Umut Tosun, Application Technology Manager at Zestron America, explained, “The major differences between IPC class 2 and class 3 are found incomponent placementforsurface-mount components, cleanliness requirements based on residual contaminants on the assemblies, plating thicknesses as defined in plating...
The following article let readers know about the IPC Classes and the differences between Class 2 and Class 3 PCB types.
the copper plating in the barrel of the hole is missing exposing the dielectric material of the drilled hole. Class 1 allows three voids per hole in 10% of the holes (6012) or 5% of the holes (A-610). Class 2 allows 1 void in 5% of the holes. Class 3 and 3/A allows no voids...
IPC-A-610 Class 1 vs Class 2 vs Class 3 While Class 1 electronics typically encompass inexpensive and readily replaceable items, Class 2 electronics hold greater importance with a requirement for an extended life cycle, and Class 3 electronics represent mission-critical components. Whether it involv...
Class 1, 2 and 3 circuits are commonly used for remote control, signal and power limited circuits.
