"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?
