Pick it up.
06/15/2018 at 10:27 • 0 commentsHow do you handle wafer pieces to submerge them in HF acid and other cleaning baths?
You use tweezers, but HF will eat away any metal ones, and I would not trust much else other than HDPE plastic that can withstand it. However, I did not find accesible (cheap) ones, so I decided to make them, it's funnier and cheaper.
Too thick stock coupled to a short endmill marred the results a bit, but it proves the point, once I get thinner HDPE sheet, I'll make some more.
(and nope, my 3D printer is not working properly)

Bored? Watch a sputtering rig:

Pride and Depositionize.
05/14/2018 at 13:47 • 0 commentsToday I finally started to characterize the vacuum chamber, and also had some fun.

Stupid led circuit on glass, just before soldering:
The copper was too thin, and the solder paste just destroyed it when melted. In any case, the deposited copper passed the finger rubbing test, so, making circuits is just a factor of the time allowed in the chamber.

The cheapest HVAC valve I could find was pneumatic, so a miniature compressor and associated paraphernalia have had to be added to operate it.

Toolroom of Hell (part 1)

Since the semiconductor tubular oven has a very particular shape, special tools are needed to bring the Alumina bricks to shape.
Extended blog post about it: https://electronicmercenary.wordpress.com/2018/04/26/toolroom-of-hell/Video for the lazy ones. XD
