Can we talk about how people keep replacing laptop dc jacks without reflowing the solder
Honestly, I see this all the time from techs who should know better. They pop open a laptop, see the jack is loose, and just slap a new one on with a soldering iron for two seconds. But here is the thing, the pads on the board are usually torn or cold from the old jack yanking on them. I had a Dell Latitude come in from a guy in Portland who did his own repair. He paid $12 for a jack and killed a $400 motherboard because he did not reflow the ground pads. It took me 20 minutes with a hot air station and some flux to fix it right. If you are not checking continuity on all five pins before you close it up, you are rolling dice. How many of you actually test the charge circuit under load after a jack swap, or do you just plug it in and hope?

Man, come on. Is reflowing really the magic fix for every jack swap? I have done a hundred of these with just an iron and good flux and they hold up fine. The real issue with that Dell was probably the guy cranked the cable in and out a thousand times, not that he skipped some special reflow step. Pads tear from force, not from a guy using an iron for two seconds. And testing under load? Plug it in, wiggle the cable, watch the charge light, done. Most boards are fine if you are not a gorilla with the plug. Sounds like you are making a simple job sound like brain surgery.
