Etching Factor at Phillip Amber blog

Etching Factor. A pcb’s etch factor results from the board fabrication process that produces the copper features. Just as the tolerance band and minimum feature sizes in photo etching are driven by metal thickness, so too is the etch factor. The cse process is characterized by a. It helps the designers and. This is called undercut, when you divide the thickness of the base copper by the amount of undercut you get a value known as the etch factor (d/c in the figure below). The significance of this is that. It’s the average overhang of resist after top width reduction. Pcb etch factor or etch compensation is an etching process modification used by the pcb manufacturers to decide the extent and accuracy of etching. From the parameters in figure 3, there are two descriptive measures of the etching process: The best etch factor with a pcb etchant is the 4:1 ratio you get from maintaining alkaline cupric chloride in its top condition. To rapidly process boards with dense, intricate copper designs, manufacturers use an applied layer of etch resist that protects the desired copper while introducing an etchant bath to remove the unprotected copper. (controlled surface etching) process is capable of making finer line/space circuits like around 25/25 microns.
