Abstract: A method for manufacturing a non-planar printed circuit board assembly (1) is disclosed. The method comprises providing a planar formable substrate (2) for supporting a conductive material (3) and at least one electronic component (4), printing a circuit pattern of an uncured conductive material (3) on the planar substrate (2), forming the substrate (2) and the uncured conductive material (3) into a non-planar shape, and curing the conductive material (3), wherein the substrate (2) comprises a metal sheet and an electrically insulating coating (2b) arranged between the metal sheet and the conductive material (3).

Abstract: A method for fabricating an LED/phosphor structure is described where an array of blue light emitting diode (LED) dies are mounted on a submount wafer. A phosphor powder is mixed with an organic polymer binder, such as an acrylate or nitrocellulose. The liquid or paste mixture is then deposited over the LED dies or other substrate as a substantially uniform layer. The organic binder is then removed by being burned away in air, or being subject to an O2 plasma process, or dissolved, leaving a porous layer of phosphor grains sintered together. The porous phosphor layer is impregnated with a sol-gel (e.g., a sol-gel of TEOS or MTMS) or liquid glass (e.g., sodium silicate or potassium silicate), also known as water glass, which saturates the porous structure. The structure is then heated to cure the inorganic glass binder, leaving a robust glass binder that resists yellowing, among other desirable properties.
