    摘要： A transfer fluxing apparatus is provided. The apparatus is a flux reservoir for holding flux, a compliant pad attached to an opening in the flux reservoir and a means for controlling deposition of flux onto the compliant pad. The apparatus can be attached to an automated component placement machine. In the preferred embodiment of the invention, the control means is a valve located within the flux reservoir. The valve is opened by applying pressure to a plunger that extends through the compliant pad. When the plunger is pressed, the valve opens, and flux falls onto the compliant pad. Flux then passes through the pad to a component placement site. A method for automated fluxing and to component placement also is provided.

    摘要： A method and device for attaching a module having a ball grid array or column grid array of solder material thereon arranged in a given pattern or footprint to a substrate having an array of connector pads arranged in the same pattern is provided. A preformed alignment device has an array of through holes therein aligned in the same pattern or footprint as the ball grid array or column pattern on the module and the pattern of contact pads on the substrate. The through holes in the preform are filled with a solder material which can be either a solder paste or a solid solder or with a curable conductive adhesive. The solder preferably is a lead-tin eutectic, but in any event has a melting point of less than about 240.degree. C. and in the case of the conduction adhesive, will cure below about 240.degree. C. In the case of solid solder, thin films of flux material can be applied to opposite faces of the preform to prevent the solder from dislodging therefrom and to act as a flux when the solder is reflowed.

    摘要： A method and device for attaching a module having a ball grid array or column grid array of solder material thereon arranged in a given pattern or footprint to a substrate having an array of connector pads arranged in the same pattern is provided. A preformed alignment device has an array of through holes therein aligned in the same pattern or footprint as the ball grid array or column pattern on the module and the pattern of contact pads on the substrate. The through holes in the preform are filled with a solder material which can be either a solder paste or a solid solder or with a curable conductive adhesive. The solder preferably is a lead-tin eutectic, but in any event has a melting point of less than about 240° C. and in the case of the conduction adhesive, will cure below about 240° C. The preform with the filled through holes is interposed between the module and the substrate with the material in the holes in contact with the solder balls or columns and the contact pads. Heat is applied to reflow the solder or cure the adhesive in the holes to join the module to the substrate. Depending upon the composition of the solder of the balls or columns, they might or might not melt. In the case of solid solder, thin films of flux material can be applied to opposite faces of the preform to prevent the solder from dislodging therefrom and to act as a flux when the solder is reflowed.
