MPX220 CE Connector Crack Solder

MPX220

Level of Repair:

Problem

Service has detected a CE connector issue during MPX220 NPI process. Phones are being return for “No Charge” complaints. The failure occurred in the bulk solder and cold solder (under-reflow) was a small contributing factor but the failure appeared to be mechanical overstress of the connector. Deformation of one of the retention tabs indicated that a force had been applied to the front of the plastic pin assembly.

The CE connector found on the NPI failures was of Molex K08 prior to date code of 4261, which was known to have soldering issue.
