I'm trying to integrate the joule module in my own design, but having a hard time to find a source for the standoffs.
Any idea, where to get them in the US?
Any idea for a suitable replacement?
I've an update for this.
I was checking the Bill of Materials of the Intel® Joule™ Expansion Board Schematic ( http://www.intel.com/content/dam/support/us/en/documents/joule-products/intel-joule-expansion-board-...). According to this document the standoffs (YQSMTSO-51732-ET) are supplied by PENN ENGINEERING & MFG CORP.
Based on their website ( http://www.pemnet.com/) the supplier is located in Philadelphia. You may need to contact them directly and ask for more information regarding that part.
As for suitable replacements we are not aware of any.
I hope this information helps.
I contacted them already and they have a minimum order of 7000 pieces, and even then, the standoffs are not a stock item.
(special order and 6 weeks wait)
So I can't say I'm happy with the choice of 1.6mm screws on the joule module. M2 or 2mm would be very common,
and could be bought easily from many sources.
All the best & thanks
I understand your point of view. The 1.6mm screws were chosen as they best fitted the designing needs for Joule. I can see how using non-standard screws can be frustrating and I apologize for this situation.
Nevertheless, I will pass your feedback to the appropriate team and hopefully they can provide us with a suitable replacement for this part. However, there's no ETA for when this might happen.
We have an update for your case.
When designing a custom board we recommend the use of a board mounted hardware that is soldered to the ground plane. When this is not possible, all metal hardware (screw and nut) that maintains the electrical ground path can be used to secure the module to the expansion board. See the attached drawing and the Design Guide for Intel® Joule™ Expansion Board (http://www.intel.com/content/www/us/en/support/boards-and-kits/intel-joule-kits/000023390.html http://www.intel.com/content/www/us/en/support/boards-and-kits/intel-joule-kits/000023390.html) for more information.
I hope this information helps.
and what you describe again, is exactly the problem. What is in the drawing the "Thru Hole Spacer".
I really tried hard, but I can't get any alternative part for it. It has to be metal, so it has the contact,
1.6mm drill or thread, 1.5mm tall, and it has to be solderable as an SMT component.
The only company which makes them, has a minimum order of 10000 pieces, and needs 6 weeks to make them.
Try simply to imagine the price tag on them then.
All the best
I understand your point, however we are not aware of any replacement for this part that you could use instead. Based on the latest Peter's post, the other option I can think of would be to not use the thru hole spacer and use only the screw and nut to secure the module to the expansion board. The important detail here is that all metal hardware (screw and nut) must maintain the electrical ground path. If you can do this with the screw and nut, then you could use a thru hole spacer that doesn't have to be soldered, or probably a thru hole spacer that doesn't require to be metal. Although, this is just an idea from the information provided by Peter.
I just wanted to recommend you to check the following thread: https://communities.intel.com/thread/110825 https://communities.intel.com/thread/110825. Another user shared some mounting hardware parts that he used successfully with Joule. He provided the specs and where to get them. Apparently they are available in small quantities.
Hope you find it useful.
it seems, that it is my only chance at the moment.
However, I'm still trying to get the right spacers (solder able, smt). I have four of those modules on one
board, and assembling them by hand with lose screws, spacers & nuts is a pain in the neck ;-)
I would like to add the following information to provide the McMaster part numbers for the board mounted hardware. Here is the information to add:
M1.6 x 8mm length, Phillips Round Head
Spacer: Length 1/16", Outer Dia: 1/8" and Inner Dia: 0.064"
Nut M1.6 x 0.35 mm Thread
I hope this helps you.
