Abstract
A particulate removal and lens bond test device includes a base for receiving a waffle pack holding a plurality of optical subassemblies (OSAs) to be tested and an associated applicator for applying a predetermined flow of gas across the OSAs to remove loose particulates and to test the bond strength of the lens on the OSA. The applicator includes a flow regulator and a plurality of orifices arranged to direct the flow of gas onto each individual OSA in the waffle pack.
Claims15
A test device for removing loose particulates from optical subassemblies (OSAs) arranged in an array on a waffle pack and for concurrently testing a bond strength of lenses bonded to the OSAs, said test device comprising:
- a base having a receiving area configured for removably receiving and supporting for testing, in a predetermined test position on the base, a waffle pack holding a plurality of OSAs;
- and
- an applicator including a gas flow regulator connectable to a gas supply for generating a predetermined flow of gas from the gas supply and configured for directing the predetermined flow of gas onto the OSAs arranged on the waffle pack supported on the base, said applicator being movable between a first test position in which at least a portion of the applicator is remotely spaced from said base so as to permit positioning of the waffle pack on the base for testing and removal of the waffle pack from the base after completion of testing, and a second testing position in which the applicator and base are disposed in close proximity to define therebetween a substantially closed space in which the waffle pack is nonremovably located for operative testing of the plural OSAs held in the waffle pack by application of said predetermined flow of gas onto the plural OSAs to remove loose particulates from the OSAs and test the bond strength of the OSA lenses.
