Currently, our design group is considering using SMT parts for
assembly onto an FR4 pcb [one or both sides] with dimensions:
approx 22" x 3". We are confronted with the question as to whether we
can do this reliably since this flat substrate/SMT parts mounted will be
formed [bent] into an arch with a radius of curvature of 36" in the final assembled
product.
The concern is stress on solder joints even though it is a relatively
small arch. At this point, we only anticipate using 44 pin plcc [50 mil] and
discrete smt r's and c's. If particular packages should or should not be used we
would like to know .
Can anyone recommend an alternative or a source of information regarding the
feasibility of doing this. It would be appreciated. Thanks
