6 / 8 page Product Specification Series: QSE / QTE 0,80 mm (.0315”) Q Strip ® High Speed Ground Plane Socket / Terminal Strips Revision: C Date: November 11, 2015 © Samtec, Inc. Page 6 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 and/or offset center of gravity, right angle (-RA) components cannot be run through the reflow oven while inverted. Samtec Recommended Temperature Profile Ranges (SMT) Sn-Pb Eutectic Assembly Preheat/Soak (100°C-150°C) Max Ramp Up Rate Reflow Time (above 183°C) Peak Temp Time within 5°C of 235°C Max Ramp Down Rate Time 25°C to Peak Temp 60-120 sec. 3°C/s max. 40-150 sec. 235°C 20 sec. max. 6°C/s max. 6 min. max. Pb-Free Assembly Preheat/Soak (150°C-200°C) Max Ramp Up Rate Reflow Time (above 217°C) Peak Temp Time within 5°C of 260°C Max Ramp Down Rate Time 25°C to Peak Temp 60-120 sec. 3°C/s max. 40-150 sec. 260°C 30 sec. max. 6°C/s max. 8 min. max. 7.3.1 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. 7.4 Maximum Reflow Passes: Parts can withstand three reflow passes at a peak component temperature of 260°C. |
