    摘要: Provided is a manufacturing process for electronic circuit components such as bare dies, and packaged integrated chips, among other configurations, to form electronic assemblies. The surface of the electronic circuit component carries electronic elements such as conductive traces and/or other configurations including contact pads. A method for forming an electronic assembly includes providing a tacky layer (302A). Then an electronic circuit component (304A) is provided having a first side and a second side, where the first side carries the electronic elements. The first side of the electronic circuit component (304A) is positioned into contact with the tacky layer (302A). A bonding material (306A) is then deposited to a portion of the adhesive layer (302A) that is not covered by the first side of the electronic circuit component (304A), to a depth which is sufficient to cover at least a portion of the electronic circuit component (304A). The bonding material (306A) is then fixed or cured into a fixed or cured bonding material, and the tacky layer (302A) is removed. By these operations, the electronic circuit component is held in a secure attachment by the fixed or cured bonding material (306A), and circuit connections (308B) may be made.

    摘要: Provided is a manufacturing process for electronic circuit components such as bare dies, and packaged integrated chips, among others, where the surface of the electronic circuit component is at the same level as the associated substrate, the surface of the electronic circuit component holding connection pads. A gap exists between the electronic circuit component, and the end of an opening within the substrate. This gap is filled with a filler material, such as a bonding material. The bonding material also used to encapsulate or bond together the back side of the substrate and electronic circuit component. During the manufacturing process, the front surface of the electronic circuit component (which includes the contact pads) and the front surface of the substrate which includes electronic circuitry are held in an adhesive relationship by a flat material having an upper surface which includes adhesive or sticky material (such as PDMS). Once the flat material is removed the planar flat or level upper surface can readily accept the formation of conductive traces by the use of inkjet printing or other technologies.
