PURPOSE:To provide a printing plate suitable for applying a creamy solder to a rugged printed substrate by printing, by a method wherein a metallic plate is provided with a recessed part on one side thereof, and is etched on the opposite side thereof so as to leave a metallic part in the periphery of said recessed part to thereby provide a projected part. CONSTITUTION:The printing plate 8 is used for stably applying a creamy solder to a flexible substrate 1-1 in order to fix electronic parts 7 provided in a recessed part 6 of the printed substrate 1. The printing plate 8 is produced by a method wherein a metallic sheet 2 is provided with a recessed part 3 on one side thereof by etching, small holes 4 are provided in the recessed part 3, and the other side of the sheet 2 is etched so as to leave the metallic part in the periphery of said recessed part 3 to provide the projected part 5. In the condition wherein the projected part 5 is mated to the recessed part 6 of the printed substrate 1, the creamy solder is applied by printing, whereby the solder can be applied to the electronic parts 7 located in the recessed part 6. |
