Abstract
Contacts on an integrated circuit chip are arranged at a lower seat of a base on the integrated circuit chip. Each of the contacts includes a main part, two bowed wing parts located at both sides of the main part, two elastic arms extended upward from one end of each wing part, two clamp parts at the upper edge of the elastic arms and a bearing part for adhering a tin ball. A support part extended from the bottom edge of the wing part to support against the bearing part. The above mentioned structure allows the bearing part of the contact to be fixed on the same plane during assembling and leveling, thus preventing any deformation resulting from being pressed for facilitating better adhesion of the tin ball.
Claims5
Contacts on an integrated circuit chip, being arranged at a lower seat of a base on the integrated circuit chip and each of the contacts comprising:
- a main part, two bowed wing parts located at both sides of the main part, two elastic arms extended upward from one end of each wing part, two clamp parts at the upper edge of the elastic arms and a bearing part for adhering a tin ball;
- characterized in that:
- a support part extended from the bottom edge of the wing part to support against the bearing part;
- whereby, the above mentioned structure allows the bearing part of the contact to be fixed on the same plane during assembling and leveling, thus preventing any deformation resulting from being pressed for facilitating better adhesion of the tin ball.
