IPC-2152, Standard for Determining Current-Carrying Capacity in Printed Board Design, is for determining the appropriate sizes of internal and external conductors as a function of the current-carrying capacity required and acceptable conductor temperature rise. Replaces IPC-2221 conductor sizing charts. Provides guidance on how thermal conductivity, vias, power dissipation, printed board material and thickness, and the presence of copper planes factor into the relationship between current, conductor size, and temperature. Establishes general guidelines for sizing conductors and contains simple charts that show testing results for both internal and external conductors in air and vacuum environments. Appendix explains how variables impact the temperature rise of a conductor, and presents charts based on copper weights. 97 pages.
S3088-III AOI features enlarged inspectable PCB dimensions and improved camera technology. Is for economical electronics assembly inspection, from prototype to large series. Can be deployed for paste print or placement inspection. In high-resolution mode, reportedly detects defects on 01005 components. Revised PCB transport permits boards up to 20" x 20" to be inspected. Can be equipped for extreme cycle time requirements or heavier PCBs. Offers color evaluation for angled inspections. Comes with switchable resolution with the OnDemandHR function or integrated verification.

The Paste Roll Height Monitor is a productivity tool designed to eliminate defects. Uses lasers to detect solder paste; monitors height of the paste roll. Uses Instinctiv V9 for setup. Consists of two sensors that sit on either side of the squeegee blade framework support and are fully integrated into most printer software. A light curtain detects solder paste presence or absence, sending a signal to the printer. If paste crosses the light threshold and breaks the light beam, the printer reads that as a signal that paste is present and will continue to process boards as normal. If the light curtain is not disturbed, indicating a low paste height, the printer will alert the operator to add solder paste. As the paste roll starts to recede, the printer issues a warning.
