A pyrotechnic igniter arrangement, especially for occupant protection devices in motor vehicles, includes a single common carrier substrate, an electronic assembly arranged on the carrier substrate in an electronic zone, an electrically ignitable ignition bridge arranged on the carrier substrate in a pyrotechnic zone, and a pyrotechnic charge in the pyrotechnic zone. A mechanical decoupling or parting feature, such as a frangible link or an elastically bendable neck, is provided in the carrier substrate between the pyrotechnic zone and the electronic zone, so that forces arising during ignition of the pyrotechnic charge are not transmitted through the carrier substrate into the electronic zone. The decoupling feature breaks or elastically yields when a load exceeding a prescribed threshold is applied thereto. The electronic assembly is protected from damage due to excessive loads, and remains functional even after ignition of the pyrotechnic charge.

The board is classified into first and second areas (121, 120) where values of opening sizes of the stencil along a squeegee moving direction are smaller than and not smaller than a threshold, and a speed of the squeegee at the first area is made slower than that at the second area. Upon an occurrence of print standby time during a printing operation, the print standby time is measured, and at a resumption of printing with the print standby canceled, the paste placed on the stencil during the standby time is screen-printed, by moving the squeegee at an adjusted print speed lower than the reference print speed based on a relationship between the print standby time and a print time due to the adjusted print speed after the resumption of printing.
