Abstract
The utility model relates to a pressure sensor system module, comprising a PCB plate, a capacitance and a terminal, wherein, a protective frame made of plastic material and a bare chip are arranged on the surface of the PCB plate, and the bare chip is fixed on the surface of a bare chip hold-down groove at the inner side of the protective frame. The data of all characteristic parameters required by the pressure sensor is solidified in the bare chip; a wiring unit connected with the bare chip by a lead wire is arranged at the two sides of the bare chip; and protective glue which is made of transparent pasty material and used for protecting the bare chip is injected into the protective frame. The pressure sensor system module has simple and reasonable designing structure and processing technique, and can improve the service efficiency of the product and the finished product qualification rate, lower the production cost of the product, and ensure the system output to have excellent linear precision and temperature compensation.
Description
Technical field
The utility model relates to a kind of device for vehicular electronic, especially a kind of pressure sensor systems module.
Background technology
Existing automobile-used pressure transducer product, generally be that needs according to the client design voluntarily with customization and finish, need elements such as institute's pressure-sensing device, data conditioning chip, EMC electric capacity are individually fixed in special-purpose pcb board surface, this module assembling is finished, and then need module is connected with outside terminal, enclosed package is just finished the final products assembling.Carry out staking-out work at last,, can normally use the own needed chip internal that has the data input module of special parameter.Yet, because the project organization of existing automobile-used pressure sensor module self and processing technology are comparatively complicated, the staff causes damage easily owing to maloperation in to the element assembling process, thereby has reduced the lattice rate of finished product, the processing cost when having improved production; In addition, again because the complicacy of existing automobile-used pressure sensor calibrating work if misoperation also reduces production efficiency of products and functions of use easily, thereby can't reach the result of use of customer satisfaction.
The utility model content
For solving the problem of above-mentioned existence, the utility model provides a kind of project organization and processing technology advantages of simple, can improve product service efficiency and product qualified rate, reduces a kind of pressure sensor systems module of production cost.
For achieving the above object, the utility model provides a kind of pressure sensor systems module, comprise pcb board, electric capacity and terminals, described electric capacity and described terminals all are arranged at the surface of described pcb board, described pcb board surface also is provided with nude film and protection frame, and described Naked sheet is fixed in the nude film pickup groove surface of the inboard of described protection frame.
Described protection frame adopts plastic material to make, the inboard protection glue that is used to protect described nude film that also is marked with.
The material that described protection glue is paste and transparence constitutes.
The described PBC surface of described protection scuncheon also is provided with the wiring units that is connected with described nude film by lead-in wire.
Described nude film inside solidification is useful on the data of the required complete characteristic parameter of pressure transducer.
Described terminals also are connected by the control terminal of lead-in wire with the external world.
Compared with prior art, the utlity model has following advantage:
The pressure sensor systems module that the utility model provides, comprise pcb board, electric capacity and terminals, also be provided with protection frame and the nude film that adopts plastic material to make on the surface of pcb board, nude film is fixed in the Naked sheet pickup groove surface of the inboard of protection frame, and Naked sheet inside solidification is useful on the data of the required complete characteristic parameter of pressure transducer.The both sides of nude film also are provided with by the connected wiring units that goes between, and also are marked with the protection glue that the material that adopts paste and transparence constitutes, is used to protect nude film in the inside of protection frame.The utility model project organization and processing technology advantages of simple, can improve product service efficiency and product qualified rate, reduce the production cost, guarantee that also system's output has good linear precision and temperature compensation.Because nude film inside has been solidified with the required whole output characteristics parameters of pressure transducer, the client only needs the terminals of pcb board one end are connected with outside terminal, carries out enclosed package and can form product complete, that possess whole output characteristics.
Description of drawings
Fig. 1 is the utility model plan structure figure;
Fig. 2 is the utility model sectional structure chart.
The main element symbol description is as follows:
3 Naked sheets, 4 protection glue
5 electric capacity, 6 terminals
7 wiring units, 8 lead-in wires
Embodiment
Fig. 1 and Fig. 2 are respectively that the utility model is overlooked and cross-sectional view, mainly comprise pcb board 1, protection frame 2, nude film 3 and protection glue 4.The uper side surface of pcb board 1 is provided with electric capacity 5 and terminals 6, and this electric capacity 5 adopts the mode of welding to be fixed in an end on pcb board surface with terminals 6, also adopts the mode of welding to be connected between one group of electric capacity.Terminals 6 by lead-in wire (among the figure describe) thus be connected with the control terminal in the external world.Also be provided with employing on the other end surface of pcb board and have the protection frame 2 that high protective plastic material is made, the pcb board surface of protection frame 2 inside also is provided with nude film pickup groove (not describing among the figure) and wiring units 7, Naked sheet 3 is fixed in the uper side surface with the nude film pickup groove, and wiring units 78 is connected with nude film 3 by going between.Inside at the protection frame also is marked with the protection glue 4 that is used to protect the Naked sheet; protection glue 4 adopts the material of paste and transparence to constitute; this kind protection glue not only can increase the connectivity of Naked sheet and pcb board, the sensitivity that can also improve Naked built-in testing ambient pressure effectively.Nude film inside solidification of the present utility model has the required whole output characteristics parameters of pressure transducer, and the client need not chip internal to be carried out the input service of data again, and the staff can use after finishing installation, thereby has improved the convenient condition when using.
The utility model project organization and processing technology advantages of simple, can improve product service efficiency and product qualified rate, reduce the production cost, guarantee that also system's output has good linear precision and temperature compensation.Because nude film inside has been solidified with the required whole output characteristics parameters of pressure transducer, the staff is after the assembling of finishing this module, only need the terminals of pcb board one end are connected with outside terminal, carry out enclosed package and can form product complete, that possess whole output characteristics.
More than disclosed only be several specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
