Extra thin PCB refers to the finished thickness is smaller or equal to 0.25mm, some of our products even can reach to 0.15mm or smaller, so this makes you can install or apply it in some very thin or very small application.
This extra thin printed circuit means the thickness of printed circuit board is more thin than normal PCB. Normal thickness of PCB is from 1.0 mm to 2.0 mm, and the Min thickness is 0.3 mm or 0.4 mm (1L or 2L). For 4L PCB, thickness will be more about 0.6mm. This type of board always named as thin PCB, or thin board.
But sometimes, limited to space or margin, or needed by design purpose, people need much thinner thickness such as 0.25 mm, 0.20 mm, or even 0.15 mm, so that the PCB can be used in such as SIM card, sensor card, and so on. Because of extreme thickness, extra thin PCB, or very thin PCB name came out.
