Green Solder Mask Rigid Flexible PCB 4 Layer with Immersion Gold
Multi-Layer flexible circuit is a combination of single and/or
double-sided flex circuits laminated with thermoset adhesive onto a
single and/or double-sided FR-4 clad material. Three or more
flexible conductive layers with flexible insulating layers between
each one, which are interconnected by way of plated through holes
(PTH). Layers range from 1 to 8 layers in the flex area and up to
10 layers in the rigid area.
