Inventor: OKADA OSAMU
IPC: H05K3/34
Filed: 1994-10-28
Abstract: PURPOSE: To improve connection strength, by forming an aperture in a specified part of a connection lead which bridges a lead hole formed in a board, and forming a swell of solder on the inner periphery of the aperture. CONSTITUTION: A connection electrode 32 corresponding with an outer lead 15 on the upper side of a TAB tape 11 is formed on the upper surface of a printed wiring board 31. A slit type aperture 23 is formed in a specified part of an outer lead 15. Solder (connection part member) 33 is interposed between the connection electrode 32 and the upper side outer lead 15 of the TAB 11, and fused by a process like hot-air pressurizing. When the solder is hardened, the outer lead 15 is connected with the connection electrode 32. In this case, on the upper surface of the connection electrode 32, swells 34a are formed on both side surfaces of the upper side. A swell 34b is formed also on the inner periphery of the aperture 23. By the effect of the swell 34b formed on the inner periphery of the aperture 23, connection strength can be improved.

Abstract: PURPOSE:To improve the yield without impairing a printed circuit board by preventing wickets to function as a sliding guide from being brought in contact with a substrate as a body to be conveyed by using a substrate gripper during the conveyance in a cure furnace. CONSTITUTION:A substrate 2 as a body to be heated is conveyed by an input conveyer 1 and lifted by a pair of wickets 6, so as to be fed in a furnace. In this case, the wickets 6 are erected, and a jig 7 as a substrate gripper is slid on the wickets 6, so as to pinch the substrate 2 (position H). Next, when the wickets 6 are straight erected, the substrate 2 is held in the floated state by the jig 7 (position I). Since the wickets 6 are attached with angle, the taper of the jig 7 is not directly come into contact with the substrate 2, the balance is kept. The substrate 12 is slipped off from the taper part of the jig 7 by the inclination of the wickets 6 to be generated by the own weight of the substrate 2, and the jig 7 is naturally dropped inside the wickets 6, thereby the substrate 2 is released.
