1. Etienne CARLIER TE-MPE-EM Support Feedback from TE/ABT

2. What is Functioning Well In general, good and very useful service Thanks from TE/ABT to all the persons concerned for their continuous support to our different projects

3. Schematics – Missing “macro components” that can be reused in different project (i.e. FPGA/CPLD powering circuit). – Components library is OK. Some issues with identification of powering pins in multi parts digital circuits. – Creation of new symbol works fine… but not error free (discovered only once the prototype is produced). Need for quality check done on each component created Routing – Establishment of a clear “cahier des charges” between designer and developer missing at the beginning of the routing process (PCB design constraints). – Project tracking during routing is perhaps not optimum. Creation of a wiki page for each project can perhaps help. – Manual cross-check of result provided by auto-router Mechanics (front-panel) – Support of CATIA drawing still missing What Would Need Improvement

4. Numbering – Not unique (EDA, AED, old PS numbering convention… ) – EDA numbering reserved only to design fully handled by TE/MPE/EM – AED numbering (same structure as EDA) not supported by TE/MPE/EM – Some improvement welcome in order to obtain a unique numbering scheme (and production folder) for all electronics design Production (prototype and small series) – Done at via TE/MPE/EM or directly with external firms – Acceptance of production done via TE/MPE/EM can be an issue (quality control). Where is the responsibility. Mainly true when production include a high degree of manual actions (cabling) Possibility to produce special multi-layers PCB – With different copper layers thickness (power electronic) – With different dielectric layers thickness (high-voltage) – Expertise sometime missing in TE/MPE/EM What Would Need Improvement (cont.)

5. My feeling is that no “electronic design activities” should go out of CERN without approval of TE/MPE/EM… at least for prototyping and small series – Activity code in DAI with mandatory approval from TE/MPE/EM – Electronic design review by “TE Electronic Coordinator” TE/MPE/EM should act as “link office” between CERN and External Firms (PCB routing, prototype assembly…) – Selection of external firms that can be used by clients developers according to a predefined “cahier des charges” Uniform numbering Uniform set of files to be included in the manufacturing dossier – Full quality control over the complete design and production chain Future Plans
