Title: Printed wiring board
Inventor: MATSUI TETSUO
IPC: H05K3/34
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To realize improvement in stress resistance against an external force, by elongating the length of a boundary line between a solder region and a non-solder region of a soldering portion of a land of a printed wiring board for mounting circuit components thereon so as to be greater than the length of an outer arc. SOLUTION: When an external force F acts in a right-hand direction, a reactive force is developed in a direction opposite to the external force F on a copper foil pattern surface portion. The stress concentrates on a boundary line 10 between a solder region 8 and a non-solder region 9. This boundary line 10 is formed by a curved line. The ratio of the total length L of the left half of the boundary line 10 to the total length L0 of the left half of an ordinary' circle may be increased by approximately L/L0 =(πR+αR)/(πR)=1+α/π, where α>0, that is, by about 1.1 times or more. The value of the diameter 2R of a land 5 is designed to be about 1.5-4.0mm while the length of the boundary line 10 is designed to be 2.0-10.0mm, thus causing α/π to be approximately 1.1-5.0.  With the magnitude of the external force F being approximately 1-2kg.m, increasing L/L0 by about 1.5 times causes an increase in the stress resistance by about 1.5 times, thus enabling improvement in stress resistance.

Filed: 1997-12-08
Abstract: PROBLEM TO BE SOLVED: To easily remove a semiconductor device without damaging a resin sealing body in removing it from a substrate frame, by stacking solder resist which has tight adhesion with a resin material on the main face of the substrate frame in accordance with a gate part into which the resin material is injected. SOLUTION: When a gate 29 is to be bent, a part where solder resist 30 is provided has tight adhesion with the resin member and the other part which is metal-plated has weak adhesion. Thus, a part except for the part where resist 30 is provided is easily peeled off. On adding force from the back side of a wiring substrate 14 which is pushed back and removing the substrate 14 from the substrate frame 11, the gate 29 on the resist 30 is in a state of remaining on resist, and only a substrate 14-side forming the semiconductor device is removed from the frame 11. Thus, a part between the gate and the resin encapsulant is bent in a designed method at a fixed position so as to remove it without damaging the resin encapsulant.
