TEST DEVICE USING LIGHT PROJECTION TO TEST ADHERENCE OF ELECTRICAL DEVICE

摘要

A test device is used for projecting light into a to-be-tested product. The product includes a sidewall, the sidewall defines an opening, and the opening communicates with an internal space of the product. The test device includes a collimated light source and a support element. The collimated light source is used for emitting collimated light into the internal space through the opening. The support element supports the collimated light source. An included angle between the collimated light and the sidewall is about 5 degrees.
