Problems solved by technology

[0006] However, it is generally believed that the following connection method is better, that is, the two substrate-side conductor patterns with an interval of Y1 are connected to the quartz crystal vibrator in the form of support on both sides of the quartz sheet 5. However, the quartz crystal vibrator 1 needs to be installed here. The quartz crystal vibrator 1 can vibrate according to the characteristics of the cantilever support form, and the quartz crystal vibrator in the form of support on both sides cannot be used

Embodiment Construction

[0029] Refer to Figure 1- Figure 4 , taking the quartz crystal resonator as the first embodiment of the present invention as an example, a small electronic component constructed according to the present invention will be described. As the quartz crystal resonator 10 of the first embodiment, the quartz thin slice 12 can be hermetically sealed inside by using the base 14 and the cover 16 , and can be installed on the substrate 18 for use. 1(A) is a schematic plan view showing the quartz crystal resonator 10 when the cover 16 is not installed, and FIG. 1(B) is a schematic cross-sectional view showing the quartz crystal resonator 10 viewed along the IB-IB direction.

[0030] Base 14 can be as shown in Fig. 1 (A) and Fig. 1 (B), and its plane shape is substantially rectangular (the longitudinal length A2 of base 14 and cover body 16 is about 3.2 millimeters, and transverse length B2 is about 5.0 millimeters) , and formed into a cup shape open toward the upper side. As shown in F...

Abstract

Provided is small electronic element, including a conductor pattern 36 which is formed on the 1st terminal 28, an insulation part 32 and a 1st insulation film 34, and a 1st part 36a of the conductor pattern 36 is electrically connected to the 1st terminal 28. The 1st terminal 28 is electrically connected to a substrate side conductor pattern 48 formed to a substrate 18. A crystal chip 12 is supported by a 2nd part 36b while being electrically connected to the 2nd part 36b of the conductor pattern 36. Thus, by forming the conductor pattern 36 to locate the 1st part 36a and the 2nd part 36b at desired positions on a base 14, a support position of the crystal chip 12 can be determined independently of the installed position of the 1st terminal 28 connected to the substrate side conductor pattern 48.

Description

technical field [0001] The present invention relates to small electronic components, and particularly to small electronic parts such as quartz crystal oscillators, quartz crystal oscillators, SAW filters (comb filters), piezoelectric tuning forks, piezoelectric vibrators, etc., which are hermetically sealed inside. part. Background technique [0002] A small electronic component in the prior art, such as Figure 11(A) ~ Figure 11(C) The quartz crystal resonator 1 shown has been disclosed in Japanese Invention Patent Application Publication No. 344979 / 2000 (H03H9 / 00). FIG. 11(A) is a schematic top view of the quartz crystal vibrator 1 when the cover 2 is not installed, and FIG. 11(B) is a schematic cross-sectional view showing the quartz crystal vibrator 1 viewed along the XIB-XIB direction. FIG. 11( C) is a schematic cross-sectional view showing the quartz crystal resonator 1 viewed along the XIC-XIC direction. This quartz crystal vibrator 1 has a base 4 made of a conducti...
