Embodiment Construction

[0022] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Specific embodiments of the wettability experiment sample clamping device of the present invention, such as Figure 2 to Figure 4 As shown, the sample clamping device for the wettability experiment includes a hanging rod 1 and a hanging rod 6 that are perpendicular to each other, wherein the hanging rod 1 is symmetrically arranged on both sides of the axis of the hanging rod. When in use, the hanging rod 1 is hooked on the On other carriers, the hanging rod and the hanging rod 6 hang down naturally, and the hanging rod can swing around the axis of the hanging rod. The axis of the suspension rod 6 and the axis of the suspension rod 1 constitute a swing surface.

[0024] Goniometer 2, angle control instrument and fixture 5 are arranged successively on suspension bar 6 from top to bottom, wherein, goniometer 2 comprises the angle disc 23 of transpar...

Abstract

The invention provides a test sample clamping device for a wettability experiment. The problem of an inaccurate measuring result caused by a relatively big error between a preset dipping angle and an actual dipping angle of a to-be-tested sample in the prior art is solved. The test sample clamping device for the wettability experiment comprises a hanging rod; a clamp for clamping the to-be-tested sample is arranged at the lower end of the hanging rod; a mark for cooperating with an angle disk to measure the dipping angle of the to-be-tested sample is arranged on the hanging rod; an angle control instrument for driving the hanging rod to swing to change the dipping angle of the to-be-tested angle is arranged on the hanging rod; the angle control instrument comprises a movable counter weight arranged on the hanging rod; and the moving direction of the counter weight is perpendicular to the swinging axis of the hanging rod. The clamping device is in a naturally droop state after clamping the test sample, the dipping angle is not changed and an inaccurate measuring result is not caused.

Description

technical field [0001] The invention relates to a sample clamping device for wettability experiment. Background technique [0002] With the enhancement of people's awareness of environmental protection and the development of electronic products towards miniaturization, multi-function and high power, the development of new lead-free solder with excellent comprehensive performance has become the development trend of the electronics industry. As an important aspect of judging the brazing process performance of solder alloys, wetting property has received extensive attention. In the prior art, wave soldering is mostly used for welding between multi-pin components and leads. On the one hand, there is an inclination angle of 3-7° between multi-pin components and the horizontal plane during wave soldering; On the one hand, during the wetting process, the multi-pin components and leads form an angle of 20-45° with the solder liquid surface. Therefore, in order to effectively simul...
