Hit 2000 motherboard repairs last Tuesday and it finally clicked for me
I've been doing board level repair out of my garage for about 4 years now. Last week I crossed 2000 repairs total and it surprised me how much I've learned. When I first started I thought replacing caps was the main skill. But somewhere around repair 500 I realized proper cleaning and inspection actually matters more than soldering. Hot air rework was a game changer once I practiced on dead boards for a month. Has anyone else hit a milestone that made them rethink their whole approach to troubleshooting?

and that cleaning thing is SO underrated right? I had the exact same realization around repair 1200 where I finally figured out that flux residue was causing more problems than the actual component failures. I used to rush through the cleaning part honestly, just a quick wipe and move on. But once I started spending real time with isopropyl alcohol and a stiff brush, my success rate went way up. Hot air was another one for me too, I practiced on a stack of dead laptop boards I got for free and it made a world of difference. It's funny how the stuff you thought was secondary at first ends up being the real key to getting things right the first time.

Yeah the cleaning thing is huge and I feel like nobody talks about it enough. I used to be so sloppy with it, just a quick alcohol wipe and call it done. But once I started really scrubbing boards down with a stiff brush and fresh isopropyl, my rework failures dropped like crazy. It's crazy how much hidden gunk causes intermittent shorts that drive you nuts for hours. Hot air was another big one for me too, I spent a whole weekend just desoldering and resoldering random components on junk boards until I got a feel for the airflow. That practice made me way more confident when I had to swap out a bad chip on a real job.
