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 andSilicone insulation.
MICROMEGAS
Connector mustbe compressed …
MICROMEGAS
… So,specific profile has been designed.

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.
MICROMEGAS
Samtec connectors, 3 utilities:
1. Ground connection2. Guarantee alignment between PCB & Readout P.3. Lock pcb in position (Keep ZEBRA compressed)

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

First Prototype:
Conclusion:MICROMEGAS
VALIDATED
Futur:
1. Improve AlignementReplace the 2 circular pins by straight guides.
2. Improve Accuracy of height Replace square profil and machined partby a specific aluminium profile.
3. Improve connector attachmentSolder 5 Samtec connectors on aluminium bar.
