Abstract:
A process for improving the performance of the sliding rheostat of 5G communication high-frequency signal board with the sliding rheostat slides along between two bonding pads, includes the following steps: outer layer etching; resin plugging: a. plugging the resinous ink into the pre-plugging position; b: baking, baking on the baking plate of the oven after the plugging is finished; board polishing: using a ceramic brush to process the plugged board, then using a non-woven fabric blush to polish the surface that is polished by ceramic brush. The present invention provides a process for improving the performance of the sliding rheostat of 5G communication high-frequency signal board. The resin plugging method is used to plug the gap between the conductors of the sliding rheostat, so as to prevent the sliding rheostat from being unable to slide due to the altitude difference between conductors of the high-frequency signal board.
