The 4th kind of improvement of the present invention is: described wafer 1 is 4.5mm*1.1 ~ 1.5mm wafer; Described base plate 8 is 2.8mm*6.8mm*0.7mm base plate, and the lead spacing between two fairlead I 8-1 is 2.5mm;
The wafer of 4.5mm length, reduces the contrived experiment difficulty of other wafer size of different frequent points, and has ensured unit for electrical property parameters, reliability and qualification rate;
Base plate 2.8mm width can meet the upper plate width requirement of 2*6 column crystal and meet air-tightness requirement (insulation resistance >=500M �� is more than 99.6%), the length of 6.8mm can assemble the wafer of 4.5mm length, and the base plate of 0.7mm thickness can ensure that air-tightness requirement; The lead spacing of 2.5mm can meet recommendation wicking pattern during the automatic upper plate of client.
Existing quartz-crystal resonator wafer is stood on pedestal, and the surface mounting quartz crystal resonator of the present invention, wafer is laid on pedestal.
The surface mounting quartz crystal resonator of the present invention, single armed elongates shell fragment can better discharge the spuious stress in crystal pro cessing process, for 12M, the DLD2 change that stress causes can be made to be accounted for 90% by former 9 �� MAX control to account for 90% at 6 �� MAX, improving concordance and the stability of product frequency and resistance, its data distribution CPK can be increased to more than 1.3 by former 1.1; Employing insulation spacer can be suitable for the installing space of the 2*6 product of client and can be coated with this product good, allows base plate insulate with stannum; The manufacture method of resonator of the present invention, wherein: rugosity: adopt sputtering mode, faster, silver layer is more firm for the speed more silver-colored than conventional vacuum evaporation; Added, some glue: adopt Japan's guide rail, two-sided Glue dripping head, efficiency is improved 1 times, for strict 1 grade of focus precision controlling. Manufacture method is simple, work efficiency is high, good product quality, low cost of manufacture.
