Lawsuit about inadequate soldering

Postby Ramon » Wed Apr 12, 2017 8:01 am

It is often stated, IPC standards do not have a large juridical impact. But neglecting assembly procedures is a good way to see a lawsuit being filed against a manufacturer.
In this case a well-known brand of mobile phones sees a class-action lawsuit being filed against them.

The imputation in the lawsuit is following:
"At the time of manufacture, the phone's processor was inadequately soldered to the circuit board. As a result, the solder bumps connecting the processor to the circuit board are unable to withstand the heat—and the cycles of thermal expansion and contraction—created by the processor’s routine operation. The bumps consequently crack and fail. As the solder bumps connecting the phone's processor to the circuit board begin to crack and fail, the device manifests symptoms of impending failure by freezing and becoming temporarily non-functional, suffering performance slowdowns, overheating, and/or rebooting at random. Eventually, after these warning signs, the phone fails entirely, through an endless reboot cycle." (* brand/type exempt)

So this manufacturer assembled BGA soc's on the mainboard with an unsatisfactory process and fialed to test for these issues.
Prosecutors now demand repair and compensation. Where mutliple tenthousands of phone's are affected, this can bring even large companies onto it's knees.

IPC standards like J-STD-001 and IPC-7095 would have provided guidance to the assembly process and consecutive reliability testing.
Keep calm and focus on soldering

Thank you so much, this is a very useful information. I am glad that I am a member of this forum and learning so many things every day.

"Prosecutors now demand repair and compensation" these rules are fair enough because now no one can do fraud to anyone.
