PC/104: Fitting components that are >15mm high
« on: May 13, 2021, 10:27:53 pm »
Has anyone done a project using a PC/104 stack where you had to use components greater than 15mm high? If so, what is the most professional way to go about it?  :-//

In my case, I want to include my power supply on the stack and I want to include my inductor which measures 15.37mm. Ideally I want there to be a gap.

Inductor: https://www.coilcraft.com/getmedia/a2805f49-c9b8-42c0-9939-b2d75eed7288/ser2900.pdf

Cheers everyone!

Stick an M/F connector onto the board to get double height.

Just add a number of bare pc-104 connectors to add height without adding boards.

I seem to recall buying some MF with really long tails and assembling boards maybe inches apart

Is this advisable in a situation where there is likely to be high vibration? I am putting it on a high altitude balloon.

Never heard of much vibration in a balloon. A B-29, yes.

If you "want to go professional about it", then stay within the spec of the allotted space.
Maybe you can put two inductors in series or in parallel.

Another possibility is to mill a big hole in the PCB, and mount the inductor from the underside.

I do find it strange though to use PC104 in a high altitude balloon.
PC104 is big and heavy. Does not matter much for an industrial environment, but a high altitude balloon is a bit different.
Also, Inductors that can handle 100A ???
If you've been using this design for 40+ years, then maybe it's time for a complete revision. Maybe build something that is the size and weight of, for example an average phone?
Including batteries!

A beast alright. I've used a LattePanda. Despite of its utterly infantile name, it works a treat in grown up applications.
