a processing method of a red copper coil plate for a special motor comprises the following steps:
step 1: firstly, compensating the line segments of the graph in a segmented manner in a design stage (see figure 1), wherein the line width of each segment of a single line is gradually changed, less compensation (compensation of 0.025mm) is added in a dense area 1 with the distance smaller than 0.015mm, more compensation (compensation of 0.075mm) is added in a sparse area 2 with the distance larger than 0.015mm, and a special film for an inner exposure machine is drawn after the design is finished;
step 2: cutting large copper plates (shown in figure 3) with corresponding sizes according to the cutting size, properly leveling after cutting because the plates are provided in coils, and removing a surface oxidation layer through an inner layer pretreatment line;
and step 3: coating a wet film on an inner layer coating machine, wherein the edges of a transverse clamping plate are needed, and drying treatment is carried out after the wet film is coated on the two sides of the plate;
and 4, step 4: the semi-automatic exposure machine is adopted for production, when upper and lower films are erected, exposure operation is carried out after alignment parameters are adjusted to +/-0.025mm, and when the alignment precision deviation is large, the edges of etched lines are not parallel and level, so that the line width is influenced;
and 5: after the conventional parameter is imaged, special etching parameters (the etching speed is reduced to 1.5m/min, and the etched large plate is shown in figure 4) are adopted, the final line width and the line edge are adjusted to meet the requirements, the etching speed is a key influence parameter because the copper plate is thicker than the copper on the surface of the conventional plate and the non-reserved area needs to be etched through, and whether the line width of each section shown in figure 2 meets the requirements or not needs to be confirmed after etching;
step 6: manually separating plates, cutting connecting copper wires (shown in figure 5) between PCS (PCS) to form a delivery unit plate (a finished single PCS picture is shown in figure 3), wherein the unit is not damaged in the cutting process, the periphery is leveled, and packaging and delivery can be carried out after the FQC inspection and the FQA sampling inspection are qualified;
therefore, the invention is produced by applying partial manufacture procedure of the PCB, the required copper wires are covered by the wet film, the redundant copper is removed by chemical etching to form single copper wires (shown in figure 6) which are arranged in a 360-degree rotation manner, the production efficiency is high, the cost is low relative to laser processing, and all parameters of a finished product completely meet the requirements of customers.
