A method of forming a braze join between two components is disclosed, in which braze material is introduced into a gap between the two components by capillary action. This assists in reducing flooding. Also disclosed is a component for use with the method, and an assembly produced by the method. In one form, the component comprises a recess or reservoir for storing braze material, in fluid communication with an aperture to allow the braze material to be drawn into the gap by capillary forces. The method may be used in a number of applications including medical devices and more specifically, a cochlear implant.

1. A method of joining a first component and a second component together to form an assembly by brazing, the method comprising: placing a surface of the first component proximate to a surface of the second component to form a gap therebetween;introducing a liquid braze material into the gap from at least one of the surface of the first component or the surface of the second component such that the braze material is drawn into the gap by capillary action; andplacing a supply of braze material into a recess of at least one of the first and second components, the recess being in fluid communication with a plurality of apertures in the at least one surface. 2. The method as claimed in claim 1, wherein the step of introducing the braze material into the gap further comprises heating the assembly to a temperature at or greater than a melting point of the braze material, and less than a melting point of the first and second component, and drawing at least some of the liquid braze material from the recess through the plurality of apertures and into the gap by capillary action. 3. The method as claimed in claim 2, wherein the method further comprises the step of placing the supply of braze material into the recess prior to placing the surface of the first component proximate to the surface of the second component to form the gap therebetween. 4. The method as claimed in claim 1, wherein the braze material is confined within the assembly when in the liquid form. 5. The method of claim 1, the method further comprising: allowing the liquid braze material to solidify such that a capillary meniscus extends from the surface of the first component to the surface of the second component. 6. The method of claim 1, wherein: the first component is a flange of a medical device implant and the second component is a feedthrough of a medical device implant. 7. The assembly as claimed in claim 6, wherein the medical device implant is a cochlear implant. 8. The method of claim 6, wherein the feedthrough is a connection providing electrical connectivity from inside to outside of a hermetic enclosure of a cochlear implant. 9. The method of claim 6, wherein the recess is at least partially formed by a secondary collar adjacent the flange or the feedthrough. 10. The method of claim 1, wherein the gap is about 3-150 microns in width. 11. The method of claim 1, wherein the aperture is located substantially in the middle of the surface. 12. The method of claim 1, wherein the plurality of apertures comprise at least one hole. 13. The method of claim 1, wherein the plurality of apertures comprise at least one slot. 14. The method of claim 1, wherein one of the first component and the second component is titanium, the other of the first component and the second component is aluminum, and the braze material is an alloy of titanium, copper and nickel. 15. A method of joining a first component and a second component together to form an assembly by brazing, the method comprising: placing a surface of the first component proximate to a surface of the second component to form a gap therebetween;introducing a liquid braze material into the gap from at least one of the surface of the first component or the surface of the second component such that the braze material is drawn into the gap by capillary action; andplacing a supply of braze material into a recess of at least one of the first and second components, the recess being in fluid communication with an aperture in the at least one surface,wherein the recess is at least partially formed by a secondary collar adjacent the first component or the second component. 16. The method as claimed in claim 15, wherein the step of introducing the braze material into the gap further comprises heating the assembly to a temperature at or greater than a melting point of the braze material, and less than a melting point of the first and second component, and drawing at least some of the liquid braze material from the recess through the aperture and into the gap by capillary action. 17. The method as claimed in claim 16, wherein the method further comprises the step of placing the supply of braze material into the recess prior to placing the surface of the first component proximate to the surface of the second component to form the gap therebetween. 18. The method as claimed in claim 15, wherein the braze material is confined within the assembly when in the liquid form. 19. The method of claim 15, the method further comprising: allowing the liquid braze material to solidify such that a capillary meniscus extends from the surface of the first component to the surface of the second component. 20. The method of claim 15, wherein: the first component is a flange of a medical device implant and the second component is a feedthrough of a medical device implant. 21. The assembly as claimed in claim 20, wherein the medical device implant is a cochlear implant. 22. The method of claim 20, wherein the feedthrough is a connection providing electrical connectivity from inside to outside of a hermetic enclosure of a cochlear implant. 23. The method of claim 15, wherein the gap is about 3-150 microns in width. 24. The method of claim 15, wherein the aperture is located substantially in the middle of the surface. 25. The method of claim 15, wherein the recess is in communication with a plurality of apertures. 26. The method of claim 15, wherein the aperture comprises a hole. 27. The method of claim 15, wherein the aperture comprises a slot. 28. The method of claim 15, wherein one of the first component and the second component is titanium, the other of the first component and the second component is aluminum, and the braze material is an alloy of titanium, copper and nickel.
