Title: Production of multilayer printed wiring board
Inventor: IKAWA KEIKO
IPC: H05K3/06
Filed: 1993-12-28
Abstract: PURPOSE:To form a blind via hole in which the plating thickness of outer layer is minimized while preventing layer exfoliation. CONSTITUTION:A through hole 2 is made previously through the outer layer material, i.e., a copper clad laminate 1, of a multilayer printed wiring board and a wiring pattern 3 is formed on the inner layer surface side. A dry film resist 18 is laminated on the inner layer surface of the outer layer material and exposed with scattering light from the outer layer surface side thus exposing the dry film resist 18 only at the through hole 2 part. It is then developed and an inner layer material 8, previously applied with an arbitrary wiring pattern, is laminated on the outer layer material 6 through a glass cloth 7 impregnated with a thermosetting semicured resin before hot press. The through hole of the multilayer printed wiring board is then processed and plasma processing is effected in order to remove the dry film resist 18 left on the inner layer face side of the outer layer material 6 before a copper plating layer is applied. Finally, a wiring pattern is formed on the surface of outermost layer thus producing a multilayer printed wiring board having a blind via hole.

Title: Wet developer for developing electrostatic latent image
Inventor: KAWAKADO KOICHI
IPC: G03G9/12
Filed: 1989-12-26
Abstract: PURPOSE:To lessen the unequal development and to allow efficient development with a smaller amt. of the developer to be used by specifying the concn. of a coloring agent in a developing stage to 2 to 10wt.%. CONSTITUTION:The prepd. developer 5 is put between a transparent electrode 2 and a metallic plate 3 and the entire part of the device is heated to maintain the developer 5 in a liquefied state and thereafter, a voltage is impressed between the transparent electrode 2 and the metallic plate 3 to develop the positive charged coloring agent on the transparent electrode 2. The concn. of the coloring agent 5 in the developing stage is specified to 2 to 10wt.% at this time. Since the concn. of the coloring agent is sufficiently high, the sufficient development concn. is obtd. only in the thin developer layer 5 in the extreme neighborhood of the electrostatic latent images formed on a photosensitive body and since the shorter migration resistance of the coloring agent particles is necessitated, the generation of convection in the developer is obviated. The development of good uniformity without having the unequal concn. is executed in this way and the amt. of the necessary developer is decreased.
