ACI Technologies (ACI) is working on a project where one of the challenges is removing a large quantity of heat from audio amplifier circuits. This challenge is further complicated in that the heat generating circuits are located in a rack mounted box that needs to be shielded from electro-magnetic interference (EMI). Mechanically, this means that there cannot be open passages into the rack mounted box. We will first review the basic types of cooling available as commercial off-the-shelf (COTS) systems for the electronics industry, then discuss the pros and cons of each for different applications, and finally reveal the criteria and solution for the ACI project.

Every industry has every unwritten rules, like IC shipping tube moq is high in packaging tube industry rules! This regulation is not to be difficult for customers, but the cost of the problem, as long as the manufacturers feel that even a small amount of packaging tube can do and do too.

What affects the price of boards? Number of layers: Limit the number of layers as much as possible. If higher quantities are anticipated, spend the extra time and money in engineering to minimize layer count....

Thermal influences can significantly compromise the service life, capacity and especially the operational safety of HV batteries. In order to prevent damage due to excessive temperatures, large quantities of heat-conducting potting media are used here. Scheugenpflug has developed a new system solution for fast and reliable application of these materials.

Issue: Moisture and bubbles in your dispensing material with larger quantities Solution: Scheugenpflug’s 55-gal Barrel Agitator Station Barrel agitators for casting resins take their technology from the paint sector. They fall short of meeting the special demands of the auto, medical, aeronautics and electronics industries. They can’t guarantee a solid seal on the barrels – often containing expensive, moisture sensitive resins – allowing the humidity of the surrounding environment to damage the material. Also, conventional barrel agitators, as opposed to smaller units, cannot work in a vacuum to process materials directly.

We notice that the quantities of material that are to be dosed are becoming more and more divergent. In addition to large media volumes, small and very small quantities are also increasingly coming into focus. For example autonomous driving: These vehicles already produce an immense amount of data today. When potting the associated sensors, cameras, and ECUs, it is important to ensure a precise and repeatable media application – even with volumes of only 0.03 ml. In contrast, when high-voltage batteries for electric cars are potted, 5 to 10 litres of heat-conducting paste are required per vehicle – and the trend is rising. Optical bonding used in display production, on the other hand, is in the medium volume range. The challenge now is to cover the entire volume spectrum reliably and in compliance with the required cycle times. This is remedied by a modular system of scalable modules, which offers the customer the necessary flexibility and enables him to plan a system according to his needs.

Particulate matter contamination is known to become wet and therefore ionically conductive and corrosive if the humidity in the environment rises above the deliquescence relative humidity (DRH) of the particulate matter. In wet condition, particulate matter can electrically bridge closely spaced features on printed circuit boards (PCBs), leading to their electrical failure. (...) The objective of this paper is to develop and describe a practical, routine means of measuring the DRH of minute quantities of particulate matter (1 mg or less) found on PCBs.

A new PCB surface finish has been developed that offers outstanding performance and excellent environmental protection. This finish has the potential to replace more common finishes such as ENIG, ImAg, ImSn, ENEPIG, or OSP with a chemically resistant plasma deposited coating. The substitution of the wet processes with this dry plasma process offers significant advantages e.g. lower quantities of chemicals used, environmental benefits and improved operator safety.
