Abstract
Heat assisted magnetic recording uses a laser diode (LD) to provide energy during the writing process. The LD is bonded on a submount chip which is referred to as the Chip-On-Submount-Assembly (COSA). COSA devices undergo burn-in and testing in COSA burn-in fixtures, which include a first non-conductive layer having through holes and a second conductive layer having first openings. The second conductive layer is disposed over the first non-conductive layer with each of the first openings overlaying one of the through holes. COSA burn-in fixtures also include a third non-conductive layer having second openings that are larger than the first openings. The third non-conductive layer is disposed over the second conductive layer with each of the second openings overlaying one of the first openings, which forms pockets with a seat on the conductive layer for disposing the LD with one electrode in contact with the conductive layer.
