New PCB Color !

Written by cafealpha 2 comments
So I'm currently preparing next batch of Gamer's Cartridge, and am glad to introduce new PCB color


Gamer's Cartridge PCBs in various colors

I unfortunately didn't had blue Rev 3.3 (b) PCB when taking the picture above ... in fact, it's a long time I didn't soldered blue PCBs


The main interest in soldering PCBs with different colors is to make soldering activity funny, which is important for me since cartridges are assembled by hand : if making cartridges would become boring, I would prefer to stop everything rather than automatize assembly process !

My impressions after soldering a black PCB are ... a bit mixed : yeah, the PCB looks cool, but there's no contrast between tracks and isolated areas, so I definitely wouldn't use this color for new projects
One example of this lack of contrast can be found in cow logo, whose rendering is terrible in black color :
Cow logo on black PCB ... playing hide and seek

Among PCB colors I tried so far, I personally prefer ... standard green color, and then maybe red color. Also, I still didn't tested yellow color, so let's try it on next batch  I fear that contrast won't be better than on green PCB however

Being able to see green better could have something to do with the green colour space being the most visible to the human eye - I believe that's why night vision is typically tinted green!

Or I could be talking nonsense.

Maybe ... or maybe not, I don't know ^^; What's sure is that the "near zero contrast" on black PCBs is by design, in order to make them looking classy.
(PS : sorry for the delay !!)
