Abstract
An electrically insulative adhesive coating for a circuit board used with a photoflash lamp array to provide sequential firing of the flash lamps. The circuit board includes the lamp firing circuitry along with switching elements connected in said circuitry and the insulative coating prevents electrical shorting of the circuitry. In a preferred embodiment, the coating material may be an organic polymer and may be provided with openings to permit radiation transfer from the flashing lamps to the underlying switches which are radiation-responsive.
