半導体センサーに於いては特性のばらつきを吸収するためにオフセッ卜調整や 傾き調整をする必要があるが、調整用のモニター端子やデータ転送端子及び書き 込み端子等のチェック端子が図５や図６の様に形成されていると、図７及び図８ に示した様に、調整のためピンプローブ２２がチェック端子用パターン３ｅに当 たると必ず回路基板３が曲がる。回路基板が曲がるとボンディング部やモールド を通じてＩＣチップも曲がり、半導体センサーを形成するトランジスターのチヤ ンネル長やチャンネル幅の形状変化すなわちセンサーの特性変化を引き起こす。 つまり従来の構造はセンサーの特性を正確に測定できず調整後のセンサーの値が 理想値とずれてしまうという致命的な欠点を有していた。 In semiconductor sensors, it is necessary to perform offset adjustment and tilt adjustment to absorb variations in characteristics, but check terminals such as the monitor terminal, data transfer terminal, and write terminal for adjustment are shown in Figure 5 and Figure 6. When the pin probe 22 hits the check terminal pattern 3e for adjustment as shown in FIGS. 7 and 8, the circuit board 3 is always bent. When the circuit board is bent, the IC chip is also bent through the bonding portion and the mold, causing a change in the channel length or channel width of the transistor forming the semiconductor sensor, that is, a change in the sensor characteristics. In other words, the conventional structure had a fatal defect that the sensor characteristics could not be accurately measured and the adjusted sensor value deviated from the ideal value.
【０００４】 本考案はかかる問題点を除去するものであり、その目的とする所は、半導体セ ンサーの調整後にセンサーの特性を正確に測定できず調整後のセンサーの値が理 想値とずれない品質の高い電子時計を提供することにある。The present invention eliminates such a problem, and an object of the present invention is to make it impossible to accurately measure the characteristics of the sensor after the adjustment of the semiconductor sensor, so that the value of the adjusted sensor deviates from the ideal value. The aim is to provide high quality electronic watches.

本考案の電子時計は、チェック端子を透孔内部に張り出した片持ばり形状に形 成しているため、半導体センサーの特性のばらつきを調整時にピンプローブが当 たっても、パターン（銅箔）のみが変位し回路基板は曲がらない。従って、調整 時と調整後に半導体センサー特性変化は起こらない。 Since the electronic timepiece of the present invention is formed in a cantilever shape with check terminals protruding into the through hole, even if the pin probe hits when adjusting the variation in the characteristics of the semiconductor sensor, only the pattern (copper foil) However, the circuit board does not bend. Therefore, the characteristics of the semiconductor sensor do not change during and after adjustment.

以下、ＩＣチップ内の半導体温度センサーにより水晶発振器の温度補償を行う 高精度電子腕時計を例に本考案を詳細に説明する。 Hereinafter, the present invention will be described in detail by taking a high-precision electronic wrist watch that performs temperature compensation of a crystal oscillator by a semiconductor temperature sensor in an IC chip as an example.
【０００８】 本実施例の電子腕時計に於いては、半導体温度センサーに特性変化が起こった 状態で水晶発振器の歩度温度特性を補償すると、温度特性が傾いたり上下に凸に なったりして、年差１０秒〜２０秒といった高精度を補償できなくなってしまう ため、半導体温度センサーの特性変化は極力押える必要がある。In the electronic wristwatch according to the present embodiment, if the rate temperature characteristic of the crystal oscillator is compensated in the state where the characteristic change occurs in the semiconductor temperature sensor, the temperature characteristic may be tilted or may be convex and downward, and Since it becomes impossible to compensate for the high accuracy of 10 to 20 seconds, it is necessary to suppress the characteristic change of the semiconductor temperature sensor as much as possible.
【０００９】 本実施例の電子腕時計の平面図を図１に断面図を図２に示す。図１及び図２に 於いて、ｌはｌａ部に内蔵している半導体温度センサーの情報に基づいて水晶振 動子２の２次温度特性を補償する機能を有するアナログ電子時計用のＣＭＯＳー ＩＣチップ、２は約３２７６８ＨZ で発振し２次温度特性を有する音叉型水晶振 動子、３はＩＣチップｌをフェイスダウンボディングでまた水晶振動子２を半田 付けで装着したフレキシブル回路基板、４は合成樹脂で成形され各部品の位置決 め用のダボや各部品を受けたり逃げたりするためのさらいを有し、さらに各部品 を固定するための金属製ねじピンが打ちこまれている時計体のべースとなる地板 、５は水晶振動子２，回路基板３，コイル６，ステータ９等の部品をねじ１４， ｌ５，ｌ６，ｌ７により地板４に固定する回路押え板、６はコイル、７はコイル ６の磁心、８はコイルリード基板、９はステータ、１０は時計用酸化銀電池、１ １は巻真、ｌ２は規正レバー、ｌ３は輪列受、ｌ４〜ｌ８はねじ、ｌ９は電池マ イナス端子、２０は電池絶縁板、２ｌはＩＣチップｌを回路基板３に確実に装着 するためのモールドである。FIG. 1 is a plan view of the electronic wrist watch of this embodiment, and FIG. 2 is a sectional view thereof. In FIGS. 1 and 2, 1 is a CMOS IC for an analog electronic timepiece having a function of compensating for the secondary temperature characteristic of the crystal oscillator 2 based on the information of the semiconductor temperature sensor built in the la part. chip, the tuning fork crystal oscillation Doko having 2 oscillates about 32768H Z 2 order temperature characteristic, the flexible circuit board 3 is equipped with or crystal resonator 2 and the IC chip l facedown body ring by soldering, 4 Is a watch that is molded from synthetic resin and has a dowel for positioning each part, a wiper for receiving and escaping each part, and a metal screw pin for fixing each part is struck. A base plate serving as a base of the body, 5 is a circuit retainer plate for fixing parts such as the crystal oscillator 2, the circuit board 3, the coil 6, the stator 9 and the like to the base plate 4 with screws 14, 15, 16, and 17; , 7 is a carp 6 a magnetic core, 8 a coil lead substrate, 9 a stator, 10 a silver oxide battery for watches, 11 a winding stem, 12 a train wheel setting lever, 13 a train wheel bridge, 14 to 18 screws, 19 a battery minor A terminal, 20 is a battery insulating plate, and 2l is a mold for securely mounting the IC chip 1 on the circuit board 3.
【００１０】 図３に回路基板３の詳細な平面図を示す。図３に於いて３ａはスリッ卜、３ｂ は水晶振動子装着部、３ｃ，３ｄは水晶振動子用リードパターン、３ｅ，３ｆ， ３ｇ，３ｈ，３ｉ，３ｊ，３ｋはチェック端子用パターンである。チェック端子 用パターン３ｅ，３ｆ，３ｈ，３ｉ，３ｊは回路基板３に穿設された透孔内に張 出すように形成され、チェック端子用パターン３ｇ，３ｋは回路基板３の外緑か ら切り込まれたスリットの内部に張出すように形成されている。FIG. 3 shows a detailed plan view of the circuit board 3. In FIG. 3, 3a is a slit, 3b is a crystal unit mounting portion, 3c and 3d are crystal unit lead patterns, 3e, 3f, 3g, 3h, 3i, 3j and 3k are check terminal patterns. The check terminal patterns 3e, 3f, 3h, 3i, 3j are formed so as to project into the through holes formed in the circuit board 3, and the check terminal patterns 3g, 3k are cut from the outer green of the circuit board 3. It is formed so as to project into the inside of the inserted slit.
【００１１】 平断面図や図３の詳細図に示した様に本実施例の回路基板３は、ＩＣチップ１ の１a 部に形成される半導体温度センサーと水晶振動子２のそれぞれの温度特性 を測定するためのモニター端子や、水晶振動子２の温度特性に併せて半導体温度 センサーと水晶振動子２をそれぞれの温度特性を測定するためのモニター端子や 、水晶振動子２の温度特性に併せて半導休温度センサーのオフセッ卜調整や傾き 調整をするためのデータ転送端子、及び転送されたデータをやはりＩＣチッブ１ 内に内蔵されている半導体不揮発性メモリーに書き込むための書き込み端子等の チェック端子用パターン３ｅ，３ｆ，３ｇ，３ｈ，３ｉ，３ｊ，３ｋを片持ちば り形状のオーバーハングパターンとしているため、図４に示した様に、半導体温 度センサーの温度特性を測定する時や調整する時にピンプローブ２２がチェック 端子用パターンに当たっても、パターン（銅箔）のみが変位し回路基板自身は曲 がらない。従ってＩＣチップｌも曲がらずｌａ部に半導体温度センサーを形成す る卜ランジスターの形状変化も起きないため、調整後のセンサーの温度特性は水 晶振動子２の温度特性に合致したものとなる。尚、３ｅ〜３ｋは片持ちばりの支 持部付近を細くして、ピンプローブが接触した時にこの部分に応力集中が起こり 確実にバターンのみが変位するようにしている。As shown in the plan sectional view and the detailed view of FIG. 3, the circuit board 3 of the present embodiment shows the temperature characteristics of the semiconductor temperature sensor and the crystal resonator 2 formed in the 1a portion of the IC chip 1. A monitor terminal for measuring, a monitor terminal for measuring the temperature characteristics of the semiconductor temperature sensor and the crystal resonator 2 together with the temperature characteristics of the crystal resonator 2, and a temperature terminal for the crystal resonator 2 Check terminals such as a data transfer terminal for offset adjustment and tilt adjustment of the semi-conducting temperature sensor, and a write terminal for writing the transferred data to the semiconductor nonvolatile memory also built in the IC chip 1. Since the patterns 3e, 3f, 3g, 3h, 3i, 3j, 3k are cantilevered overhang patterns, as shown in FIG. Even hit the pin probe 22 is checked terminal pattern when time and adjusted for measuring the temperature characteristics of Nsa, the circuit board itself only the pattern (copper foil) is displaced is unwilling song. Therefore, the IC chip 1 is not bent and the shape change of the semiconductor transistor forming the semiconductor temperature sensor does not occur in the la portion, so that the temperature characteristic of the sensor after adjustment matches the temperature characteristic of the crystal oscillator 2. . For 3e to 3k, the supporting part of the cantilever is thinned near the supporting part so that when the pin probe comes into contact, stress concentration occurs in this part and only the pattern is surely displaced.
【００１２】 また本実施例の電子腕時計に於いては，回路基板３の固定をねじｌ４周辺及び ねじ１５の周辺で行ない、ＩＣチップｌの周辺の基板は完全にフリーになるよう に地板４ａの高さ及び回路押え板５の曲げ高さを設定し、固定部からＩＣチップ ｌまでの距離を長くして、ねじ１４及びｌ５がゆるんだとき、ＩＣチップｌ近辺 の回路基板の曲がり具合が変化しないようにしている。Further, in the electronic wrist watch of this embodiment, the circuit board 3 is fixed around the screw 14 and around the screw 15, and the board around the IC chip 1 is completely free of the main plate 4a so as to be completely free. When the height and the bending height of the circuit pressing plate 5 are set to increase the distance from the fixed portion to the IC chip 1 and the screws 14 and 15 are loosened, the bending degree of the circuit board near the IC chip 1 changes. I try not to.
【００１３】 さらに本実施例の回路基板は、ＩＣチップｌ装着部と水晶振動子２の間にＩＣ チップｌに沿ったスリット３ａを設けているため、水晶振動子２の固定状態が変 化し回路基板の３ｂ部の高さが変化しても、ＩＣチップｌ装着部の回路基板が変 化しないようにしている。また、スリット３ａをオーバーハングしている水晶振 動子用リードバターン３ｃ及び３ｄを、スリッ卜３ａとほぼ平行に配線し長くす ることによつて、やはり水晶振動子装着部３ｂに生じる高さの変化がＩＣチップ に影響を与えないようにしている。Further, in the circuit board of the present embodiment, since the slit 3a along the IC chip 1 is provided between the mounting portion of the IC chip 1 and the crystal resonator 2, the fixed state of the crystal resonator 2 is changed and the circuit is changed. Even if the height of the portion 3b of the board changes, the circuit board of the IC chip 1 mounting portion does not change. Further, the lead patterns 3c and 3d for the crystal oscillator that overhang the slit 3a are wired substantially parallel to the slit 3a, and the length is also increased. Changes in the IC do not affect the IC chip.
【００１４】 以上詳細に説明してきた様に、本実施例の高精度電子腕時計は、回路基板３の 固定状態の変化やピンプローブの接触の影響により半導体温度センサーの特性が 変化しないため、機械的要因によりセンサーの特性経時変化しない信頼性の高い 高精度電子時計を歩留り良く生産できる。As described in detail above, the high-precision electronic wrist watch of the present embodiment is mechanically operated because the characteristics of the semiconductor temperature sensor do not change due to the change of the fixed state of the circuit board 3 and the contact of the pin probe. Due to the factors, it is possible to produce a highly accurate high-precision electronic timepiece with high yield that does not change over time due to sensor characteristics.
【００１５】 又、回路基板単体の状態でも時計体に組み込まれた状態とほぼ同様の固定状態 をつくってやれば、回路基板３を時計体に組み込んだ時に半導体温度センサーの 特性変化が起こらないので、回路基板単体の状態で水晶発振器とセンサーの温度 特性を測定し温度特性の調整することができるため、測定及び調整のための装置 を小型，簡易化できる。本実施例の場合、回路基板３がフレキシブルでありテー プ（フイルム）キャリア方式を用いて温度特性の測定や調整をライン化できるた め、測定及び調整の自動化と装置の簡易化が容易にできる。Further, even if the circuit board alone is made into a fixed state that is almost the same as the state where it is incorporated in the timepiece, the characteristic change of the semiconductor temperature sensor does not occur when the circuit board 3 is incorporated in the timepiece. Since the temperature characteristics of the crystal oscillator and the sensor can be measured and the temperature characteristics can be adjusted with the circuit board alone, the device for measurement and adjustment can be made compact and simple. In the case of this embodiment, since the circuit board 3 is flexible and the measurement and adjustment of the temperature characteristics can be made into a line by using the tape (film) carrier system, automation of the measurement and adjustment and simplification of the apparatus can be facilitated. .
【００１６】 また、本実施例の高精度電子腕時計は回路基板単体の状態で温度特性をつくり 込むことができるため、市場でのアフターサービスも回路基板の交換で対応でき 、修理費の低減と修理期間の短縮化が可能である。Further, since the high-precision electronic wrist watch of the present embodiment can create temperature characteristics in the state of the circuit board alone, after-sales service in the market can also be dealt with by exchanging the circuit board, reducing repair costs and repairing. The period can be shortened.
【００１７】[0017]
本考案の電子時計は、半導体センサーの調整用のチェック端子を回路基板の外 形内に形成された透孔内部に張出した片持ばり形状に形成したため、半導体セン サーの特性のばらつきを吸収するための調整時にピンプ口ーブが当たっても、パ ターン（銅箔）のみが変形し回路基板自体は曲がらない。従ってｌＣチップも曲 がらず半導体センサーの特性変化が起きないため、センサーの特性を正確に測定 でき、調整後の半導体センサーの特性は理想的なものとなり、品質の高い半導体 センサーを有する電子時計を歩留まりよく提供することができる。 Since the electronic watch of the present invention has the check terminal for adjustment of the semiconductor sensor formed in the shape of a cantilever that extends into the through hole formed in the outer shape of the circuit board, it absorbs the variation in the characteristics of the semiconductor sensor. Even if the ping pout is hit during adjustment, only the pattern (copper foil) will be deformed and the circuit board itself will not bend. Therefore, the IC chip does not bend and the characteristics of the semiconductor sensor do not change. Therefore, the characteristics of the sensor can be measured accurately, and the characteristics of the adjusted semiconductor sensor become ideal. It can be provided with high yield.
【００１８】 更に、パターンのうち水晶振動子が導電接続される水晶振動子接続部は、回路 基板の外周部から内部に向かって切り込まれ形成されるスリットによって片持形 状に形成された部位の端部近傍に配置されることにより、回路ブロックとして完 成して時計体に組込んだ後ばかりでなく、時計体に組み込む際に、水晶振動子が 他の部材例えば地板や中枠に接触しても、基板の曲がりを片持形状に形成された 部位の基部で吸収することができる。Further, in the pattern, the crystal unit connecting portion to which the crystal unit is conductively connected is a cantilever-shaped portion formed by a slit formed by cutting inward from the outer peripheral portion of the circuit board. Since it is placed near the end of the crystal unit, the crystal unit will not come into contact with other members such as the main plate or the middle frame not only after it is completed as a circuit block and installed in the watch body, but also when it is installed in the watch body. However, the bending of the substrate can be absorbed by the base of the cantilevered portion.
【００１９】 従って、基板の変形によるＩＣチップの電極であるパッド部やＩＣチップ自体 への機械的負荷を軽減し、ＩＣチップの導通の信頼性やＩＣ内蔵半導体センサー 等の内部動作を安定させる事ができるものである。Therefore, it is possible to reduce the mechanical load on the pad portion which is the electrode of the IC chip and the IC chip itself due to the deformation of the substrate, and to stabilize the reliability of the conduction of the IC chip and the internal operation of the IC built-in semiconductor sensor and the like. Is something that can be done.
【００２０】 また、ＩＣチップのパッドと水晶振動子接続部はスリッ卜上にスリットの長手 方向に斜め又は平行に配置された導電配線により接続されることにより、回路ブ ロック組み込み持の水晶振動子接続部とＩＣチップ装着部との間に生じる断面的 な高さの違いを、スリッ卜上の導電配線で吸収し、ＩＣチッブ装着部に基坂変形 を伝えないようにすることができるものである。Further, the pad of the IC chip and the crystal resonator connecting portion are connected by a conductive wiring arranged obliquely or parallel to the longitudinal direction of the slit on the slit, so that the crystal resonator with the circuit block incorporated therein is provided. The cross-sectional height difference between the connection part and the IC chip mounting part can be absorbed by the conductive wiring on the slit so that the base plate deformation is not transmitted to the IC chip mounting part. is there.
【００２１】 従って、前述したチェック端子が回路基板の透孔内にオーバーハングして形成 されていることとあいまって、基板の片持形状部に水晶振動子を接続するととも に、回路基板に形成されたスリッ卜上に水晶振動子用導電配線を配置することに より、ＩＣチップ装着部の回路基板の変形を防ぎＩＣチップに内蔵された半導体 センサーの動作も安定するという効果を最大限に引き出せるもである。Therefore, together with the above-mentioned check terminals formed overhanging in the through holes of the circuit board, the crystal unit is connected to the cantilever-shaped portion of the board and formed on the circuit board. By arranging the conductive wiring for the crystal unit on the slit, it is possible to maximize the effect of preventing the circuit board of the IC chip mounting part from being deformed and stabilizing the operation of the semiconductor sensor built in the IC chip. It is also.
【００２２】 なお、実施例ではＩＣチップ内の半導体温度センサーにより水晶発振器の温度 補償を行なう電子腕時計を例に説明したが、本考案は温度や圧力等を測定するた めめ半導体センサーを有する電子卓上計算器や電子温度計等の小型電子機器にも 適用できるものである。In the embodiment, the electronic wristwatch in which the temperature of the crystal oscillator is compensated by the semiconductor temperature sensor in the IC chip has been described as an example, but the present invention is an electronic wristwatch for measuring temperature and pressure. It can also be applied to small electronic devices such as desktop calculators and electronic thermometers.
