Embodiment
For making the technical solution of the utility model clearly, below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.
Composition graphs 1, introduces a kind of CSP device test fixture described in the utility model.
As shown in Figure 1, a kind of CSP device test fixture that the present embodiment provides, comprising: LED component plummer 1 and the pressing 2 for contacting LED component be arranged on described LED component plummer 1.
Described LED component plummer 1 comprises that LED component lays district 11, described LED component lays district 11 for laying LED component 3, described LED component 3 bottom electrode place has thimble 12, described LED component plummer 1 inside has the inner chamber 13 receiving thimble, the top of described thimble 12 contacts with described LED component 3 bottom electrode, and the bottom of described thimble 12 also has the first spring 14.
The described number of the first spring 14 and the number of described thimble 12 match, in the present embodiment, described LED component bottom electrode place has two thimbles and two springs, mutually insulated between described two thimbles, two thimble tops contact with LED component bottom electrode respectively, be connected with the first spring bottom it, utilize the elastic property of spring can the lifting height of flexible LED component, ensure the effectively fixing of LED component.
Wherein, the top diameter of described thimble is less than the diameter bottom it, the top of thimble is hemispherical, in the present embodiment, described thimble is inverted T shape structure, is namely provided with boss 121 bottom described thimble, and the inner chamber 13 of described thimble is provided with gear platform 131, described gear platform 131 for propping up described boss 121 so that effectively prevent regulate LED component height time two thimbles depart from described LED component carrier-table surface.In the present embodiment, be communicated with power supply bottom described thimble by wire, after switching on power, electric current lights LED component by two thimbles, and utilizes lighting equipment to test light intensity and the wavelength of the LED component after lighting.
Described pressing 2 comprises the connecting portion 21 that is connected with LED component plummer and the contact jaw 22 with LED component surface contact.
