Systems and method for providing a micro-channel array are provided. In some embodiments, a micro-channel array includes a plurality of micro-channels having a first end and a second end; where at least one of the first end and the second end allows fluid connectivity between the plurality of micro-channels. In some embodiments, the micro-channel array includes external manifolding for fluid connectivity between the plurality of micro-channels. In some embodiments, the micro-channel array includes internal manifolding for fluid connectivity between the plurality of micro-channels. This may solve one of the largest causes of low yields and poor performance consistency in the production process while at the same time simplifying production and reducing production costs.
