Analysis of Influence of PCB Drilling Spindle Selection on Machining Quality

•

5G hardware products are developing towards high integration, thinning and miniaturization. Therefore, the wiring density of circuit boards inside 5G products is increasing, and the small holes with a drilling diameter of less than 0.3mm account for more than 80%, while the IC carrier board ( Especially BGA boards and HDI boards) have higher hole density and precision requirements. These dense small holes put forward more stringent requirements on the speed of the processing spindle.

•

In addition to the shortcomings of the above-mentioned two points of insufficient processing capacity, the spindle of ordinary PCB drilling machine also has a long start-stop time and elevated operating temperature, which also have a significant impact on the processing efficiency and stability of the air-floating drilling machine.

•

In order to ensure the universality of PCB drilling rigs, the processing spindle must not only meet the performance of "large load, high torque, high speed", but also meet "low temperature rise, quick start and stop" in terms of stability and processing efficiency. CHIKIN PCB drilling machine high-speed electric spindle, with its advantages of high speed, high torque and high precision, can meet the processing needs of one machine for multiple purposes and improve the overall processing efficiency.
