Abstract

(57)【要約】 運転熱を導出する必要のある出力構造部材(10)が、ろう付け面(12)を介してプリント配線板(13)上に配置されていて、熱を導出するため絶縁区間(19)によって電気的に絶縁されており、またろう付け面(12)の領域の外方には貫通接触部(18)が設けられている。この貫通接触部(18)は、プリント配線板(13)の底部層(23)を介し低熱部(35)に向う良好な熱接触を実現している。絶縁区間(19)は、電位の負荷された出力構造部材(10)の載置面と、多くの場合アース電位の負荷された熱を低熱部(35)の金属載置面との間の電気的な遮断を保証している。従来形式の多層状のプリント配線板(13)(多層体)内に既に存在している中間層(21,22)によって、また場合によっては付加的に錫の充填された貫通接触部(18)によって、出力構造部材(10)から低熱部(35)への熱の導出が付加的に改善されている。 (57) [Summary] The output structural member (10), which needs to derive operating heat, is arranged on the printed wiring board (13) via the brazing surface (12), and is insulated to derive heat. It is electrically insulated by the section (19) and is provided with a penetrating contact (18) outside the area of the brazing surface (12). This through contact part (18) realizes good thermal contact toward the low heat part (35) through the bottom layer (23) of the printed wiring board (13). The insulating section (19) is an electrical connection between the mounting surface of the output structural member (10), which is loaded with a potential, and the heat, often ground potential, between the metal mounting surface of the low heat section (35). Guarantees proper shut down. Through-contacts (18) filled with intermediate layers (21, 22) already present in a conventional multilayer printed wiring board (13) (multilayer body) and optionally additionally tin. This additionally improves the transfer of heat from the output structural member (10) to the low heat section (35).

Description

【発明の詳細な説明】 プリント配線板から成る装置 技術分野 本発明は、請求項1の上位概念に基く、プリント配線板から成る装置に関する 。 背景技術 この種の公知の装置にあっては、1数又は複数の出力構造部材内に発生する熱 を低熱部に導出することが困難である場合が多い。その理由は、プリント配線板 がその両表面の少くとも一方の表面に種々の電位で導かれている多数のプリント 配線回路を有しており、これらは相互に交差していて低熱部と交差することが許 されていないからである。例えばドイツ国特許第3505167号明細書によれ ば、出力構造部材の熱を貫通接触部を介してプリント配線板の下側に導出するこ とが公知である。この貫通接触部は、出力構造部材の載置面の領域でプリント配 線板上に配置されている。しかし出力構造部材の設置後はこの貫通接触部がもは や目視不能であって、検査プロセスのためにアクセスすることができない。更に 、付加的な部分によって形成する必要のある電気的な絶縁に伴って問題が発生し 、これが結果的に熱伝達損失を招くことになっている。 発明の開示 これに対し請求項1に記載の特徴を備えた本発明の装置は、出力構造部材から 低熱部への良好な熱の導出が保証されていると同時に、種々の出力構造部材の電 気的な絶縁性が相互に保証されかつ多くは金属製である低熱部(ケーシング又は ケーシングの底部プレート)に対しても保証されているという利点を有している 。電気絶縁部はもはや覆われていなくて良好に目視可能であり、かついつでも検 査することができる。電気絶縁路は小さな公差で製作可能である。更にこの形式 でのプリント配線板の大量生産は、付加的な作業工程が必要でないため、経済的 で価格的に有利である。またこの形式にあっては、付加的な絶縁部分、付加的な 組立作業、内方に位置する高価な貫通接触部又は熱を導出するための付加的な金 属コア等が全く必要でない。 請求項2以下に記載の手段によって、請求項1で述べた特徴の更に有利な別の 構成が可能である。この装置は多層プリント配線板に対してもまた2面状に積層 された簡単なプリント配線板に対しても共に適合可能である。 図面の簡単な説明 本発明の実施例を図面に図示し、次の説明でこれを詳しく説明する。その際図 1は出力構造部材を備えたプリント配線板の縦断面図、図2は出力構造部材側の プリント配線板の上面の平面図、図3及び図4は実施例の夫々1つの変化態様の 図、図5a乃至図5dはプリント配線板の1つの熱伝導層の夫々の平面図、を図 示している。 実施例の説明 図1には符号10で出力構造部材が表わされており、運転の際には特にシリコ ンチップ30内に発生する出力構造部材10の熱、つまり損失熱を導出しなけれ ばならない。出力構造部材10及びシリコンチップ30は、出力構造部材10内 に組み込まれた、例えば金属から成る冷却プレート11によってプリント配線板 13のろう付け面12上に配置されている。プリント配線板13は、所謂多層板 として多層状に構成されていて、電気的な絶縁材料、例えばガラス織布から成る 多くの層14,15,16から成っている。これらの層の間には、つまり層14 及び15の間乃至は層14及び16の間には夫々1つの銅層22及び21が配置 されている。この銅層21,22に対しては、伝熱性でかつ電導性の特性を有し ている別の材料も考えられる。更に出力構造部材10のためのろう付け面12と 層15との間には銅から成る層17が位置している。更にろう付け面12と出力 構造部材10の当接面との外方のプリント配線板13内には貫通接触部18とし て、プリント配線板13の全肉厚を貫通して案内されている多数の孔が形成され ている。貫通接触部18の 壁は伝熱性かつ電導性である薄い層20から成っている。図1に基く構成の場合 に重要な点は、層17と貫通接触部18のための層20との間に電気的な絶縁区 間19が形成されているという点である。図1では簡単な形式でこの絶縁区間1 9が層17と層20との間の接続を遮断することによって形成されている。つま り層17及び層20は相互に直接連結されていない。更に層20は管リベットと 同じように層14,15,16の上面に当接している。 図1によれば出力構造部材10の両側に熱導出用の貫通接触部18が形成され ており、このため中間層21,22が、プリント配線板13を貫通して一方の貫 通接触部18の層20から他方の貫通接触部18の層20へ到達できるようにな っている。図2から明らかなように、出力構造部材10は多数の貫通接触部18 によって周辺を枠状に取り囲まれている。このことは夫々、中間層21,22が 貫通接触部18の層20に接続されている一方で、層17はいかなる位置におい ても貫通接触部18の層20と直接的な接触を行っていないことを意味しており 、その結果、層15が電気的な絶縁材料から成っているので、層17と層20と の間に電気的な絶縁区間19が形成されうるようになっている。貫通接触部18 の数と、出力構造部材10が周囲を貫通接触部18によって取り囲まれているか どうかということとは、導出されるべき熱の量に依存 している。つまりこの量によって貫通接触部18の幾何学的な配置及び構成が影 響を受けるようになっている。このための特別な構成が図3及び図5に更に詳し く述べられている。 更に銅層が、プリント配線板13の底部層23として貫通接触部18の壁20 を相互に結合している。この底部層23を介してプリント配線板13は、図1に は図示されていない、所謂熱を導出するための低熱部として役立つ冷却部材又は ケーシング部分上に固定されている。しかしまた、プリント配線板13をケーシ ング内で自由に掛止して固定し、それによって熱の導出を実現することも可能で あろう。この低熱部は多くの場合金属的にアース電位に導かれている。 図1には矢印によって、出力構造部材10から低熱部へ向う熱の流れが表わさ れている。特にシリコンチップ30で発生した出力構造部材10の損失熱は、組 み込まれた冷却プレート11からろう付け面12を介し伝熱性で電導性であるプ リント配線板13の層17に到達する。この層17を介して熱は、層15に導か れかつ電気的な絶縁材料から成る層15及び伝熱性の層22を介して貫通接触部 18の伝熱性の層20に案内される。貫通接触部18から熱は、伝熱性の底部層 23に直接導かれる。特に飽和のために層22によって受容されえない熱は、電 気的な絶縁材料から成る層14に到達しかつ伝熱性の材料から成る次の層21に より受容されて貫通接触部18の層20に案内される。この位置から熱は更に、 底部層23を介して熱低下部に導かれる。 図3に図示された実施例の場合には、プリント配線板13aが載置面23aと 共に全面的に低熱部35上に載置されているのではなくて、部分的にだけ低熱部 35に接触している。このことは、プリント配線板13aが低熱部35を超えて 突き出ていることを意味している。プリント配線板13aは、図1及び図2に基 く実施例と同じ様に所謂多層として形成された多層状のプリント配線板として構 成されている。貫通接触部18aも同じ様に、出力構造部材10a近傍の側方で プリント配線板13a内に形成されている。図1に基く実施例と異なっている点 は、伝熱性の層17aが少くとも部分的に貫通接触部18aの伝熱性の層20a に接触しているという点である。このことは、層17aが一方の側では、例えば 図3では左側では、その位置が形成された貫通接触部18aの層20aに結合さ れている一方で、他方の側では、つまり図3では右側では、層17aとその位置 に位置する貫通接触部18aの層20aとが接触していないことを意味している 。出力構造部材10aと低熱部35との間で必要な電気絶縁は、伝熱性の層22 a,21a及び23aが夫々交互に貫通接触部18aの層20aにだけ接続され ている一方で、他方の側では夫々層20aとの接触が 行われていないということによって達成されている。このためこの場合も、出力 構造部材10aと低熱部35との間の電気的な絶縁区間19が形成されうるよう になっている。図3に基く実施例の場合には、層22a及び23aが図面の左側 においてその位置に位置する貫通接触部18aの層20aに接触していない、つ まり絶縁区間19b及び19cを有している。これとは異なって層17a及び層 21aは、図3の右側において貫通接触部18aの層20aに接触していない、 つまりこちら側には電気的な絶縁区間19d及び19eが存在している。これに よって更に、出力構造部材10aから低熱部35への良好な熱伝達が行われ、か つ同時に出力構造部材10と低熱部35との間に電気的な絶縁が存在し得るよう に保証されている。図3に基く実施例の場合熱伝達自体は、図1に基く実施例の 説明と同じ様に行われる。低熱部35上に位置していない貫通接触部18aを熱 伝導的な材料、例えばはんだ36を用いて充填することによって、出力構造部材 10aから低熱部35への熱伝達を顕著に改善することができる。 図4に基く実施例の場合には出力構造部材10bが部分的に貫通接触部18c を覆っている。この実施例の場合幾つかの貫通接触部18cからのアクセスがで きないようになっている。しかしその外の構造は図3の場合と同一である。 図5a乃至図5cには、交互の電気的な絶縁部つまり電気的な絶縁区間19の 形成状況が図示されている。図5aには、貫通接触部18cと層17cとの開口 部が平面図で図示されている。層17cと貫通接触部18cの層20cとの間の 絶縁区間36aが図5aの右側にみえている。図5bからは、貫通接触部18c の層20cと層22cとの間の電気的な絶縁区間36bが他方の側に位置してい るのが認められる。図5cからは、絶縁区間36cが図面の右側におしやられて いて、層21cと貫通接触部18cの層20cとの間に位置しているのが認めら れる。図5dには基板23cが図示されていて、左側に位置する貫通接触部18 cの層20cに対する電気的な絶縁区間36dが認められる。つまり各平面内で 各伝熱層21,22,23上には、少くとも1つの絶縁区間19,36が存在し ているのを認めることができる。Detailed Description of the Invention                  Equipment consisting of printed wiring boards Technical field   The invention relates to a device consisting of a printed wiring board according to the preamble of claim 1. . Background technology   In known devices of this type, the heat generated in one or more output structural members In many cases, it is difficult to lead out to the low heat part. The reason is the printed wiring board A large number of prints with different potentials on at least one of the two surfaces It has a wiring circuit, which intersects with each other and is allowed to intersect with the low temperature part. Because it has not been done. For example according to German Patent No. 3505167 For example, the heat of the output structural member can be guided to the lower side of the printed wiring board through the through contact part. And are known. This penetrating contact portion is printed on the mounting surface of the output structural member. It is placed on the line plate. However, after installation of the output structural member, this penetrating contact Or invisible and inaccessible for the inspection process. Further , Problems with the electrical insulation that needs to be formed by the additional parts , Which results in heat transfer losses. Disclosure of the invention   On the other hand, the device of the present invention having the features of claim 1 is Good heat transfer to the low heat section is guaranteed, while at the same time the power of various output structural members is Low heat parts (casing or Has the advantage that it is also guaranteed against the casing bottom plate) . The electrical insulation is no longer covered, is well visible and can be inspected at any time. Can be inspected. The electrical isolation path can be manufactured with small tolerances. Further this format Mass production of printed wiring boards in the market is economical because no additional work steps are required. It is advantageous in terms of price. Also, in this form, additional insulating parts, additional Assembly work, expensive inwardly located piercing contacts or additional gold to dissipate heat No genus core is required at all.   Claim 2 A further advantageous alternative of the features mentioned in claim 1 is provided by the measures described below. Configurable. This device also has a two-sided stack for multi-layer printed wiring boards. Both can be applied to the simple printed wiring board described above. Brief description of the drawings   Embodiments of the invention are illustrated in the drawings and will be explained in more detail in the following description. At that time 1 is a vertical cross-sectional view of a printed wiring board provided with an output structure member, and FIG. FIG. 3 is a plan view of the upper surface of the printed wiring board, and FIGS. 3 and 4 show one variation of the embodiment. FIGS. 5a to 5d are plan views of one heat conductive layer of a printed wiring board, respectively. Shows. Example description   An output structural member is represented by reference numeral 10 in FIG. 1, and is particularly suitable for operation during operation. The heat of the output structural member 10, that is, the heat loss, generated in the chip 30 must be derived. I have to. The output structural member 10 and the silicon chip 30 are inside the output structural member 10. Printed wiring board with cooling plate 11 made of, for example, metal It is arranged on the brazing surface 12 of 13. The printed wiring board 13 is a so-called multilayer board. As a multi-layered, electrically insulating material, eg woven glass It consists of a number of layers 14, 15, 16. Between these layers, layer 14 And 15 or between layers 14 and 16 there is one copper layer 22 and 21 respectively Has been done. The copper layers 21 and 22 have the characteristics of heat conductivity and electric conductivity. Other materials are also possible. And a brazing surface 12 for the output structural member 10 A layer 17 made of copper is located between the layers 15. Further brazing surface 12 and output A penetrating contact portion 18 is formed in the printed wiring board 13 outside the contact surface of the structural member 10. A large number of holes that are guided through the entire thickness of the printed wiring board 13 are formed. ing. Through contact portion 18 The wall consists of a thin layer 20 which is both heat conductive and electrically conductive. In case of configuration based on Fig. 1 The important point is that there is an electrical insulation between the layer 17 and the layer 20 for the through contact 18. The point is that the space 19 is formed. In Fig. 1, this insulation section 1 is shown in a simple form. 9 is formed by breaking the connection between layers 17 and 20. Tsuma The layers 17 and 20 are not directly connected to each other. Further layer 20 is a tube rivet It also abuts the upper surfaces of layers 14, 15 and 16.   According to FIG. 1, the through contact portions 18 for heat extraction are formed on both sides of the output structure member 10. Therefore, the intermediate layers 21 and 22 penetrate the printed wiring board 13 and one of them penetrates. From the layer 20 of the through contact portion 18 to the layer 20 of the other through contact portion 18, ing. As is apparent from FIG. 2, the output structural member 10 has a large number of through contact parts 18 Is surrounded by a frame. This means that the middle layers 21 and 22 are Whereas the layer 17 is connected to the layer 20 of the through contact 18, the layer 17 is in any position. Means that it does not make direct contact with the layer 20 of the penetrating contact portion 18. As a result, since layer 15 is made of an electrically insulating material, layers 17 and 20 are An electrically insulating section 19 can be formed between them. Penetrating contact part 18 And the output structural member 10 is surrounded by perforation contacts 18 Whether it depends on the amount of heat to be derived are doing. That is, this amount affects the geometrical arrangement and configuration of the penetrating contact portion 18. It is supposed to be affected. The special construction for this is described in more detail in FIGS. Well described.   Further, the copper layer is used as the bottom layer 23 of the printed wiring board 13 for the wall 20 of the through contact portion 18. Are linked to each other. As shown in FIG. 1, the printed wiring board 13 is provided through the bottom layer 23. Is a cooling member (not shown) serving as a so-called low heat part for deriving heat or It is fixed on the casing part. However, again, the printed wiring board 13 It is also possible to freely hang it in the ring and fix it, thereby realizing heat dissipation. Ah In many cases, the low heat part is metallically led to the ground potential.   In FIG. 1, the arrows indicate the heat flow from the output structural member 10 to the low heat portion. Have been. In particular, the heat loss of the output structural member 10 generated in the silicon chip 30 is A heat-conducting and electrically-conducting process is carried out from the cooling plate 11 embedded through the brazing surface 12. The layer 17 of the printed wiring board 13 is reached. Heat is conducted to layer 15 through this layer 17. Through-contact through the layer 15 made of electrically insulating material and the heat-conductive layer 22. Guided to 18 heat transfer layers 20. The heat from the penetrating contact portion 18 is the heat conductive bottom layer. Directly to 23. Heat that cannot be accommodated by layer 22, especially due to saturation, is The layer 14 of electrically insulating material is reached and the next layer 21 of thermally conductive material is reached. It is better received and guided to the layer 20 of the through contact 18. The heat from this position is further It is guided to the heat lowering portion through the bottom layer 23.   In the case of the embodiment shown in FIG. 3, the printed wiring board 13a serves as the mounting surface 23a. Both are not entirely placed on the low heat portion 35, but only partially on the low heat portion. Is in contact with 35. This means that when the printed wiring board 13a exceeds the low heat section 35, It means protruding. The printed wiring board 13a is based on FIG. 1 and FIG. In the same manner as in the embodiment, a so-called multilayer printed wiring board is formed. Has been established.
