J-standard soldering refers to IPC J-STD-001C, the only remaining industry standard for soldering. Previously the Department of Defense had a standard called MIL-STD-2000, but that has been canceled.
Founded in 1957 as the Institute for Printed Circuits, it became known as IPC in 1999 after some confusing name changes. IPC now complements its name with "Association Connecting Electronics Industries" to reflect its mission statement.
IPC dedicates its efforts to establishing international standards that guarantee quality electronic circuits that comply with government regulations. It also promotes financial success of its member companies.

Several electronics schools and institutes teach J-standard soldering in a practical, hands-on setting. Many of them include a copy of IPC J-STD-001C in the price of their tuition.
