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:

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
