Switch OLED teardown V1/V2

It's probably 0201. Best idea might be to get a resistor "sample book" from aliexpress, then you have virtually all common resistor values at once.

Thank you. I'll try that.

Indeed it is a 0201 packaging.

Maybe it's too much for you, but yeah, you can find it on Aliexpress

I ordered a sample book from Amazon It's expensive but should arrive here tomorrow. Currently, orders from AliExpress are expected to arrive next year the latest.

BTW the caps in the CPU area beeps in continuity mode. Is this normal.

yes it is normal, and it should beep with ground as well

Yes!
That's "normal" for capacitors near the CPU, specially on top of it

To those who ordered DAT0 adapters from me yesterday, those have been shipped. Good luck on your installs

It's genuinely shocking how popular my adapter became. Hope it helps everyone

Wasn't aware a member on here made this. Must say it is very well designed. The 'v'-groove latches on just perfectly. Was this the very first iteration of your design? Very impressive if so!

 

[doom95]

double post, apologies

Nice to, finally, meeting you!
Kudos for your idea and proactiveness!
Thx for helping the community, mate!
Cheers!

Good work on the adapter, it seems like the scene is using it as the defacto way to get to dat0.

I was wondering however, if you believe it can be optimised, to make it thinner, so it fits under the shield, so people don't have to rip it apart.

Another good addition would be "anchor" points, to fix it in place, instead of using solder mask.

I doodled something up in paint - let me know what you think:

This way you would first slide it under the shield, so it drops on the PCB and then you slide it under the eMMC with 1-2 tweezers.

The DAT0 point would peek out on the side.

Once you meassured the resistence against GND to check if it has a connection, you solder the adapter to the 2 caps / resistors on the side to keep it in place forever.

 

[doom95]

I had a similar thought. Only concern would be how accurately the placement of those caps reproduces.

Indeed we might have a misaligned anchor point, so we can always make the solder point on your "board" a bit bigger to accommodate for the misplacements of such anchor points.

It’s intentionally generic. This is so it’s not specifically designed for the switch. Making it thinner is up to the fab you make it with. PCBWay’s thinnest option is 0.08mm which is limited to one layer. The thinnest option with 2 layers is 0.1mm which is what the current design is to help people who are a bit heat ignorant and just blast 400c.

In terms of size, you’d want to have sides that wrap around the bga tightly so there’s no room for error. With your sketch you have the room to be misaligned. Obviously your anchors help with this, but this goes back to my first point about being intentionally generic.

 

[doom95]

Was it your intent that users reflow the eMMC chip after shoving the adapter underneath?

The got me thinking as well!
I'm curious

With thinner I meant making it smaller so it fits between the shield and eMMC, so peoppe don't have to rape the shield while installing it

But if you say it's a generic adapter, we have to design a Switch OLED specific one

 

[doom95]

'Rape' seems a little overstated, a small incision at the edge allows the overhanging part to be bent upwards and you can simply bend it back into place before you put the cover back on.
