1. It is not impossible to drill holes on the solder pad. If you are willing to spend money on small holes, the laser hole and plugging process should be fine;a. For BGA pads with a spacing of less than or equal to 0.5mm, they must be very dense and holes must be drilled on the pads; The difficulty and cost of PCB plate making process have increase...

I saw a device without any sensors, and the servo can return to the origin very accurately. The servo is from Yaskawa, and the encoder is incremental. The servo motor rotates in a circular motion, sometimes it cannot rotate less than one turn, and once the action is completed, it returns to the origin. Sometimes it may take several rotations to ret...
