Abstract:
A composite standoff is formed on a circuit board during the processing of the circuit board while an array of electrical circuit traces including contact pads are formed, portions of the electrical circuit traces are covered by a solder mask, and legend ink is applied to the circuit board for locating electronic components on the circuit board without any need for an additional step.
Abstract:
Surface mounting of components includes providing a substrate (10) that has a first surface and a second surface. A portion of the first surface is coupled to a conductive layer (20) that is patterned. A compliant layer (50) is introduced to the first surface of the substrate (10) and to the conductive layer (20). At least one aperture is formed in the compliant layer (50) which extends to the surface of the conductive layer (20). Conductive material is introduced into the aperture(s). Solder couples the surface mount component (90) to the compliant layer (50).
