IPC: H01L23/28
Filed: 1990-08-18
Abstract: PURPOSE:To prevent the separation of molding resin from a lead frame, prevent cracks in the molding resin, and improve the humidity resistance of a device by applying a multiple-layer coating to the reverse surface of a lead frame. CONSTITUTION:The reverse surface of a lead frame is plated with a metal coating 5, such as silver, which offers good adhesion to the lead frame. A second metal coating 6 such as copper, different in the coefficient of thermal expansion from the first metal coating, is applied to the first metal coating. Another metal coating, such as copper or zinc, is applied to the second metal coating. In this manner, metal coatings are sequentially applied using metals that are little different in the coefficient of thermal expansion. The first coating 5 should have a coefficient of thermal expansion close to that of the lead frame 4, while the last coating 7 has a coefficient of thermal expansion close to that of the molding material 2.

Title: Painting method
Inventor: TANAKA NORITAKA
IPC: B05D7/14
Filed: 1987-09-03
Abstract: PURPOSE:To position a material to be coated to a posture to allow easy operation so that operator's labor is decreased by changing the rotating posture position of the material to be coated in a post stage after drying of a primer coat. CONSTITUTION:For example, an automobile body W as the material to be coated is transferred to a carriage D having a rotating device from a hanger after completion of primary coating. The body W held to the carriage D is so set that the rotating axial line direction thereof is the horizontal axial line, i.e., the longitudinal direction of the body W. The body W is then rotated via a revolving shaft 5 by means of such an air motor 29 which rotates the body to the rotating posture position where the lower face of the body faces lateral or upward. This body is subjected to sealer packing and under-coating and is dried. The polishing of the coated surface is further executed while the rotating posture position of the body W is adequately changed, by which the coated surface subjected to the primer coating is smoothed. As a result, the operator is capable of making the operation with ease without changing the posture and position.
