Processing method for improving V-CUT resistance welding removal
By performing deep-controlled milling on the ceramic-filled plate PCB in front of the V-CUT, the green oil on the V-CUT path is milled and the blind groove is formed, the problem of green oil dropping during the V-CUT is solved, and a better appearance and performance is achieved.

AI Technical Summary
Technical Problem
In the PCB processing of ceramic filler plates, the direct use of the V-CUT method will cause the plate surface to lose oil and affect the appearance and performance.
Method used
Before the V-CUT step, mill the green oil on the V-CUT path on both sides of the plate by controlling deep milling to form a blind groove, and perform V-CUT in the blind groove to avoid oil loss.
Benefits of technology
It effectively prevents the green oil from falling off when the V-CUT, maintains the appearance and performance of the PCB, and meets the requirements of V-CUT bridged for plates printed with green oil.

Abstract
The invention discloses a processing method for improving V-CUT resistance welding falling, relates to the technical field of PCB processing, and can prevent green oil falling during V-CUT of ceramic filling type plates. And processing data: compiling a V-CUT process flow file, and setting the cutting depth, the cutting speed and the cutter type of the V-CUT process. And depth-controlled milling of the blind groove: performing depth-controlled milling on the PCB by the numerical control milling machine, and processing the blind groove on the PCB. V-CUT, wherein V-shaped grooves are formed in the two sides of the PCB through V-CUT equipment or a cutting machine; and edge milling: processing the edge of the PCB through a milling machine, adjusting the size of the PCB, and removing burrs on the edge of the PCB. Before V-CUT, a green oil layer and a part of a base material layer on the surface of a single board are milled off through depth control, and then a V-CUT groove is formed, so that oil is prevented from falling during V-CUT, the appearance meets the processing requirement, and the requirement that V-CUT bridging is adopted for such boards printed with green oil is met.
