hey folks. i... i just had my first time. i liked it a lot. and i think i found my true love. bga packages are awesome and easy to solder and reball
-
-
until now, the only thing that prevented me from disassembling and reverse-engineering literally everything i meet was that i couldn't put anything with bgas back. now... now i am unstoppable!! INFINITE POWER HAHAHA

oh good it’s the gay gba
-
yeah!! i had this random cartridge and roommate who's into pokemon and wants to get into romhacking asked me if it's reflashable well none of the flash markings google but i found out what kinda flash it is anyway and yeah it's easily reflashable
-
i have two and i think i'm going to 3d print a cradle for it with pogo pins and make glasgow able to reflash it; if that works i can send you one. iirc commonly sold flash carts don't meet the strictest timings or something like that

Wow !!! You are my hero, I always hated doing those... super risk and not much confirmation technic, except power up nicely or smoke ...
-
well unless you misalign it or mount it in a wrong direction the worst thing that can happen is an open ball, which shouldn't lead to smoke on any well-designed circuit...
-
Well, you can push too hard on the top too , and get some short cuts ;-) the smaller the grid, the worse it gets.
-
right, I haven't worked with any fine pitch bgas yet. that said i think you aren't supposed to push on the top? nudging it a bit to the side to see if the solder melted properly is good, but pushing on the top seems too much to me
-
Yes, with hand, pushing is a bad idea, but with very large chips, the application tool will push, you are suppose to see the bubbles contract when melting and release stabilization when cooling, the hard part is to stabilize without pushing, while making contact.

oooh interesting!
