The invention provides a single-
chip microcomputer open-circuit and electric leakage tester and belongs to the field of
integrated circuit package testing technologies. The single-
chip microcomputer open-circuit and electric leakage tester comprises a power source unit, a main
control unit, a DA conversion unit, a
mode switching unit, a test unit and an AD conversion unit; the input end of the main
control unit is connected with the power source unit; the output end of the main
control unit is connected with the DA conversion unit; the input end of the
mode switching unit is connected with theoutput end of the main control unit; the output end of the
mode switching unit is connected with the input end of the DA conversion unit; the output end of the DA conversion unit is connected with the input end of the test unit; the output end of the test unit is connected with the input end of the AD conversion unit; and the output end of the AD conversion unit is connected with the input end ofthe main control unit. With the single-
chip microcomputer open-circuit electric leakage tester has an open short-circuit test and electric
leakage test function. With the single-chip microcomputer open-circuit and electric leakage tester adopted, an open short-circuit test and an electric
leakage test can be completed quickly and efficiently, and thus, the
rapid detection of possible electrical and physical defects in a
package product can be achieved.
