Process management for avionics. Aerospace and defence electronic systems containing lead-free solder - Ball grid array (BGA) re-ballingWhat is PD IEC TS 626474: 2018 BGA re balling about? PD IEC TS 626474 is the fourth part of the PD IEC TS 62647 series. This part of IEC 62647, which is a Technical Specification, defines the requirements for replacing solder balls on ball grid array (BGA) component packages in the context of an electronic components management plan (ECMP) for aerospace, defence, and high reliability products. Note: IEC TS 62239 1 and EIA STD 4899 describe the
