At Jet Engineering, we machine custom FR4 spacers, end plates, and insulators that are engineered to match your busbar designs perfectly.
FR4 and epoxy fiberglass are used throughout the "architecture" of an electric vehicle's battery. Because they are stiff, lightweight, and don't conduct electricity, they act like the "skeleton" and "armor" for the battery cells.
We can cut any design or any share of FR4 sheet of any thickness.
