Motor drive PCB layout must provide a short high-frequency connection between the local DC-link capacitance and the switching power stage. Motor phase current alone does not describe that connection. During a switching transition, current transfers between semiconductor paths while the inductive l...
1. IPC Class 2 vs Class 3: When Is Class 2 Enough?Choosing between IPC Class 2 and IPC Class 3 starts with the consequences of a potential failure. IPC Class 2 is used for products that need dependable performance and a long service life, but can tolerate a service interruption. While for IPC ...
Thermal via resistance can be estimated from the copper in the via barrel. The first calculation uses the copper cross-section, the board thickness, and an assumed copper conductivity. It gives an ideal one-dimensional resistance for the barrel alone. It does not give junction-to-ambient resistanc...
