Abstract
Description
- The present invention relates to a belt-like electronic component package tape containing electronic components used primarily for automated mounting on wiring boards and the like of a variety of electronic apparatuses. The invention also relates to a method of manufacturing the same.
- In recent years, automated mounting of electronic components on wiring boards has made considerable progress in manufacture of various electronic apparatuses, and there is a continuous rise that such electronic components as switches, variable resistors and the like devices are packed and delivered in the form of package tapes, in which the electronic components are stored individually in large number of storage pockets in an embossed tape configuration.
- Description is now provided of one such electronic component package tape of the prior art with reference to
FIG. 4 andFIG. 5 . -
FIG. 4 is a sectional view of an ordinary electronic component package tape. InFIG. 4 ,carrier tape 301 made of an insulation film in a belt-like form has a plurality ofstorage pockets 311 of generally a concaved box shape formed in a consecutive manner at predetermined pitches.Electronic components 302 such as switches and variable resistors are stored individually in thesestorage pockets 311 in the same orientation. -
Cover tape 303 of a ribbon-like form made of an insulation film is bonded to an upper surface ofcarrier tape 301 to seal the openings ofstorage pockets 311. The electronic component package tape is thus constructed. - The electronic component package tape of this kind is wound into a roll on a reel for transportation (not shown), and packed for storage and the subsequent shipment. The transportation reel is loaded on an automatic mounting machine (not shown) when
electronic components 302 are mounted on wiring boards and the like (not shown) of the electronic apparatuses. - The belt-like electronic component package tape is pulled out of the transportation reel by the automatic mounting machine, and after
cover tape 303 is peeled off upward, a suction head (not shown) of the automatic mounting machine holds and picks upelectronic components 302 one after another fromstorage pockets 311 ofcarrier tape 301, and places them in predetermined positions on the wiring boards.Electronic components 302 are hence mounted on the wiring boards by reflow soldering or the like method. - There occasionally occurs a problem during the automated mounting operation that
electronic component 302 sticks to the underside ofcover tape 303 and comes out of thecarrier tape 301 whencover tape 303 is peeled offcarrier tape 301, if a surface ofelectronic component 302 is stained with oil or the like substance. - For this reason,
cover tape 303 is so formed that the underside surface is provided with a plurality ofprotrusions 332, each havinghole 331 in the center, as shown in the sectional view ofFIG. 5 , in order thatelectronic components 302 can come into close proximity ofprotrusions 332 having less surface areas to contact instead of the entire surface ofcover tape 303. The electronic component package tape devised and formed in this manner preventselectronic components 302 from sticking onto the underside surface ofcover tape 303 even whenelectronic components 302 are stained with oil and the like substances, thereby avoiding problems in the automated mounting operation. - One example of the prior art publications known to be relevant to the invention of this application is Japanese Patent Unexamined Publication, No. H04-31215.
- In the electronic component package tape of the prior art, as illustrated above, it is likely that the automated mounting operation is interfered due to sticking of
electronic components 302 whencover tape 303 used has a flat surface as shown inFIG. 4 . On the other hand, whencover tape 303 is provided withprotrusions 332 havingholes 331 as shown inFIG. 5 to prevent this problem, there gives rise to another problem thatholes 331 inprotrusions 332 allow dust and the like particles to get intostorage pockets 311 during transportation, and the dust enters insideelectronic components 302 such as switches and variable resistors, possibly resulting in malfunctioning ofelectronic components 302. - An electronic component package tape of the present invention comprises a carrier tape of belt-like form storing electronic components in a plurality of storage pockets formed into a concaved box shape at predetermined pitches, a cover tape of ribbon-like form bonded to the carrier tape to seal upper openings of the storage pockets, and first protrusions, each having a tip of rounded surface, formed on an underside surface of the cover tape facing the electronic components.
- This structure, provided with the protrusions of rounded surface and no hole, prevents dust and the like particles from getting into the storage pockets, and the electronic components from sticking to the underside surface of the cover tape due to oil and the like substances, thereby achieving the electronic component package tape capable of ensuring reliable operation of the automated mounting.
- Furthermore, a method of manufacturing electronic component package tapes of the present invention comprises a step of holding a ribbon-like cover tape between a first rotating body having a plurality of convex portions formed at predetermined pitches around the periphery thereof and a second rotating body having concave portions formed around the periphery thereof in a corresponding manner to the convex portions, a step of forming protrusions of rounded surface on the cover tape by rotating the first rotating body and the second rotating body, and a step of bonding the cover tape formed with the protrusions to an upper surface of the belt-like carrier tape in a manner to cover openings of storage pockets formed in the carrier tape for carrying electronic components.

FIG. 1 toFIG. 3 .FIG. 1 is a sectional view of an electronic component package tape according to the exemplary embodiment of this invention,FIG. 2 is a plan view of the electronic component package tape shown inFIG. 1 , andFIG. 3 is a schematic drawing illustrating the steps of manufacturing the electronic component package tape shown inFIG. 1 . - According to this exemplary embodiment of the invention in
FIG. 1 , the electronic component package tape comprises belt-like carrier tape 11 carryingelectronic components 2 in a plurality ofstorage pockets 11A formed into a concaved box-like shape at predetermined pitches, ribbon-like cover tape 12 bonded tocarrier tape 11 to seal upper openings ofstorage pockets 11A, andfirst protrusions 12B having rounded tips formed on an underside surface ofcover tape 12 facingelectronic components 2. - In addition,
second protrusions 11B may be formed on a bottom surfaces ofstorage pockets 11A in a manner to protrude upward. - Description is provided in more detail of the structure of the electronic component package tape according to this exemplary embodiment of the invention.
-
Carrier tape 11 is a belt-like form made of an insulation film such as polystyrene and the like materials. Thiscarrier tape 11 is provided with a plurality ofstorage pockets 11A of generally a concaved box-like shape formed in a consecutive manner at predetermined pitches in a longitudinal direction thereof. - Formed on bottom surfaces of
storage pockets 11A are a plurality ofprotrusions 11B (i.e., second protrusions) protruding upward and arecess 11C in the center bottom surface of each ofstorage pockets 11A.Carrier tape 11 also has sprocketholes 11D formed at predetermined pitches along one side orthogonal to a widthwise direction thereof. - These
storage pockets 11A individually containelectronic components 2 such as switches and variable resistors having terminals and control knobs extending sideway in the same orientation. -
Cover tape 12 is a ribbon-like form made of an insulation film such as polyethylene terephthalate and the like materials. Thiscover tape 12 is provided with adhesive layers of a thermo-compression type alongsealing areas 12A at both sides of its lower surface, whichbond cover tape 12 to an upper surface ofcarrier tape 11 in a manner to seal the upper openings ofstorage pockets 11A. - Furthermore, there are a plurality of
protrusions 12B (i.e., first protrusions), each having a tip of generally a rounded surface formed on the underside surface ofcover tape 12 facingelectronic components 2 in a protruding manner with a small space to upper surfaces ofelectronic components 2. The electronic component package tape is constructed as above. - In other words, the electronic component package tape of the present invention is not provided with any hole in
protrusions 12B formed to protrude on the underside surface ofcover tape 12, and thiscover tape 12 prevents dust and the like particles from getting intostorage pockets 11A containingelectronic components 2 since it is bonded tocarrier tape 11 alongsealing areas 12A at both sides of and covers the upper openings ofstorage pockets 11A. - In addition,
carrier tape 11 is provided withprotrusions 11B formed upward on the bottom surfaces ofstorage pockets 11A. Sinceprotrusions 11B makeelectronic components 2 not liable to stick to the surface ofcarrier tape 11, they help makeelectronic components 2 easily removable fromstorage pockets 11A during automated mounting, thereby achieving the automated mounting operation more reliable. - Description is provided next of a method of manufacturing the electronic component package tape of the structure discussed above with reference to
FIG. 3 . In order to help make structures of the individual elements more comprehensible,FIG. 3 illustrates certain elements with a different scale of magnification. - In
FIG. 3 , first rotatingbody 13 is provided withconvex portions 13A at predetermined pitches around its periphery. Second rotatingbody 14 hasconcave portions 14A formed around its periphery in locations corresponding to convexportions 13A. First rotatingbody 13 and second rotatingbody 14 are so arranged as to face each other withconvex portions 13A in engagement toconcave portion 14A around their peripheries, and that both rotating bodies are rotatable in a synchronized motion. - A ribbon-like tape material supplied from the left side of the drawing passes through the peripheries of first rotating
body 13 and second rotatingbody 14 as they rotate, while being held betweenconvex portions 13A andconcave portions 14A. Hence produced is ribbon-like cover tape 12 formed withprotrusions 12B having the tips of generally the rounded surface at the predetermined pitches. - In this case,
cover tape 12 has a thickness not smaller than 50 μm but not greater than 70 μm, andprotrusions 12B of the rounded surfaces are formed into a height not smaller than 0.1 mm but not larger than 0.3 mm at such pitches so that at least twoprotrusions 12B confront an upper surface of each of the electronic components. - In this embodiment here,
protrusions 12B are not likely to maintain their protruding shape because they tend to get flattened if the height is smaller than 0.1 mm, orprotrusions 12B become liable to break and covertape 12 tend to get wrinkled if the height exceeds 0.3 mm. - In other words, it is desirable to form
protrusions 12B of such a height that a ratio of the height to the thickness ofcover tape 12 generally becomes not smaller than 1.5 but not larger than 6, and more preferably in a ratio between 2 and 4. - As an alternative way of forming
such protrusions 12B oncover tape 12, there is another method, in which the tape material is supplied by a feeding device to make it pass through intermittently between a vertically reciprocating punch and a base plate with a bored hole corresponding to the punch. When compared with this method, however, the method discussed above for formingprotrusions 12B by passing the tape material between first and secondrotating bodies protrusions 12B easily and continuously at a faster rate. -
Cover tape 12 havingprotrusions 12B formed in this manner is guided downward, and placed on top ofcarrier tape 11 supplied from the right side of the drawing in a manner that the tips ofprotrusions 12B confront smallelectronic components 2 such as detector switches stored in a predetermined orientation insidestorage pockets 11A. - Following the above, overlapped
cover tape 12 andcarrier tape 11 pass throughsealing device 15 equipped with a heater (not shown), a press punch (not shown) and the like, wherebysealing areas 12A on the underside surface ofcover tape 12 are heated and pressed, to complete the electronic component package tape consisting ofcover tape 12 bonded to the upper surface ofcarrier tape 11 containingelectronic components 2 in itsstorage pockets 11A. - Electronic component package tape of this type is wound into a roll on a reel for transportation (not shown), and packed for storage and the subsequent shipment. The transportation reel is loaded on an automatic mounting machine (not shown) when
electronic components 2 are mounted on wiring boards and the like (not shown) of electronic apparatuses. - The belt-like electronic component package tape is pulled out of the transportation reel by the automatic mounting machine, and after
cover tape 12 is peeled off upward, a suction head (not shown) of the automatic mounting machine holds and picks upelectronic components 2 one after another fromstorage pockets 11A ofcarrier tape 11, and places them in predetermined positions on the wiring boards.Electronic components 2 are then mounted on the wiring boards by means of reflow soldering or the like method. - Since
protrusions 12B of generally the rounded surface ofcover tape 12 confronting upper surfaces ofelectronic components 2 result in reduction of an area of contact betweenprotrusions 12B and the upper surfaces ofelectronic components 2, this embodiment can preventelectronic components 2 from sticking to covertape 12 whencover tape 12 is being peeled off fromcarrier tape 11 even ifelectronic components 2 are stained by any chance with oil or the like substance, thereby ensuring reliability of the automated mounting to wiring boards. - Moreover, since the underside surfaces of
electronic components 2 are in contact withprotrusions 11B on the bottom surfaces ofstorage pockets 11A, which also results in reduction of an area of contact between them, this structure can preventelectronic components 2 from sticking to the bottom surfaces ofstorage pockets 11A, and help makeelectronic components 2 easily removable fromstorage pockets 11A. - According to the present exemplary embodiment, as described,
protrusions 12B having the tips of generally the rounded surface are formed without hole on the underside surface ofcover tape 12 facingelectronic components 2.Protrusions 12B can therefore prevent dust and the like particles from getting intostorage pockets 11A, and avoid the electronic components from sticking to the underside surface ofcover tape 12 due to oil and the like substances, thereby achieving the electronic component package tape capable of ensuring reliable operation of the automated mounting. -
Electronic components 2 such as switches and variable resistors are provided with moving members like control knobs and the like as compared with passive components such as semiconductors and capacitors. It is therefore especially important to keep such mechanical components free from dust during transportation and storage because of the possibility that intended operation of the moving members is impaired if dust entered intostorage pockets 11A reaches inside of the switches and the like. - The presence of
protrusions 11B formed to project upward from the bottom surfaces ofstorage pockets 11A ofcarrier tape 11 reduces the areas of contact where the underside surfaces ofelectronic components 2 rest upon theseprotrusions 11B, and preventselectronic components 2 from sticking tocarrier tape 11. This helps ease the removal ofelectronic components 2 fromstorage pockets 11A in the automated mounting, and ensures reliable operation of the automated mounting. - In addition, formation of
recesses 11C in generally the center of the individual bottom surfaces ofstorage pockets 11A also reduces the area of contact with the underside surfaces ofelectronic components 2 even ifprotrusions 11B become deformed or flattened. - The presence of
recesses 11C is also effective for reduction of the areas of contact between the bottom surfaces ofstorage pockets 11A and the underside surfaces ofelectronic components 2 whenprotrusions 11B are not provided. Accordingly, recesses 11C makeelectronic components 2 not liable to stick tocarrier tape 11, help ease the removal ofelectronic components 2 fromstorage pockets 11A in the automated mounting, and thereby they ensure reliable operation of the automated mounting. - The electronic component package tape can be produced by a simple method, in which ribbon-
like cover tape 12 is placed between firstrotating body 13 having the plurality ofconvex portions 13A formed at predetermined pitches around the periphery thereof and secondrotating body 14 havingconcave portions 14A formed around the periphery thereof in locations corresponding toconvex portions 13A, and first and secondrotating bodies protrusions 12B of generally rounded surface oncover tape 12. - The electronic component package tape and the method of manufacturing the same according to the present invention have an advantageous feature of providing the product that is not likely to allow dust to get into the storage pockets, and useful for the electronic components and the like adapted primarily for automated mounting on wiring boards and the like for use in a variety of electronic apparatuses.
