"You don't belong here" printed on the overlay- so thats why its fuched. Proudly says RoHS on the casing, rustling noises at random, so fuched by RoHS probably, certainly PbF solder. How to get under the scrappy looking black "conformal" coating. Not epoxy coating as methylated spirit softened this plasticky coating enough to scrape off with a wooden cocktail stick on the Main chip Spin FV-1 , nice to see datasheet for this on their site , and also 5532. Seems suspect solder on a pin of the main chip, from twizzle sticking. But what is the cleanest way to get the coating off - it hardly looks pretty as it is, am concerned about meths migrating capilliary fashion along the pins, to deal with the underlying pbfitis. Chemical reaction between this black stuff and solder?
