Description
Technical field
The utility model belongs to the tool technical field of making quartz crystal unit, specifically washes tool after a kind of small-sized quartz-crystal resonator screening.
Background technology
Along with the quartz crystal components and parts constantly to miniaturization, high accuracy, high stability future development, the quartz crystal wafer size is more and more less, directly uses silver-plated tool screening difficulty to strengthen, it is poor that wafer is aligned to bit rate, loss is serious.Secondly, wafer in silver-plated mask plate, then carries out secondary cleaning together with silver-plated tool at silver-plated front row, and this step operation is called " washing afterwards ".After need carry out centrifuge dripping after washing, wafer is easily escaped sheet in the magnetic tool, cause silver-plated rear electrode fraction defective to raise.Moreover, because the repeatedly sputter of silver-plated tool uses, its surface can produce the silver bits after wash in the process to shake through ultrasonic wave and wash, the silver bits have unavoidably and come off, thereby cause the pollution of cleaning fluid and wafer, (large such as the frequency scattered error, impedance is higher in silver-plated rear electrical characteristic to make wafer, level of drive dependence variation etc.) be affected, thereby reduced crystal qualification rate and stability.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can solve effectively that the screening arrival rate is low, silver-coated electrode is bad, rear contaminate dyes and causes washing tool after the unsettled small-sized quartz-crystal resonator screening of electrical characteristic.
The utility model is realized by the following technical solutions:
Wash tool after a kind of small-sized quartz-crystal resonator screening, comprise base plate, upper cover plate, fixed screw, the shape that it is characterized in that base plate and upper cover plate is identical with actual silver-plated tool, have wafer to place groove on the base plate, be used for placing wafer, corresponding upper cover plate is with wafer screens projection, base plate engages by concavo-convex with upper cover plate, and fix by fixed screw, wafer is placed groove has the slit with wafer screens projection Intermediate Gray, and wafer screens projection centre is with aperture.After being placed into wafer in the base plate wafers placement groove during operation, upper cover plate and base plate are closely linked by concavo-convex, then use described fixed screw locking, make wafer be difficult for skidding off in wafer is placed groove.After when washing cleaning fluid can place the intermediate gap of groove and all through holes on the tool by wafer and carry out ultrasonic wave and shake and wash, to reach the effect of again cleaning.
The utility model adopts technique scheme, can improve the wafer screening and be placed into bit rate, reduce manually and revise, after wash and can also reduce the silver bits in the process and pollute, reduce wafer and escape sheet, greatly improved the stability of wafer utilance and product electrical characteristic.
