1. MICROMEGAS CONNECTICS Electronics Boards And Readout Panels 25 JUNE 2013

2. MICROMEGAS Contributors Hans Danielsson Jordan Degrange Francisco Perez Gomez Givi Sekhniaidze Joerg Wotschack

3. MICROMEGAS Main Goal Connect Electronics Boards to Readout Panels. Challenge 512 channels on a 220mm wide PCB Test Zebra® Connector. Elastrometric connector, with fine metal conductive element and Silicone insulation.

4. MICROMEGAS Connector must be compressed …

5. MICROMEGAS … So, specific profile has been designed. Readout panel Spacer Drift Electrode Panel Electonic Board Profile ZEBRA

6. MICROMEGAS Due to thin pitch, electronic boards must be well aligned (±0.2) above Readout Panels ! PCB Readout Panel A guide was positionned at both sides to make the insertion easier.

7. MICROMEGAS Samtec connectors, 3 utilities: 1.Ground connection 2.Guarantee alignment between PCB & Readout P. 3.Lock pcb in position (Keep ZEBRA compressed)

8. MICROMEGAS Process: Step 1: Step 2: PCB insertion Step 3:Step 4: Plugged SAMTEC connector ZEBRA® Connector compressed

9. MICROMEGAS First Prototype:

10. Conclusion: MICROMEGAS VALIDATED

11. Futur: 1.Improve Alignement Replace the 2 circular pins by straight guides. 2.Improve Accuracy of height Replace square profil and machined part by a specific aluminium profile. 3.Improve connector attachment Solder 5 Samtec connectors on aluminium bar. MICROMEGAS
