Technical Field

The utility model belongs to the technical field of the electronic module detects, concretely relates to pressure sensor electronic module structure.

Background

Because the pressure sensor electronic module models are more, each model calibration needs to develop a set of calibration equipment, one equipment is higher in price, each model develops a set of calibration equipment, and the equipment investment is larger. The second time, too many equipment are invested, and the maintenance is inconvenient. Therefore, a universal calibration scheme is needed to be designed, which is suitable for different machine types and shares one set of calibration equipment.

SUMMERY OF THE UTILITY MODEL

Therefore, the to-be-solved technical problem of the utility model is to provide a pressure sensor electronic module structure, same calibration equipment can be applicable to the use of multiple model, and the commonality is strong.

In order to solve the problem, the utility model provides a pressure sensor electronic module structure, which comprises a circuit board, be equipped with sensor and test point on the circuit board, the test point is established the border position of circuit board, the test point with the sensor is connected.

Preferably, the test points include at least four: VDD supply, GND ground, OUT output, VPP calibration.

Preferably, the sensor is provided in plurality and arranged in the middle of the circuit board.

Preferably, each sensor corresponds to at least four test points: VDD power supply, GND ground, OUT output, VPP calibration; all the test points are arranged on the edge of the circuit board.

The utility model provides a pair of pressure sensor electronic module structure, which comprises a circuit board, be equipped with sensor and test point on the circuit board, the test point is established the border position of circuit board, the test point with the sensor is connected. The calibration detection of the pressure sensor basically only involves the connection of the test point and the calibration equipment, and the test point is connected to the edge position of the circuit board where the pressure sensor is located by the structure, so that the test point can be conveniently clamped by the same clamp to test circuit boards of different models, and the production efficiency is improved.

Fig. 1 is a schematic diagram of a pressure sensor electronic module structure according to an embodiment of the present invention.

The reference numerals are represented as:

1. a circuit board; 2. a pressure sensor; 3. a VDD power supply test point; 4. a GND ground test point; 5. OUT output test points; 6. the VPP calibrates the test points.

Detailed Description

Referring to fig. 1 in combination, according to the embodiment of the present invention, a pressure sensor electronic module structure, includes a circuit board 1, a sensor 2 and a test point are arranged on the circuit board 1, the test point is arranged at the edge of the circuit board, and the test point is connected to the sensor.

All used calibration test points of the pressure sensor electronic modules on the whole PCB are placed on two sides of a PCB jointed board, the arrangement sequence, pin definition and position of each test point are fixed, the electronic modules are connected with the test points through wires, and the pin definition of the calibration test points on the electronic modules of different models is universal, so that the pressure sensor electronic modules of different models can adopt the design scheme, and the calibration clamp can be shared among different models as long as the positions of the test points are all kept consistent and the pin definition is arranged according to the same sequence.

The structure has the advantages that the universal use of the calibration fixture can be realized, the large investment of calibration equipment is saved, and the production cost is saved; when different types of products are produced, the calibration clamp does not need to be frequently replaced, and the production efficiency is improved

Preferably, the test points include at least four: VDD supply 3, GND ground 4, OUT output 5, VPP calibration 6.

Preferably, each sensor corresponds to at least four test points: VDD supply 3, GND ground 4, OUT output 5, VPP calibration 6; all the test points are arranged on the edge of the circuit board.

Since a pressure sensor product typically has 4 test points for it: a VDD power supply test point 3, a GND ground test point 4, an OUT output test point 5 and a VPP calibration test point 6; all the four test points are connected to the board edge test points through leads, and are arranged into an upper row and a lower row as shown in figure 1; different sensors are different in size, but the four test points are the same, and the common calibration tool can be realized only by connecting the corresponding four test points to the board edge test points and enabling the positions of the four test points to be all corresponding to each other.

It is easily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
