Waterproof PCBA
$35.90
Waterproof PCBA is the assembled circuit board that is specially treated to resist water ingress so as to ensure consistent functionality and reliability in harsh or wet environments. It is usually designed for outdoor applications, such as wearable devics, marine equipment, automotive electronics, and so on.

Questions & Answers
1. What is the typical IP rating of a waterproof PCBA?
The typical IP rating for waterproof PCBA ranges from IP65 to IP68. The exact rating depends on the enclosure design and the sealing techniques.
2. Is conformal coating enough to make a board waterproof? What other measures can be taken for complete waterproofing？
Conformal coating alone is not enough to fully waterproof a board, as it doesn’t seal the board completely. For complete waterproofing, we may also use waterproof connectors, sealed enclosures, and other waterproofing measures to ensure robust waterproofing in harsh environments.
3. Will waterproofing affect PCB heat dissipation?
Yes, waterproofing will impact heat dissipation, especially when the PCB uses potting compounds or conformal coatings.
4. What tests are performed on waterproof PCBAs?
The general tests include IP rating compliance test, high-humidity and thermal cycling tests, electrical insulation resistance test, X-ray scanning, and other tests. Those tests are performed to ensure reliability in high-moisture environments.
5. Do waterproof PCBAs affect signal integrity?
Generally, waterproofing has an ignorable impact on signal integrity if the PCB is well done. The poorly designed PCBA with non-uniform coatings may affect signal integrity and cause capacitive interference.
6. What are common surface finishes for waterproof PCBs?
The common surface finishes of waterproof PCBs include ENIG, OSP, Immersion Tin or silver, and more. ENIG is the most popular one.
