTRA PRODUCT SUPPORT

Thomas, I just want to say once again that vibratory feeders are a big pain in the buttocks, but better than nothing...and there's only one belt feeder I'd ever consider buying, and that's Comtra's. Don't waste your time with US Vibra's belt fe
