7.3 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.

Due to their weight, QTH-120-07, -08 components cannot be run through the reflow oven while inverted.
