Problems solved by technology

In September 1998, the technical document "CFJ-FORMAT JOB FILE MANUAL" (CFJ program work file manual) of the CMT-600R test system published by Ruhlamat, Germany also mentioned the related test system, but it was limited to the functional test of the chip. Part, there is no description of electrical performance testing, and there is no method and technique for electrical performance testing

Embodiment Construction

[0016] Such as figure 1 Shown, test system of the present invention specifically comprises:

[0017] PC board: inserted into the PC, the PC controls the test system through it.

[0018] DC parameter measurement unit PMU: Provides accurate regulated voltage or regulated current power supply, and can test items such as high-precision voltage and current in various ranges.

[0019] Interface control board MIF: monitors whether the card is inserted and whether the signal light on the card holder panel is on.

[0020] The DPS board of the device under test is composed of six units: DPS1, DPS2, VIH, VIL, VOH, and VOL. They can be connected to every pin of the device under test through relays, that is, every contact of the chip. The DPS board is the power supply for the device under test, providing a DC power supply with general precision, and can also perform voltage or current tests with general precision. The setting voltage range is -10-+10V, and the precision is 20mV. The t...

Abstract

The system includes PC board, DC parameter measuring unit PMU, interface control board MIF, power DPS board for component to be tested, input high-levl voltage VIH, input low-level voltage VIL, output high-level comprison voltage VOH, output low-level comparison voltage VOL, sic pieces of passage board and module driving system. The present invention can carry on test for six or eight contact IC modules or IC cards simultaneously as it applies 14 position D / A to carry on sampling for various types of electricities with the minimum current rate of progress at uA grade.

Description

technical field [0001] The invention relates to a chip testing system, in particular to an IC card chip and module chip testing system, which belongs to the technical field of smart card manufacturing. Background technique [0002] The core of IC cards and modules is an IC chip, and the most important test is to test the electrical performance of the chip. The electrical performance test of IC card chips or module chips is the same as that of IC chips. Contact IC cards are mainly divided into two categories: storage type and intelligent type (CPU card). The storage type IC card is mainly composed of EEPROM or FLASH Memory, as well as some interface circuits, boost circuits, password verification circuits, and counters. There are relatively mature test methods for the test of EEPROM and FLASH Memory. The test of the CPU card is more complicated. If the test is completely performed by the test instrument, the generation of the test program is very difficult work, the require...
