Recapped a swollen cap on a 2019 MacBook board and it booted, my shop lead says I got lucky and should've replaced the whole board
Honestly I keep hearing other techs say you should never touch surface mount caps, just swap the logic board and charge the customer. Had a MacBook come in from a client in Denver, wouldn't power on at all, and I found one bulging cap near the power rail. I swapped it with a $3 part off Digi-Key and the thing booted right up, that was 4 months ago and the client still uses it daily. My lead told me I was rolling the dice and that a proper shop replaces the whole board, but I think that mindset just makes customers pay $600 when $3 and 20 minutes does the job. Has anyone else gotten pushback for doing component level work instead of board swaps, or am I really playing with fire here?

The thing nobody brings up is what happens to all those swapped boards. Your lead's shop pulls a board with one bad cap, charges the customer for a new one, and then what? That board goes in a pile, gets sold to a refurb guy for cheap, and he fixes it and sells it right back into the market. So somebody down the line does exactly what you did. The only difference is the customer paid $600 instead of $50. The board swap model only works because somebody else does the component work eventually. You just cut out the middleman and saved the client money. The real risk isnt the repair itself, its whether you tested the rail and found out why that cap blew in the first place. A swollen cap is usually a symptom, not the disease. If you checked the voltages and the short is gone, you did the job right. If you just swapped it and hoped, then yeah, it might come back. But that has nothing to do with component work being wrong, thats just about doing it all the way through.
