Trace and component spacing (electrical clearance) by voltage based on IPC-2221B table, IPC-9592B and other recommendations.
In addition, for the high voltage printed circuit boards (PCBs), the IPC-2221 calculator will aid you to determine the right spacing requirements between your PCB’s conductive elements quickly. This ensures that the high-voltage board you manufacture remains safe at that operating voltage. Any...
IPC-2221 establishes standards for PCB design aspects such as schematic, material selection, thermal management, DFM, DFA, DFT, and quality assurance. Some of the primary design requirements of high-voltage boards are defined in IPC-2221B. They include conductor spacing, creepage, and insulation r...
IPC-2221 A/B coupon A/B test coupon for IPC class 3 PCB testing The A/B coupon inspects both vias and component holes. The outer row is designated as test coupon A and the inner row represents coupon B. Test coupon A allows rework simulation of component holes and features large holes...
