- FIG. 2B is a bottom view of the cancase with the optical filter 28 attached as seen from the opening side.
- FIG. 3 is a plan view of the pyroelectric infrared sensor 10 as viewed from the window side.
- the pyroelectric infrared sensor 10 shown in FIG. 1 includes a metal stem 12 and a metal can case 30.
- the stem 12 includes a disk-shaped support base (stem base) 12a.
- stem base 12a In the support base 12a, three terminal pins 14a to 14c are formed penetrating the support base 12a in the thickness direction. Among these, the terminal pins 14a and 14b are attached to the support base 12a (hermetically sealed) through the glass material 16, and the terminal pin 14c is directly attached to the support base 12a.
- a hook-like member for floating and supporting the alumina substrate 20 from the support base 12a is projected and formed in a direction perpendicular to the axial direction of the terminal pins 14a to 14c. ing.
- the FET 18 is attached to the lower surface of the alumina substrate 20.
- a plurality of predetermined electrode patterns 22 are formed on the alumina substrate 20.
- Each terminal of the FET 18 is electrically connected to each electrode pattern 22 of the alumina substrate 20.
- recesses 20a to 20c for fitting the terminal pins 14a to 14c are formed.
- the terminal pins 14a to 14c are fitted into the recesses 20a to 20c, and are electrically connected to and fixed to the electrode patterns 22 by a conductive paste or the like.
- a support base 24 having a substantially concave cross section is fixed to the upper surface of the alumina substrate 20.
- the support base 24 functions as a high resistance body for supporting the pyroelectric element 26 and obtaining an output voltage.
- the support table 24 is electrically connected to the corresponding electrode pattern 22 at both ends.
- the support 24 may be formed of a material such as borosilicate glass or alkali-free glass in that it has low thermal conductivity, mechanical strength, and a resistance value of about 10 11 ⁇ . preferable.
- a dual type pyroelectric element 26 is disposed on the upper surface of the support base 24.
- the vicinity of both ends in the longitudinal direction is fixed to and electrically connected to the convex portions 24a and 24a 'of the support base 24, respectively.
- a window 30W is opened in the can case 30, and the optical filter 28 is bonded to the window 30W.
- the opening of the can case 30 is resistance-welded to the outer peripheral portion of the support base 12a of the stem 12 so that the inside of the package is sealed.
- the can case 30 has an oval shape before being fitted into the support 12a of the stem 12 (single unit state).
- the support base 12a of the stem 12 is circular.
- the outer diameter of the support base 12a is smaller than the long diameter MAA of the opening 30A of the can case 30 and larger than the short diameter MIA.
- the opening 30A of the can case is fitted into the support base portion 12a of the stem. That is, the major axis of the opening 30A has a margin with respect to the outer diameter of the stem support base 12a, and the gap corresponding to the margin acts as a margin for shrinkage. Since the short diameter of the opening 30A is smaller than the outer diameter of the stem support base 12a, the support base 12a is sandwiched by this short diameter.
- FIG. 4 is a cross-sectional view showing a state when the can case 30 is fitted into the stem 12.
- This cross section is a plane passing through the short axis MIA shown in FIG.
- the support base 12a includes a tapered portion 12T that contacts the opening 30R of the can case, and a vertical portion 12V that extends from the tapered portion 12T to the flange portion of the stem 12.
- the inner peripheral edge 30R of the opening of the can case is rounded.
- the inner peripheral edge 30R of the opening of the can case slides on the tapered portion 12T of the support base portion 12a of the stem, and the shape of the opening that has been elliptical is changed to a circle. To do.
- the opening of the can case sandwiches the vertical portion 12V of the stem support base in the minor axis direction.
- the tapered portion 12T may have a round shape.
- the can case can be deformed and fitted into the stem simply by press-fitting the can case 30 into the stem 12.
- the opening 30A may be covered with the stem support base 12a in a state of being elastically deformed so as to be substantially circular. If the pressure is released, the can case also holds the stem support 12a due to its elasticity.
- the opening of the can case is fitted into the support base portion 12 a of the stem 12. Since the short diameter part of 30A elastically clamps the support base part 12a of the stem, it is possible to maintain the state in which the opening part 30A of the cancase is fitted in the support base part 12a of the stem 12, and to prevent a shift during storage.
- the deviation is suppressed when the can case opening 30A is set to the resistance welding electrode in order to resistance weld the outer periphery of the support base 12a of the stem. Therefore, the workability of resistance welding is improved. Furthermore, since the resistance welding is performed in a state where the stem 12 and the can case 30 are held at a predetermined fitting strength, they are prevented from being displaced by a shock during welding.
- the positioning during welding can be set up offline, the resistance welding work can be performed efficiently, and the tact of the equipment can be improved.
- FIGS. 2 and 3 show examples in which the entire cylindrical portion of the cancase is an elliptical cylinder. However, a cross-sectional view from the bottom (surface opposite to the opening) of the cancase to the opening is seen. In this case, even if the bottom is circular and the shape gradually becomes elliptical as it approaches the opening, the same effect is obtained.
- the pyroelectric infrared sensor shown in the embodiment is an example, and it goes without saying that the present invention can be applied to various electronic component can package structures including a stem and a can case.
