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.

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.

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 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.

pad solderbility problem -- hello can anyone help me what might cause the problem for some pads paste deposit is missing i checked reflow profile and paste deposit on pcb

Heller Reflow Oven Fan Noise -- We acquired a Heller 1809 MKIII and the fan on the bottom side of zone one makes a high pitched hum while the oven is at room temp. Once the oven starts to heat up, the noise goes away. The bearings were in bad shape, so we replaced those but it didn't fix the problem. We have found that if we lower the fan slightly, the noise goes away too but cant find anything that is interfering with the fan. Does anyone have any ideas?
