しまう可能性が高いという課題を有していた。Problems to be Solved by the Invention However, in the conventional configuration described above, static electricity (generally several KV to tens of KV) charged on the human body or human clothing passes through the gap 50 shown in FIG. 7, as shown by arrow A in FIG. If a signal line is discharged to a signal line near the edge of the printed circuit board 25, there is a high possibility that electronic components, particularly semiconductor components, connected thereto will be destroyed.

It has a structure comprising a plurality of fine ground pattern parts and (plate patterns).

とができる。The present invention has the above-described configuration, so that even if static electricity is discharged to the board from an exterior gap, etc., the basic earth pattern placed around the board and the fine ground pattern placed from the basic ground pattern to the periphery of the board can be used. Because the pattern (board pattern) completely discharges to the ground line and is absorbed into the power supply section of the main body through the ground line, it is possible to prevent destruction of electronic components.
実施例
以下１本発明の一実施例の電子部品取付装置について図
面を参照しながら説明する。Embodiment 1 An electronic component mounting apparatus according to an embodiment of the present invention will be described below with reference to the drawings.
第１図は本発明の〒実施例を示すものであシ、前述の第
４図（、）のプリント板に相当する要部平面図である。FIG. 1 shows an embodiment of the present invention, and is a plan view of a main part corresponding to the printed board shown in FIG. 4 (2) described above.
プリント板周辺に基幹アースパターン部１を配しさらに

部１より微細アースパターン（１板パターン）部２を配
している。また基幹アースパターン部１からはアース線
３を通して図示しない本体部のアースに接続されるよう
になっている。A basic earth pattern part 1 is arranged around the printed board, and a fine earth pattern (one-board pattern) part 2 is further arranged from the basic earth pattern part 1 toward the edge of the printed board. Further, the basic ground pattern section 1 is connected to the ground of the main body section (not shown) through a ground wire 3.
なお、従来の構成と同一の要素については同一番号を付
与して説明を省略する。Note that elements that are the same as those in the conventional configuration are given the same numbers and their explanations are omitted.
第２図は電子部品取付装置の要部拡大断面図である。FIG. 2 is an enlarged sectional view of the main parts of the electronic component mounting device.
図中、６は半田レジスト、４は回路パターンである。In the figure, 6 is a solder resist, and 4 is a circuit pattern.

ス部に放電することで回路内の電子部品の破壊を防止す
ることができる。As described above, according to this embodiment, by wiring the ground line around the electronic component mounting device, all the static electricity discharged through the exterior gap is transferred from the fine ground pattern section 2 to the basic ground pattern section 1 and the ground line. By discharging to the main body grounding part through 3, it is possible to prevent destruction of electronic components in the circuit.

。As shown in Figure 2, the solder resist 6 covers the parts of the printed board that cannot be soldered, so if the ground pattern is not placed all the way to the periphery of the printed board, the solder resist will act as an insulator and the static electricity will flow smoothly. It does not discharge electricity.
また、プリント板を周縁まで全てパターンを配すると、

不要となるので、基幹アースパターン部と微細アースパ
ターン部によるアースパターン配線構成は有効である。Also, if you arrange the pattern all the way to the periphery of the printed board,
When cutting a printed board with a mold, there is a high possibility that edge cracking, pattern peeling, etc. will occur. Therefore, by arranging the fine earth pattern parts radially from the basic earth pattern part to the peripheral part as shown in Figure 1, it is possible to extremely reduce edge cracks, and the die cutting accuracy can also be improved by arranging the fine earth pattern parts radially from the basic earth pattern part to the peripheral part. 'If it is extended sufficiently, it becomes unnecessary, so the earth pattern wiring configuration consisting of the basic earth pattern part and the fine earth pattern part is effective.

る。Effects of the Invention As described above, according to the present invention, by arranging a basic ground pattern around the board and further arranging a fine ground pattern from the main ground pattern to the periphery of the board, static electricity discharged from the periphery of the board can be grounded. It can be absorbed into the line.

できる。In addition, it is only necessary to devise the pattern wiring of the board, and there is no need to separately apply wiring such as aluminum foil to the exterior part or insert a resistor in series with the signal line to prevent electrostatic damage.
This is extremely effective in preventing destruction of the electronic component mounting device.
