Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments.

[0011] Referring to FIGS. 1 to 3, the device tray 101 in some embodiments of the present invention will be described. The device tray 101 includes a plurality of first strip members 102 extending parallel to one direction (X direction), and a plurality of second strip members 103 extending parallel to a direction (Y direction) intersecting the plurality of first strip members 102. The plurality of second strip members 103 are arranged on the plurality of first strip members 102 (Z direction). Each of the plurality of accommodating portions 104 is formed so as to be surrounded by two adjacent first strip members among the plurality of first strip members arranged in parallel and two adjacent second strip members among the plurality of second strip members arranged in parallel. A device 105 can be accommodated in each of the plurality of accommodating portions 104. The end portion 106 of each of the plurality of first strip members 102 does not extend outside the device tray 101 beyond the corresponding second strip member. Similarly, the end portion of each of the plurality of second strip members 103 does not extend outside the device tray 101 beyond the corresponding first strip member. Thus, since the end portion 106 of each first strip member 102 and the end portion of each second strip member 103 do not extend beyond and protrude from the corresponding second strip member and first strip member, respectively, there is no incomplete accommodating portion for the device 105 on the outer periphery of the device tray 101, and the device 105 is not caught by the end portion 106 of each first strip member 102 and the end portion of each second strip member 103. The device tray 101 can sufficiently shake off the device 105, and can prevent injury to the user of the device tray 101 and / or damage to the device tray 101 itself caused by the end portion 106 of each first strip member 102 and the end portion of each second strip member 103.

[0012] In FIGS. 1 to 3, the intersection angle between the plurality of first strip members 102 and the plurality of second strip members 103 is approximately 90°, but the intersection angle may be set according to the specific use of the device tray 101. For example, the intersection angle may be set according to the shape of the device 105 accommodated in the accommodation portion 104 of the device tray 101. Also, the intervals between two adjacent first strip members and the intervals between two adjacent second strip members may be set according to the specific use of the device tray 101.

[0013] The contour of the device tray 101 is not limited, but from the viewpoint of improving the spoiling resistance of the device tray 101, as shown in FIG. 3, the device tray 101 may have a generally linear contour 107 at least in part when viewed from above the device tray 101. Also in this case, the device tray 101 includes a plurality of first strip members 102 extending parallel to one direction (X direction) and a plurality of second strip members 103 extending parallel to the direction (Y direction) intersecting the plurality of first strip members 102. The plurality of first strip members 102 have a first angle 108 with respect to the generally linear contour 107, and the plurality of second strip members 103 have a second angle 109 with respect to the generally linear contour 107. The first angle 108 may be an angle between 100° and 170°, and the second angle 109 may be an angle between 10° and 80°. Conversely, the first angle 108 may be an angle between 10° and 80°, and the second angle 109 may be an angle between 100° and 170°. Further, the first angle 108 may be an angle between 25° and 65°, and the second angle 109 may be an angle between 115° and 155°. Thus, by providing angles to the plurality of first strip members 102 and the plurality of second strip members 103 with respect to the generally linear contour 107, the strength and / or thermal shock resistance of the device tray 101 can be enhanced.

[0014] The device tray 101 may further include a plurality of third strip members 111 that extend parallel to each other in a direction (Y direction) parallel to the plurality of second strip members 103. The plurality of third strip members 111 are disposed below (in the Z direction) the plurality of first strip members 102. Each end of the plurality of third strip members 111 also does not extend outside the device tray 101 beyond the corresponding second strip member. When there is no other strip member below the plurality of third strip members 111, that is, when the plurality of third strip members 111 are the strip members disposed at the lowest position, the bottom 112 of the lower portion in the Z direction, which is opposite to the upper portion in the Z direction where the plurality of first strip members 102 are disposed, of each of the plurality of third strip members 111 may be flat. In this way, by making the bottom 112 of the plurality of third strip members 111 disposed at the lowest position flat, the device tray 101 can be stably disposed on a heating device or the like. Also, when there is no other strip member below the plurality of third strip members 111, the plurality of third strip members 111 may be disposed so as to pass below the accommodating portion 104 so as to support the device 105 accommodated in the accommodating portion 104. Further, the number of the plurality of third strip members 111 may be greater than the number of the plurality of first strip members 102 and / or the number of the plurality of second strip members 103.

[0015] In terms of improving the storage capacity of the device tray 101, the device tray 101 may further include a plurality of fourth strip members 113 extending parallel in a direction (X direction) parallel to the plurality of first strip members 102. The plurality of fourth strip members 113 are arranged on the plurality of second strip members 103 (Z direction). Each end 114 of the plurality of fourth strip members 113 also does not extend outside the device tray 101 beyond the corresponding second strip member. Further, the device tray 101 may further include a plurality of fifth strip members 115 extending parallel in a direction (Y direction) parallel to the plurality of second strip members 103. The plurality of fifth strip members 115 are arranged on the plurality of fourth strip members 113 (Z direction). Each end of the plurality of fifth strip members 115 also does not extend outside the device tray 101 beyond the corresponding fourth strip member. Further, the device tray 101 may further include a plurality of sixth strip members 116 extending parallel in a direction (X direction) parallel to the plurality of fourth strip members 113. The plurality of sixth strip members 116 are arranged on the plurality of fifth strip members 115 (Z direction). Each end 117 of the plurality of sixth strip members 116 also does not extend outside the device tray 101 beyond the corresponding fifth strip member.

[0016] At least one of the plurality of first strip members 102, the plurality of second strip members 103, the plurality of third strip members 111, the plurality of fourth strip members 113, the plurality of fifth strip members 115, and the plurality of sixth strip members 116 may be configured to have a heat capacity that enables heating of the device 105 housed in the housing portion 104 of the device tray 101, and may also be manufactured from a material suitable for heating the device 105. For example, in the case of a resin, epoxy resin, acrylic resin, polyimide resin, polyetherimide resin, polyethersulfone resin, liquid crystal polymer, fluorine-based copolymer resin, etc. may be mentioned. Also, in the case of a metal, iron, nickel, copper, titanium, tungsten, aluminum, platinum, silver, or an alloy thereof (for example, iron-chromium-nickel alloy, etc.), etc. may be mentioned. Further, from the viewpoint of making the heat resistance of the device tray 101 excellent, at least one of the plurality of first strip members 102, the plurality of second strip members 103, the plurality of third strip members 111, the plurality of fourth strip members 113, the plurality of fifth strip members 115, and the plurality of sixth strip members 116 may be manufactured from ceramics. The ceramics may contain at least one of alumina, silicon carbide, silicon nitride, zirconia, mullite, zircon, cordierite, aluminum titanate, magnesium titanate, magnesia, titanium diboride, boron nitride, boron carbide, etc. In particular, the ceramics may contain alumina, mullite, cordierite, zirconia, or silicon carbide. Also, when the device tray 101 is rapidly heated and cooled, the ceramics may contain silicon carbide, and in this case, the surface may be coated with zirconia, yttria, etc. having low reactivity. The plurality of first strip members 102, the plurality of second strip members 103, the plurality of third strip members 111, the plurality of fourth strip members 113, the plurality of fifth strip members 115, and the plurality of sixth strip members 116 may be manufactured from the same material, or may be manufactured from different materials.

[0017] The device tray 101 may further include a wall portion 110 disposed along the outer periphery of the device tray 101 so as to surround the device tray 101 when viewed from above the device tray 101, from the viewpoint of preventing chipping at the end and / or improving handling performance in the conveying operation as needed. The wall portion 110 may be formed like a frame-shaped wall surface on the outer periphery of the device tray 101. The wall portion 110 may be manufactured from at least one of the plurality of first strip members 102, the plurality of second strip members 103, the plurality of third strip members 111, the plurality of fourth strip members 113, the plurality of fifth strip members 115, and the plurality of sixth strip members 116, or may be manufactured from a different material such as a tape. Thus, by disposing the wall portion 110 along the outer periphery of the device tray 101, the strength of the device tray 101 can be increased.

[0018] Next, an example of a method for manufacturing the device tray 101 will be described. This method includes a step of arranging a plurality of third strip members 111 extending parallel to one direction (Y direction). The plurality of third strip members 111 are the strip members arranged at the bottommost in the device tray 101. Each of the plurality of third strip members 111 preferably has a diameter of 1.0 mm to 1.5 mm in a cross-section perpendicular to the extending direction, but depending on the device 105 accommodated in the accommodating portion 104 of the device tray 101, the diameter may be larger or smaller than this. Note that this cross-section is substantially circular in FIG. 2, but may have a shape such as a substantially ellipse or a substantially polygon. Each of the plurality of third strip members 111 may be gel-like for easy arrangement. In this case, when each third strip member 111 is arranged, the bottom 112 of each third strip member 111 becomes flat due to its weight. This method includes a step of arranging a plurality of first strip members 102 on the plurality of third strip members 111. The plurality of first strip members 102 extend parallel to the direction (X direction) intersecting the plurality of third strip members 111. This method includes a step of arranging a plurality of second strip members 103 on the plurality of first strip members 102. The plurality of second strip members 103 extend parallel to the direction (Y direction) intersecting the plurality of first strip members 102. This method may include, if necessary, a step of arranging a plurality of fourth strip members 113 on the plurality of second strip members 103, a step of arranging a plurality of fifth strip members 115 on the plurality of fourth strip members 113, and a step of arranging a plurality of sixth strip members 116 on the plurality of fifth strip members 115. Each of the plurality of first strip members 102, the plurality of second strip members 103, the plurality of fourth strip members 113, the plurality of fifth strip members 115, and the plurality of sixth strip members 116 may also have a diameter of 1.0 mm to 1.5 mm in a cross-section perpendicular to the extending direction, but may have a diameter different from that of each of the plurality of third strip members 111, and may also be gel-like. Note that these cross-sections are substantially circular in FIG. 2, but may have a shape such as a substantially ellipse or a substantially polygon.This method includes the step of heating a plurality of third strip members 111, a plurality of first strip members 102, a plurality of second strip members 103, a plurality of fourth strip members 113, a plurality of fifth strip members 115, and a plurality of sixth strip members 116 so that they sinter with each other.

[0019] This method includes the step of removing the extended portion when the end 106 of each of the plurality of first strip members 102 extends outside the device tray 101 beyond the corresponding second strip member. For the extended portion, for example, by performing cutting, polishing, etc., the extended portion can be removed so that the end 106 of each of the plurality of first strip members 102 does not extend outside the device tray 101 beyond the corresponding second strip member. This method includes the step of cutting the extended portion when the end of each of the plurality of second strip members 103 extends outside the device tray 101 beyond the corresponding first strip member. Similarly, this method includes the step of removing the extended portions of the plurality of third strip members 111, the plurality of fourth strip members 113, the plurality of fifth strip members 115, and the plurality of sixth strip members 116.

[0020] Next, an example of a method for manufacturing the device 105 will be described. This method includes the step of preparing the device tray 101. This method includes the step of accommodating the device 105 in at least one of the plurality of accommodating portions 104 of the device tray 101. Examples of the device 105 include, but are not limited to, electronic devices such as ceramic capacitors, resistors, inductors, filters, etc., semiconductor chips, printed wiring boards, module substrates, medical devices such as DNA chips, small battery devices, etc.

[0021] This method includes the step of heating device tray 101 in which device 105 is accommodated in order to heat device 105. For example, when device 105 is a ceramic electronic device, the ceramic electronic device forms an internal electrode layer and / or laminates a plurality of dielectric sheets serving as insulating layers, presses them, cuts them into chip sizes, and bakes the cut pieces in a firing furnace to form hard ceramic chips. External electrode paste is applied to both sides of the chips and baked, and further plating or the like is applied as necessary for manufacturing. Device tray 101 may be used to accommodate the pieces cut into chip sizes as device 105 in accommodation portion 104 and bake them in a firing furnace. Also, device tray 101 may be used to accommodate ceramic chips as device 105 in accommodation portion 104 and bake the external electrode paste. For example, when device 105 is a semiconductor chip, bonding terminals are formed by heating a semiconductor chip on which precursors of bonding bodies such as solder paste and solder bumps are formed on a plurality of mounting terminals in a reflow furnace. Device tray 101 may be used to accommodate the semiconductor chip on which solder has been deposited as device 105 in accommodation portion 104 and melt the solder in a reflow furnace to round it and form solder bumps. For example, when device 105 is a module substrate, surface mounting of chip components onto the module substrate is performed by applying paste-like solder to necessary locations on the module substrate, placing the chip components at predetermined positions on the module substrate, and heating the module substrate in a reflow furnace to melt the solder and solder the chip components to the module substrate. Device tray 101 may be used to accommodate the module substrate on which solder has been applied and the chip components have been placed as device 105 in accommodation portion 104 and melt the solder to fix the chip components to the substrate.

[0022] Although the above description has been made for specific embodiments, it is obvious to those skilled in the art that the present invention is not limited thereto and various changes and modifications can be made within the scope of the principles of the present invention and the scope of the appended claims.
