 ===== PCB Dimensions ===== ===== PCB Dimensions =====
-All PCB's in the ICE Platform follow identical board dimensions and header/mounting hole locations. The PCB's themselves are 4 inches square and contain 4 mounting holes for 4-40 screws on each corner. The dimensions of the boards are shown in <imgref singlePCB>. All contain a power bus header on each side ([[http://cloud.samtec.com/catalog_english/ESQ_TH.PDF|Samtec PN: ESQ-106-13-T-D]]) and a digital communications bus header ([[http://cloud.samtec.com/catalog_english/ESQ_TH.PDF|Samtec PN: ESQ-104-13-T-D]]) in the middle of the PCB. These headers are 0.1 inch pitch board-to-board headers that allow interconnection between boards when stacked, as shown in the [[pcb_mechanics#PCB Stackup|next section]]. At the edge of the board there are copper tabs extending from four IC's (TO-220 package) for heatsinking. Details on proper heatsinking are described in a [[pcb_mechanics#Thermal Management|later section]]. Note that not all boards will utilize all four heatsinking positions.+All PCB's in the ICE Platform follow identical board dimensions and header/mounting hole locations.

 +Not all circuit boards will utilize all four heatsinking positions and therefore may have copper tabs in only a few positions. The four possible tab positions shown in the drawings will are fixed for every board even though a copper tab may not be utilized there.
