Description
Technical field
What the present invention relates to is a kind of pick-up unit, particularly be a kind of ball that utilizes, make radiating module and heating element in testing process, can mutually adjust to reach the resistance detection device of heat of abundant applying.
Background technology
See also shown in Figure 1A, a kind of " general-purpose radiating module test fixture " for Taiwan letters patent book number M268578 in the prior art, it is that to include an external form be rectangular main body base 910, be to offer two locking holes, 911, two locking holes 911 mainly to fix (shown in Figure 1B) on the main body base 910 with a clamp base 930; Again, be that to be provided with an external form be rectangular Connection Block 912 on the main body base 910, also offer two locking holes 913 on the Connection Block 912, it is that main body base 910 with the below fixes, and the adjacent central place is that to convex with an external form be rectangular block seat 914 on the Connection Block 912; In addition, be close on the two-phase respective side of block seat 914 on the Connection Block 912, be pivoted with a hinge (hinge) 915 respectively, two hinge 915 is articulated with two sides of a fixing frame plate 916 again, fixing frame plate 916 is that center of rotation is done one and started or the action of pressing with two hinge 915, simultaneously, the block seat 914 on the Connection Block 912 can prevent that fixing frame plate 916 from starting toppling over after excessive.
Because the plate central authorities of fixing frame plate 916 offer at least one hollow-out parts 917, and hollow-out parts 917 1 sides are connected with a radiating module 920, radiating module 920 is that to have an outer shape be square heat radiation lamellar body 921, the end face of heat radiation lamellar body 921 is to be provided with a radiator fan 925, the two-phase respective side of heat radiation lamellar body 921 bottom surfaces respectively is provided with a link 922 outward, two links 922 are combined on the fixing frame plate 916 with a predetermined gap by a plurality of elastic partss 923 respectively, so, when fixing frame plate 916 is after center of rotation is done the action of a pressing with two hinge 915, the bottom surface of heat radiation lamellar body 921 can with a board under test 932 among Central Processing Unit (CPU) 933 do one and combine (shown in Figure 1B), and can utilize these a little elastic partss 923 to carry out the joint movement of an automatic guiding.
Please consult again shown in Figure 1B and Fig. 1 C, can know and learn, main body base 910 is locked on clamp base 930 by two locking holes 911, radiator fan 925 power supplys that will dispel the heat again on the lamellar body 921 connect, and board under test 932 put up by the complex root support column of being laid on the clamp base 930 931, and paste and put a heat radiation masking foil 924 (shown in Figure 1A) on the bottom surface of heat radiation lamellar body 921, so, can be that center of rotation is done a down action of pressing (shown in Figure 1B) with two hinge 915 with fixing frame plate 916, Central Processing Unit 933 among it just can be pressed together on and treat on the side plate 932, simultaneously, utilize these a little elastic partss 923 to carry out the joint movement (shown in Fig. 1 C) of an automatic guiding, at this moment, inlay card assembly 926 is that inlay card is fixed on the trip 929, and when trip 929 and inlay card assembly 926 are separated, can up start described fixing frame plate 916 make on radiating module 920 and the board under test 932 among Central Processing Unit 933 separate.
Yet, when using spring when improving the structure of this resistance detection device of heat, also because of spring uses the elastic fatigue that produces to cause thermal resistance to detect repeatedly error takes place easily.Therefore, how to go to improve above-mentioned prior art disappearance, real in pressing for the problem of solution at present.
Summary of the invention
Because above-mentioned problem, purpose of the present invention is for providing a kind of heat resistance detection device of heat radiating module, by an accommodation space is set in lower fixed frame, and install a ball, make when suspending mechanism presses down, can radiating module be reduced with the tolerance that contacts of heating element by ball, to reach the effect of improving the test data correctness.
Therefore, for reaching above-mentioned purpose,, comprise: a supporting part, a test section and a ball according to a kind of heat resistance detection device of heat radiating module of the present invention.Supporting part has a suspending mechanism, can put a determinand, in order to carry out a linear movement.Test section has an accommodation space.Ball is to put in accommodation space, and a gap is apart arranged between accommodation space and the ball, makes ball can carry out a displacement movement in accommodation space.
