Crimping, Wire Wrapping and Wire Soldering to ESA Specifications ECSS-Q-ST-70-26, ECSS-Q-ST-70-30 and restricted ECSS-Q-ST-70-08

E09

This ESA-approved course will review the latest revisions of the ECSS-Q-ST-70-26, ECSS-Q-ST-70-30 and a restricted (to the wiring sections only) ECSS-Q-ST-70-08 standard and is followed by open book multiple-choice tests. The review of the standards will give an understanding of the contents of the specifications and why they are important. The test is designed to develop your ability to navigate the standards and find the relevant information in an efficient manner.

 

The requirements in the standards are designed to ensure process consistency and acceptable workmanship standards resulting in the production of “The Crimping of High-Reliability Electrical Connections" ECCS-Q-ST-70-26, "The Wire Wrapping of High-Reliability Electrical Connections", ECCS-Q-ST-70-30, plus the content of ECSS-Q-ST-70-08 that relates to soldering and wiring to connectors and terminals.

 

The course also has a practical test. For inspectors, the practical will be the QA inspection of others’ Crimping, Wiring and attachment of wires to terminals and connectors on a PCB. For operators, the practical consists of crimping wires and destructive testing, attaching wires to terminals and destructive testing and hand soldering wires to connectors and terminals on a PCB in accordance with the standard. Results are also inspected by the instructor to ensure an understanding and an acceptable level of practical skills can be demonstrated in accordance with the standard.

 

All necessary tools and equipment are supplied, although delegates are welcome to bring their own hand tools if desired.
