Analysis of the Influence of Shrinkage Tensile Stress in Potting Material on the Anti-Overload Performance of the Circuit Board

In this article, the influence of shrinkage tensile stress in potting materials on the anti-overload performance of a circuit board was studied. Firstly, the phenomenon of shrinkage tensile stress in common potting materials was analyzed, and it was found that the commonly used potting adhesives displayed large shrinkage characteristics. Secondly, a small experiment was set up to verify that the shrinkage tensile stress of potting adhesives would lead to printed circuit board (PCB) deformation, and the shrinkage stress was contrary to the acceleration direction of overload. Thirdly, the influence of potting adhesives on the overload resistance of the PCB was analyzed.

Potting And Encapsulating — Avoiding Voids

Formulators of multi-component adhesives, potting and encapsulation materials are careful not to supply products with entrapped air. They do this by manufacturing under vacuum or degassing them before supplying to the end user. Consequently, entrapped air in a mixed material is usually a processing issue.

Maximal Performance Through Vacuum Potting

The performance of electronic components is compromised by factors such as bubbles in the potting medium. Increasing numbers of applications — particularly in the automotive and electronics industries — therefore require completely bubble-free dispensing methods. This is where potting in a vacuum comes into focus. The widespread school of thought about this technology is that it is too ...

Coatings and Pottings: A Critical Update

Conformal coatings and potting materials continue to create issues for the electronics industry. This webinar will dig deeper into the failure modes of these materials, specifically issues with Coefficient of Thermal Expansion (CTE), delamination, cracking, de-wetting, pinholes/bubbles and orange peel issues with conformal coatings and what mitigation techniques are available. Similarly, this webinar will look at the failure modes of potting materials ...

OXidation of EEE components, is there a standard to follow or some good GMP's -- Are there standards that dictate how long a EEE component can be exposed outside of a nitrogen bag before oxidation occurs? Since Covid I am seeing more and more caps and resistors that seem to have oxidation and do not solder well....

BTU VIP70 Indicator lights -- We have a BTU VIP70, but the traffic lights on top aren't connected anywhere. I've had a hunt around and can't find the appropriate connector inside, or where to connect them to. Does anyone know where these connect to please. Cheers
