HDI PCBs take a particular approach to routing interconnects through multiple layers to ensure reliability during fabrication, assembly, and operation. The critical structure that enables this is microvias, which are prone to failure if not designed properly. In this e-book, readers will receive an initial look at the reasons microvia reliability has come into the spotlight and why HDI PCB designers put reliability first when routing through microvias.
Aside from impedance and annular ring calculations, one of the other major formulas specified in the IPC 2221 standard relates temperature rise, trace width, and trace current. THere is also the IPC-2152 standard, both include this guidance on designing for thermal reliability, but which standard should we use?
Striplines provide some advantages over microstrips as they take advantage of natural shielding and coupling from nearby ground plane layers. Although they tend to experience higher losses due to total confinement in the dielectric, they can be thinner due to the high dielectric constant used in internal layers of a PCB. Use our free impedence calculator to help you determine the correct width needed to hit a target impedance.
An optoisolator is a cool electronic device that can be used to pass information between a diode without passing an electrical current. There are many great applications for these, but do you know which one is right for you?
The Properties panel provides access to the properties of documents and objects. The contents of the panel change depending on the active document or the selected object. This blog will quickly go over some of need to know options around the properties panel in the schematic document.
