Description

Substrate heating carrier Technical Field The utility model relates to the technical field of semiconductor device processing, in particular to a substrate heating carrier. Background As shown in fig. 5, a carrier for heating a power module, the carrier comprises a plate 1, a plurality of rectangular through holes 10 are uniformly distributed on the plate 1, an embedded ring groove 11 is formed at the upper end of the rectangular through holes 10, R grooves 12 are formed at four corners of the embedded ring groove 11, the power module comprises a substrate 2, a plurality of electronic components 20 and a plurality of pins 21 are welded on the substrate 2, the carrier is used for fixing the substrate 2, when the electronic components 20 and the substrate 2 are welded, the substrate 2 is firstly placed on the embedded ring groove 11, then the power modules to be welded are transferred to a heating device, each heating block of the heating device penetrates through the rectangular through holes 10, the upper ends of the heating blocks are contacted with the lower wall of the substrate 2, solder paste is melted in a heating mode, and then the electronic components are welded, and in this mode, the uniformity of heating of the substrate 2 can be ensured. Disclosure of utility model The utility model provides a substrate heating carrier, which solves the defects in the prior art, solves the problem that the substrate is inconvenient to take and place, and has strong practicability. In order to achieve the object of the present utility model, the following techniques are proposed: The utility model provides a base plate heating carrier, including the rectangular plate, the rectangular plate has offered a plurality of rectangular holes from top to bottom throughout, rectangular hole evenly distributed is on the rectangular plate, the annular has been offered to the upper end of rectangular hole, the arc wall has been offered at four angles of annular, the embedded groove has been offered respectively to rectangular hole length direction's both ends, wear to be equipped with the pole of wearing in the bottom of embedded groove, wear the lower extreme of pole and be equipped with the end cap, the end cap is located the downside of rectangular plate, wear the upper end of pole and have the roof through threaded connection, the step groove has been offered to the inboard end of roof, wear the upper end cover of pole and be equipped with the spring, the spring is located between roof and the bottom of embedded groove; A pair of kidney-shaped holes are respectively formed in two sides of the rectangular hole in the width direction, movable screws are movably arranged in the kidney-shaped holes, upper clamping plates are connected to the upper ends of the movable screws located on the same side through threads, and the upper clamping plates are located on the upper side of the rectangular plate.
