PROCESS -> SORTING

Test Sorting Machine


A single charge when loaded for sputter coating consists of large quantity of Ceramic Substrates, results in a normal ohmic distribution around a nominal value which need to be segregated into narrower ranges to enable accurate trimming in the cutting process which determines the final value of the resistor.

The sorting machine measures the value of each capped substrate classifies and segregates the resistor physically in to bins which are set in stages of 5% increment from the set value. This ensures a narrow range of resistor cores whose spread is not over 5% resulting in a uniform even cutting length to establish accuracy of value, higher reliability of the product. The in-process Q.C inspector verifies the quality of sorting to ensure lack of overlapping between bins.
