SNIS236 January 2024 TMP119
PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The TMP119 features internal strain tolerance that helps mitigate error resulting from strain developed in the DSBGA package from various common manufacturing areas, including but not limited to device solder, molding, under-fill, and board flex.
To demonstrate this capability, multiple TMP119 devices are soldered onto a rigid 62mil thick PCB, and tested under multiple flexing orientations, with pin 1 located both orthogonal and parallel to the applied microstrain examined during the test, measured through a strain gauge. The resultant temp error under this strain is measured against a known reference, and are recorded at increasing flex levels of the PCB. Figure 7-3 demonstrates device distribution under these microstrain conditions. Several non-strain tolerant devices were also subjected to the same test to demonstrate the difference.
