1/ What is an onboard charger and its function?
The onboard charger is an essential connection between the electric vehicle and the power grid. Its main job is to convert the AC electricity coming from the charging station into DC power so that the EV’s battery can store it. The onboard charger also controls the charging, keeps an eye on battery life, and guarantees safe and effective charging.
2/ What is Prostech’s solution for Onboard charger in Evs
Prostech offers a wide range of materials used for any manufacturing stage from PCB assembly to the final box build process.
a/ Soldering materials
Surely, soldering materials are essential to create a permanent bond between components on PCB substrate (usually FR4 substrate). Various products can be considered:
- Solder wire for mounting small components.
- Solder bar with liquid flux for wave soldering process.
- Solder pastes for SMT process.
- Others: Solder preform, BGD sphere, bumping solder paste, or solder ribbon.

c/ Conformal coating
-To protect components from any environmental factors: moisture, dust, chemicals, … A thin conformal coating layer is necessary. Usually, silicone coating is considered because of its high temperature resistance, high flexibility and excellent moisture, and chemical resistance.
Please refer to some popular silicone coating products below for some components provided by Prostech:
| Momentive Conformal Coating ECC3050S | Momentive ECC3051S Solvent Free Conformal Coating |
 |
 |
-Some components also require fixing to protect under vibration condition. Silicone adhesive is the suitable and good selection to meet these condition. Prostech provides this type of adhesive with guaranteed quality. Refer to these Prostech’s silicone adhesive products below:

d/ Thermal conductive potting material
At inductor or DC-DC transformer, where the working principle mostly based on electromagnetic can result in high temperature, a thermal conductive potting material is preferable to :
- Protect the Copper coil under vibration.
- Seal those areas for water resistance.
- Rapidly and effectively conducting heat away from component, supporting for longevity of the whole system
‘Contacts us now so as to receive suitable solutions for onboard charger. Refering some our popular products below:
- Thermally Conductive Material SilCool™ TIA208R
- LIPOLY PK404DM Two-Part Thermal Conductive Gap Filler
e/ Thermal interface materials (TIMs)
-TIM is an indispensable product in the EV industry since it supports dissipating and conducting heat away from components (Mosfet, rectifier diode, …) more effectively by eliminating the air gaps and reducing the interface resistance.
-The form of material varies depending on the gap between heat source and heatsink, thermal conductivity, and adhesion,…

f/ Using CIPG/FIPG
CIPG/FIPG is used to seal and protect the whole system from water, dust and ensure no leakage of coolants.
‘To obtain detailed information about CIPG/FIPG and the materials used for CIPG, access this article to receive the documentation from Prostech.’
Prostech offers an adhesive that meets the aforementioned requirements. Momentive RTV133 – Black Silicone is indeed the best choice with its heat resistance and good water resistance, as recommended by Prostech for using CIPG in onboard chargers.
g/ Threadlocker
Threadlocker is recommended to use at threaded fastener in the flange area with 2 main purposes:
-Thread locker is an effective solution for onboard chargers to secure screws, bolts, or other components in place during operation. Thread locker is a type of adhesive designed to prevent loosening and keep elements fixed together. When applied to threaded screws and bolts, thread locker creates a protective layer against vibration and loosening.
-When used in an onboard charger, thread locker can help maintain stability and durability of critical components, minimizing the risk of damage and electrical leakage. Especially in the environment of electric vehicles, where vibration and high temperatures can cause connection loss or reduce charging efficiency.
Please contact us immediately to receive the most detailed advice from our technical team on using threadlocker for onboard chargers. Additionally, you can explore information about two popular adhesive types with just one click on the products below:
