Lauda RK20-KS with Ethylene Glycol (75%) + H2O (25%) running at -30ºC to cool the box at ~ -3º
Lauda RP855C with C8F18 to cool or thermal cycle the stave. Problems encountered with Lauda chillers:
Lauda RP845 break down, under repair -> Given a new and more powerful version in evaluation: RP855 -> faulty behaviour from time to time of the refrigerator…
Lauda RP855 has a pressure/suction pump (see next slide) for fluid circulation in the application. We suspect that the suction generates cavitations in the C8F18 (bubbling) -> fluid lost.
The system is now capable to run thermal cycles between ±30º on the power off modules (see slide)

Stave S4028 - Electrical TestStave S4028 - Electrical Test LOAD test completed:
Some dead pixel on the first row of several chip (see last week presentation) are not really bad - they respond to source.

S4024 - Robot UpgradeS4024 - Robot Upgrade Third production stave under loading
11 modules loaded -> completed tomorrow.
A Heidenhain Linear Encoder will be added to verify/correct the Z movement of the robot
A better visual inspection/measure digital microscope is under evaluation to improve module positioning in the garage position and to improve the Z precision of the CMM.
