Removing ports from raspberry pi 3

Post by jbodhorn » Sun Jun 11, 2017 2:38 pm

I've heard that due to all the layers in a raspberry pi's board people have trouble removing ports without causing shorts or other problems.

Is there any good way of removing ports without causing issues? How much magnification would be needed to properly check over the board after removing ports from it?

It's not hard to do properly if you have the right equipment...but of course equipment costs money:

Hot air is definitely the best way to remove all the ports, just set the air to ~270C and be patient. Eventually the solder will soften enough that you can start to wiggle the components with some pliers and they will come out easily.

I got to be honest, I removed the ports with pliers. I didn't rip it off, I gently removed the metal parts and then reduced the plastic parts, bit by bit. In the end the ports are unusable of course (literally in a hundred pieces), but it gets the works done. It took me 5 hours+ of slow and gentle manipulation to get everything off. ONLY AFTER THAT, did I start removing the last metal pieces stuck to the board by adding regular solder (not lead free), which decreases the melting temperature of the pi (ABRUGSCH I SUMMON YOU, PLEASE CONFIRM :mrgreen: ). And everything works. Last tip, the most important about my little success here is that I let the pi cooldown ALL THE TIME.

If you are interested I can give you more details.

Note: reading any pi-related forum, you will find people telling their story about how they ripped/destroyed/burnt/etc their pi when they gave it their chances on stripping a pi3. Honestly, they had no clue what they were dealing with. They just went too fast and now they are venting on the internet. Trying to get advice from the internet on stripping a pi3 is like making yourself an opinion of public healthcare by walking into a hospital.

Unfortunately tagging members doesn't work anymore but I saw it anyway ;)
Anyway swapping lead free for leaded doesn't lower the melting point by much however chip quick (I think is spelled) does exactly that by significantly reducing the melting point. It's meant for desoldering smd chips but no reason it wouldn't work for throughole ports too.

I'm not aware of the 3 being multi layer but it could be. I've only done this with an A+
