In the eighth, the private seat 226 and the cover 222 can be integrated into the upper surface of the body 222 to limit the top oblique injection directly to the outside of the I, the cover 222 is accessible to the elastic member 224, and the body is firm; When the internal is subjected to the outer domain two probes to these __2 ,, these measurements are stretched by the size of 12 1286809 !7472twf.doc/r, thus ensuring that these tests 22 = 220 will be the chip package, these contacts c, an electrical path between the contacts 212 of the test circuit board 210. Therefore, =cp' will be electrically tested by the test probes 22 of the test module 2: the wafers in the body (9) (not shown). In the process of the electric seal test, the thimble 225 compresses the elastic member, so that the elastic 7L member 224 is completely immersed in the conductive colloid 223, and the needle 225 is partially immersed in the conductive portion of the body 22%. In the colloid 223. This: ten is in contact with the probe portion 225b of the thimble 225 to limit the displacement of the top and the lower portion of the tenth. Since the conductive paste 223 has the conductivity of the crucible 1 the test current is emitted by the 5th type circuit board 21 The vast majority of the = anti-path path to the ^ 钱 cp, that is, the borrowing: each order through the (four) 221 bottom, conductive colloid 223:,, the mouth is transferred to the chip package CP, and then by the chip package The version CP is returned to the test circuit board 21 〇. Compared with the prior art, the test probe 220 of the present invention and the test module (10) to which the test probe 22G is applied have a problem of poor contact due to damage. Therefore, the f-surface impedance of the thimbles 225, ¥, ¥ 223 is increased. Finally, it must be said In another embodiment of the present invention, the conductive colloidal crucible 3 may be replaced by a conductive powder or a conductive fluid to replace the rod in a pressurized state. The body 225a can be partially buried in the conductive powder, and the conductive powder is used to reduce the impedance and wear of the tube 122 (see FIG. 2) during signal transmission. The best conductivity of the material, so when the nano-silver particles or n, 'and silver powder to conduct the test current, the impedance value is very small, so the degree can be several times higher than the traditional probe, and then The test can be improved to solve the problem of poor conduction, etc. Further, although the present invention is embodied by the single-action=needle structure, the double-action probe-junction probe structure can be applied. The elastic member 224 can also be disposed or sleeved outside the barrel 221, and does not limit the county voyage. The other members can also replace the spring, and there is no such thing as a technique. There is no friction loss between the test phantoms of the two test probes of the needle test. The conductive conductive needle and the problem of poor detection of the X-ray test using the probe are increased due to the wear of the === degree, so that the impedance value between the π彡^ of the present invention is not tested. The group can maintain a better test yield. The clothing ~, how to use the test probe (b) because the test probe disk of the present invention is the ancestor of the cover body to seal the barrel and the measurement of the object needle During the electrical test, the dew y 0 ◊ gap in the barrel is overflowed, so it overflows during the feeding. (6) The electrocolloid does not shrink the elastic element due to the thimble. (2) Because the test of the invention is based on the test block How to limit the thimble, how to use the test probe's measurement, and the vertical shift 'Therefore the maximum displacement of the thimble compression elastic element 1286809 17472twf.doc/r is fixed.
