PURPOSE:To assure the stability of the protection of mounted parts as well as the seating of printed board by a method wherein the front protector in substantially C-shaped higher than the fitting levels of semiconductor integrated circuit elements is fitted to the surface side front part of the printed substrate while a rear protector higher than circuit elements and opposite to the front protector is fitted to the surface side rear part. CONSTITUTION:The title printed board device is provided with a front protector 11 in substantially C-shape higher than the fitting levels of semiconductor integrated circuit elements 2-6 fitted tot he surface side front part of the printed board 1, a rear protector also in substantially C-shape higher than said circuit elements 2-6 fitted to the surface side rear part opposite to the front protector 11 as well as the screws 13, 14 fixing the front and rear protectors 11 and 12 from the rear surface side of the printed board 1. In such a constitution, said front and rear protectors 11, 12 serving both as reinforcement members of the substrate 1 can be grasped when the substrate device is handled. Through these procedures, the scratching of the mounted parts on the printed board as well as the accidental grasping of part and radiating fins can be avoided while enabling the seating of the printed substrate 1 to be stabilized. |
