Hello Technetters,

We are designing a Printed Board Assembly that will be required to operate
in an ambient temperature up to 100 degrees Centigrade.
There have been concerns expressed about the strength of solder joints at
that temperature.
Could anyone share any of their experiences using conventional solders and
FR4 materials for similar applications.
(this is not aerospace stuff, just gets very hot when it is working in a
warm location.)
Would standard solder pastes be satisfactory for this application, or are
there any suggestions for the use of a higher temperature solder. Also,
would the high temp solders present a problem for the assembly shops?

regards,

Phil.
