Strasbourg/Mulhouse Fast Test Box with LEDs

GOAL :

bonding test before and after (and during ?) one thermal cycle

J.P. Ernenwein (UHA), G. Gaudiot (IReS), T. Goeltzenlichter (IReS), J.M. Helleboid (IReS), C. Hoffmann (IReS)

SUMMARY :

ARC + TRHX + Peltiers cooling + LEDs SFH 4501 + Pulser 2 channels + LEDs driver card + copper box inside polyurethane + one module

Modules Test Meeting, 05/12/2001

LEDs array supports

Transport Plate

Guiding system

Copper piece for cold air forced circulation

Dry air input : used only at beginning

Peltier elements

Copper Box inside Polyurethane

Supercool DL-290 :cooling power/Peltier =100W @ ? T=40°C

Fan (1W) Hybrid (3W)Module

Leakage = 6W

Front end card

LEDs control

LEDs = SFH 4501, 950 nm, 5 mm diameter : 32/array ie 128 for 4 arrays

Distance between 2 LEDs emitting center = 4.57 mm :

pulser

LED light

10ns

Pulser 2 outputs

ARC

NI PCI I/O card for LEDs switch

Delay and different shapes

LEDs arrays in box

logic

LEDs control

Temperature/Humidity control : one TRHX system from Vienna (M. Friedl) : has a TTL output used to switch on/off Peltiers elements

Readout with ARC system on external trigger

LED selection with Labview software

Status :- LEDs arrays and control card are ready

(we have 3 setups)

- Box (mechanics) will be ready soon .

- We can give some LEDs.

- We have one ARC system.

- We have one TRHX system and Peltiers.

- Low voltage supplies are available, but for high voltage we plan to buy a Keithley one.
