Method for stripping conformal coatings from circuit boards |
摘要 |
In preparation for removing a protective adherent covercoat from a circuit board that is to be repaired, the surface integrity of the coating is altered (for example, by making incisions therein). Subsequently, the coated circuit board is subjected to supercritical carbon dioxide in a processing chamber. Following this process, the coating is easily lifted from the board.
