A method of making an electronic device includes forming a circuit layer on a liquid crystal polymer (LCP) substrate and having at least one solder pad. The method also includes forming an LCP solder mask having at least one aperture therein alignable with the at least one solder pad. The method further includes aligning and laminating the LCP solder mask and the LCP substrate together, then positioning solder paste in the at least one aperture. At least one circuit component may then be attached to the at least one solder pad using the solder paste.

A method of making an electronic device includes forming an electrically conductive pattern on a substrate, forming a cover layer on the substrate and the electrically conductive pattern, and forming openings in the cover layer and being aligned with the electrically conductive pattern. The method also includes positioning an IC on the cover layer so that bond pads of the IC are aligned with the openings, and heating under pressure the cover layer to both mechanically secure and electrically interconnect the IC.

A method for making a multilayer circuit board from circuit board layers, each including a dielectric layer and conductive traces thereon including a first metal. The method includes forming a through-via in a first circuit board layer, plating the through-via with the first metal, and coating a second metal onto the first metal of the first circuit board layer, the plated through-via, and the first metal. The method also includes aligning the first and second circuit board layers together so that the plated through-via of the first circuit board layer is adjacent a feature on the second circuit board layer, and heating and pressing the aligned first and second circuit board layers so as to laminate the dielectric layers together and form an intermetallic compound of the first and second metals bonding adjacent metal portions.

A method for making an electronic device includes forming an interconnect layer stack on a rigid wafer substrate having a plurality of patterned electrical conductor layers, a dielectric layer between adjacent patterned electrical conductor layers, and at least one solder pad on an uppermost patterned electrical conductor layer. An LCP solder mask having at least one aperture therein alignable with the at least one solder pad is formed. The LCP solder mask and interconnect layer stack are aligned and laminated together. Solder is positioned in the at least one aperture. At least one circuit component is attached to the at least one solder pad using the solder.

A method is for making a multilayer circuit board from circuit board layers, each including a dielectric layer and conductive traces thereon including a first metal. The method includes forming a through-via in a first circuit board layer, plating the through-via with the first metal, and coating a second metal onto the first metal of the first circuit board layer, the plated through-via, and the first metal. The method also includes aligning the first and second circuit board layers together so that the plated through-via of the first circuit board layer is adjacent a feature on the second circuit board layer, and heating and pressing the aligned first and second circuit board layers so as to laminate the dielectric layers together and form an intermetallic compound of the first and second metals bonding adjacent metal portions together.

An electronic device includes a substrate with a circuit layer thereon that has a solder pad. There is a liquid crystal polymer (LCP) solder mask on the substrate that has an aperture aligned with the solder pad. There is a fused seam between the substrate and the LCP solder mask. Solder is in the aperture, and a circuit component is electrically coupled to the solder pad via the solder. A first dielectric layer stack having a first plurality of dielectric layers is on the LCP solder mask and has an aperture aligned with the solder pad. There is a first LCP outer sealing layer on the first dielectric layer stack, and a second dielectric layer stack having a second plurality of dielectric layers on the substrate on a side thereof opposite the LCP solder mask. Further, there is a second LCP outer sealing layer on the second dielectric layer stack.
