FR4 is the standard glass-epoxy substrate for most PCBs — durable and solderable. Aluminum is used for LED and thermal applications; it cannot use Chemical Tin finish.

Surface Finish
?
Chemical Tin coats exposed copper via immersion tinning — solderable and durable. Raw Copper leaves copper bare — lower cost but oxidizes. Aluminum boards use Raw Aluminum (auto-selected).

Soldermask Color
?
The color of the UV-cured solder mask resin applied over the board. Only applies to Chemical Tin boards. Green is standard and lowest cost.
