 Considerations for integrating the ICE Platform stack in an OEM situation are detailed in the remainder of this document. Important key points include deciding on the type and quantity of daughter modules to use and how that relates to the overall power budget for both the power supply and the maximum currents that can be routed through the power bus. The mechanics of mounting the circuit boards and designing a thermal management system must also be designed. Connections for communication and I/O from the circuit boards to the integrator's system are also detailed in the document.

-Each ICE daughter module exposes analog interfaces on the side opposite to the copper heatsink tabs. Each module's circuit board may use a mixture of the connectors described in this section. Each connector and an associated part number shown below such that the OEM integrator my chose a suitable mating connector for their system.

Consult the product pages for each ICE module to determine the type, position, and function of any connectors used. See the respective product pages for each OEM board for a diagram of the positioning of any connectors.
+For all ICE daughter modules, the circuit boards are designed such that all I/O connectors will be on a single side, and the copper heatsinking tabs will be on the opposite side. The master controller (ICE-MC1) also follows this convention, with the exception being the serial port flat flex connector.

 === Flat Flex Connector (FFC) ===
 These FFC connectors ([[http://www.digikey.com/product-detail/en/SFW12R-1STE1LF/609-1900-1-ND/1003179|FCI PN: SFW12R-1STE1LF]]) are used the [[ice:quadtemp|ICE-QT1]] to bring out the thermistor and TEC drive signals. Lower pin count ones are also used on the [[ice:master|ICE-MC1]] master controller for interfacing digital communications. Standard 1.00 mm pitch FFC jumper cables can be used to connect to an FFC connector on the other end. The ICE system uses right angle, 1.00 mm pitch, bottom contact FFC connectors.

+Generally, the minimum bend radius for flat flex jumper cables is 2mm. The length of the stiffener behind the exposed contacts on the cable will determine how far out from the FFC pcb connector the first bend of the flat flex cable can occur. The clearance for this bend must be accounted for when designing an enclosure for the ICE boards. For example, with Molex brand flat flex cables, there needs to be a minimum 0.25 inch clearance from the front of the flat flex pcb connector to allow the cable to bend. Verify against the data sheet of the chosen flat flex jumper cable.
