Description of the invention (f) Through-hole 14 for wire insertion and welding, and through-hole for connecting the ground wire of the coaxial cable unit 20 16. The function board 30 has a through hole 34 through which the signal cable of the coaxial cable unit 20 can be inserted and welded, and a through hole 36 through which the ground cable of the coaxial cable unit 20 can be connected. The through hole 16 in the socket board 10 is connected to the ground line in the socket board 10, and the through hole 36 in the function board 30 is connected to the ground line in the function board 30. When testing the function of the semiconductor device 90, a high-speed signal is transmitted from the test device main body 80 to the function board 30. The test signal transmitted from the test device body 80 to the function board 30 is then transmitted to the socket circuit Π on the socket board via the coaxial cable unit 20 and the socket board 10.

Description of the invention (&) The ground layer 66 is welded with the cable terminal 40. In addition, the ground wire 64 is a folded cable terminal 40 It is welded to the outside of it. In addition, there is an insulation layer between the ground layer 66 and the signal 62. At the end portion 68, this insulation layer protrudes toward the top of the coaxial cable unit 20. In Figures 2B-2C The cable terminals 40 are respectively mounted on the two end portions 68 of the coaxial cable 60, but the cable terminals 40 may be mounted on only one end portion 68, which is an additional preferred embodiment. Figures 3A-3B The three-side view of the detailed structure of the cable terminal 40 shown in Figures 2A-2C is shown. The cable terminal 40 includes a casing 42 and an accessory 46, wherein the casing 42 surrounds the ground layer 66 of the coaxial cable 60, and the accessory 46 is along the coaxial cable. 60's axial extension, and accessories 46 and coaxial cable 60 The signal wires 62 are electrically connected to the housing 42 at an appropriate distance.

Description of the invention (1) In the cable terminal 40 There may be a shoulder 44 connected to the housing 42 and extending in the radial direction of the cable terminal 40. At this time, the accessory 46 is connected to the shoulder 44 and extends along the axial direction of the shoulder 44 to maintain a proper distance between the accessory 46 and the signal line 62, so that improper contact between the signal line 62 and the housing 42 can be avoided. Furthermore, a notch portion 48 is formed on the casing 42, which is located opposite to the fitting 46, so that the ground wire 64 can be bent outward from the inside of the casing 42 through the notch portion 48 to prevent the ground wire 64 from being bent. A protrusion is generated in part. Therefore, the cable terminal 40 can be brought into close contact with the socket board 10 and the function board 30, the connection strength of the cable terminal 40 and the socket board 10 and the function board 30 can be increased, and the connection impedance can be further reduced. In order to prevent the cable terminal 40 from being short-circuited with other cables and change the connection strength, it is preferable that the terminal portion 68 of the cable terminal 40 and the coaxial cable 60 be covered by an end tube cover (not shown). At this time, the small protruding portion 50 on the outer end of the housing 42 opposite to the fitting 46 prevents the end tube cover covering the cable terminal 40 and the end portion 68 of the coaxial cable 60 from moving. Therefore, the protruding portion 50 can prevent the cable terminal 40 from being exposed. As described above, since the signal line 62 penetrates the through hole 14 in the socket board 10 and the through hole 34 in the function board 30, the exposed portion of the signal line 62 is very small, thereby preventing the signal line 62 from being interfered by external noise. . In addition, since the grounding layer 66 of the coaxial cable 60 is connected to the grounding layer of the function board 30 and the socket board 10 in the place immediately adjacent to the signal line 62, the number of connections between the coaxial cable 60, the socket board 10, and the function board 30 can be reduced. Signal line impedance, and reduce signal reflection at the connection part. -------------- Loading --- (Please read the precautions on the back before filling this page) Order. 4 This paper size applies to China National Standard (CNS) A4 (210 X 297 (Mm) 454369 5927pif2.doc / 002 A7 B7 Printed by the Economic Consumer Intellectual Property Bureau Employee Consumer Cooperatives V. Description of the invention (γ) Furthermore, 'Because the electrical_terminal 40 can be soldered between the socket board 10 and the coaxial electrical connector 60' And between the function board 30 and the coaxial cable 60, the connection strength between the socket board 10, the function board 30, and the coaxial cable 60 can be strengthened. In addition, 'because the signal line 62 and the ground layer 66 are connected to each board through the through holes of each group', the connection strength is stronger than that of the direct welding to the board. At the same time, due to the small welding area, the stray capacitance can be reduced. When the maximum width of the accessory 46 is approximately equal to the diameter of the signal line 62, it is preferable that the size of the through holes 14 and 34 for the signal line 62 to pass through is equal to that of the accessory 46 on the socket board 10 and the function board 30. The size of the through holes 16 and 36 penetrated. However, when the size of the through-holes 14 and 34 for the signal line 62 is approximately equal to the size of the through-holes 16 and 36 for the accessory 46, the signal line 62 and the accessory 46 may each penetrate the wrong through-hole. To avoid this problem, it is preferable to make the diameter of the signal line 62 different from the width of the fitting 46, and the inner diameter of the through holes 14 and 34 different from the inner diameter of the through holes 16 and 36 of the fitting 46. Another thing to notice is that since the signal wires 62 and accessories 46 inserted into the socket board 10 and the function board 30 will protrude from the back of the socket board 10 and the function board 30, the signal wires 62 and the accessory 46 are free. If there is improper contact, the back protrusion length is better. In this way, at the time of manufacture, in the horizontal direction of the coaxial cable 60, the position of the top end portion of the accessory 46 is preferably the same as the position of the top portion of the signal line. As described above, the present invention can provide a fixed plate structure including a cable unit, a coaxial cable unit, and a cable terminal, and the connection strength between the coaxial cable and the circuit board is strong without the need for an assembly head or a screw device.
