Encapsulating Printed Circuit Boards

Request Number N079895
Need details
Description

IncWell's partner seeks robust encapsulation technology to protect printed circuit boards (PCBs).

 

Background

Currently, electrical component cooling is accomplished with a thermal interface material (TIM) that resides between the electrical component and the substrate and/or coolplate. This TIM can be costly and is subject to decreasing effectiveness due to age and wear. Additionally, the coolplate itself can also increase the total thermal resistance of the unit.

 

In order to facilitate "direct" water/glycol cooling of PCBs and avoid usage of TIMs, IncWell's partner seeks a technology that can completely enclose the electrical component (such as VIAs, MOSFET, ICs, etc.) - see image below:

 

 

 

 

 

 

The encapsulating technology must tightly conform to the electrical component, be robust in nature (resistant to abrasion from coolant flow, thermal expansion, mechanical strain) and compatible with automative environments.

 

Key Success Criteria

The successful technology will:

  • Provide lifetime resistance to 50/50 water/glycol blend:
    • greater than 8000 hours at 85°C, resting fluid or at coolant flow of 6L/min OR
    • 15 years
  • Protect PCB at operating temperatures between -40°C and 150°C
  • Have low thermal resistance:
    • high thermal conduction
    • low layer thickness
    • high overall HTC > 2000W/m²K
  • Be suitable for serial production in terms of time, cost, and captial expense

 

Additionally, IncWell's partner is primarily interested in solutions that are well developed (TRL = 7).

 

Possible Approaches

Potential approaches include (but are not limited to):

  • Spraying
  • Dipping
  • CVD

 

Approaches not of interest

None.

 

Preferred Collaboration types
  • Joint Development
  • Consulting
  • To Be Negotiated
Items to be submitted

When responding to this request, please be sure to provide a non-confidential description of the technology you propose along with information regarding your alignment with the Key Success Criteria as well as your desired business relationship with IncWell's partner.
