This Standard has been cancelled and replaced by ECSS-Q-ST-70-28C (31 July 2008).
The repair and modification procedures detailed in this Standard are designed to maintain the rigorous standards set by the customer for the manufacture and assembly of space-quality printed circuit boards.
This Standard is confined to the repair and modification of single-sided, double-sided and multi-layer printed circuit board assemblies. However, rework may be necessary on defective solder joints as a consequence of the repair or modification process. Unassembled (bare) printed circuit boards are not covered by this Standard.
