LED Encapsulation for Consumer Products

In one of our Consumer Electronics projects, a smart lighting company wished to dispense silicone-based LED encapsulation material for two different product sizes. The larger product had a 9mm circular dam which required silicone dispensing flush with the top of the dam. The smaller product had a 1mm LED die that required only the top to be encapsulated. The material consisted of two parts which were mixed by weight in a 1:1 ratio. A phosphor powder was added totaling 10% of the overall weight. The phosphor required agitation to remain suspended.

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 ...

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.

Resource-efficient adhesion and potting technologies in electronics manufacturing

Saving resources in electronics manufacturing is not an end in itself. It is closely linked with reducing costs and gaining a competitive advantage. However, innovative adhesion and potting technologies in combination with highly functional adhesives and potting media make a significant contribution to the ideal union between economic performance and a reduced ecological footprint.

Potting in a Vacuum or Atmosphere?

Potting in a vacuum or atmospheric conditions? This question about the correct procedure concerns many users, among others i.e. electronics manufacturers, who pot more and more complex parts and components for a huge variety of products. Against the actual requirements of product and process, a decision on the procedure is often made under the assumption: "Potting under atmosphere = affordable and easy" and "Potting under vacuum = expensive and difficult". But that's a thing of the past. The way to the correct method, however, requires the clarification of a number of factors.

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.

Potting Compounds Protect Electronic Circuits

Product reliability is an absolute must for manufacturers to succeed in today's competitive marketplace. As customers demand ever increasing levels of performance at lower unit costs, it becomes increasingly challenging to ensure that electronic circuits operate as designed for a prolonged period of time. Delicate components, densely populated printed circuit boards (PCBs), confining packaging, and highly demanding service environments have the potential to lead to increased failure rates as a result of excessive heat build-up and electrical interference.
