A. All RoHS compliant (Pb-free) products are backwards compatible and qualified for a lower temperature (220C to 240C) Pb process and solder. CML can provide solderability test results if required by the customer. CML can confirm that RoHS compliant devices can and have been successfully soldered with Pb- based solders. Pure matte Sn has been chosen by CML due to its history of reliable perfomance in Sn-Pb soldering processes and its compatibility with Pb-free soldering. CML has carried out research to determine that its Pb-free devices perform at standard Sn-Pb reflow temperatures.
