Title: Printed circuit board
Inventor: OGIWARA YOSHIAKI
IPC: H05K3/42
Filed: 1989-01-27
Abstract: PURPOSE:To enhance reliability of connection of circuit layers with one another by forming a recess of a specific depth along a direction substantially coincident with the circumferential direction of a conduction hole on the inner wall face of the conduction hole having a metal plated layer. CONSTITUTION:A recess of depth of 10-100mum is formed along a direction substantially coincident with the circumferential direction of a conduction hole 3 on the inner wall face of the conduction hole 3 for electrically connecting circuit layers with one another. Accordingly, since the plated layer 4 in the conduction hole 3 is long in the axial direction of the hole, thermal stress per unit length of the plated layer 4 in the axial direction of the hole can be reduced. Since a recess 5 is provided, the thermal deformation of the conduction hole 3 tends to easily occur by the provision of the recess 5, thereby preventing a stress from concentrating at the corner of the plated layer 4 (a part connecting the circuit layer) due to the thicknesswise thermal expansion of the insulating layer 2a. Thus, the connecting reliability can be improved.
