Waterproof PCB By Methods of Waterproofing (5)

  • Structural Waterproofing

    The Structural Waterproofing can provide adequate waterproofing to the board. In addition, it is simple to deploy and has minimal risk of PCB damage. However, it can’t always be efficient under particular situations.

  • Potting Waterproofing

    The Potting Waterproofing drenches a water-resistant compound to the board to apply a protective layer. One advantage is that it offers resistance to shock and outstanding protection against weather conditions.

  • Dipping Waterproofing

    The Dipping Waterproofing submerges the board into a waterproof coating solution. Then, withdraw it after it has been cured. Also, this can be ideal if you plan to perform do-it-yourself (DIY) waterproofing.

  • Surface Coating Waterproofing

    The Surface Coating Waterproofing can also be an alternative to dipping if you plan to conduct DIY waterproofing in your home. In addition, it is the least expensive method. However, it is not ecologically friendly.

  • Spray Waterproofing

    The Spray Waterproofing, as its name indicates, the waterproofing solution is applied through an aerosol spray. It is recognized to be the easiest method to use in terms of waterproofing your circuit board.

Waterproof PCB By Surface Treatment (5)


    The HASL PCB is considered this board’s most valuable type of surface finish. In addition, one of the reasons for it becoming the most popular finish is that it is highly resistant to corrosion and economically friendly.


    The ENIG PCB is the most recommended finish for this type of board, similar to the HASL one. It is because it offers a flat finish to the board, provides a strong solder connection, and has corrosion resistance.

  • Immersion Silver PCB

    The Immersion Silver PCB offers exceptional flatness to the board. Moreover, it is a reasonably priced finish, given that it is lead-free and halogen-free. However, it can be sensitive to handling and tarnishing.


    The OSP PCB works pretty well on flat surfaces; it can be reworked, has a simple and easy application process, and is lead-free and halogen-free; thus, it complies with the RoHS regulations, and it is economical.

  • Carbon Ink PCB

    The Carbon Ink PCB is recognized to be a good alternative for the hard gold finish since it is way more robust and reliable compared to other types of finishes. However, it requires proper care and cleaning.

Impedance Control for Waterproof PCB

Since impedance control provides stability that forms in current conduction, it is essential to ensure that it is up to standards.

Generally, an electrical component’s dielectric dimensions and electric permittivity may affect its impedance.

Hence, we want to share with you the things to consider looking out for to attain impedance stability. This includes choosing the most effective materials.

Additionally, you might also want to look out for its temperature control. Also, in terms of the current load of the PCB, we recommend calculating its dielectric thickness.

Please write or call us if you would need a more thorough explanation of these.

Testing Performed for Waterproof PCB

To ensure the performance of the Waterproof PCB, we perform all sorts of inspections and tests established by the international guidelines.

However, in this section, we will only share two (2) of them since they are considered the most crucial tests we conduct.

We perform Flying Probe Test, wherein we use these conductive probes to touch the board’s surface. In addition, this can test the wirings, faulty connections, etc.

Then, we have the Automated Optical Inspection (AOI), wherein a machine captures an image of the board; it will compare it to a perfect PCB to check for flaws.

Kindly contact us right away if you have questions about the other tests.
