More Information
Summary:A process to bond VCSEL arrays to submounts and printed circuit boards is provided. The process is particularly suited to large area thin and ultra-thin VCSEL arrays susceptible to bending and warping. The process integrates a flatness measurement step and applying appropriate combination of pressure prior to bonding the VCSEL array to the submount or a printed circuit using a vacuum flux-less bonding process. The process is very promising in making very good quality bonding between the VCSEL array and a submount or a printed circuit board. The process is applied to construct optical modules with improved flatness that may be integrated with other electronic components in constructing optoelectronic systems.
