Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
Consult shown in Fig. 1 to Fig. 6 and Fig. 7 a, 7b, 7c and Fig. 8 a, 8b, the capacitance plate class flexible circuit board measurement jig of the utility model one embodiment comprises: upper loading plate 1, lower bottom base 2, be arranged at of loading plate 1 and press down the card extender 7 that assembly 3, are connected in this lower platen 4 that presses down assembly 3, are arranged at a testing circuit board 5 on lower bottom base 2, are arranged at a capacitance plate body 6 on loading plate 1 and are electrically connected with this capacitance plate body 6.Wherein, this lower bottom base 2 is bases that whole tool is supported and can be for fixing test circuit board 5, this loading plate 1 is the supporting surface for test jobs is provided, press down assembly 3 for lower platen 4 is pressed down and lift operation, lower platen 4 is for pushing down the capacitance plate class flexible circuit board 8 of testing, one end (the crimping finger end 701 being connected with capacitance plate body 6) of card extender 7 is electrically connected on capacitance plate body 6, and the other end (the crimping finger end 704 of engaged test end) by this card extender 7 has been realized be connected (function served as bridge that plays conducted signal) of capacitance plate class flexible circuit board 8 and capacitance plate body 6 indirectly with the contact of the capacitance plate class flexible circuit board 8 of testing, testing circuit board 5 is connected with the tie point of capacitance plate class flexible circuit board 8 by lower platen 4 lower ends and test signal is passed to test computer and realizes the electric performance test of capacitance plate class flexible circuit board.
More specifically, on this, loading plate 1 is being positioned at the position of lower platen 4 lower ends, the pattern groove 101 that capacitance plate class flexible circuit board 8 profiles that offer and test and the degree of depth adapt, simultaneously, this pattern groove 101 is being provided with double-ended needle 102 corresponding to the crimping finger position of capacitance plate class flexible circuit board 8, and make to treat that the crimping finger of capacitance plate class flexible circuit board 8 of side and the crimping of the engaged test of card extender 7 finger end 701 are reliably to contact by double-ended needle 102, avoid location dislocation.
Wherein, the card extender 7 of this capacitance plate class flexible circuit board measurement jig carries out the main improvement of optimizing.Again consult shown in Fig. 7 a, 7b, 7c and Fig. 8 a, 8b, concrete: first, the crimping finger end 701 that this card extender 7 is connected with capacitance plate body 6 discharges stress problem for considering, is designed to have the structure of a breach, but not adopts the design of common flat side.Secondly, this card extender 7, for making card extender and capacitance plate body 6 can carry out accurate crimping, which is provided with 2 registration holes 703 to carry out contraposition.Again, this card extender 7 fully takes into account the contour length design load of card extender outer 7 can be stablized because of the product test of capacitance disturbing effect, and its contour length L is set as being not less than 70mm.And this card extender 7 affects product test stability for fear of being progressively out of shape in test process, it pastes one deck reinforcing chip 702(in crimping finger end 704 laminatings near engaged test end and preferably adopts the FR4 reinforcing chip that 1.0mm is thick).Finally, the wires design of card extender 7 is optimized, copper design is not covered at crimping that this card extender 7 is connected with capacitance plate body 6 finger end 701 back sides yet, and synchronous signal change-over terminal circuit girth designs short and logicalnot circuit zone design as far as possible and becomes to cover real copper and do.
