The invention discloses a
sintering fixture for a micro channel
semiconductor laser and a
sintering method thereof. The
sintering fixture comprises a positioning base and an adjustable cover plate, wherein the adjustable cover plate is connected onto the positioning base; a
concave surface is arranged on the positioning base; two sides of the
concave surface are bosses; the adjustable cover plate comprises a main body, a pressing block and a pressing block adjustment mechanism, the main body is provided with a pressing block groove, and the pressing block is arranged inside the pressing block groove via the pressing block adjustment mechanism. The micro channel
semiconductor laser sintering method by the above device comprises steps: a micro channel
heat sink sintered with a
semiconductor laser bar
chip, an insulated sheet and the adjustable cover plate are sequentially connected onto the positioning base from bottom to top and fixed by using bolts, and the above well-fixed entire fixture is sealed in a protection cover shell with
nitrogen and is placed on a heating table for sintering. According to the sintering fixture for the micro-channel semiconductor laser and the sintering method thereof, the structure is simple, the cost is low, the operation is simple, convenient and reliable, and through one-time sintering, quick and accurate fixed connection among the bar
chip of the micro-channel semiconductor laser, the micro-channel
heat sink, the insulated sheet and a negative
electrode sheet can be realized.
