of charge each capacitor stores discharges on each triggering cycle thereby controlling the amount of light energy output by each respective lamp for example the triggering profile can include a time duration value to normalize a particular lamp 39 s output energy with a baseline flash energy output as noted above the lamp exposure system is preferably controlled using a programmed computer as shown in fig2 fig5 is a schematic view of the wiring connections between the various modules according to a preferred embodiment fig6 a 6d is a schematic of the wiring of each of the lamps in greater detail the u201c main controller u201d module connects the controller i o lines to an external pc for programmable control of the lamp exposure system fig7 is a flowchart illustrating the operation according to one embodiment of the present lamp exposure system at step 61 the light energy output from each lamp is measured as described above based on the measured energy level a triggering profile is determined for each lamp step 62 and the triggering profile is stored in memory step 63 this procedure can be performed at regular intervals such as daily or weekly to calibrate the system next a substrate such as pcb having a photo resist polymer material on it is placed into position for exposure step 64 the ultraviolet lamps are flash triggered according to each lamps triggering.
