MS05000 Budget Logic Analyzer Probe Set Design
ve2mrx:
Hi everyone!
I'm an absolute newbie at SMT but have plenty of experience with PTH, how would you rate the difficulty of assembly, any "must haves"?
So far, it needs an appropriate soldering iron and "no clean" flux. Anything else? Microscope?
It would be a nice addition to my MSO5074, if I manage to assemble it...
73,

I do all my work under a microscope but my eyes are old and worn out. A good pair of tweezers is essential but forget about plastic ones, they melt. The design is deliberately 0603 and ICs with legs to make it hand buildable, U8 is the smallest pitch so I would put that down first.
Believe it or not, I use a fairly large T12 'K' soldering iron tip that looks like a small modelling knife; you can use the sharp end to get to tiny points or flip it around and use the flat edge for soldering wick. I like it because it has great thermal flow.

Hey everyone, I am busy with home schooling and don't have time to write much. But my order from DigiKey showed up a few weeks early, due to kids responsibilities, it took me a week before I could work on it, I built one scope connector board, and 4 (2 x 5V, and 2 x 3.3V) input boards.
I will provide a writeup when I have more time this weekend to capture lessons learned as a supplement to the excellent material Gandalf_Sr has provided.
I hope it will be helpful those who are about to begin the build shortly.
As far as skill required, 0603 size components is not something you would want to solder without magnification devices, so it is definitely more care required than through hole. I will share the tools I used in my writeup later. I don't do 0603 on a regular basis either, at the end, I destroyed two LEDs, both due to reversed polarity, mistake on my part.
Stay tuned.

Everything has been delayed horribly due to virus reasons. I'm thankful that they came at all.

Me too, I don't really care about money which I would happily refund it's just frustrating to go to all the trouble of packing up PCBs and paying $8, $10, $14 to ship them and find that, more than a month later, many haven't arrived.
