本発明は微細かつ多端子接続用の多電極コネクターの製
造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of manufacturing a multi-electrode connector for fine and multi-terminal connections.
近年、ＩＣのパターンの微細化に伴い、ＩＣ電極の効率
の良い配置構成が種々考えられている。In recent years, with the miniaturization of IC patterns, various efficient arrangement configurations of IC electrodes have been considered.
この中でも細密化に適した電極配置として、ＩＣ表面の
全面に渡って電極を形成したマｌ−ＩＪックス状電電極
配置面積効率が最も高（、広く応用され始めている。こ
の電極配置に於ては、ＩＣの素子領域上に電極を配置す
るため、ボンディング時の熱応力や機械的圧力により、
素子ダメージを受ける危険性が高いといった問題点を有
しており、素子ダメージの少ない接続構造が望まれてい
た。又、さらには、多数個のＩＣを１枚の基板上に搭載
する場合、交換性に優れた接続構造は必須であり、この
問題に対してもボンディングによる接続方式は、必ずし
も良好な方式であるとは言えなかった。Among these, as an electrode arrangement suitable for miniaturization, the multi-IJ square electrode arrangement, in which electrodes are formed over the entire surface of the IC, has the highest area efficiency (and is beginning to be widely applied. Since electrodes are placed on the IC element area, thermal stress and mechanical pressure during bonding may cause
The problem is that there is a high risk of element damage, and a connection structure that causes less element damage has been desired. Furthermore, when mounting a large number of ICs on a single board, a connection structure with excellent interchangeability is essential, and a connection method using bonding is not necessarily a good method to solve this problem. I couldn't say that.
これらの要求事項を満足する接続構造の１つの候補とし

電極コネクターを介してＩＣを基板に圧接する接続構造
が考えられている。この様な多電極コネクターを用いた
接続構造は、ボンディング時に於ける素子ダメージも無
く、ＩＣの交換性にも優れており、多電極ＩＣを多数個
接続する構造に対し大変優れた構造である。As a candidate for a connection structure that satisfies these requirements, a connection structure is being considered in which an IC is pressed against a substrate via a multi-electrode connector in which groups of conductive parts are provided vertically and horizontally in correspondence with the electrodes of the IC. . A connection structure using such a multi-electrode connector is free from element damage during bonding and has excellent IC exchangeability, and is a very superior structure to a structure in which a large number of multi-electrode ICs are connected.

試みられていた。Conventionally, the multi-electrode connector as described above is shown in Fig. 5 (
A base material in which ferromagnetic fine powder such as nickel is uniformly dispersed in silicone rubber 54 as shown in al.
The ferromagnetic fine powder is concentrated and oriented in a predetermined location by applying a partial magnetic field at an appropriate temperature in a jig that has a magnetic pole group at a position corresponding to the electrode group, and the silicone rubber is cured. A manufacturing method has been attempted in which a multi-electrode connector sheet 52 having a unidirectional conductive group 53 is molded and then cut along the dot-dashed line in the figure to form a multi-electrode connector 51.
しかし、この様な従来技術によると、多電極コネクター
５１の導電部群５６の形状は、強磁性微粉末の混入量、
導電部周辺の体積、磁界及び温度条件によって決定され
、特に導電部周辺の体積効果は大きく、多電極コネクタ

太きいため、配向量の増大をもたらし、このため導電部
の広がりや導電部間の強磁性微粉末残りを生じ、歩留り
の低下をもたらしたり、接続時のショート原因となる等
、種々の問題を引起していた。However, according to such conventional technology, the shape of the conductive part group 56 of the multi-electrode connector 51 depends on the amount of mixed ferromagnetic fine powder,
It is determined by the volume, magnetic field, and temperature conditions around the conductive part, and the volume effect around the conductive part is particularly large.The outermost conductive part of the multi-electrode connector 51 has a larger surrounding volume than other parts, so the orientation amount This causes various problems, such as spreading of the conductive parts and residual ferromagnetic powder between the conductive parts, leading to a decrease in yield and causing short circuits during connection.

The objective is to provide a multi-electrode connector that has a high yield and enables stable connections.

末の均一配向性を高めた方法である。In order to achieve the above object, the manufacturing method of the present invention arranges conductive part rows at intervals approximately equal to the conductive part group pitch of the multi-electrode connector on the outer periphery of the effective area of the multi-electrode connector, thereby making the multi-electrode connector effective. This method improves the uniform orientation of ferromagnetic fine powder to a group of conductive parts within a region.
