Having been in the machining industry for many years, you must be no stranger to tool failure.
Flank wear
Flank wear refers to the abrasion loss of the flank of the tool immediately below the cutting edge. The carbide particles in the workpiece material or the work-hardened material rubs against the blade. Small pieces of the coating peel off and the blade rubs. The cobalt element in the blade is finally separated from the crystal lattice, reducing the adhesion of the cemented carbide and thus peeling off.
Crumble
Flank chipping
Rake area edge
Certain workpiece materials may create a rake area between the chip and the cutting edge. When the continuous lamination of the workpiece material is connected to the cutting edge, built-up edge will occur. The built-up tumor is a dynamic structure. During the cutting process, the cut surface of the built-up edge continuously peeled off and reattached.
Evaluation of circuit board quality and process improvement requires slicing as a basis for objective inspection and judgment. Slice analysis using metallographic equipment is an important means to check the thickness of PCB/PCBA internal circuits, number of layers, through hole aperture size, through hole quality observation, PCB/PCBA solder joint cavity, interface bonding status, and wetting quality evaluation.
