Hi James, As my companys process/manufacturing engineer, I set up a program that dramaticly reduced machine down time. Some base numbers; we went from an average of 4-6 hrs set up on our Mydata to setups of under 15 minutes on average and some belo

Hi Erik, looks like there's not much appetite for this debate on this forum. Possibly because not many use them and aren't in a position to confirm or deny what we know. We use our pumps 6 days a week, 24hrs a day so it's a very dynamic proc

1st Consider the time involved with upgrading and troubleshooting! Is it worth it? With prices of PC's near to nothing, it may prove cheaper and easier just to purchase new system! However, Your last Post mentioned mixing of 100 and 133 Rams! Unl

RB, We have a gold finger problem here at our plant. Our kapton tape came off in the wave process and now we have 8 PCB's that have silver fingers. We are waiting on our new A.P.E. SRS-069 Gold Finger Plater. This mircle machine is going to fix a

I have a QFP 160 used on 9 different products that had high fall out for "Insufficient Solder". Basically, a leg or two would pop free when inspected occasionally. This same part is used on different size products, located at different area of each

Hi guys, Have any of you encountered harwin connector M80-647 in the past? Have you noticed any problems with the reliability of the component, solderability and 'reworkability' (thats a new word for sure)? Heres a PDF of the component; http://www.

Hello Joseph, Sorry for the bad news but microcracking is a well known potential condition occuring with the SAC305 alloy. Microcracking is a condition being seen with many joints soldered with the SAC305 alloy. It is technically a shrinkage cavity

Bob, Great theory if you're selling SN100C, but I have to disagree that an alloy being 4�C off eutectic will cause cracks. When a solder joint exits the solder wave, there is an immediate drop in temperature of 100�C. so being off 4�C is irrelevant.

This problem is not unique to China. Second user customers are always challenged to assess machine condition, upgradeability, service history etc. More often then not, candidate machines are located halfway around the world. Further complicating thi

Don, I have experienced the same thing as Russ. The fixed head systems do give the best uniformity (due to no overlap). Both Nordson and Sono-Tek offer fixed head machines that work excellent. I think the Sono-Tek system that Russ is refereeing t
