This post here. Check with @binkinator if you're still unsure
Hi, do you have any tip for soldering the mosfet? I'm finding very difficult to solder with my iron, because those pins are too small. Do I need a heat gun?
Thank you.
Thank you.
A good flux (I use chinese NC 559), bismuth core (melts at 138°C) and a heat gun, yes
I’d suggest either getting a flex from AliE or giving it to someone else with a scope, do not use a heat gun!
I need some help with this; is there a different mosfet with similar enough characteristics that can substitute for this secific model? Coz nobodys selling it locally in my country and Id have to pay customs with my kidneys if I imported it.
I sort of posted a couple datasheets in the original thread and asked if those would work but I got no response...

You are correct! I tried to be metric but it insists on being imperial units!Not trying to be a smartass but this is wrong.

1206 is indeed .125in by .06in and NOT 12mm by 06mm.

I saw in the other thread you need a j tip for the solder iron.
Its super fine
https://hakkousa.com/products/soldering/t30-j-angled-tip.html
you have posted much bigger and much weaker ones.
you need 2mm x 2mm SMD mosfet with 70A peak current
np2016 is an alternative

N type, 400 A, could be fine (even overkill)
but it is big, with required thick short wires it is easy to break caps
Update: I have modified and made it smaller and cheaper than original sx cpu cable.
WIP: Increase pad size to easier hand-solder.
Cost check with Oshpark for Flex option: $2.20 for 3.
Feedbacks/advices are welcomed.
BTW,@rehius just want to ask a quick question, Can I replace IRFHS8342 with:
- IRF7103
- AO3402
=> The point of this replacement is making it a little easier for novice/newbie who are not capable of soldering tiny components.
Thanks in advanced.

Mounts like on the SX CPU flex would be advisable, reduces he risk of the caps being torn off from negligence or a hard fall etc
This is awesome work!
If I may, a couple of suggestions:
i) move the P15 (gate) test point to a different position, so it stays away from the metallic shell surrounding the CPU (less probability of shorts)
ii) change the "k" to "c" as requested on the other thread by rehius.
PS: loved the homebrew slogan
