Description
Technical field
The present invention relates to a kind of wetability experiment sample clamping device.
Background technology
With development of the enhancing and electronic product of people's environmental consciousness to miniaturization, multifunction and high power, open
Sending out the novel lead-free solder of high comprehensive performance turns into the development trend of electronics industry.Wettability is as judgement brazing filler metal alloy pricker
One importance of Welding performance is of great interest.In the prior art, between the component and lead of more pins
Welding manner use wave-soldering more, on the one hand, have 3-7 ° between the component and horizontal plane of more pins during wave-soldering
Inclination angle；On the other hand, the component of more pins and lead and solder liquid level are in 20-45 ° of angle in wet processes.Therefore,
In order to effectively simulate the component of more pins and the Wet Out of lead during actual Wave crest Welding, it is necessary to by more pins
Component and lead（It is referred to as sample to be tested）With with solder liquid level it is at an angle immerse solder in.
Wetability test has two methods at present, first, soldered ball method, places a melting on the solder horn of heating platform
The solder droplet or bead of state, the horizontal decline of experiment wire or component that will scribble solder flux, make it into solder globules,
The small volume of liquid solder in soldered ball method, it is primarily adapted for use in single pin component less sample in equal volume.Another kind side
Method is weld groove method, as shown in figure 1, the brazing filler metal alloy of melting is placed in weld groove 5, the clamping of sample 4 to be moistened, which is adjusted, immerses angle
Degree（Angle i.e. between sample surface to be welded and solder liquid level）, sensor 3, signal conditioner 2 are provided with sample 4 to be moistened
And curvilinear recorder 1, controller 6 is connected with signal conditioner 2 and weld groove 5.Weld groove rises or wetting sample declines, and makes to treat
Soak sample to enter in weld groove, because the area of weld groove is larger, the wetability experiment of more pin components can be carried out.
Because sample to be moistened is to be entered with certain immersion angle in brazing filler metal alloy in experimentation, in the prior art
Certain immersion angle is preset to sample to be tested, is suspended on afterwards with clamp, fixture in other equipment, makes fixture downward
Mobile or weld groove moves up, and completes sample to be tested and is entered with certain immersion angle in brazing filler metal alloy.Ideally, fixture is being just
The position of centre of gravity of sample to be tested is clamped well, and after clamping sample to be tested, state is not swung before fixture stills remain in, now
Actual immersion angle it is consistent with default immersion angle, test result is more accurate.But during actual experiment, due to sample to be tested
Area it is larger, can not accurately clamp the position of centre of gravity of sample to be tested, sample to be tested can drive fixture to put under deadweight
It is dynamic, the immersion angle of sample to be tested is changed, actual immersion angle is changed compared with default immersion angle, leads
Cause actual immersion angle and error existing for default immersion angle larger, data are inaccurate.
