ABSTRACT:
An essentially fluxless solder joining process comprises a solder coating to be applied to a surface under controlled pressure conditions enabling the volume and shape of the solder to be desirably controlled. Coatings produced by essentially fluxless processes enable joining processes to be carried out in an essentially fluxless manner with highly desirable processing flexibility.
