Dropbot assembly problem

#1

Hi guys

I recently got the feedback of Gold phoenix about assembly of PCB

They had two problems and I don’t know how to deal with that either.

So I need help

Thanks very much!

  1. On the BOM, J16 is populated with SSQ-103-23-F-D. Is this part to be soldered onto the bottom side of the PCB as shown in the photo attached?

  2. On the " 40-channel HV switching board" -BOM, J1 is populated with 15-24-4441 which needs to be soldered onto the top side of the PCB.

P1 is populated with S1111EC-06-ND which needs to be soldered onto the bottom side of the PCB.

If these two parts are soldered onto the PCB at the same time, the two plastic positioning pins of 15-24-4441 would cause the part S1111EC-06-ND to be unable to sit flush with the PCB just as shown in the photo attached.

Hi,

I can’t see any photo attached, but there’s a picture of an assembled switching board on the wiki:

Hopefully that can help to answer your questions?

Thanks Ryan
Your picture are very helpful.

And sorry for forgetting to attach the photo

I double check the photo, The first problem it should be correct,

The second one I am still not sure.

The attachment are the photos including one photo for problem 1 and three photos for problem 2

Thanks again

Best Regard
