# What sample thickness fits in QCage.24?

 The intended thickness is 525 µm (standard for 4-inch wafers). The suspended pedestal height will work for sample thickness ranging from 475 um to 575 µm. For thinner sample thickness, we provide a metal spacer to place under the chip with an 8 x 8 mm clearance area. For thicker sample thickness, we provide a metal spacer to place under the PCB. Both are 125 µm thick and can be stacked to support any sample thickness ranging 225 µm to 950 µm.
