The invention discloses a high-efficiency cooling motor with a compact structure, which comprises a connecting end cover, a front end cover, a stator core and a rear end cover, a stator winding is set in the stator core, and the center of the connecting end cover, the front end cover and the rear end cover The rotating shaft is installed, and the outer wall of the rotating shaft is fitted with a rotor iron core. The outer wall of the rotor iron core is fitted with a magnetic steel, and the connecting end cover, the front end cover, the stator core and the rear end cover are fitted together and the cooling water pipe is installed. The cooling water pipe includes Inlet and outlet pipes, straight pipes and connecting pipes. The straight pipes pass through the front end cover, stator core and rear end cover. The outer wall of each straight pipe is screwed with two compression nuts, and the two compression nuts are respectively attached to the front end cover and the rear end cover. The rear end cover, the two ends of the connecting pipe are respectively connected to the ends of two straight pipes, one end of the inlet and outlet pipe is connected to the end of the straight pipe, the inlet and outlet pipes, the straight pipe and the connecting pipe are connected to form a cooling water pipe, and the inlet and outlet pipes pass through Connect the end cap. The invention has the advantages of simple and compact structure, low cost, good cooling effect and convenient assembly and disassembly.

The invention discloses a manufacturing method of a printed circuit board. The manufacturing method comprises the following steps: providing a substrate; forming a copper foil on the substrate; forming a green oil layer on the surface of the copper foil; windowing the green oil layers of at least one contact bonding pad regions, wherein each contact bonding pad region corresponds to one shrapnel and multiple subwindows are formed each contact bonding pad region in the windowing step; performing wave soldering so as to form tin ingots with shapes similar to those of the subwindows, wherein the tin ingots of each contact bonding pad region form a contact bonding pad electrically with the shrapnel. The invention further discloses a printed circuit board. The contact welding pan consists of multiple tin ingots, i.e., the tin ingot area is reduced, so that the tin of the tin ingots is uniform and even, and the tin ingots can be effectively contacted with the shrapnels; the arc height of a tin surface is controlled below 0.2mm, and normal installation of the shrapnels is not influenced.

The invention discloses a cable mounting bracket for 5G communication and a mounting method thereof. The cable mounting bracket comprises a fixed plate, a placement plate, a cable main body, a partition plate, a clamping rod, a first rubber pad, a spring, a rubber block, a second rubber pad, a protection plate, a connecting rod, a moving plate, a sliding groove, a sliding block, a first bolt, a guide plate, a fixed rod, a fixed groove, a fixed block, a second bolt, a limiting groove and an expansion screw. The cable mounting bracket is simple in structure and convenient to operate, cable bodies are prevented from being staggered during installation and arrangement, the problem that the cable bodies are prone to displacement when an existing mounting bracket is used is solved, and the cable bodies can be placed more stably during installation; the problem that the top end of an existing mounting bracket is not provided with a protection structure is solved, operation is easy and convenient, and normal installation of the cable bodies is not affected; and the cable mounting bracket solves the problem that the existing cable mounting bracket cannot perform auxiliary guiding on the cable bodies during use, and the applicability of the mounting bracket is improved.
