The purpose of the present invention is to obtain a fluorine-containing compound which is easily stabilized without irradiation of ultraviolet light, by efficiently converting a CI bond in an iodine-containing compound having a group represented by CFRfI (wherein Rf is a fluorine atom or a perfluoroalkyl group) to a CH bond. A method for producing a fluorine-containing compound having an iodine atom content reduced than the following iodine-containing compound, which comprises subjecting an iodine-containing compound having a group represented by CFRfI (wherein Rf is a fluorine atom or a perfluoroalkyl group) to deiodinating treatment in the presence of an organic peroxide and a hydrogen-containing compound having a group represented by CHR.sup.1CHR.sup.2CHR.sup.3 (wherein R.sup.1, R.sup.2 and R.sup.3 are each independently a hydrogen atom or an alkyl group).

Methods, systems, and assemblies for cooling an electronic component are disclosed. A heat sink assembly includes first and second substrates. The first substrate is in thermal contact with the electronic component. A primary channel is formed in the second surface of the first substrate. The primary channel is configured to direct cooling fluid for cooling the electronic component. An array of primary cooling fluid fins is positioned within the primary channel. The array of primary cooling fluid fins includes upstream solid fins and downstream open fins each having an upstream opening and downstream sidewalls. The secondary channel is formed within the second surface of the second substrate and is configured to direct partially heated cooling fluid away from the electronic component. An array of secondary cooling fluid fins is positioned within the secondary channel downstream. An enclosing layer seals the secondary channel.
