Description
Technical field
The invention belongs to technical field of electronic components, specifically disclose a kind of applied to the online of SAW filter
Method of testing.
Background technology
Fba wave filters are widely used in second, third third-generation mobile communication, remote control, telemetry and biochemistry, medical science etc.
Field, for research and development, there is also the problem of numerous urgent need to resolve with production unit for the test of Fba wave filters：
1) Fba wave filters, which are applied to research and development equipment, needs accurate research and development and strict guarantee, just can guarantee that the normal fortune of equipment
OK, this proposes new requirement to filters to test；The environment applied by wave filter is different, and the requirement to wave filter is not yet
Identical, the application environment of wave filter is more severe, and the parameter index of wave filter requires harsher, filters to test before application
More difficult complexity.Need to carry out the test under simulation low temperature (- 55 DEG C), high temperature (125 DEG C) so that Fba filters to test is more
It is complicated and cumbersome.
2) due to needing to carry out high/low temperature screening, and need to carry out the survey of Fba filter parameters under each temperature spot
Examination, so in the case where Fba wave filters quantity is relatively more, one side manual test efficiency is too low, it is necessary to substantial amounts of test, note
Record personnel, and progress manual operations is also very inconvenient under each temperature spot；Another aspect manual test is inevitable
The error that various human factors are caused is brought, is unfavorable for the guarantee of device parameter performance.It is required to filter large batch of Fba
Automatic test of the ripple device under analog temperature environment.
3) because the volume of Fba wave filters is very small, and manual clamping wave filter is to easily causing damage on jig plate,
Need to design a set of automated exchanged cutter system for being capable of automated exchanged cutter wave filter, so can not only reduce man power and material, and
Can be because of touching or other reasonses to the test of wave filter bring error into.
The detection and screening of wave filter now are roughly divided into two aspects：In a first aspect, under the normal temperature environment of wave filter
Detection and screening, detection and triage techniques comparative maturity under normal temperature have been carried out automated exchanged cutter and the blanking of wave filter, and
And wave filter is moved using the method for vacuum suction, the positioning of wave filter is also relatively more accurate,
But the test fixture under temperature test chamber one edition is manual test, not corresponding automatic charging machine, and
Also it is the mode of lead corresponding to the fixture one edition in temperature test chamber, and without the feeder for coordinating automatic charging equipment.
Filter detection and screening under high and low temperature environment is mainly for the aspect of research and production two：On the one hand, wave filter
Manufacturer during scientific research and testing are done, for the small volume of wave filter, the characteristics of pin is more accurate is kept away as far as possible
Exempt from its performance indications to compare because manually or because of the more harm of the damage ratio that misoperation is caused.In process of production,
Because filter specification is relatively more, it is required for being tested, the workload of test is very big.It is most widely used in particularly equipping
All kinds of intermediate frequencies, radio-frequency cable, quantity are very big, and this kind of cable influence of the performance indications to equipment performance characteristic again most
Greatly, index request is very high, and requires to test all parameters of each wave filter.Therefore, each wave filter producer
To can fast and flexible handling, efficiently and accurately, population parameter test is right during wave filter system, production, delivery etc. to meet automatically
The requirement that performance of filter is examined.
Existing technology combines corresponding jig Design automatic charging machine, is carried out under high/low temperature in automatic testing process,
Effectively avoid because of the error in the manually operated test parameter brought into or index, and manually operated bring into can be avoided
Physics hard defects, external error factors of the wave filter in high/low temperature test process are preferably minimized.
Due to introducing automatic charging machine, the testing efficiency in high/low temperature test process, and drop can be not only solved the problems, such as
Low human cost, reduction consumes the substantial amounts of time because of clamping, and differentiations can be identified automatically for automatic charging machine, reality
The detection and screening now automated.
The content of the invention
For above-mentioned technical problem present in prior art, the present invention proposes a kind of applied to SAW filter
On-line testing method, it is reasonable in design, the deficiencies in the prior art are overcome, with good effect.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of on-line testing method applied to SAW filter, using a kind of high-volume wide temperature range surface acoustic wave
