Description of the invention (1) [Field of the invention] The present invention relates to measuring, for example, with LCD (liquid crystal) drive 1C and jet printer drive 1C Most of the manufacturers sell 1C output resistance measuring devices and measuring methods. [Background of the invention] The third circle shows an example of a drive 1C10 with a majority of pins. The number of pins varies depending on the type, but the number is from 160 to 300. Connect a low-voltage power supply to the power supply terminal V, etc., add GND to the ground terminal GND to drive 1C. At the multiple input terminals INi (i = 1 ~ η), a control signal is externally applied, and the control signal is used to instruct _sell name and its turn-out voltage. For example, the output voltage value is an 8-bit signal M 256 level command. The output of the majority wheel is 0UTi (i = l ~ is issued by the command _, and the specified fixed voltage value is supplied to the external load. The drive with the majority pin 1C (hereinafter referred to as "DUT ”) Most of the 10 exporters of OUTi use the control signal to supply the voltage and current after the command correctly to the load. And the wheel resistance must also be in accordance with the specifications. Here, in the past, it was the manufacturing process of DUT 10. Or after manufacturing or during material inspection *, measure the output voltage, drawn current or wheel resistance of each slap DUT10, and use M to check the quality of the DUT10. Circle 4 shows the previous inspection method. DC Measuring Device 15 It is a voltage stabilizer with a fixed electric roller source built in. It can spit out or inhale a constant current of any value, so the output electric roller I can be set, and the output voltage V of DUT10 can also be supported, and The wheel resistance R can be measured. The wheel resistance R is the difference between the voltage value V at the time of no load and the voltage value V at the time of load "the value of the load current value I divided by the pressure. The number is expressed on paper The scale is applicable to China National Standard (CNS) Α4 specification (210Χ297mm) (please Read the precautions on the back and fill in this page). Binding · Order 315417 A7 B7 Printed by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5. Invention Instructions (2), then RQ = (ν〇- VM> / IL. Load voltage The value VM is determined by using a pressure tester. The fourth (A) park is to measure the outgoing voltage of the majority of the output pins OUTi of the DUT 10, the current and the applied voltage to determine the type, M—a DC measuring device 15, one pin is replaced and replaced The method of conducting the test. Since the DC measuring device 15 is 1 kΩ, it is cheap, but the settling time is too slow. Section 4 (B) is to separate the DC measuring device 15Nch (channel>), and add Nch to the current. The pressure measurement mode is bound at the same time, and the MN pin is replaced every time. The Landing time is 1 / N compared to the 4th (A), but the Nch DC Landing device 15j (j = 1 ~ N) is required. Figure 4 (C) is a DC measuring device 15i with a full output pin OUTi (i = 1 ~ B) of DUT10. The test is performed. Therefore, the measurement time becomes very high, but since the DC measurement device 15 has all output pins OUT i divided, the price becomes Chang Penggui. The 4th (D) is the full output pin OUTi of DDT10 (i = 1 to 〇〇, respectively connected with M to prepare the programmable load PL20i. Moreover, each of the DUT10's nylon pin is connected to the high-speed scanner Each of the input terminals of 16. Carry out the PL20i on the powered roller system outside DUT10, and the voltage measurement is carried out by using a high-speed scanner 16, using a single measuring device 17. The voltage setting device 17 is used to prevent current flow. A high-speed scanner can be used. This method can be tested at a higher speed and is cheaper. The programmable load PL20 is shown in Fig. 5, which is composed of a 2-pole electric circuit source of ILL and ILH, and a voltage source of VT. Because there is a two-pole crocodile bridge connected to one end of the DUT10, the corner pressure system is connected to this paper. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) --------- ^ ------, order ------ i (please read the notes on the back of the first page before filling in this page) A7 printed by the consumer cooperation of the Central Standards Bureau of the Ministry of Economic Affairs ^ __ ^ _B7 · _ i 'Description of the invention (3) The voltage at the other end b of the VT is equal. Therefore, by changing the voltage K of the variable threshold voltage source VT, the voltage at the terminal a of the DUT 10L can be made variable. Set the DUT10's round-off level, if it is Η (high) level V0H, and L (low> level V0L *) set the voltage value of VT at its middle value, that is, VT = (V0H + V0L> / 2 , When the output level of 01 ^ 10 is at the H level, the load electric roller ILH is rolled out to the PL20 by the wheel-out pin. On the contrary, the load current ILL is supplied by the PL20 when the wheel-out level is at L Xiaoping Roll in to DUT10. The load currents ILH and ILL are the values in the specification chart, and roll through the fixed load to roll ILH or ILL. The conventional way of driving the output resistance of 1C is as described above, from 4A Up to 4D. The output resistance can be measured by any support method, and its value varies according to the type of DUT, but it ranges from 300Ω to several KΩ, generally around hundreds of Ω. However, each measurement method Although the measured value is reproducible, if the method is changed, most of its fixed value will be different. The measuring method * is to determine the fixed voltage by all the wheels OUT i_ out, and use the open switch to measure, or At the same time, it is determined. The difference of the measured values produced by the method of measuring the resistance value in turn is ± 100 Ω. This is because it is necessary to add the support method in the round of the resistance value, which is inconvenient and is an incorrect measured value. The reason is due to the type or design of DUT10, but each _sells the Xiaoyuan and _resistance It is not independent, it is known that there are two interconnections in the E section of the tilting section of the _ out of the department, and they interfere with each other. The purpose of the S here is not only due to the interference of the electromagnetic induction caused by the sensation or enchantment. Most of them are the interference caused by the consideration of the resistance circuit, etc. In addition, the above paper standard is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) ------- --------- 、 玎 ------ 0 (Please read the precautions on the back before filling in this page) 6 ___87 · · _ ____87 · · _ The Ministry of Economic Affairs Central Bureau of Samples and Consumers Cooperative Printed A7 5. Description of the invention (4) Measurement method, the method in Figure 4A has no interference between the pins, and it is known that it can be measured accurately. Therefore, the measurement method from Figure 4B to 4D must be added to the measured value Correction value. The present invention is to review the conventional measurement method and provide a wheel resistance measuring device that drives 1C. Obtain the same value as the measurement result in Figure 4A. The method of improving the fourth 4D pressure so that there is no interference between the wheel and the pin can be constructed with high accuracy, high speed and low cost. In addition, it provides a wheel drive resistance that drives 1C In order to obtain the same value as the conclusive result of circle 4A, the measurement method was improved by K, so that there is no interference between _ sales, which can constitute high box accuracy, off speed and relatively cheap. The present invention is a review of the conventional method The circuit method of Figure 4D, after repeated experiments, uses a high-speed scanner and uses a single pressure measuring device, which can be measured with higher accuracy and higher speed.

Invention description ( 6) Balanced, no interference. The conventional PL Min voltage source can only be at the H level and L level of the DUT In the middle of the setting of the Η voltage, the Μ can only be made by the full pin_inbound flow, or the output flow, so interference will occur. The second invention is composed of the PL group that defines the arrangement of the threshold voltage source in the first invention VT1 and VT2 are alternately arranged. How is the design of the DUT structured? Divided into several tilted sections? It is generally unknown. Here, VT1 and VT2 are alternately arranged every 1 tilt to form the DUT The internal current balance is the best configuration of K. The third invention is in the DUT catalog, which has more than two different types of measuring devices. When the resistance value is different, the current value flowing through the resistance changes in inverse proportion to the resistance value, which is well known. Therefore, in the DUT of the round out section of the wheel with different output resistance, the fixed electric rolling source of PL also It is necessary to have two fixed current sources on the system M. Secondly, add a description to the method of driving the output resistance of the 1C. First, set the fixed voltage VT1 with a higher voltage than the wheel of DUT. For program load, set lower fixed pressure VT2 for program load Next, the PL of VT1 is connected to the attention pin. Furthermore, VT2 and VT1 are arbitrarily connected to other pins. However, the total number of the VT1 group is the same as the total number of the VT2 group. In this state, it is difficult to support the attention pin. Similarly, the PL of VT2 is connected to the attention pin. Moreover, the VT1 and VT2 are connected to other pins at random. However, the total number of VT2 groups is consistent with the total number of VT1 groups. In this state, Landing's attention pin is out of the way. ° The paper size is applicable to China National Standard (CNS) A4 specification (210X297mm) I -------- install ------ order ------ line (please read the notes on the back first (Fill in this page again) 9 315417 Printed Α7 Β7 by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs.

Therefore, a fixed load current flows from PL20 of VT1 to DUT10, and a fixed load current flows into PL20 of VT2 In DUT10, if the fixed fixed soot charge and discharge fixed load current are the same amount, then in D In the UT10, the balance of rolling can be achieved without interference, and the resistance value can be pulled out with high accuracy, good reproducibility, and high-speed support. Figure 2 shows that there are 2 different types of resistance on the catalog. The measurement configuration of DUT10. The difference in the first figure is that the program can load the PL20 fixed rolling source system. It includes the fixed flow source PL20 with the group of ILL1 and ILH1; and ILL2 and ILH2. Even if the output resistance of the rolling source PL20 and DUT10 is different, it can be adapted to supply the structure of rolling with fixed load.
