6.2 Due to variances in equipment, solder pastes and applications (board design, component density, etc.), Samtec

does not specify a recommended reflow profile for our connectors. The processing parameters provided by the

solder paste manufacturer should be employed and can usually be found on their website.

All of Samtec

’s surface mount components are lead free reflow compatible and compliant with the profile

parameters detailed in IPC/JEDEC J-STD-020E which requires that components be capable of withstanding a peak

temperature of 260°C as well as 30 seconds above 255°C.

6.2.1

These guidelines should not be considered design requirements for all applications.

Samtec recommends testing interconnects on your boards in your process to guarantee optimum results.

6.3 Maximum Reflow Passes: The parts can withstand three reflow passes at a maximum component temperature of

260°C.
