Electric motor, power controller, inverter, converter and other electronics related to the powertrain of an electric car are during operations exposed to high temperatures. Not only by the heat generated by moving parts but also due to the high power on which they operate. In ICE cars there is a similar exposure to high temperatures and refers to all electronics which are located under the hood.

Voids in the solder joint reduces the thermal dissipation and hence the reliability of the assembly. Using a paste especially developed to minimize the amount and size of voids under specific sensitive components is recommended and will improve the overall reliability.

Weight is key in automotive so when possible light weight aluminium or other alloys are used. When oil or grease need to be removed, choosing the right cleaning agent is critical as aluminium and other light alloys are quite sensitive. They could be damaged when using a non adapted cleaning product. Solvent systems are mostly harmless to all metals but for water based cleaners caution is required. We offer water based cleaners especially designed to remove oil & grease from sensitive metals. Despite some of them having a medium to high alkaline pH to allow efficient cleaning, they don`t damage these metals.

Inventec has developed a full range of cleaning agents for removal of oils & grease suited to you desired process.

Iron parts are sensitive to corrosion and may need a temporary protection in between subsequent processes of machining the part. Inventec has several cleaning solutions dedicated for oil & grease removal with a temporary protection agent included in the formulation. This could avoid an extra process step and will reduce the total process time.

Not only the fabricated parts need degreasing but also die-molds for aluminium casting in the maintenance process.

The idea behind No-clean soldering is to avoid an additional cleaning step in your overall process. For certain critical applications however, there is no room for failure and removal of any contaminations left on the PCB is required. This is especially true for the automotive, Aerospace and Medical industry, where the expected life-time of the electronics are many years and where some electronic devices are critical for health & safety.

It is common knowledge that assemblies exposed to higher temperatures are more prone to electrochemical migration and leakage current. This makes cleaning of PCB’s exposed to this kind of environment a valuable choice. Also when applying a protective coating it is also advised to clean prior to the coating process in order to maximize the coating adhesion.

Inventec has developed a dedicated range of defluxing agents suited to you desired process. Designed to cater high volume assemblies with a fast and effective cleaning and with high regards to their environmental impact.

In order to extend the life time of your electronic assembly and protect it against harsh environments they operate in, coating is a valuable option. Also they can provide additional mechanical strength to the assembly by absorbing vibrations.

Inventec offers several conformal coatings & ultra-thin coatings. Ultra-thin coatings offers a more simple and cost advantage process, while traditional conformal coatings provide a more rigid protection. They both can be applied by selective spray or by dipping.

Although heat curing of conformal coatings is still very popular, we believe in the future of UV curing. Especially by using UV LED instead of the traditional mercury UV lamps, which is a more stable, cost-efficient and environmental processes.

When applying a protective coating it is also advised to clean prior to the coating process in order to maximize the coating adhesion. With Inventec you have a partner which can offer you soldering, cleaning and coating solutions. Designed to be compatible with each other to minimize the risk of compatibility issues.
