Title: Manufacture of flexible printed wiring board
Inventor: ODAJIMA SATOSHI
IPC: H05K3/12
Filed: 1993-02-09
Abstract: PURPOSE:To stabilize the dimensional accuracy after printing drying by applying an annealing process and a moisture absorption process to an insulation film before printing a conductive pattern thereby to prevent a wrinkle from occurring when the film is mounted on a printing table. CONSTITUTION:First, an insulation film is annealed to stabilize the effect of the subsequent process. Then, the film is left to stand in a high-humidity bath to cause the film to absorb moisture. This method is advantageous because the process for wiping off drops of water can be omitted, and the coefficient of moisture absorption can be adjusted by the period of time during which the film is left to stand. Further, by heating the high-humidity, the moisture absorption to increase the absolute humidity, the moisture absorption rate can be increased to effectively perform the moisture absorption process. This allows the manufacture of a flexible printed wiring board requiring a high dimensional accuracy, selection of dimensional failure of the conductive pattern is not necessary, and the lifetime of the screen printing board ca be prolonged, whereby the manufacture cost can be reduced.
