Fifty shades of Gray

Ever wondered what happens to an alumininium copper clad board when left at 270ÂșC for a few hours? nope?…

…damn, you still lack imagination!

The connectors should be white. XD
Surprisingly, the boards lit!, I wasn’t expecting them to. However, all the solder joints failed if touched:

Well, live and learn, some say.

Now, back to work, for a while.

Technician Strange for you, bastard.

Soundtrack:

Patient presents absolute lack of sensitivity on one of it’s moving members, can’t tell it’s position, open or closed. X-Ray reveals broken blood supply and nerve:

Closeup, it’s really a mess:

Boss prognosis: Irrepairable.

Me: Nope, it can be done.

Boss: No, it’s too close to the base.

Me: Watch me.

Inductive sensor is sedated:

I carefully cut the sheath of the cables:

patient-003

Exposing as much as possible (later I removed as many resin as I could up to the metal).

patient-004

Cable is completely destroyed, it is missing like half a millimetre of wires, all broken in pieces.

patient-005

Apply some solder paste and heat with a really fine tip, repeat as needed to extend the solder up the cable in both directions.

patient-006

There, it’s not pretty, but will hold.

patient-007

Cover in shrinkwrap:

patient-008

Next!

patient-009

Same, expose, apply paste, heat, repeat:

patient-010

Much better, ain’t it?

patient-011

I did the same for the third cable, but it is pointless to show it.

Aaaaand, of course, it worked.

BTW, this post is funnier if you actually saw the movie. ;)

This is what happens when everything is set up wrong:

Incorrect nozzle, bent pcb, excess puff-off, basically, the nightmare before christmas.

And if you think that’s bad, check this other one out:

Most of the circumstances escaped either my control (I’m forced to use that particular nozzle, can’t do much about the bent pcb) or my expertise (puff-off is a bit of magick trick, requires lots of experience)

Well, I’ll do better next time /laughs, then cries/

XD!
