Description

本発明は、複数個の配線基板またはパッケージを同時に製造するための多数個取り用配線基板に関する。尚、本発明においては、配線基板には、チップ状電子部品などを搭載し且つ密封するための所謂パッケージも含まれる。   The present invention relates to a multi-piece wiring board for simultaneously manufacturing a plurality of wiring boards or packages. In the present invention, the wiring board includes a so-called package for mounting and sealing a chip-like electronic component or the like.

複数個の配線基板やパッケージを同時に製造するため、平面方向に沿って多数の製品となる配線基板またはパッケージを併設して形成する大版の多数個取り用配線基板が用いられている。かかる大版の多数個取り用配線基板は、製品となる配線基板が平面方向に沿って併設される配線基板集合領域と、その周囲を囲む耳部と、を備えている。耳部や隣接する複数の配線基板集合領域同士間の境界には、ガイド孔が設けられている
耳部や配線基板集合領域同士間の境界に設けたガイド孔は、例えば、大版である複数のグリーンシートを積層する際に、プレス装置側のガイドピンを受け入れて、上層および下層の各グリーンシートの位置合わせに活用される。
In order to manufacture a plurality of wiring boards and packages at the same time, large-size multi-piece wiring boards that are formed together with wiring boards or packages that become a large number of products along the planar direction are used. Such a large-sized multi-piece wiring board includes a wiring board assembly region where wiring boards to be products are provided along the plane direction, and an ear portion surrounding the wiring board collecting area. Guide holes are provided at the boundaries between the ears and a plurality of adjacent wiring board assembly regions. The guide holes provided at the boundaries between the ears and the wiring substrate assembly regions are, for example, large plates. When the green sheets are stacked, the guide pins on the press device side are received and used for alignment of the upper and lower green sheets.

例えば、配線基板が平面方向に沿って併設される大版部位(配線基板集合領域)を、グリーンシートに複数個形成し、隣接する大版部位同士の境界に沿って、複数のガイド孔を形成し、かかるガイド孔を活用して、2回打ち抜きによる変形をなくし、積層精度の向上を図った配線基板の製造方法が提案されている(例えば、特許文献1参照)。
ところで、個々の配線基板やパッケージのサイズは、これらの高性能化および小型化のニーズによって、近年小さくなる傾向にある。また、配線基板やパッケージの取り数の増加によるコスト低減のため、多数個取り用配線基板自体のサイズは、大きくなる傾向にある。このため、上下に複数のグリーンシートを積層する場合、前記耳部や配線基板集合領域同士間の境界に設けたガイド孔を用いて位置合わせする方法では、個々の配線基板などにおける積層ズレによる不具合を解消することは、もはや限界に近付きつつある。
For example, a plurality of large plate parts (wiring board assembly regions) where wiring boards are provided along the plane direction are formed in a green sheet, and a plurality of guide holes are formed along the boundary between adjacent large plate parts. In addition, a method of manufacturing a wiring board has been proposed in which such guide holes are utilized to eliminate deformation caused by punching twice and improve the lamination accuracy (see, for example, Patent Document 1).
By the way, the sizes of individual wiring boards and packages tend to be reduced in recent years due to the need for higher performance and smaller size. In addition, in order to reduce costs due to an increase in the number of wiring boards and packages, the size of the multi-piece wiring board itself tends to increase. For this reason, when laminating a plurality of green sheets on the upper and lower sides, the method of aligning using the guide holes provided at the boundary between the ears and the wiring board assembly areas causes a problem due to laminating misalignment in individual wiring boards. Eliminating is no longer near the limit.

以下において、本発明を実施するための最良の形態について説明する。
図1は、本発明における一形態の多数個取り用配線基板1を示す平面図、図2は、図1中のX−X線の矢視に沿った断面図、図3は、図2中の一点鎖線部分Yの拡大図である。
多数個取り用配線基板1は、図1乃至図3に示すように、製品単位であるパッケージ(配線基板)pが平面(縦・横)方向に沿って複数個併設される配線基板集合領域2と、かかる集合領域2内に位置するパッケージpを貫通する複数のガイド孔Hと、上記配線基板集合領域2の周囲を囲む耳部3と、を備えている。
In the following, the best mode for carrying out the present invention will be described.
FIG. 1 is a plan view showing a multi-piece wiring board 1 according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along the line XX in FIG. 1, and FIG. It is an enlarged view of the alternate long and short dash line portion Y.
As shown in FIGS. 1 to 3, the multi-cavity wiring board 1 includes a wiring board assembly region 2 in which a plurality of packages (wiring boards) p, which are product units, are provided along a plane (vertical / horizontal) direction. And a plurality of guide holes H penetrating through the package p located in the collective region 2 and an ear portion 3 surrounding the periphery of the wiring board collective region 2.

前記配線基板集合領域2と耳部3とは、3層のセラミック(絶縁層)層s1〜s3を一体に積層したものである。このうち、セラミック層s1は、配線基板集合領域2内に位置する複数のパッケージpに共通する底面となる絶縁層であり、且つ平面視が矩形枠形の耳部3も併せて形成する。また、セラミック層s2,s3は、セラミック層s1の上に配置され且つ複数のパッケージpの側壁4,5となる平面視が格子枠状の絶縁層であり、且つ耳部3も有する。このうち、隣接するパッケージp,p間に位置する側壁5は、配線基板集合領域2の外周に沿って位置する側壁4の二倍の厚みを有する。即ち、側壁5は、図1,図2中の破線で示す切断予定線6を挟んで、一対の側壁4を合わせた厚みを有する。尚、セラミック層s1〜s3は、例えばアルミナ系などのセラミックからなるほか、低温焼成セラミックの1種であるガラス−セラミックからなるものとしても良い。
配線基板集合領域2は、図1に示すように、縦・横に9個ずつ合計81個のパッケージpを平面方向に沿って併設しており、平面視が正方形を呈する。
The wiring board assembly region 2 and the ear portion 3 are obtained by integrally stacking three ceramic (insulating layer) layers s1 to s3. Among these, the ceramic layer s1 is an insulating layer serving as a bottom surface common to the plurality of packages p located in the wiring board assembly region 2, and also forms an ear portion 3 having a rectangular frame shape in plan view. The ceramic layers s2 and s3 are insulating layers having a lattice frame shape in plan view, which are disposed on the ceramic layer s1 and become the side walls 4 and 5 of the plurality of packages p, and also have ears 3. Among these, the side wall 5 located between the adjacent packages p, p has a thickness twice that of the side wall 4 located along the outer periphery of the wiring board assembly region 2. That is, the side wall 5 has a combined thickness of the pair of side walls 4 with a planned cutting line 6 indicated by a broken line in FIGS. The ceramic layers s1 to s3 may be made of, for example, ceramic such as alumina, or may be made of glass-ceramic that is one kind of low-temperature fired ceramic.
As shown in FIG. 1, the wiring board assembly region 2 has a total of 81 packages p in the vertical and horizontal directions along the plane direction, and has a square shape in plan view.

図1乃至図3に示すように、追って切断予定線6に沿って切断されることで、1つの製品となるパッケージpは、平面視が矩形の底面7aと、これらの四辺から立設する側壁4とからなるキャビティ7を備え、例えば、約1×1×1mmの立方体を呈する。かかるパッケージpは、キャビティ7内に図示しないチップ状電子部品(例えば、水晶振動子やSAWフィルタ)を搭載して密封する。
図1,図2に示すように、縦・横合計81個のパッケージpのうち、配線基板集合領域2の中心に位置する1つのパッケージpと、この中心に対して対称で且つ等間隔な位置の4つパッケージpとの位置に、当該多数個取り用配線基板1の表面8と裏面9との間を貫通する5つのガイド孔Hが形成されている。
As shown in FIGS. 1 to 3, the package p that is to be one product by being cut along the planned cutting line 6 later has a rectangular bottom surface 7 a in plan view and side walls that stand from these four sides. 4 and has a cube of about 1 × 1 × 1 mm, for example. The package p is sealed by mounting a chip-shaped electronic component (for example, a crystal resonator or a SAW filter) (not shown) in the cavity 7.
As shown in FIG. 1 and FIG. 2, one package p located at the center of the wiring board assembly region 2 out of a total of 81 packages p in the vertical and horizontal directions, and symmetrical and equidistant positions with respect to this center The five guide holes H penetrating between the front surface 8 and the rear surface 9 of the multi-cavity wiring board 1 are formed at the positions of the four packages p.

前記ガイド孔Hは、各パッケージpのキャビティ7および四辺の側壁5の内側部分を含む平面視が円形で且つ内径が約1〜5mm程度の垂直な貫通孔であり、前記セラミック層s1〜s3における所定の位置に、予め図示しないポンチとダイスとによる打ち抜き加工により形成されたものである。
尚、ガイド孔Hが貫通するパッケージpは、製品にならないため、切断予定線6に沿って切断した後に廃棄される。このため、ガイド孔Hは、配線基板集合領域2の面積およびそこに併設されるパッケージpの数に応じて、最小数とすることが望ましい。
また、図1,図2に示すように、耳部3には、4つの各辺ごとに一対のガイド孔fが貫通しており、これらは前記ガイド孔Hと離隔した位置に形成されている。尚、ガイド孔fは、図示の便宜上、前記ガイド孔Hとほぼ同じ内径として図示したが、これよりも大径としても良い。
The guide hole H is a vertical through hole including a cavity 7 of each package p and an inner part of the side walls 5 on the four sides, and is a vertical through hole having a circular shape and an inner diameter of about 1 to 5 mm, in the ceramic layers s1 to s3. It is formed in advance at a predetermined position by punching with a punch and a die (not shown).
The package p through which the guide hole H passes does not become a product, and is discarded after being cut along the planned cutting line 6. For this reason, it is desirable that the number of guide holes H be the minimum number according to the area of the wiring board assembly region 2 and the number of packages p provided therewith.
As shown in FIGS. 1 and 2, the ear portion 3 has a pair of guide holes f penetrating every four sides, and these are formed at positions separated from the guide holes H. . The guide hole f is illustrated as having an inner diameter that is substantially the same as the guide hole H for convenience of illustration, but may have a larger diameter.

以上のような多数個取り用配線基板1は、次のようにして形成される。尚、以下では、焼成後に前記セラミック層s1〜s3となる各グリーンシートには、便宜上同じ符号を用い、ガイド孔fは、ガイド孔Hよりも大径として図示する。
予め、図4の概略図に示すように、ベース板Bの平坦な表面における所定の位置に、所要の直径であるガイドピンPa,Pbを立設させた積層治具Gを用意する。このうち、太径のガイドピンPaの直径は、前記配線基板集合領域2のガイド孔Hの内径とほぼ同じか、もしくは数μmのみ大きく、便宜上大径として図示したガイドピンPbの直径は、前記耳部3のガイド孔fの内径とほぼ同じか、もしくは数μmのみ大きくなるように、事前に設定されている。
The multi-piece wiring board 1 as described above is formed as follows. In the following description, the same reference numerals are used for the green sheets that become the ceramic layers s1 to s3 after firing, and the guide hole f is illustrated as having a larger diameter than the guide hole H.
As shown in the schematic diagram of FIG. 4, a stacking jig G is prepared in which guide pins Pa and Pb having required diameters are erected at predetermined positions on the flat surface of the base plate B in advance. Among these, the diameter of the guide pin Pa having a large diameter is substantially the same as the inner diameter of the guide hole H in the wiring board assembly region 2 or is only several μm larger. It is set in advance so as to be substantially the same as the inner diameter of the guide hole f of the ear portion 3 or to be larger by several μm.

先ず、図4の概略図で示すように、積層治具Gの各ガイドピンPa,Pbに、グリーンシートs1の所定の位置に予め設けた複数の貫通孔h1および複数のガイド孔fを個別に挿入しつつ、かかるグリーンシートs1をベース板Bの平坦な表面上に載置する。
次に、図5の概略図で示すように、積層治具Gの各ガイドピンPaに、複数の貫通孔h2を有し且つ平面視が格子枠状であるグリーンシートs2において、所定の位置に予め設けた複数の貫通孔h2を個別に挿入しつつ、かかるグリーンシートs2を前記グリーンシートs1の上に積層する。
First, as shown in the schematic diagram of FIG. 4, a plurality of through holes h1 and a plurality of guide holes f provided in advance at predetermined positions of the green sheet s1 are individually provided in the guide pins Pa and Pb of the stacking jig G. The green sheet s1 is placed on the flat surface of the base plate B while being inserted.
Next, as shown in the schematic diagram of FIG. 5, each guide pin Pa of the stacking jig G has a plurality of through holes h <b> 2 and has a lattice frame shape in plan view. The green sheet s2 is stacked on the green sheet s1 while inserting a plurality of through holes h2 provided in advance individually.

次いで、図6の概略図で示すように、積層治具Gの各ガイドピンPaに、複数の貫通孔h3を有し且つ平面視が前記と同じ格子枠状であるグリーンシートs3において、所定の位置に予め設けた複数の貫通孔h3を個別に挿入しつつ、かかるグリーンシートs3を前記グリーンシートs1,s2の上に積層する。この間において、グリーンシートs1〜s3の貫通孔1〜h3は、互いに同心で連通するため、これらの間に積層ズレのない円柱形の前記ガイド孔Hを形成する。
尚、グリーンシートs2,s3も、耳部3を有し且つガイド孔fを有している。
Next, as shown in the schematic diagram of FIG. 6, in the green sheet s <b> 3 having a plurality of through holes h <b> 3 in each guide pin Pa of the stacking jig G and having the same lattice frame shape as described above, The green sheets s3 are stacked on the green sheets s1 and s2 while individually inserting a plurality of through holes h3 provided in advance at positions. During this time, since the through holes 1 to h3 of the green sheets s1 to s3 communicate with each other concentrically, the cylindrical guide hole H without stacking deviation is formed therebetween.
The green sheets s2 and s3 also have ears 3 and guide holes f.

更に、最上層のグリーンシートs3の表面および各ガイドピンPaの頂部に、図示しないゴムなどの弾性層を載置した後、図6中の白抜きの矢印で示すように、かかる弾性層の上方から下向きで且つベース板Bの全面に対し、ほぼ均一な圧力を加えて、グリーンシートs1〜s3を圧着し、これらの積層体を形成する。
そして、グリーンシートs1〜s3の積層体を、積層治具Gから取り出し、図示しない焼成炉に挿入し、所定の温度域および時間で焼成する。
この結果、図7に示すように、前記と同じ多数個取り用配線基板1が得られる。
Furthermore, after placing an elastic layer such as rubber (not shown) on the surface of the uppermost green sheet s3 and the top of each guide pin Pa, as shown by the white arrow in FIG. The green sheets s <b> 1 to s <b> 3 are pressure-bonded by applying a substantially uniform pressure to the entire surface of the base plate B from the bottom to form these laminates.
And the laminated body of the green sheets s1-s3 is taken out from the lamination jig | tool G, inserted in the baking furnace which is not shown in figure, and is baked with a predetermined temperature range and time.
As a result, as shown in FIG. 7, the same multi-chip wiring board 1 as described above is obtained.

以上のような多数個取り用配線基板1によれば、外側の耳部3の各辺に設けた複数のガイド孔fに加え、耳部3の内側に位置する配線基板集合領域2における中心とこれから対称で且つ等間隔な位置との各パッケージpを貫通する5つのガイド孔H(h1〜h3)を用いて、前記グリーンシートs1〜s3が積層ズレなく精度良く積層され且つ圧着・焼成されている。このため、図1,図7中の破線で示す切断予定線6に沿って、ダイシング加工などにより、多数個取り用配線基板1を切断し且つ分割することで、形状および寸法精度の高い多数のパッケージpを確実に得ることが可能となる。   According to the multi-cavity wiring board 1 as described above, in addition to the plurality of guide holes f provided on each side of the outer ear part 3, the center in the wiring board assembly region 2 located inside the ear part 3 Using the five guide holes H (h1 to h3) penetrating each package p at symmetric and equally spaced positions, the green sheets s1 to s3 are accurately laminated without being misaligned and pressed and fired. Yes. For this reason, by cutting and dividing the multi-cavity wiring board 1 by dicing or the like along the planned cutting line 6 shown by the broken lines in FIGS. 1 and 7, a large number of shapes and dimensional accuracy are high. The package p can be obtained reliably.

図8,図9は、前記多数個取り用配線基板1の変形形態を示す平面図である。
即ち、図8の平面図で示すように、配線基板集合領域2の中心の周囲に等間隔で4つのガイド孔Hを形成し、これらのガイド孔Hから斜め方向に連続する耳部3の各辺に複数のガイド孔fを形成した多数個取り用配線基板1aとしても良い。
また、図9の平面図で示すように、配線基板集合領域2の中心に1つのガイド孔Hを形成し、かかるガイド孔Hからほぼ同様に離間する耳部3の各辺に複数のガイド孔fを形成した多数個取り用配線基板1bとしても良い。
8 and 9 are plan views showing modifications of the multi-cavity wiring board 1.

前記配線基板集合領域12および耳部13は、4層のセラミック(絶縁層)層s4〜s7を一体に積層したものであり、前記同様のセラミックまたは低温焼成セラミックの1種であるガラス−セラミックからなる。
FIG. 10 is a plan view showing a multi-piece wiring board 10 of a different form, and FIG. 11 is a partially enlarged cross-sectional view taken along the line ZZ in FIG.
As shown in FIGS. 10 and 11, the multi-cavity wiring board 10 includes a wiring board assembly region 12 in which a plurality of wiring boards P as product units are provided along the plane (vertical / horizontal) direction. A plurality of (four) guide holes H penetrating the plurality of wiring boards P located in the collective region 12 and ears 13 surrounding the collective region 12 are provided.
The wiring board assembly region 12 and the ear portion 13 are formed by integrally laminating four ceramic (insulating layer) layers s4 to s7, and are made of glass-ceramic which is one of the same ceramics or low-temperature fired ceramics. Become.

図10,図11に示すように、前記集合領域12と耳部13との境界、および上記集合領域12内に位置する複数の配線基板P同士の境界に沿って、断面ほぼV字形の切断予定溝dが、平面視で格子形状に形成されている。
前記配線基板集合領域12は、図10に示すように、縦・横に9個ずつ合計81個の配線基板Pを平面方向に沿って併設しており、平面視が正方形を呈する。
図11に示すように、破線の切断予定溝dに沿って切断されることで、1つの製品となる配線基板Pは、セラミック層s4〜s7と、これらの間や表面および裏面に形成されるWなどからなる配線層やパッドなどの導体層と、かかる配線層同士や導体層との間を接続するビア導体(何れも図示せず)と、を含んでいる。
As shown in FIG. 10 and FIG. 11, the cutting plan is substantially V-shaped in section along the boundary between the collective region 12 and the ear portion 13 and the border between the plurality of wiring boards P located in the collective region 12. The grooves d are formed in a lattice shape in plan view.
As shown in FIG. 10, the wiring board assembly area 12 has a total of 81 wiring boards P in the vertical and horizontal directions along the plane direction, and has a square shape in plan view.
As shown in FIG. 11, by cutting along a broken cutting scheduled groove d, the wiring board P that is one product is formed between the ceramic layers s <b> 4 to s <b> 7, between these, the front surface, and the back surface. A wiring layer made of W or the like, a conductor layer such as a pad, and via conductors (none of which are shown) connecting the wiring layers or between the conductor layers are included.

尚、図11において、上側のセラミック層s6,s7には、これらを貫通し且つ底面にセラミック層s5の表面が露出する平面視が矩形または円形などのキャビティを形成しても良く、かかるキャビティの底面には、図示しないICチップなどの電子部品や発光ダイオードなどの発光素子が搭載される。
4つのガイド孔Hは、図10に示すように、縦・横合計81の配線基板Pのうち、配線基板集合領域12の中心に対し、互いに対称で且つ等間隔になる位置の各配線基板Pを貫通している。かかるガイド孔Hは、配線基板Pのサイズが平面視で約3×3mmの場合、約1〜2mmの内径とされている。
一方、耳部13のガイド孔fは、各辺ごとに2個ずつ同じ位置に配置されている。尚、ガイド孔fは、図解の便宜上、前記ガイド孔Hの内径とほぼ同じとしたが、これにより大径としても良い。
In FIG. 11, the upper ceramic layers s6 and s7 may be formed with cavities having a rectangular shape or a circular shape in a plan view in which the surface of the ceramic layer s5 is exposed on the bottom surface. On the bottom surface, electronic components such as an IC chip (not shown) and light emitting elements such as light emitting diodes are mounted.
As shown in FIG. 10, the four guide holes H are formed in the wiring boards P at a position that is symmetrical and equidistant from each other with respect to the center of the wiring board assembly region 12 out of the total 81 vertical and horizontal wiring boards P. It penetrates. The guide hole H has an inner diameter of about 1 to 2 mm when the size of the wiring board P is about 3 × 3 mm in plan view.
On the other hand, two guide holes f of the ear portion 13 are arranged at the same position for each side. Note that the guide hole f is substantially the same as the inner diameter of the guide hole H for convenience of illustration, but it may have a larger diameter.

以上のような多数個取り用配線基板10も、前記同様の方法により製造される。即ち、追ってセラミック層s4〜s7なる各グリーンシートごとの所定の位置に、予め前記ガイド孔Hおよびガイド孔fと同じ内径の貫通孔を打ち抜き加工で形成しておき、前記積層治具Gのガイドピン9a,9bに各貫通孔を挿通させつつ、順次積層し且つ圧着した後、焼成することで、積層ズレがないか、従来よりも少なくした多数個取り用配線基板10を得ることができる。
以上のような多数個取り用配線基板10によれば、セラミック層s4〜s7が積層ズレなく精度良く積層され且つ圧着・焼成されている。このため、図10,図11中の切断予定溝dに沿って、ダイシング加工などにより、多数個取り用配線基板10を切断し且つ分割することで、形状および寸法精度の高い多数の配線基板Pを確実に得ることが可能となる。
The multi-piece wiring board 10 as described above is also manufactured by the same method as described above. That is, a through hole having the same inner diameter as the guide hole H and the guide hole f is formed in advance at a predetermined position for each green sheet of the ceramic layers s4 to s7, and the guide of the stacking jig G is formed. By sequentially laminating and pressing the pins 9a and 9b through the through-holes and firing, the multi-wiring substrate 10 having no misalignment or less than the conventional one can be obtained.
According to the multi-piece wiring substrate 10 as described above, the ceramic layers s4 to s7 are accurately laminated without being misaligned, and are pressed and fired. For this reason, a large number of wiring boards P with high shape and dimensional accuracy can be obtained by cutting and dividing the multi-piece wiring board 10 by dicing or the like along the planned cutting groove d in FIGS. Can be obtained reliably.

尚、多数個取り用配線基板10の配線基板集合領域12内に設けるガイド孔Hは、前記図9と同様に、上記集合領域12の中心に位置する配線基板Pを貫通する1つのみとしたり、前記図1と同様に、上記集合領域12の中心とその周囲に等間隔の各配線基板Pを貫通する5つの形態としても良い。これらの形態では、耳部13のガイド孔fも、ガイド孔Hの数や位置に応じて、これらとほぼ等間隔で互いに離間した位置に形成される。   In addition, the guide hole H provided in the wiring board assembly region 12 of the multi-piece wiring substrate 10 is only one that penetrates the wiring substrate P located at the center of the assembly region 12 as in FIG. As in FIG. 1, five forms may be used in which the wiring substrate P is penetrated at equal intervals around the center of the gathering region 12 and its periphery. In these forms, the guide holes f of the ear portion 13 are also formed at positions spaced apart from each other at substantially equal intervals according to the number and position of the guide holes H.

本発明は、以上において説明した各実施の形態に限定されるものではない。
前記ガイド孔Hや耳部3,13のガイド孔fは、平面視が円形に限らず、平面視がほぼ正方形や長方形や、あるいは、平面視が長円形や楕円形である形態としても良い。これらの場合、前記積層治具のガイドピンの断面も同じ形状とされると共に、積層すべきグリーンシートの向きの是非も確認することが可能となる。
また、前記イド孔Hは、配線基板集合領域において、その中心に対し、互いに対称で且つ等間隔となる位置に、2つ、3つ、あるいは5つ以上を設けても良い。
更に、前記イド孔Hは、複数のグリーンシートを積層する際の位置合わせだけではなく、各グリーンシートの次工程への移送時における位置決めにも適用でき、あるいは、焼成後の検査においてレーザ光線などを貫通させる検査工程にも活用することが可能である。
The present invention is not limited to the embodiments described above.
The guide hole H and the guide holes f of the ear portions 3 and 13 are not limited to a circular shape in plan view, and may be in a form of a substantially square or rectangular shape in plan view, or an oval shape or an oval shape in plan view. In these cases, the cross-section of the guide pins of the stacking jig is also the same shape, and it is possible to check the right or wrong direction of the green sheets to be stacked.
Further, two, three, or five or more id holes H may be provided at positions that are symmetrical to each other and equally spaced with respect to the center in the wiring board assembly region.
Furthermore, the id hole H can be applied not only to alignment when laminating a plurality of green sheets, but also to positioning when transferring each green sheet to the next process, or a laser beam or the like in inspection after firing. It is also possible to utilize it for the inspection process that penetrates through.

また、本発明の多数個取り用配線基板は、複数の配線基板集合領域が耳部を介して隣接する大版の形態にも適用することができる。かかる形態では、複数の配線基板集合領域ごとに、これらを貫通するガイド孔Hの数や位置を替えても良い。
加えて、前記配線基板集合領域を貫通するガイド孔Hは、各パッケージや配線基板が平面視の各辺で1mm未満と微少サイズの場合には、隣接する2個または4個のパッケージや配線基板にまたがって貫通する形態としても良い。
Further, the multi-cavity wiring board of the present invention can be applied to a large-sized form in which a plurality of wiring board assembly regions are adjacent to each other through the ears. In such a form, the number and position of the guide holes H penetrating through the plurality of wiring board assembly regions may be changed.
In addition, the guide holes H penetrating the wiring board assembly region are adjacent to two or four packages or wiring boards when each package or wiring board has a very small size of less than 1 mm on each side in plan view. It is good also as a form which penetrates over.
