The top and bottom side of the board uses heavy 8oz. copper to help dissipate heat better. It also has a 3mm diameter solid copper inlay directly under the SiC MOSEFTs (Q1 and Q2) to effectively transfer the heat to the bottom side of the board. The board is mechanically attached via 5 nonconductive screws to an extruded aluminum heatsink with an integrated 30mm fan.

Connectors CAUTION THERE CAN BE VERY HIGH VOLTAGES PRESENT ON THIS BOARD WHEN CONNECTED TO AN ELECTRICAL SOURCE, AND SOME COMPONENTS ON THIS BOARD CAN REACH TEMPERATURES ABOVE 50° CELSIUS. FURTHER, THESE CONDITIONS WILL CONTINUE AFTER THE ELECTRCIAL SOURCE IS DISCONNECTED UNTIL THE BULK CAPACITORS ARE FUL LY DISCHARGED. DO NOT TOUCH THE BOARD WHEN IT IS ENERGIZED AND ALLOW THE BULK CAPACITORS TO COMPLETELY DISCHARGE PRIOR TO HANDLING THE BOARD. The connectors on the board have very high voltage levels present when the board is connected to an electrical s ource, and thereafter until the bulk capacitors are fully discharged. Please ensure that appropriate safety procedures are followed when working with these connectors as serious injury, including death by electrocution or serious injury by electrical shoc k or electrical burns, can occur if you do not follow proper safety precautions. When devices are being attached for testing, the board must be disconnected from the electrical source and all bulk capacitors must be fully discharged. After use the board should immediately be disconnected from the electrical source. After disconnection any stored up charge in the bulk capacitors will continue to charge the connectors. Therefore, you must always ensure that all bulk capacitors have completely discharged prior to handling the board. 警告 接通电源后，该评估板上可能存在非常高的电压，板子上一些组件的温度可能超过50摄氏 度。此外，移除电源后，上述情况可能会短暂持续，直至大容量电容器完全释放电量。通 电时禁止触摸板子，应在大容量电容器完全释放电量后，再触摸板子。 板子上的连接器在充电时以及充电后都具有非常高的电压，直至大容量电容器完全释放电 量。请确保在操作板子时已经遵守了正确的安全流程，否则可能会造成严重伤害，包括触 电死亡、电击伤害或电灼伤。连接器件进行测试时，必须切断板子电源，且大容量电容器 必须释放了所有电量。使用后应立即切断板子电源。切断电源后，大容量电容器中存储的 电量会继续输入至连接器中。因此，必须始终在操作板子前，确保大容量电容器已完全释 放电量。

When the board is connected to an electrical source and for a short time thereafter until board components are fully discharged, some board components will be electrically charged and/or have temperatures greater than 50˚ Celsius. These components may include bulk cap acitors, connectors, linear regulators, switching transistors, heatsinks, resistors and SiC diodes that can be identified using a board schematic. Users should contact Cree at sic_powr@cree.com for assistance if a bo ard schematic is not included in the Documentation or if users have questions about a board’s components. When operating the board, users should be aware that these components will be hot and could electrocute or electrically shock the user. As with all electronic evaluation tools, only qualified personnel knowledgeable in handling electronic performance evaluation, measurement, and diagnostic tools should use the board. User Responsibility for Safe Handling and Compliance with Laws Users should read th e Documentation and, specifically, the various hazard descriptions and warnings contained in the Documentation , prior to handling the board. The Documentation contains important safety information about voltages and temperatures. Users assume all responsibility and liability for the proper and safe handling of the board. Users are responsible for complying with all safety laws, rules, and regulations related to the use of the board. Users are responsible for (1) establishing protections and safeguards to ensure that a user’s use of the board will not result in any property damage, injury, or death, even if the board should fail to perform as described, intended, or expected, and (2) ensuring the safety of any activities to be conducted by the user or the user’s employees, affiliates, contractors, representatives, agents, or designees in the use of the board. User questions regarding the safe usage of the board should be directed to Cree at sic_power@cree.com. In addition, users are responsible for:

• compliance with all international, national, state, and local laws, rules, and regulations that apply to the handling or use of the board by a user or the user’s employees, affiliates, contractors, representatives, agents, or designees.
• taking necessary measures, at the user’s expense, to correct radio interference in the event that operation of the board causes interference with radio communications. The board may generate, use, and /or radiate ra dio frequency energy , but it has not been tested for compliance within the limits of computing devices pursuant to Federal Communications
