Weird circuit board with only resistors
Click For Summary
SUMMARY
The discussion centers on a peculiar printed circuit board assembly (PCBA) predominantly featuring resistors, with no apparent connectors or additional components visible. Users speculate that the board may serve as a practice tool for ICT (In-Circuit Testing) or soldering exercises, given its incomplete assembly and the presence of numerous holes for potential components like capacitors and transistors. The board was discovered in a high school physics collection, intended for educational purposes, but lacks any identifiable source or manufacturer information.
PREREQUISITES- Understanding of printed circuit board assembly (PCBA) concepts
- Familiarity with electronic components such as resistors, capacitors, and transistors
- Knowledge of In-Circuit Testing (ICT) methodologies
- Basic soldering skills and techniques
- Research the role of resistors in electronic circuits
- Explore In-Circuit Testing (ICT) processes and tools
- Learn about the assembly and design of printed circuit boards (PCBs)
- Investigate common educational tools used in electronics training
Electronics students, hobbyists, educators in physics and electronics, and professionals interested in PCB design and assembly practices.

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.
