    摘要: When an electronic component is mounted on a substrate, the electronic component is first placed on the substrate with a solid support interposed between the electronic component and the substrate. The solid support serves to space a terminal conductor of the electronic component from a corresponding terminal pad on the substrate. A conductive bonding material is then melted on the terminal pad. The melted conductive bonding material gets exposed to the peripheral atmosphere over a larger area. Even if a bubble is generated within the melted conductive bonding material, the bubble is allowed to easily get out of the melted conductive bonding material. Removal of the gas is promoted in the melted conductive bonding material. The solid support is subsequently melted. The electronic component is moved down toward the substrate, thereby contacting the terminal conductor with the melted conductive bonding material on the corresponding terminal pad. Removal of the gas in this manner leads to improvement in the strength of bonding between the substrate and the electronic component.

    摘要: Process for the production of a sealing and mechanical strength ring between a substrate and a chip hybridized by bumps on the substrate. The invention provides a process for producing an encapsulating ring (13) ensuring the sealing and mechanical strength of a chip (1) hybridized by bumps on a substrate (5). More particularly, contemporaneously with the production of the hybridization bumps (9) on the lower face (1a) of the chip or the substrate by a first meltable material, a sealing and mechanical strength ring is formed by depositing on the substrate or lower face of the electronic component a ring (13) of a second meltable material. The lower face of the chip then is placed on the substrate so as to produce the connections between said chip and said substrate by means of the first meltable material, and the thus formed assembly is heated to a temperature at least equal to the highest melting point of the first and second meltable materials, in order simultaneously to produce the hybridization bumps of the first material and the sealing ring of the second material. The ring is sized to have a height (h) and a width (d) in accordance with the following equation: d > 10 - 2 ⁢ D × h h - α in which &agr; is a shape coefficient factor and D is the largest dimension of the electronic component.
