Embodiment Construction

[0042] Describe the present invention below in conjunction with specific embodiment:

[0043] The invention discloses an auxiliary device for manually soldering packaging components with pins around the center and no pads in the center, such as image 3 shown. The device is composed of pressing components and clamping components, such as Figure 4 shown.

[0044] The compression assembly is composed of height adjustment handwheel, compression screw, bearing, bearing outer ring fixing plate and compression seat. The general structure diagram of the compression assembly is as follows: Figure 5 As shown, the height adjustment handwheel, compression screw, bearing outer ring fixed pressure plate and compression seat are as follows Figure 6 , 7 , 8, and 9. The lower end of the screw rod passes through the inner ring of the bearing (rotating part), and the outer ring of the bearing is fastened through the pressing plate and the pressing seat, and the pressing plate and the pr...

Abstract

The invention provides an auxiliary device for manually welding components. The auxiliary device is composed of a pressing assembly and a clamping assembly; the pressing component comprises a height adjusting hand wheel, a pressing screw, a bearing, a bearing outer ring fixing pressing plate and a pressing base; and the clamping assembly comprises a supporting plate, metal supports, clamping adjusting hand wheels, clamping screws and screw fixing blocks. The auxiliary device has the advantages that the pressing assembly can press the components, no displacement or rotation of the pressed components can be caused, and therefore relative isolation can be realized; and the clamping assembly support the components through L-shaped structures at the lower ends of the metal supports, the positions of the metal supports can be adjusted, expansion and retraction can be realized, and therefore the effect of clamping the components can be achieved.

Description

technical field [0001] The invention relates to the field of soldering technology, in particular to an auxiliary device for manual soldering packaged components with pins around the center and no pads in the center. Background technique [0002] With the development of circuit board integration and miniaturization, small package devices are widely used in circuit boards. Leadless package devices represented by LCCC packages, such as figure 1 As shown, it is widely used in military products because of its miniaturization, high density and high reliability. [0003] According to relevant research, during the temperature change process, appropriately increasing the soldering height of LCCC packaged devices can increase the solder in the gap between the device and the printed board, reduce the stress on the solder joints, and improve the reliability of the solder joints. The soldering height is as follows: figure 2 shown. For high-reliability products, CCGA package devices or...
