By the plate phase welding, the center of the welded part is provided with a depression (9) which is positioned by kicking the ball and 2 feet, and the 0-shaped wheel of the concave section is the 20th.

However, in the process of the above-mentioned heated solder ball 20 being stenciled and fixed to the terminal soldering portion 13, the shape of the solder balls 20 and _13() is forwarded. Since the depression (10) breaks through the 20-shaped phase f-cake, the cavity 21 is formed in the body of the tin ball. The solder ball void 21 will reduce the electrical and thermal conductivity of the circuit. Hole 21 may reduce the resistance of the solder ball (four degrees), especially in the back environment test towel capacity reduction tin view. Second, it is necessary to provide an improved electrical connector terminal to overcome the above-mentioned electrical connector defects. σ [New content], the technology solved by this creation _ provides a kind of electrical connector terminals, especially the electrical connector terminals that can generate 钖 ball voids during the ball heating process. In order to solve the problem, it is referred to as 6 M318206 in the bottom surface of the bottom of the terminal of the electrical connector terminal. The central position is provided with a recess for receiving the positioning tin ball, and the concave contour does not completely correspond to the shape of the solder ball. The inner surface is composed of a side surface, and the inner side surface and the surface of the solder ball form a certain space, and the space provides a channel for the volatilization of the gas generated by the heat in the recess during the pre-planting, thereby smoothly escapes, effectively reducing the tin after the ball is implanted. A void is created in the ball. Compared with the prior art, the present invention has the following advantages: the concave inner surface provided on the bottom surface of the terminal of the artificial connector of the present invention is composed of a plurality of sides, whereby the concave contour and the shape of the solder ball are not completely Correspondingly, the gas generated by the flux is smoothly escaped from the space of the spherical surface and the concave surface, thereby effectively avoiding the shape of the concave contour of the contact ball corresponding to the gas not being able to escape the paste - part of the gas enters the partially tinned spheroid The formation of voids prevents the occurrence of tin cracking in subsequent environmental tests and improves the electrical conductivity and thermal conductivity of the circuit. [Embodiment] Referring to the third and fourth figures, the present electrical connector terminal 3 is provided with a holding portion 31 housed in the inner side of the electrical connector (not shown), and the two ends of the collar The contact portion 32 extending from the connection group (not shown) and the solder portion 33 connected to the circuit board (not shown) are respectively folded to form a sheet-like structure in which the bottom end is vertically folded. A recess 33 is provided at a bottom portion of the soldering portion at the bottom of the electrical connector terminal for receiving the positioning solder ball 4. In this embodiment, the recess 33 is used for the outer rim and the flux is used for the side of the contour. The four sides are used. The recess 33G gradually increases in cross section from the bottom to the outer (four). In this example, there are four isosceles trapezoidal sides between the two corridors of the 330^ shape class 2, and the whole is concave, wide t, and Mencius. The inner surface of each of the two adjacent sides of the recess 33 is heated by the adhesive in the recess 33G when the adhesive is produced;::, Γ I30 sub-welding portion 33 is the ball. > Luga", to - heart degree Lai ball 4 pieces of fine Wil connected to the end of the bottom of the structure of the 'best connection part 33 has a mosquito-age area can be relied on the ball fixed in the Xi Temple for the depression 330 The gas generated by the heat of the solder is out = the tin crack is generated to improve the position of the solder, thereby preventing the outer contour of the recess 330 from being a regular quadrangle in the above embodiment, and the corresponding side is also four, .3, 7 M318206, a pentagon or More sides and sides are also as long as they are not _ balls, and are not limited to the regular polygons such as - the arcs protruding toward the center of the depression, correspondingly inside. The sides of the shape may also be non-linear through holes 330 inside and outside The channel can be used, and the sides of the face and the spherical surface can form a smooth degree.
