PRINTED WIRING BOARD OF ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To enable a printed wiring board to be efficiently manufactured by providing the printed wiring boards with mounting holes which are never filled up with solder even when board bodies are subjected to a flow soldering process. SOLUTION: After electronic parts are mounted on a board body 1, the electronic parts are soldered to the circuit pattern of the board body 1 through a flow soldering process for the formation of a printed wiring board for an electronic apparatus. A frame ground 5 which electrically connects the board body 1 to the case of the electronic apparatus is formed by removing a resist 4 from the board body 1 in the radial direction of a mounting hole 1a bored in the board body 1. When the board main body 1 is subjected to a flow soldering process, solder attached to the frame ground 5 is divided into parts in the radial direction, so that the mounting hole 1a is hardly filled up with solder. A soldering correction operation for removing solder filled in the mounting hole 1a can be dispensed with after a flow soldering process is carried out, so that a printed wiring board can be markedly improved in manufacturing efficiency.
