Product Specification Series: LSS 0,635mm (.025”) Razor Beam™ High Speed Hermaphroditic Terminal/Socket Strip 7.2 Mating Angle Requirements: Connectors to be mated and unmated axially only. Zippering angles may damage connector and/or solder joints. 7.2.1 7.2.2 Revision: C Date: August 27, 2015 Page 6 © Samtec, Inc. Product Specification Series: LSS 0,635mm (.025”) Razor Beam™ High Speed Hermaphroditic Terminal/Socket Strip 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. 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. 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. Pb-Free Assembly 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. Revision: C Date: August 27, 2015 Page 7 © Samtec, Inc. Product Specification Series: LSS 0,635mm (.025”) Razor Beam™ High Speed Hermaphroditic Terminal/Socket Strip 7.4 Maximum Reflow Passes: The parts can withstand three reflow passes at a maximum component temperature of 260°C. 7.5 Stencil Thickness: The stencil thickness is .006” (0,15 mm). 7.6 Placement: Machine placement of the parts is recommended. 7.7 Hardware: Board-to-board standoffs are recommended to provide a robust mechanical connection. Samtec offers two different types: 7.7.1 Traditional Standoffs (SO) – Rigid design to statically support board-to-board applications. See options here: SO - Board Stacking Standoff 7.7.2 Jack Screw Standoffs (JSO) – Serve same function as traditional standoffs but unique, nested construction facilitates the mating and unmating process. This is especially helpful for multiple connector applications where the mating and unmating forces increase with the number of connectors used. See options here: JSO - Jack Screw Standoffs 7.8 Reflow Environment: Samtec recommends the use of a low level oxygen environment (typically achieved through Nitrogen gas infusion) in the reflow process to improve solderability. 7.9 Cleaning: Samtec, Inc. has verified that our connectors may be cleaned in accordance with the solvents and conditions designated in the EIA-364-11A standard. 8.0 ADDITIONAL RESOURCES 8.1 For additional mechanical testing or product information, contact our Customer Engineering Support Group at [email protected] 8.2 For additional information on high speed performance testing, contact our Signal Integrity Group at [email protected] 8.3 For additional processing information, contact our Interconnect Processing Group at [email protected] 8.4 For RoHS, REACH or other environmental compliance information, contact our Product Environmental Compliance Group at [email protected] USE OF PRODUCT SPECIFICATION SHEET This Product Specification Sheet (“PSS”) is a brief summary of information related to the Product identified.
