What Is Causing a White Scale Buildup at Copper Pin Connection on LED Light Sticks and How Can They
On top of that I would like to add following.IP65 has a complete protection against water jets and is dust proof.
The protection level itself forms a part of the problem due to the following.A lower temperature of the enclosure in relation to the surrounding air causes a difference in pressure with an inflow of outside air as result. If the temperature becomes low enough the moisture in the air starts to condense. Compare this with dew in the morning. Now the trouble starts.Water can't escape. Only when the inside enclosure temperature becomes high enough to evaporate the water or prevent condensation in the first place and the inside presure becomes higher than the outside pressure the vapour is forced out and corrosion is prevented. Any encloser with enough heat production or forced dry air is able to fulfill these conditions. The connector presented by OP does not fulfill these conditions and corrosion can not be prevented.The only way out is to use enclosures that can ventilate to the outside and yet are protected against splash or sprayed water. For this the IP standard does not yet offer any help.You can try to clean but the problem remains.
Can someone explain what is causing this white scale to appear on the copper pins and on the block of this LED light connection? The seal at the connection is supposed to be watertight. On occasion, there is a white (crystallization) that forms at the PC board, pin and on the block at this connection. These lights are exposed to sun and rain and are located 5 miles from coastal waters. There is power and data flowing through these connects and both get affected causing the lights to go out.!( ·OTHER ANSWER:
