Here's a bad mistake. NEVER work on a computer while sweating profusly 8-( I think it was July 4 years ago, got the case open on its side, had to be 95 degrees out that night. One drip of sweat started to fall down my nose, DRIP, tried to catch it with my hand... Dang, missed it. Right on to the leads on my MB's intergrated 7890. Whatched helplessly as I watched the salty fluid wick under the chip. Bye bye SCSI. Got some distilled water.Driped with an eyedroper from the other side, with a wad o paper towels on the sweaty side to try to geet the salt out from under the chip. Followed up with Denatured alcohol. Then acetone to get the last of the H20. Oh how i hoped i got all of the salts and moisture out from under that chip. Waited servral days. Heated area of the chip with hair drier every day. Finally powered the beast back up. Nope, right the first time... Bye Bye SCSI I'm just glad I never did this at work repairing old 1970's hand laid circuit boards. some of the ones in my old machines cost $6000+ apiece used in 1995. Beautiful hand laid Gold wire boards, Also high voltage 680 Vac stuff.(its complicated.. shop had triple phase 380, machine wanted 500 VAC internaly, steped up to 680 routed through one or two boards then back down to 500 to the machine tool, I think, but i've slept since then) (industrial Wire EDM equiptment one had serial # 0002, Yep sill prototype. Always stumped the Techs from the manufactuer)
