Problems solved by technology

However, in the use of this directional sensor while drilling, due to the large vibration, the package is more likely to be peeled off, which will cause the entire directional sensor to fail.
In addition, the traditional directional sensor often integrates the transmitting chip and the receiving chip, and the transmitting signal and the receiving signal are prone to crosstalk

Embodiment Construction

[0036] The idea of ​​the present invention is to design an orientation-while-drilling sensor that prevents crosstalk and warpage and avoids chip peeling. Examples will be described in the following.

[0037] see figure 1 , the directional sensor while drilling of the present invention, it comprises:

[0038] The heat dissipation substrate 1 has a first surface and a second surface opposite to each other, and as a preference, it can be a ceramic substrate or an insulating substrate with a copper layer on the second surface to improve heat dissipation. A circuit layer (not shown) and a raised partition wall 2 are arranged on the first surface, and the circuit layer is embedded in the heat dissipation substrate 1 and is flush with the first surface; the circuit layer Grooves are realized by laser grooving process and then filled with copper.

[0039] A rubber buffer layer 4 is disposed on the first surface, and the rubber buffer layer 4 is provided with an opening to expose th...

Abstract

The invention provides a directional sensor while drilling and a manufacturing method of the directional sensor while drilling. The top end of a partition wall and the top surface of a shell are spaced by a certain distance, so that the crosstalk between a transmitting signal and a receiving signal reaches the minimum, and it can be known that filling of protective resin becomes easy due to the spacing of the partition wall; the chip is fixed more firmly through the L-shaped fixing piece, and the heat conduction can be enhanced; in addition, a plurality of second through holes can prevent the substrate and the packaging body from warping.

Description

technical field [0001] The invention relates to the field of semiconductor device packaging, in particular to the field of sensor packaging, and relates to a sensor and a manufacturing method thereof. Background technique [0002] With the continuous development of the petroleum industry and the increasing difficulty of oil and gas exploration and development, the petroleum exploration and development industry has gradually shifted to developing reservoirs with smaller scale, thinner oil layers, poorer physical properties and strong heterogeneity. The application of special technology wells such as flat wells is increasing year by year. During the construction of these special technology wells, it is necessary to grasp the properties of the rock formation drilled by the drill bit in time, and quickly and accurately find the reservoir, so as to guide the construction personnel to control the drill bit to always travel through the reservoir. , in order to maximize recovery, th...
