Mac SE/30 Logic Board - AFTER Recap
This is the "after" photo of my socketted CPU SE/30 logic board, showing how the board looks now after my having cleaned the board with dehydrated ethanol and then replaced all the stock electrolytic capacitors on the top side of the board. I replaced all but C2 & C11 with tantalum capacitors. Tantalum replacements won't ever leak nor need to be replaced in the future like the stock silver tank capacitors. I also replaced C2 & C11 (the two axial caps) with axial electrolytic replacements simply because tantalums don't come in such large sizes. In total, I changed 11 silver SMD tank caps to tanalum and replaced the 2 axial caps. 47uF capacitors (Tantalum) are roughly 7.5mm long and 4.5mm wide.
WARNING! You do NOT orient SMD tantalum caps like you do a diode. On a diode, the strip on one side indicates the Negative. Not so on tantalum SMD caps!! It is the opposite. On tantalum caps, the strip side is the (+) Positive side!! You must remember this or you will destroy your new caps!!
Be sure to see how this board looked in its stock condition, prior to the recap.
NOTE: This board stopped working as shown in my YouTube video from 2011. It was later repaired by TechKnight at the 68kMLA. Be sure to expand the text description under that video on YouTube for details of the repair, as it may help you diagnose problems with recapped SE/30 motheroards.
