Embodiment 1

[0032] exist figure 1 In this case, when the power switch of the exposure apparatus 100 is turned on, the lighting circuit 7 supplies power to all the discharge lamps 1 . Usually, it takes several minutes for the discharge lamp 1 to start up completely. Immediately after the power switch of the exposure apparatus 100 is turned on, the control unit 9 turns on the first switch 10 connected to the first incandescent lamp 2 in the light source device 4 to supply a constant current from the constant current power supply 8 . After a predetermined time (for example, after 10 seconds) from the conduction of the first switch 10, the voltage across the first incandescent lamp 2 is measured by the measuring part 11, and the result is sent to the comparing part 12, and the comparing part 12 compares the The result and the voltage distribution ranges of a plurality of incandescent lamps for authentic product detection registered in the comparison unit 12 in advance will be sent to the det...

Embodiment 2

[0038] exist figure 1 Among them, the elements different from those in Example 1 are the measurement unit 15 (the internal resistance is the resistance 15a), the comparison unit 16, and the determination unit 17, and the other elements are the same. Description of the same elements as those in Embodiment 1 is omitted. Immediately after the exposure device 101 turns on the power switch, the first switch 10 connected to the first incandescent lamp 2 in the light source device 4 is turned on to supply a constant current from the constant current power source 8 . Immediately thereafter, the first measurement of the voltage across the first incandescent lamp 2 is performed by the measurement unit 15 , and the result is sent to the comparison unit 16 . Then, after a predetermined time (for example, after 10 seconds) from the first measurement, the second measurement of the voltage across the first incandescent lamp 2 is carried out by the measurement part 15, and the result is sent...

Abstract

The invention relates to a light source device which is constituted of discharge lamps serving as light sources; incandescent lamps detecting whether or not the discharge lamps are genuine products; and reflector containers mounted with the discharge lamps and the incandescent lamps. The light source device determines whether or not the discharge lamps are the genuine products by lighting the incandescent lamp while the discharge lamps are being lit and detecting whether or not each voltage between both ends thereof falls within a predetermined voltage distribution range for detecting the genuine products.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201610225945.2, the application date is April 13, 2016, and the invention title is "exposure device and its inspection method". technical field [0002] The present invention relates to an exposure apparatus for exposing printed wiring boards and the like, including an incandescent lamp for detecting whether a discharge lamp as a light source is a genuine product, and an inspection method thereof. Background technique [0003] Conventionally, a printed wiring board in which a metal such as copper is used to form a wiring pattern on a substrate made of resin or glass epoxy is used for mounting components on electronic equipment. Photolithography is used to form wiring patterns on these printed wiring boards. In this method, a photoresist as a photosensitive chemical is applied to the entire surface of a substrate on which a metal layer serving as wiring is forme...
