Either solder it down properly or use glue that is strong enough!

They used some sort of glue to attach the quartz, but it either softened over the years or it wasn't strong enough at the beginning. Tapping the device strongly on one side (as might happen if the user gets annoyed) made the thing move out of center - permanently.

Postscript printing is not encouraged, use 'plot' instead. Build: (2011-07-08)-stable, running on linux.

Maybe useful as well. Maybe...

I have a couple of these chips, both in SMD and DIP. Quite often I shy away from playing with them due to the 'hassle' of setting them up. Maybe this will help a bit. The boards are just 32x32mm

The backside of it.

Board-shrink to just 50x50mm. This will make it cheaper. Although I like the looks of Rev 0.1 much better, cost cannot be neglected.

This should be useful for me. Floating inputs suck.

It's not bad, but it's mostly alcohol. Leaves a white residue. I use(d) it for adding a little extra flux when the rosin core of the solder wasn't enough. Not suitable for rework, as it evaporates too quickly.

I'll try to use this as a position sensor for one of the brake cables on my bike. Thought of strain gages or hall sensors to sense the tension in the cable, but this seems to be the cheapest way to do it. Position doesn't really map 1:1 with tension (= braking force), but it will be close enough to use it.

Now this stuff is GOOD. No smoke (at 285°C), stays on the PCB for quite a while, almost no smell at all. And it already comes with a nozzle. No need to buy another one as I did. The nozzle was horrendously overpriced at close to 2$. I totally agree with the verdict of the guys at dangerousprototypes. I did a quick test job (TQFP-32 7x7 package) and it just worked nicely. One 'helping' of flux was enough. I didn't have to constantly re-add flux like in case of the FL-88 dispenser pen.
