Abstract
A method of applying a coating to a device which has one or more components housed in a housing. A liquid coating precursor is applied to at least part of the internal surface of the housing and/or at least part of the one or more components within the housing. Low pressure conditions are applied to the closed housing, sufficient to cause the liquid coating precursor to evaporate and initiation of the liquid coating precursor to thereby cause the coating to form on at least some of the internal surfaces of the device.
Claims23
A method of applying a coating to an electronic or electrical device, the method comprising the steps of:
- (i) providing an electronic or electrical device comprising one or more components housed in a housing of the electronic or electrical device;
- (ii) applying liquid coating precursor to at least part of the internal surface of the housing and/or at least part of the one or more components while the housing is open or closed;
- (iii) closing the housing if the liquid coating precursor is applied while the housing is open in step (ii);
- (iv) evaporating the liquid coating precursor applied in step (ii) by applying below atmosphere pressure conditions to the closed housing, with the one or more components inside the closed housing of the electronic or electrical device in a processing chamber;
- and
- (v) initiation of the evaporated coating precursor, to thereby cause the coating to form from the coating precursor on at least some of the internal surfaces of the electronic or electrical device.
