Quartz wafer film coating jig
Technical field
The utility model relates to quartz products manufacturing fields, more particularly to a kind of quartz wafer film coating jig.
Background technique
In recent years, quartz products were increased in global annual sales by 15% or so speed.With information industry
Rapid development, piezoelectric quartz device are answered extensively because of its small in size, light-weight, high reliablity and the high feature of frequency stability
For in the various smart machines such as various industrial equipments, communication equipment, game station, housed device.
Quartz-crystal resonator is that one kind made of the piezoelectric effect using quartz crystal (crystalline solid of silica) is humorous
Shake device, its basic structure cuts thin slice by certain azimuth generally from one piece of quartz crystal, and (referred to as chip, it can
To be square, rectangle or circle etc.), on its two corresponding surfaces then plating coating metal layer will be coated with electrode as electrode
Chip be pasted on bracket by dispensing fixture insulating cement, conductive silver glue, allow plating metal chip to be fixed on two lead of bracket
Between, it connect its double-sided electrode with two lead of bracket respectively, along with package casing just constitutes quartz-crystal resonator, letter
Referred to as quartz crystal or crystal, crystal oscillator.Its product generally uses packed by metal casing, can also use ceramic package.
Plated film is one of the important procedure of quartz-crystal resonator production, and the lower process of automation.It acts as
The metals such as Cr, Ag are plated on chip two sides, form electrode.Since manual operation content is more herein, plated in crystal oscillator industry
Film production capacity is always the bottleneck production capacity of production line.
Piezoelectric quartz resonator manufacturer uses the coating clamp of two kinds of shapes substantially at present, as depicted in figs. 1 and 2.
Fig. 1 is suitable for evaporating coating technique, and the i.e. plate clamp of the station quantity of fixture carries the quantity of product on 120 left sides
The right side so causes production efficiency low.In addition, since the power-on and power-off pole plate of evaporation process itself and evaporating coating fixture separates
The reason of design, be easy to cause thickness of electrode uneven or upper/lower electrode thickness difference, it is easy to unstable quality after plated film is caused,
It in turn results in that product frequency error is larger, can generally there is the scattered error of -300 ~ -3500PPM.
Coating clamp provided by Fig. 2 is suitable for sputter coating process, since sputter coating process needs a bracket,
Coating clamp needs the mode being bolted to be fixed on bracket, and bracket is square structure, therefore, resonator factory
Family can generally design new coating clamp when using sputter coating process, and a bracket usually carries 3 ~ 5 coating clamps, this
Kind fixture equally causes the rising of cost and improved efficiency is not obvious.In addition, coating clamp in design or along to
The thinking that front upper and lower electrode plate separately designs, therefore the problem of equally exist unstable quality.
