Took apart a Volvo 850 fuel pump relay. Cracks everywhere.


Some of the responses to your post are misleading. The dull, grainy look is
normal with lead-free solder.

The cracks are not necessarily a fault. Surface cracks that we can see,
often do not extend deep enough to cause problems.

In any case, soldered joints have indeed been compromised by the new
"improved" lead-free alloys!

Mixing politics and engineering will almost always yield bad decisions.
