How to Cut Silicon Wafers

I've only seen monocrystalline silicon cutting tools from decades ago that cut an internal circle. Simply put, they cut a round hole in the middle of a large steel sheet and apply emery and silicon rods to the inside edge. hole in the inner hole.

The most common marble cutting machines, wood saws and power tools are all cylindrical cuts.

6 inch silicon wafer weighs 0.0063 kg, 6.5 inch silicon wafer weighs 0.0065 kg, 8 inch silicon wafer weighs 0.01 kg.

But that doesn't mean that all silicon rods can become silicon wafers, because some of it was lost in the cutting process. The general loss is 40 to 50%.

The number of parts produced is also linked to the groove pitch of the main roller. Generally speaking, if you conservatively estimate it at 40%, for a 6.5 inch rod, 30kg x 40%= 12kg 12kg/0.0065. =1846 pieces
