LEAD-FREE HAND soldering : NEW TECHNOLOGIES FOR ENHANCING. THE WEAKEST LINK IN THE LEAD-FREE REWORK AND REPAIR. PROCESS CONTROL CHAIN. Mark Cannon ERSA GmbH. Wertheim, Germany Bob Klenke ITM Consulting Cedarburg, WI USA. Phil Zarrow ITM Consulting Durham, NH USA. ABSTRACT. With LEAD-FREE mass soldering processes approved and This paper describes a true breakthrough technology in lead- implemented, increased demand is placed on rework and free manual soldering that greatly enhances solder joint repair as a significant challenge that needs to be addressed quality, guarantees process stability and significantly lowers by board level assemblers. Long considered as the weakest operational cost. A case study will be presented that link in the LEAD-FREE process control chain, LEAD-FREE hand illustrates a design-for-experiment to quantify and insure soldering requires rigorous control of the thermal process LEAD-FREE solder joint reliability.
lead-free as compared to lead-free wave and reflow soldering. 1 Poor wetting and cold solder joints can occur when lower solder tip temperatures are used, or when flux
