Hi,
okay, since it seems a larger battery would help, I've now asked Fatih to check back with the case company what can be done here.
I guess with double the thickness (would be about 3mm thicker), we could get double the capacity. Maybe for 1,5mm, we could get 150% of the capacity?
Yes.
We might also be able to increase the width a bit by maybe moving the Stylus into a bit more into the edge and using a bit more of that empty space.
I know there's the UMTS antenna there, but we still might get a few mm
- maybe that helps.
I am not sure if you can get any arbitrary size of batteries. They usually come as cells which are bundled together. And the cells have the dimensions they have. So you can only get multiples of the basic cell size.
Or you find a cell supplier with slightly bigger cells. But I think there are not many different cell suppliers - just zillions of battery pack customizers.
With the PCBs with all important parts on being sent to the case company, I'll ask them if they can find a way to somehow increase the battery compartment as well.
As we all agree that a pluggable module as SoC would be great, we should also try to find out what thickness we would need for that soon.
Yes, I have some ideas that I need to draw and verify.
I'd say if it adds about 1 - 2mm in thickness, it would probably be worth it, as the lid will probably be thinner than with the Pandora.
We need to take care of battery connectors that can handle the bigger distance of the battery from the PCB.
What do you think?
And even if the module is not pluggable, maybe a reflow-one (similar to the Jorjin module) could be designed, with a very thin PCB.
Yes. This is one of the options. One may be a mix - a very thin PCB and some flat connectors to the left and right.
It still would limit the 8-layer PCB to a very small module size.
One issue might be that a really flat 8 layer PCB may be more expensive than making the whole board in 8 layers but 1mm. That is the next multidimensional topic to find an optimum between technology and cost and production :)
What do you guys think?
