Ohmite offers an array of thermal management products, including their FA-T220-25E TO package heat sink. Occasionally we get customers who wash the product, and then report that the paint coating on the heat sink appears damaged. Is this normal? Does the paint have any impact on the product? If so, is the product washable?
Ohmite does not recommend washing this product. The exterior paint does indeed assist the product with its function to a degree and is not intended for wash processes. The product is not necessarily rendered useless if washed and degraded, but you will want to test your assembly after processing and ensure it still falls within specification.
