As the rolling wheel with the resistance position is selected, when the sun-shading curtain stops the motion, the sun-shading curtain is not only under the action of the friction force of the contact surface, but also is regulated by the component force of magnetic force in the horizontal direction, and the hollow glass further has the automatic position-limiting function, the operation difficulty is reduced and the operation hand feeling is improved.

The invention discloses a printed circuit board production and processing method in the technical field of printed circuit board production and processing. The printed circuit board production and processing method comprises the following steps of: step 1, cutting a printed circuit board into a required shape; 2, placing the printed circuit board on a clamping device, and starting equipment to use the clamping device to clamp the printed circuit board according to any shape of the circuit board; 3, printing the circuit board by using a drill bit; 4, starting a clamping device to release the circuit board; and 5, taking down the printed circuit board from the clamping device. The problems that electronic devices on the printed circuit board are heated, fixed target objects are obviously inconsistent, hole sites are fixed, deformation of the printed circuit board is aggravated if things go on like this, the welding stability of the electronic parts is reduced, and the printed circuit boards are different in shape, so that other irregular printed circuit boards cannot be well adapted to clamping, and printing fails due to offset in the later printing process are solved.
