Thin PCB means printed circuit board thickness is more thin than Normal PCB, min thickness is 0.3mm or 0.4mm. Sometimes, maybe we need extra thin such as 0.25mm, 0.2mm or even 0.15mm PCB because of limiting space or margin, or design purpose requirement, this kind of thin PCB can be used as SIM card, sensor card and so on. Extra FR4 PCB is similar to flexible circuit, but more rigid, cost is lower. Thin PCB has better power decoupling, interplane capacitance, and better track-plane coupling.
