NPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-2C for MSL classification at lead-free peak reflow temperature. NPEC defines Green to mean lead-free (RoHS compliant) and halogen free (Br or Cl does not exceed 9ppm by weight in homogeneous material and total of Br and Cl does not exceed 15ppm by weight). NPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders. 1
