Title: You know it's going to be one of those days....
Post by: pickdropper on February 11, 2013, 10:02:20 PM
.....when you carefully solder a 100 pin micro controller only to realize once you've finished that pin one isn't correctly oriented.  Damn.

That.  Sucks.  I thought I was having a bad day when I forgot to solder Pin 1 on a 2399 which made my delay DOA, but you sir have that beat every which way.

At least on the bright side you noticed before you powered everything up ...

And BTW 100 pins???? Daaammmittt, what crazy improbabilty box are you going to drop on us next?

Knowing your skills, you could probably design a time machine to zip back and warn yourself in the same time it'd take to de-solder that...

Time for the hot air gun.  ;D

Already done.  Lost a couple of caps along the way, but no big deal.  The real problem is that I need to remove board mounted hardware to get the right angle to resolder the micro processor in.  It's entirely fixable but a stupid mistake.

It's not actually pedal related.  It's a work screw-up.

Back in my repair operator days, I used to routinely get 10s of pcb's just like that because someone loaded a pick and place tray 180 out.  BGAs, fie pitch, etc.   :-\. I feel your pain, but not too bad with the right tools!

Yeah, big oops if you load the P&P wrong.

Pulling off the PIC wasn't so bad.  Putting it back on is more difficult as I am not planning on reflowing or using the heat gun.  Getting it resoldered will happen it is just an unnecessary annoyance.
