Termination of Semi-Rigid Cable Assemblies to ESA Specification ECSS-Q-ST-70-18 

E03 and E03+

This ESA-approved course will review the latest revision of the ECSS-Q-ST-70-18 standard and is followed by an open book multiple choice test. The review of the standard will give an understanding of the contents of the specification and why they are important. The test will develop your ability to navigate the standard and find the relevant information in an efficient manner.

 

The requirements in the standard are designed to ensure process consistency and acceptable workmanship standards resulting in the production of high reliability solder assembly, formation and preconditioning of semi-rigid R.F. cables. The course is based on the latest revision of Solder Assembly requirements of ECSS-Q-ST-70-18, The Preparation, Assembly and Mounting of R.F. Coaxial Cables.

 

The course also has a practical test. For inspectors the practical will be the QA inspection of others’ R.F Cables. For operators the practical will be assembling an R.F Cable in accordance with the standard. Both are 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.
