When Rotech Systems and Encoders discovered that its existing potting compound was being discontinued, the problem exposed a deeper constraint in its production system. Uncertain material supply had already been limiting output of the rotary encoders and vibration sensors used in harsh mining environments. Without reliable access to encapsulation materials, the company could not confidently […]

Engineers sometimes ask us whether they can use an adhesive as a potting compound, or whether a potting material could double as an adhesive. The answer lies in the chemistry and in the way these materials are tested and profiled. The question typically revolves around epoxy and polyurethane products. Head of Learning and Development Kevin […]

When CSignum set out to develop the EM-2, a groundbreaking subsea wireless device, they faced a challenge familiar to many technology manufacturers: how to protect sensitive electronics in an unforgiving environment without going back to the drawing board. Instead of a costly redesign, CSignum worked with Intertronics to find a practical solution. With advice from […]

Coating, encapsulation, or potting – which is right for protecting your electronics? In this JoinedUpMinute, Ian explains the key differences between three common protection methods: Coating (aka conformal coating) — a thin protective film over a PCB assembly Encapsulation (sometimes called ‘glob topping’) — a thicker layer over specific areas Potting — filling an enclosure […]

Two part adhesives, potting compounds and similar materials need to be mixed in the correct ratio of the two parts in order to achieve the properties stated on the product data sheet. In many cases, this is easy. Most of our two part structural adhesives are packaged in two-part cartridges with static mixing nozzles, so […]

Formulators of potting materials for aerospace electronics applications are careful not to supply products with entrapped air. Consequently, entrapped air is usually a processing issue which can compromise thermal conductivity and heat dissipation, or the electrical insulation properties. Voids and delamination can also provide pathways for moisture and other contaminates, weaking the physical structure. If […]

Hygroscopic materials attract and absorb humidity from the air. An example is the way granulated sugar gets lumpy in the sugar bowl or salt clumps in the salt shaker blocking the holes when in humid environments like a steamy kitchen. Lots of materials are hygroscopic, including paper, isopropyl alcohol (IPA), and plastics like ABS. Nylon […]
