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.

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.
