Thank you for your reply. Many years ago when I was in design, the circuitboards of equipment for worldwide use, after assembly were dipped in conformal coating to prevent corrosion and other damage from the environment. I travel in the tropics a lot and notice for example, that laptop USB port and earphone socket connections become unreliable unless protected by covers. Likewise, on some laptops, internal connections, eg HDD connectors get unreliable, showing signs of corrosion.
I see the NUC uses outside air for ventilation. I have 2 questions on that: Is the D54250WYK and Wireless-AC 7260 protected against the environment with conformal coating or equivalent ?
I seem to recall, also many years ago, on cheaper unprotected equipment, for 'aftermarket use' there was a silicone sealant applied from an aerosol can, which being soft, could be easily removed if circuit components or multi-board assemblies need to be replaced.
Can you recommend a commonly available (from amazon.com or similar) coating, that can be safely applied to the assembled NUC board to protect the completed kit, including its RAM, SSD, 7260.HMW ?
At last I see UK vendors beginning to stock the Haswell NUC, eg. AmazonUK but part no. is 'BOXD54250WYK', which according to a much earlier Intel post is 'pre-production' without a power cord and that 'production' units for UK will have '3' appended to the part no with UK power cord. Apart from buying a mains lead separately, is there any other disadvantage in buying the 'pre-production' part ?
Thank you
