Ideally the MSL should be recorded on the label on the DRY PACK that you receive the devices in....that's the protocol the device manufacturers / distributors should use to help your goods in and shop floor personnel know which are/are not moisture

I have a QSP-2 which I assume is in the same family as the QSA-30. I compared the diagram that is in the service manual with a board from a 2-C and they appear to be the same. Your best bet would be to contact PPM at http://www.goppm.com. They shoul

Those cards are all different. The c-series stands alone by itself while a qsp2 and qsa-30 mount into a slot. They were all manufactured seperately for each machine. I would purchase a new refurbished one for the 2c machine and forget about the other

I have one pcb which has via holes on both solder pads of 0402 chips. Right now im using type 3 solder paste with 45 degree squeegee. and a lot of these chips are tombstoning. Im guessing with larger particle size of solder paste, the solder will

Hello, Attached is the X-ray picture of a SMT transistor. Please give me your opinion whether this is a good solder or not. From my view, I did not see any solder in the middle pad. I feel it is a production problem. But someone told me unless you s

Melanie: We're with AVFOM. If you don't believe there is solder on the pads, use a beer can opener to pop the component off the board and you will have your answer. Easy-peasy. Who ever told you 'if there is solder, there is voids' in solder connect

I haven't seen that particular fail....but... What was the failure with the M controller? Might try moving your MOT cards around, to see if the failure follows one particular card. If so, you'll know you need a new MOT card. That might satisfy th

After reseating the M controller boards I was able to get further than I had previously, no save status error, and was given an error about the voltage being wrong. During my last run my company had an electrician in to rewire somethings and put a

Unless you have a feeder with unusual vibration that is generated during the advance it seems that the issue is packaging. Try another feeder that has been tuned up and properly lubed. Most high speed turret machines move the feeders back and forth a

Hi Fred Thanks for your advice. That can cause bcoz may be Machine Vibration also. I did not check whether the parts were already upside down before advance.I'll do it in next run. We found that other diodes,see atached pic, were no troble duri
