Abstract
PURPOSE:To prevent smear and thin spot, by performing screen-printing of solder resist ink with (specified) viscosity or of component marking ink, only on the part where a tent is pitched by using a pattern whose diameter is larger than that of a through hole by a specified range. CONSTITUTION:Ordinary solder resist printing is performed with clear for a tenting through hole part (section 7). Then screen-printing is performed with a diameter larger than that of the through hole by 0.03-1.0mm to obtain a tenting film 8. For ink 5 to be used, solder resist ink 5 or component marking ink is desirable, and for its viscosity, the range of 100-2000 poise is preferable. When it is less than 100 poise, the ink is apt to flow into the hole, and the mask is hardly formed. When it is larger than 2000 poise, the output of the ink is small, and grinding becomes inferior, so that a tenting film is difficult to be formed.
