System, Apparatus and Method for Utilizing Surface Mount Technology on Metal Substrates
A method for forming a circuit pattern on an integrated substrate structure includes providing an insulating surface which includes a pattern forming portion. An activation ink is deposited only on the pattern forming portion to form a non-conductive isolation layer. A first metal layer is formed on the non-conductive isolation layer by electroless plating. A patterned portion of the first metal layer is isolated from a remaining portion of the first metal layer to form the circuit pattern. A non-conductive masking layer is applied on the first metal layer. A second metal layer is formed on the non-conductive masking layer. A surface mount land pattern and pad configuration is determined. A solder mask layer is applied to the patterned portion. A protective layer is applied to protect pad areas not covered by the solder mask layer. An electrical component may then be mounted to the pad(s).
PHOTOCURABLE COMPOSITION HAVING LOW SHRINKAGE AFTER CURING
A photocurable composition can comprise a polymerizable material and a shrinkage compensating agent (SCA), wherein the photocurable composition may be adapted that a linear shrinkage of the photocurable composition after curing is not greater than 3 percent. The shrinkage compensating agent can be a compound comprising a functional group which releases a gas if subjected to UV radiation or heat. The released gas can form a fine pore structure within the cured photocurable composition and may thereby compensate shrinkage of the photocurable composition during curing.

A method for producing an electrically conductive thin film on a substrate is disclosed. Initially, a reducible metal compound and a reducing agent are dispersed in a liquid. The dispersion is then deposited on a substrate as a thin film. The thin film along with the substrate is subsequently exposed to a pulsed electromagnetic emission to chemically react with the reducible metal compound and the reducing agent such that the thin film becomes electrically conductive.
