Description

M341209 VIII. New description: [New technical field] This creation is a universal test device for working precision resistors, especially for the use of test pads with corresponding pre-defined and independent numbers. Using the test machine's measurement points to connect, the combination of the adapter box and the test panel made by the Dependent No. is 'the signal of the tested point can be connected to the four-wire type by the Lai section. (or the electronic circuit of the function _) the measurement of the precision resistor, # 俾 to achieve the purpose of reducing the cost of the production of special test fixtures. [Prior Art] Guangshendi, the universal tester for the 'press'-like circuit board test shown in Figure 4, the multiple electronic detection points A1 on the dial A are arranged in a dot matrix, and the overall structure is

The accommodating object is entangled in a multi-paste, and there is a gap between the baffle plate B and the guide plate B. The distance between the jig and the guide plate B is off, and the wire is inserted into the jig. The needle is guided by the guide plate B. Guided to a vertical or oblique guide to the point matrix electronic detection point of the universal test machine. The conventional electronic test point ai production method of the universal tester dial A is divided into the following two types; among them, the first type is produced - the dial-arranged dial A is connected to the probe A2 and the electronic detect The detection point α on the card c is measured, as shown in FIG. 3). Another method is to make the array on the electronic card C into a matrix of dots, and then combine the two electronic signature cards ',, and, to form a larger area of larger area. Point matrix extraction point (please refer to Figure 4). 4 5 M341209 Although the above-mentioned conventional universal tester can measure the general circuit board, the reason why it can't measure the loose resistance is as follows: Oral test 4 fine & requires a four-wire test method, that is, in one Point DJlf Wei (connect) two probes D1, the strip has two sides on it, so it is necessary to tie (connect) four probes (as shown in Figure 5) to the four-wire resistance measuring meter E. Nowadays, the electronic detection point on the universal test machine is switched by the transistor, and the electric meter or circuit for measuring the resistance is switched to the point to be measured through the switching action of the transistor switch F (eg Figure 6)). However, due to the physical characteristics of electricity and body, there are problems such as leakage current and impedance. Therefore, the measured resistance of the measured line of the meter is not very accurate. If it is expected to be able to measure the four-wire resistance from the improved 10,000 tester, it is actually quite ok and inconvenient, because the dot matrix detection points on the universal machine are already in production and Lock on the machine. If you want to measure the four-wire resistance from some test points, you need to use the dot matrix _ point pull wire on the machine of the universal test machine to the four-wire resistance measuring meter (or circuit). ). However, the location of the measured points of each measured item number is not the same. When testing different item numbers, it is necessary to repeat (4) repeated disassembly and assembly, resulting in a lot of _ degrees in actual modification, so It is almost impossible for the industry to adopt the scale method, that is, the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In order to solve the four-wire resistance measurement problem, special test materials must be made according to each group of different material numbers. After the general test action is completed, the object to be tested is moved to the fourth line resistance measurement test fixture. Carry out the trick. However, the special test and treatment 6 M341209 in the cost of the ancestral test structure, the method of pulling or smashing the axis of the phase # high, in fact, for the burden of the test industry, for the high county of the turn of the job or for the improvement of the real industry A very important topic.
