Weird circuit board with only resistors
Click For Summary
Discussion Overview
The discussion revolves around a circuit board that consists solely of resistors, with participants speculating on its purpose and the potential presence of other components. The context includes exploration of circuit design, assembly, and educational use in a physics setting.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- Some participants question the purpose of the board, noting the absence of components other than resistors.
- There are suggestions that the board may be incomplete or intended for educational purposes, possibly as a demonstration of printed circuits.
- One participant mentions the possibility of holes for other components like capacitors, transistors, and diodes, indicating that the board might be unfinished.
- Another participant emphasizes the lack of connectors and suggests that the board is unlikely to have fine-pitch surface mount components on the reverse side.
- A participant shares that the board was found in a high school physics collection, which raises questions about its intended use and origin.
- There is a suggestion to consult an external source for more information about the board.
Areas of Agreement / Disagreement
Participants express differing views on the board's purpose and completeness, with no consensus reached regarding its function or design. Some believe it may be a practice board, while others remain uncertain.
Contextual Notes
Participants note the lack of additional information about the board's origin and purpose, which limits the discussion's conclusions. There are also references to the need for links to sources for images, indicating a reliance on external validation.

and what is on the other side of the board ?, probably lots of other components ??

Thread moved. I agree with @davenn -- show us the other side of the PCBA.davenn said:
There are no apparent connectors into this PCBA, and this side is the through-hole top side, so it's unlikely there are fine-pitch SMT ISs on the other side... Where did you find this picture? Usually we require links to the source of images or the threads are deleted...
UPDATE -- Need links to your source...

OK ... well my only other thought then would be that it may be an incomplete board ( as in i's assembly hasn't been finished)greypilgrim said:
there are lots of other holes that may be for capacitors, transistors ad diodes
there are also a number of holes (particularly on the right side of first pic) where I/O/ power wires may get connected

I took the pictures myself. I found the board in a high school physics collection, in a drawer with other random boards, probably just to show the students examples of printed circuits. There was no further information and nobody knew who originally put it there.

OK ... so without any other info ... go with my last comments

Then it looks like a practice ICT/soldering PCBA. Thread closed for now so nobody else wastes time on it. Please PM me if you have ideas that merit re-opening the thread.
