That's the template (jig)which is custom made and drilled to accept the pins. Gold test pins(probes/nodes if you will) inserted into it. Then one would wire wrap to each individual pin and create the entire wire harness connected back to the main diagnostic computer. You close the jig. One would lay the PCB which the test setup(jig) was designed for. Component side up squarely onto the gray material you see in the picture It is a material that allows a vacuum to be created and pull the PCB down onto the test nodes( pins) and seal it.
You can then via a monitor test individual components. Resistance. Capacitance. Inductance. Semiconductors. Also you can do potentiometer adjusts. It is a decent live circuit test. But. It does have it's limits. The final test is in the product the board was intended for. But it can catch a huge amount of preliminary problems before installed in the final product. For example. Phone. Stereo. Appliance. Etc.
That "board is not a pin board per say". You got alumimun and the fiberous board.
Like marked141 said. "Disassemble." Or email Boardsort.
I did board testing with that exact or very similar setup. You could test 100's of boards in a short time. Saving time and money.

Thank you so much for the time to explain that I was wondering myself exactly how it all worked . Thanks again

I feel like the pin population/density isn't there for wire wrap pin board, and may not qualify even if it was given wire wrap is a fairly specific category. Also there's no tracings in the board that I can see, makes sense given the whiskered one's description so there's no added value there. There is the silver color on the entire one side though so there may be a copper base layer and whatever the silver color is (I'm no good at guessing that).

So...worst case I'm thinking midgrade assuming the board itself is basically a blank with pins but even that might clear low peripheral. On the high end, if it's just a low population wire wrap then I'm guessing Boardsort might give you a price nearer the pin board category.


Basically, this seems like a bit of an outlier that would need Boardsort to weigh in on.
