What is the metal part mounted partly under the pcb, with all the solder points?
Just courious, the monitor is not in my reach anymore.
Thanks.

 

Standoff Here is a data sheet for two kinds of standoffs that "rivet" into the PCB.
The " solder points " are probably just VIAs. When current flows through a standoff it is common to put VIAs around the mounting hole to lower the resistance.
I cannot see the other side of the board to know for certain.

I helped a colleague many months ago with this monitor. We are not pro in electronics (him way less than me), so sometimes we open faulty equipment to look for obvious problems, burned or corroded parts, and I dont remember what the problem was, not even brand or model. It was his field, not mine...
Just took the photo. I should have looked at what was underneath. The pcb has two black screws, I now notice, so not neccessary with some positioning-pin, and absolutely not that big.

Maybe som mounting/threading for something on the other side, who knows...

I thought it could be some sensor, shaking sensor maybe, but dont think so actually... the soldering was strange - solder on each side of the small holes, but not the holes...well...
Thanks anyway.

Edit: Could it be some coil, dual/quad coil???
The line beside is marked H4... (transformer?)

If you look at the opposite side, you see the same thing with a screw through it.
I'm with @ronsimpson on this one. Looks like a grounded mounting hole.

I can see H4, H3, H1 and there appears to be one more. H=hole in this case. It is very common to have Mounting Holes in the corners.

Youre absolutely right.
First now - I see all the solderings are connected on the same track/layer, and just now I catched the other one in the opposite corner.
You think its the end of the screw, the shiny surface in the middle?

I think you have half of the screws pointing down and half going up. That is unusual but OK.

Wonder what the screws function is.
The other two black screws also seem to be grounding.

 

What is the H2 component?
Can I measure if its OK or faulty?

Its in a pro Li-Ion battery ($500 range) taking no charging anymore (not totally dead, but no charging possible, except for feeding the cells directly/internally).

Thanks

 

Not sure why my latest posting got moved to this thread, it was supposed to be a different thread with the following title:
Identify SMD-component marked H2 and PCB marked FR1...?
(I will give it a new try, posting as separate thread)
