Ok, some exciting news related to the clamp cards:
As I’ve said...
I’ve been doing a TON of research into pcb manufacturing: both of the vintage and modern variety.
I am very excited to say that...
Not only will the clamp card have the accurate trace widths and surface detail in between... but it will be made with a blue pcb substrate AND a custom soldermask color layering unique for the 7Chambers “MoM” run.... unlike any Hero card to date and visually the most accurate ever attempted.
Also: 100% manufactured in the USA!
(I’m American, so sue me... We don’t get to say that very often when it’s the honest truth)
I honestly can’t believe I found vendors both capable and willing to do this... it felt like it took forever.
The card will be 2” x 18mm x 1/16” thick.
it uses high quality 2 oz copper on both sides. One, with the surface detail- and the other will be standard like we’ve seen before. So you can pick your preferred flavor for display.
In the above attached photos you can see...
-the custom blue PCB substrate (notice the edge)
-the custom soldermask layer colors (I’ve selected the “greener” of the tests).
-the comparison of the samples next to the original reference... hence my selection of the greener sample.
As we know from this research thread the cards’ coloration varies from shot to shot, but I believe these details will capture all of that variation.... represented beautifully in this card.
