- | The Quad Temperature Controller Board (ICE-QT1) provides 4 independent PID temperature servo loops capable of sub-mK stability(( Sub-mK stability requires a proper thermal design and proper tuning of the temperature controller to the thermal plant. If you did not purchase the Laser Controller with a Laser Diode, please read the section on tuning the temperature controller.)). Each channel can drive either a single TEC (bipolar current output) or resistive heater (unipolar current output) and read a single 10k thermistor. | + | The Quad Temperature Controller Board (ICE-QT1) provides 4 independent PID temperature servo loops capable of sub-mK stability.((The ICE-QT1 has non-adjustable poles. |

+ | The flat flex jumper cables used to connect to the FFC connectors should be 1.00mm pitch with 12 conductors. Another FFC connector must be used on the other side to break out the connections for OEM use. It should be noted that when connecting to the other side of the FFC, all the pin definitions will be reversed (i.e. pin 1 on one side will be pin 12 on the other). | ||

+ | <WRAP center round info 60%> | ||
+ | Generally with flat flex jumper cables, the cables can be folded but the bend radius should not be less that 2mm. The clearance in front of the pcb FFC connectors must be at least 0.25 inches to allow the flat flex cable to exit and bend. The distance between the FFC connector and the first bend of the flat flex cable is determined by the length of the stiffener (or backing) on the flat flex cable. | ||
