On conformal coatings¡.
This process is normally used in critical Military gear, although not in the latest generation of COTS equipment.
It renders any repair much more difficult. ?Careful removal is required using special solvents, and any residual coating will complicate soldering with quality. ?Then, one would have to repair or ¡°re-coat¡± with an identical coating to complete.
It also complicates determining component values and obscures their marking.
If this inexpensive device was designed to be submersible, a different watertight enclosure would be warranted. ?In short, driving up costs and rendering the device disposable after failure.
In understanding any design at this point, we must consider cost. ?That is how the world operates now. ?Design centers around a price point. ?Secondary environmental protection is good, using inexpensive plastic items of all sorts.
Can¡¯t speak to the lack of a weep hole, but easily fixed with a small drill bit. ?Not too large, or you will find the item filled with ants or other insects.
