Abstract

In an effort to remain competitive in a cost driven global market, electronic equipment manufacturers have become increasingly dependent on hard automa- tion and programmable robots for the placement of leaded as well as surface mounted components. The positional tolerances inherent in the assembly process forces the designer to specify a PCB through-plated hole size which is larger than desired from a solder joint strength standpoint. The invention described herein provides a method to allow for the positional tolerances of the assembly process and still provide a solder joint which is resistant to fracturing.
