Bought some new flux to try from Amazon - M G Chemicals Flux Paste. Supposed to be as good as Amtech stuff but heck, it's not cheap.
Bought some new flux to try from Amazon - M G Chemicals Flux Paste. Supposed to be as good as Amtech stuff but heck, it's not cheap.It is good, I use it but it does leave a nasty sticky residue that really takes a lot of cleaning with IPA unless someone knows a better way of cleaning it up. I know it says "No clean" but it doesnt look nice if you leave it behind afterwards and just attracts dust etc to stick to it which cannot be a good thing can it.
Agreed. I would make the effort to remove any residue regardless even if only for aesthetic reasons.
I do have an issue with these syringe applicators, not too easy to control the flow. I'll have to make/buy some sort of dispensing device which offers more precision. Do you know if this stuff reacts with any metals or seal materials directly? I could use stainless steel to make a reservoir and perhaps Viton or PTFE seals in a pump mechanism. There must be a commercial applicator but I'm guessing it would be a prohibitive price for hobby use..

Just won on Ebay a nice nixie tube meter that I was not initially drawn to until I noticed that it not only reads up to 1G ohms but also has dedicated uA and nA ranges as well so nicely extends my measuring capabilities.

I take a simple alcohol wipe and work it on the board with an old tooth brush. Cleans up pretty good for me.
Sounds like fun In Germany ants are not that often. Found once some in the woods: https://goo.gl/photos/Xd2BzshRVVme1f9L8
but they were on the list of endangered species (they are probably Formica polyctena), so I couldn't take some for my ant farm, and they need winter rest as well, which would be boring.
This morning I received my most expensive package, everything is custom except the solder paste.

The membrane keypad - did you get just one made? Was it expensive?
I've got another project that needs a membrane keypad here - but they are so expensive to get made in the UK.
