smt common pad 0402 and 1206 package

Electronics Forum | Fri May 06 08:47:05 EDT 2016 | davef

You're correct. This design will have a record amount of 0402 rework for tombstoning and misalignments. Suggest that the pads on each end of all components be the same size in order to balance wetting forces during reflow.

Voiding measure

Electronics Forum | Wed Jul 13 11:57:08 EDT 2016 | ahernand75

Guys I'm looking for a software on the web that I can use to do void measurements. I have x-ray images but unfortunately no software in the machine to be able to calculate void size. Thanks in advance for your support.

Very thin laminate substrate problem with solder printing

Electronics Forum | Mon Jan 30 19:20:45 EST 2017 | jgo

Thanks Rob. I'm not so sure in a mass production environment that using the mount spray and kapton tapes are going to be efficient. For solder paste dispensing, any idea what is the smallest solder dot size the machine can dispense?

Conformal coat material dispensed through epoxy needle?

Great, that is encouraging. I did order a few needle sizes from McMaster to try out when we get the machine setup. What do you recommend for clean up the equipment?

Does pot temperature affects quality of the solder joints?

Is this for a Selective Solder? If so what size nozzle do you run. I run at 315 C most of the time. You can speed up your process time and still achieve good solder fill.

2010 component. and the vacuum pressure is good. using an A14 size tool. tried a smaller tool as well. wondering if it could be the coating the company uses to make the print on the part. maybe its not even or something?

Whats new in 3D AOI?

Great posting. We're looking at AOI for the first time and are trying to understand the pros/cons of 2D, 2D+, and 3D. M, can you discuss what size parts are too small for the Mirtec MV-3L?

Oh wow that is very useful insight! I will remove and check next time we fire up the machine! How did you know the factory size of the intake hole?
