The PCB etch factor relates the width of the trace (at the top base, where it’s easily measured) to the depth of etching penetration.

Medical device contract manufacturing is becoming more commonplace as market forces dictate shorter production cycles without sacrificing quality.

PCB ground planes are usually one or more metal layers within the layer stackup of the circuit board, or in some cases, areas of metal on the external board layers. These layers are referred to by several names, including area fills, copper pours, and negative planes in addition to the standard “ground plane.” Not only do they supply the zero-reference voltage for the circuit board, but they also provide signal return paths for most of the circuitry in the design. That’s just the beginning, though, as there’s a lot more to understanding ground planes in PCB design yet to come.

We will be looking at PCB mouse bites dimensions to give you a better understanding of how circuit boards are manufactured.

Here’s a closer look at the IPC assembly standards your CM should be using to build your circuit board, and how the best CMs incorporate those standards into all aspects of their operations.

PCB etching is the process of creating the conductive features of the board from the copper-clad laminate used in the board’s construction.
