I think there is a good spot for the headers to go. In the Enclosure version 0.1 (SLA) print I cut out the cutout and continued cutting to the wall at the top of that area.

You can see i this image where a connected header cable could sit. img_20150103_210735

And here is the header seated on the board in that same spot inside the enclosure. img_20150103_210807

And here is the header on the board without the enclosure back. img_20150103_210828

I think we would be okay if we moved the thermal isolation slots a bit.

Please advice the location of the connector on the PCB.

From the image I estimated the location of the connector, It seem a little bit difficult to move thermal isolation slots a bit, as the slot and the component at top side around 1mm distance. It is not suggest to place component too close to the slot.

charlespax commented 9 years ago

Can we move that component?

samchoy88 commented 9 years ago

Those components are thermocouple circuit, it has little bit space to move inside.

charlespax commented 9 years ago

Cool. Please nudge things around, so we can move the slot and get the header in there.

After I fixed the issue - Longer soler pads on 2x3 header footprint #122. The footprint pad size is larger than the component. the header cannot place on the position/orientation suggested by @charlespax.

Horizontal orientation made not enough space for the signal to the header
Separation between thermal-couple are fixed and not recommend to move. This made the slot can move very limited distance. (see below pictures)

It sounds like a feature we chose for the test rig is affecting the T400 design in a negative way. Any compromise that needs to be done should happen in the test rig. Rather than using the SIM connector we can figure our something else like individual spring contacts.

@samchoy88 can you place the 2x3 header in the desired location if we went back to the original footprint?

samchoy88 commented 9 years ago

Header position updated in Rev 0.10(unit = mm)

charlespax commented 9 years ago

Cool. Closing issue
