IPC J-STD-609B:2016 PDF Download

IPC J-STD-609B:2016 is a standard that provides guidelines for the marking and labeling of components, PCBs (Printed Circuit Boards), and PCBAs (Printed Circuit Board Assemblies) to identify various attributes. These attributes include whether the assembly is assembled using lead-containing or lead-free solder, the type of interconnect terminal finishes and materials used in the components, the maximum temperature that the components can withstand during assembly or rework processing, the base materials used in PCB construction (including the use of halogen-free resin), the surface finish of PCBs, and the conformal coating on PCBAs.

The purpose of this standard is to facilitate the assembly, rework, repair, and recycling processes by providing clear and consistent identification of these attributes. This ensures that the correct soldering materials and processes are used, prevents components from exceeding their maximum temperature limits, and enables proper handling and disposal of PCB materials.
