37、 16602-70-10:2015EN 16602-70-10:2015 (E) 8 1 Scope This Standard defines the requirements for evaluation, qualification and maintenance of qualification of PCB manufacturers for different types of PCBs. This Standard is applicable to the following type of PCBs: Rigid PCBs (single-sided, double-sided

38、, multilayer, sequential-laminated multilayer, metal core) Flexible PCB (single-sided and double-sided) Rigid-flex PCBs (multilayer and sequential-laminated multilayer) High frequency PCBs Special PCBs. PCBs are used for the mounting of components in order to produce PCB assemblies performing comple

39、x electrical functions. The PCBs are subjected to thermal and mechanical shocks during their assembly such as mounting of components by soldering, rework and repair under normal terrestrial conditions, and in addition the complex PCB assembly are subjected to the environment imposed by launch and sp

40、ace flights. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.
