Surface Roughness Chart: Understanding Surface Finishes ...

Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.

General Guidelines - Cosemi

Ball bonding requires only three axes of movement (X,Y,Z) while wedge bonding requires four axes of movement (X,Y,Z,θ). In ball bonding, only gold (Au) wire can be used while gold and aluminum (Al) wires are used commonly in wedge bonding. This is because Al wire will oxidize during the electronic flame off (EFO) process to form the ball.
