“…It was later found that this was the result of trapped static charge changing the properties of the materials around the strips resulting in loss of isolation between components. It was also found that this type of damage could be cured with 400 nm UV light exposure or with deionizers [10] [11]. Figure 8B shows the original emissions found in red where breakdown started at −210 V , as well as post 1 hour UV treatment in yellow where breakdown now started at −790 V instead and the emissions region was much smaller.…”
