Surface Mount Information
Pick and Place
The SLIN-20F1Ax modules use an open frame construction and are designed for a fully automated assembly
process. The modules are fitted with a label designed to provide a large surface area for pick and place
operations. The label meets all the requirements for surface mount processing, as well as safety standards, and
is able to withstand reflow temperatures of up to 300
Nozzle Recommendations
The module weight has been kept to a minimum by using open frame construction. Variables such as nozzle
size, tip style, vacuum pressure and placement speed should be considered to optimize this process. The
minimum recommended inside nozzle diameter for reliable operation is 3mm. The maximum nozzle outer
diameter, which will safely fit within the allowable component spacing, is 7 mm.
Lead Free Soldering
The SLIN-20F1Ax modules are lead-free (Pb-free) and RoHS compliant and are both forward and backward
compatible in a Pb-free and a SnPb soldering process. Failure to observe the instructions may result in the
failure of or cause damage to the modules and can adversely affect long-term reliability.
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. C (Moisture/Reflow Sensitivity Classification for Nonhermetic
Solid State Surface Mount Devices) for both Pb-free solder profiles and MSL classification procedures. This
standard provides a recommended forced-air-convection reflow profile based on the volume and thickness of the
package. The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using
Sn/Ag/Cu solder is shown below.
MSL Rating
The SLIN-20F1Ax modules have a MSL rating of 2.
