Description of the Invention [Technical Field] The present invention relates to a method of manufacturing an electronic component package and the like. [Prior Art] Various electronic components such as a quartz vibration element are housed inside an electronic component package, and various functional components such as quartz are housed. The electronic component package mainly includes a package body made of ceramic, a metallized region formed in the package body, and a seam ring fixed by solder in the metallized region. And a lid that is fixed by the seam by the seam of the seam loop. The package body is a box-shaped member, and has a concave portion for accommodating the functional member at the center. The metallized region is formed around the opening of the concave portion of the package body, and is formed by applying nickel (Ni) to tungsten or molybdenum. As shown in Fig. 1, in the case of manufacturing the electronic component package, a package-dedicated jig having a convex portion protruding upward from the susceptor is used. In the convex portion, the annular seam ring and the solder are first laminated in this order, and the concave portion of the package body is held downward, and the concave portion is fitted into the convex portion of the dedicated jig. Maintaining this state, if the solder is melted by heating the entire furnace, the seam ring is welded to the metallized area of the electronic component package. In addition, the special jig for packaging is made of carbon material in order to avoid attachment of solder during heating. In the recessed portion of the electronic component package body to which the seam ring is fixed, etc., the functional component is suitably disposed. If the lid portion is welded to the joint to seal the inner portion, the electronic component is completed. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei 8-46075. SUMMARY OF THE INVENTION [Problems to be Solved by the Invention] The miniaturization of electronic components is now progressing remarkably. As a result, the width dimension of the seam ring is also small. For example, there is also an electronic component having a size of about 0.2 mm to about 0.3 mm. If the width of the seam loop becomes smaller, it is necessary to increase the accuracy of the position of the seam loop of the package body (metallized region). However, in the prior manufacturing method, in order to realize the smooth mounting of the electronic component package, it is necessary to ensure a certain degree between the convex portion of the special jig and the seam ring and between the convex portion and the concave portion of the package body. There is a gap, and there is a problem that it is difficult to improve the accuracy of the position determination. In addition, in the mass production of electronic component packaging, an intermediate flat material (so-called collective substrate) before being divided into package bodies is used. That is, the intermediate flat material is cut and fixed for the intermediate flat material having a plurality of concave portions formed in the ceramic flat plate, and then the intermediate flat plate material is cut to obtain an electronic component package. In this case, the special jig is also necessary as a structure for the intermediate flat material. It is necessary to have a plurality of convex portions corresponding to the respective concave portions of the intermediate flat material. In the mass production project, in the state where the joint ring of the special jig is provided with the seam ring and the solder, the intermediate flat material is fitted from above to maintain the state and is carried into the heating furnace to concentrate the seam ring-5- 200917428 Fixed. However, this intermediate flat plate material is caused by a large number of shapes due to shrinkage during firing due to shrinkage during firing, and the gap between the concave portions and the convex portions of the intermediate flat plate material is first given. Increase the setting, or classify the intermediate plate error, and need to prepare the corresponding level in advance. In short, the installation accuracy is deteriorated and the manufacturing cost is increased. Further, these special jigs are worn by the contact of the package body or the seam ring due to the carbon material, and the heterogeneous ring cannot be properly welded, and the manufacturing quality is lowered. In view of the above problems, the object is a quality, and it is also possible to soften the method of manufacturing a miniaturized electronic component.

The seam welding roller unit 5 A has a freely rotating welding roller 5 E. Further, the vertical slider 5 C is particularly provided with a pressing means such as a spring (not shown), and the welding roller 5E is pressed against the collective substrate 50 with a specific weight. Therefore, when the collective substrate 5 is deformed and an error occurs in the fixed state of the electronic component package, each of the welding rollers 5E moves up and down to absorb the error. Therefore, the welding ring 5E is brought into contact with the seam ring 5 4 ′ mounted on the collecting substrate 50 to heat the joint of the seam ring 54 and the welding roller 5 E by flowing a welding current. The solder 52 in the vicinity of the contact is partially melted. As a result of this, the seam ring 54 is partially welded to the metallized region 50B of the collecting substrate 50. The heating furnace 6 corresponds to the heating means for ring fixing of the present invention, and the collective substrate 50 of the temporarily fixed seam ring 54 is housed and heated as a whole. As a result, the solder 52 is entirely melted, and the entire circumference of the seam ring 54 is completely welded to the metallized region 50B by the solder 52. The spacer cover 7 covers the periphery of the collective substrate mounting stage 2, the solder arrangement arm 3, the ring arrangement arm 4, the spot welding device 5, and the like. Nitrogen is introduced into the inside of the separation cover 7, and the vicinity of the collective substrate mounting platform 2 is placed in a nitrogen atmosphere. Thereby, at the time of spot heating, it is suppressed that the metallized region 50B or the seam ring 54 is oxidized. Next, referring to Fig. 2 and Fig. 3, the electronic component package 60 ° electronic component package 60' is provided with a ceramic package body 62, a solder 5, and a seam ring 504. The ceramic package body 6 2 is an intermediate flat material -10- 200917428 The collective substrate 50 is divided into a cubic shape, and a concave portion 50A is formed on the surface of the six faces. Around the opening of the recess 5A, a metalized region 50B having a rectangular ring shape is formed. The metallized region 5〇b is made of a metal material such as tungsten or molybdenum, and nickel plating is applied thereto. Further, the size of the ceramic package body 62 is preferably such that the longitudinal direction is 2 5 mrn and the width direction is about 2.0 mm or less. The solder 52 can be selected from a wide variety of materials depending on the melting point, but for example, a Cu-Ag material melted at 850 degrees can be used. For example, Sn-Ag material, Pd_Sn material, Au_Sn material, Cu_Ag_In material, etc. may be selected. This solder 52 is bonded to the shape of the metallized region 5〇B to form a rectangular ring-shaped flat plate material. The seam ring 54' is a metal ring having a diameter of 0.2 to 0.3 mm of a Koval material, and is obtained by applying nickel plating. This seam ring 54 is sized to coincide with the metallized area 50B. As shown in Fig. 3, the collective substrate 50 which is the intermediate sheet material of the ceramic package body 62 is formed in a single ceramic sheet, and a plurality of concave portions 50A are formed in a matrix shape. Further, as described above, the metallized region 5 0 B is formed around the concave portion 5 〇 a (not shown in Fig. 3). The metallized region 50B is formed by printing a metal material at a thickness of 7-14 "m and heating it to about 1300 degrees. Further, between the arrangement of the recesses 50 A, the dividing groove 50c is formed in a mesh shape, and an external force is applied to be broken along the groove 50C. Further, as will be described later, the seam ring 54 is fixed to the collective substrate 50 in advance. Therefore, if the collective substrate 50 is divided along the groove 50C, the electronic component package 60 in which the seam ring 54 is fixed in advance can be obtained. Next, a method of manufacturing the electronic component package 60 using the manufacturing apparatus 1 will be described. First, in the preparation step shown in the state of Fig. 4(A), the concave portion 50A is a collective substrate 5 that is opened upward, and is positioned and fixed to the collective substrate. Above the platform 2. Further, the periphery of the collective substrate mounting stage 2 is first used as a nitrogen atmosphere. Thereafter, in the solder disposing step shown in Fig. 4(B), the solder 52 is placed by the solder, and the solder 52 is positioned and disposed in the metallized region 50B. The positioning of the solder 52 is performed, for example, by irradiating a flash to the metallized region 50B, and photographing the reflected light by the position detecting portion 3D to accurately position and angle the metalized region 50B. Detection. Next, in the ring arrangement step shown in the state of Fig. 5(A), the seam ring 4 is placed on the solder 52 by the ring arrangement arm 4, and is placed. This positioning is also performed in the same manner: the position of the metallized region 50B and the solder 52 is detected with high accuracy by the position determining detecting portion 4 D. Thereafter, in the ring temporary fixing step shown in the state of the fifth (B) diagram, the welding roller 5 E of the spot welding device 5 is lowered, so that the welding roller 5 E abuts against the opposite sides of the seaming ring 5 4 . At this time, the welding roller 5 E is not moved as much as possible, and a pulse current of about 100 to 150 A as a welding current flows through 3 to 6 milliseconds. As a result, the joint between the seam ring 54 and the welding roller 5E is heated in a dot shape, and the solder 52 in the vicinity thereof is melted. Thereafter, the welding current is stopped. If the seam ring 54 is raised, the solder 52 is solidified by -12-200917428 and partially welded to the metallized region 50 and the seam ring 54. By thus determining the state of the position with high precision, a part of the solder 52 can be made "wet state" while the seam ring 54 is positioned in the metallized region 50. The solder arrangement step and the ring arrangement step temporary fixing step are performed in reverse for each concave portion 50A region 50B of the collective substrate 50, and the slit ring 54 is temporarily fixed in all the metallized regions 50B. Thereafter, in the ring fixing step, the seam ring assembly substrate 50 is temporarily fixed and carried into the heating furnace 6 to heat the entire portion. When the temperature is raised, the solder 5 2 is temporarily fixed, and the portion which becomes 濡 is melted as a starting point (trigger), and the wetness spreads in an all-round manner. In particular, between the seam ring 54 and the metal 50B, the surface tension is exerted, so the position of the natural precision is determined. Thereafter, the furnace 6 is gradually lowered while the air bubbles contained in the inside of the solder 52 are degassed while being solidified. As a result, the entire circumference of the seam ring 54 is welded to the metallized area. Thereafter, the collective substrate 50 is divided to obtain the seamed-ring electronic component package 60. According to the present embodiment, the seam ring 54 is temporarily fixed with high precision, and then the entire circumference can be fixed by the heating furnace 6 to fix the seam ring with high precision for the metallized region 5 Ο B. In the ring temporary fixing step, a part of the solder 52 is "sweetened", and then the entire furnace is heated by the heating furnace 6, so that the wet state is expanded to a state of being wet to the whole state as the starting point, and is temporarily fixed. The metal of the so-called ring and the ring is connected to the temperature of the ultra-wet state to achieve a high temperature, and the cooling zone 50B [54 is positioned to become 5 4 . In addition, as a high-quality welding quality, it can be mentioned as -13- 200917428. As a result, the yield at the time of manufacture can be improved. Even if the sub-part package has been miniaturized, the part package 60 can be manufactured with high precision. Further, in the present embodiment, as shown in Fig. 6(A), the intermediate portion X of the two sides of the seam ring 54 is added to the metalized region 50B, but the present invention is applied. It is also preferable that the corner portion Y of the square seam ring 504 is heated and temporarily fixed as shown in Fig. 6(B). Since the plating region 50B is applied to the surface of the package body, the corner portion is easily raised due to the surface or the like. Thus, if the seam ring 54 is welded to the portion (corner portion) of the metallized region 50B, the tentative state of the seam ring 54 can be stabilized. Further, in the present embodiment, the pair of welded portions 5 E are arranged such that the inner side has a small diameter and the outer side has a large diameter. However, as shown in Fig. 7, the inner side is made larger in diameter. The situation with small diameter on the outside is also ideal. In such a manner, the side of the diameter of the welding rim can be made larger, and the inside of the recessed portion 50 Α can be surely prevented from coming into contact with the substrate 50. Further, in the present embodiment, the present invention is limited to the case of using the collective substrate 50 and the electronic component package 60. However, the present invention is not limited thereto, and the package body 62 may be soldered to the package body 62 which has been previously divided. In this case, as shown in Fig. 8, it is preferable to use a tray 70 on which the plurality of packages 62 can be mounted. The positioning of the tray 70 is 70A, and the package body 62 is provided. In the case of the collective substrate 50, the electronic timepiece is not hot. Therefore, when the metal tension is thick, the solid roller is straight: 5E running, manufacturing limitation The seam ring body recess is the same as 200917428. The seam ring 54 can be fixed to the package body 62. Further, in the present embodiment, the present invention is limited to the case where the concave portion 50A is formed in the seal 62, but the present invention is not limited thereto. In the case of the miniaturization of the electric components of the year, as shown in Fig. 9, the body 62 (or the collecting substrate 50) is formed of a flat plate material to form the annular metallized region 50B of the package body 62 via the solder 52. It is also preferable that the sewing ring 54 is fixed. By the thickness of the seam loop 54, the recess is substantially. Further, in the present embodiment, the seaming ring 54 is temporarily placed in the metallized region 50B, and the joint welding type is used. However, the present invention is not limited thereto, and irradiation by laser or the like is used. Heating and welding are also good. That is, in the present invention, if the seam ring 54 can be heated to wet the solder 5 2, it can be selected. Further, in the present embodiment, the heating ring is used when the seam ring 54 is timed. However, the present invention is not limited thereto, and other heating means are used for heating. Further, in the present embodiment, the solder 5 2 is placed on the metallized region 5 0 B and then placed on the slit ring 5 4 . However, the present invention is not limited thereto. As shown in Fig. 10 (A), when the solder ring 5 2 is applied to the seam ring 5 4 , the 5 4 is directly placed on the metallization as in the 10th (B) diagram. Area 5 0 B is also good. When the spot is heated to i, the solder 52 is melted, and the seam ring 54 is welded to the metallized region. In addition, the electronic component package manufacturing method of the present invention, etc., is set in the above embodiment, and the present invention is not detached. The main body of the package is the near-package body, and the fixed-welding device can be fixed at the point where the connection can be formed. The final assembly can be carried out. For example, the coating seam ring is 54 54B. . However, it is not limited to -15- 200917428 and various changes are made. [Industrial Applicability] The present invention can be widely utilized in the field of manufacturing electronic parts.
