Embodiment Construction

[0024] Hereinafter, preferred embodiments of the present invention are given in conjunction with the drawings to illustrate the technical solutions of the present invention in detail.

[0025] Such as Figure 1 to Figure 2 As shown, the hot pressing device for soldering fine pitch connector pins provided by the present invention includes: a connecting board 1 and a hot pressing head 2, wherein two ends of the connecting board 1 are each provided with a hot pressing machine (Figure Not shown in) the fixed connecting hole 12; and in order to accurately contact the hot pressing area, the top 21 of the hot pressing head 2 is processed into a wedge shape, and the bottom 22 of the hot pressing head 2 is fixed to the connection The center of the plate 1.

[0026] Such as figure 2 As shown, the cross section of the wedge-shaped thermal head 2 is a trapezoid.

[0027] Further, as figure 1 As shown, both ends of the connecting plate 1 are provided with a groove 11 respectively, and two conn...

Abstract

The invention discloses a hot-press device for welding pins of a micro-spacing connector. The hot-press device comprises a connecting plate and a hot-press head, wherein two ends of the connecting plate are respectively provided with a connecting hole for being fixedly connected with a hot press machine, the top of the hot-press head is wedge-shaped, and the hot-press head is fixedly connected to the connecting plate through the bottom of the hot-press head. The invention further provides a hot-press method on the basis of the hot-press device. By adopting the hot-press device, not only can hot-press welding be performed on the pins of the micro-spacing connector, but also upwarp and obvious deformation are avoided when a mainboard is pressed. Besides, hot-press parameters of the hot press machine such as pressure, temperature and press time can be set according to practical conditions, consistency of hot-press operation indexes such as welding time, the temperature and the pressure is guaranteed, influence of unstable factors on welding quality during manual operation is avoided, and welding firmness of the pins of the micro-spacing connector is improved.

Description

Technical field [0001] The invention relates to a hot pressing device and a hot pressing method for pin welding of a fine pitch connector capable of preventing virtual welding. Background technique [0002] In the production of SMT (space mounting technology, surface mount technology), since the spacing between the pins of the micro-pitch connector on the motherboard is only 0.2mm, in the process of soldering, there will often be dummy pins of the micro-pitch connector. Welding problems, such as virtual welding of the PIN pin of the USB connector. This causes certain troubles to the functional test of the production line. At the same time, it will increase the defective rate of shipment quality, leading to lower customer satisfaction. The customer has to bear the risk of always worrying about the failure of the assembled connector, which will bring great adverse effects to both partners. [0003] The existing solution is to use a soldering iron to remedy the defect after the tes...
