In this presentation, we will discuss the evaluation of the performance of substrate materials and coatings to determine their suitability for operation in high temperature environments

PCB materials with Surface Insulation Resistance (SIR) test patterns were aged at 250 °C for over 2000 hours. During this test, the SIR and capacitance was monitored both along the surface and throughout the board at various locations. The effect on the ageing process on the dielectric breakdown strength of high temperature ageing on PCB materials and efficacy of protective coatings has been evaluated and is discussed. Optical inspection of micro-sections gave information regarding the oxygen permeation through the materials during the ageing process

Topics covered

Substrates materials
High temperature environments
Surface insulation & capacitor measurement
Impact of high temperature on coating materials
Microsection analysis

The webinar will run for between 45-60min with question and answer session. The webinars are limited to 100 delegates/companies. A copy of each of the slides presented and links to NPL reports will be provided after the webinar
