Title: Multilayer interconnection board
Inventor: TAKENAKA HIROSHI
IPC: H05K3/46
Filed: 1999-12-21
Abstract: PROBLEM TO BE SOLVED: To enhance reliability for connection between a pad and a non-through connection hole part by enhancing an adhesive strength between the pad and a board material. SOLUTION: A pad 16, which is connected to an IVH 18 while being jointed to a connection terminal 13 of a quartz oscillator 12, is formed on a first substrate material 2 at the top of first - third substrates 2-4, where a first - fourth wirings 5-8 are formed, and an insulating film 17 is so formed as to cover the outer peripheral part of the pad 16, except for a part joint region 19. The insulating film 17 raises the adhesion strength of the pad 16 to the first substrate material 2, thus the pad 16 is suppressed from releasing off the first substrate material 2 under thermal stress, which occurs when the connection terminal 13 of the quartz oscillator 12 is jointed to the pad 16. So cracking between the pad 16 and IVH 18 is suppressed for enhanced connection reliability.
