Avoiding voids in aerospace potting applications
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 […]

Dispensing automation: an ROI story
“I am the Managing Director of an electronics CEM. We are making 1,000 potted electronics assemblies per week, regularly 200 per day. This is done manually by experienced operators. Pat is my best operator, she’s been with me the longest time. Some weeks, about 2.5% of these are rejected after potting. Each one costs £50, […]

adhere academy: what does hygroscopic mean?
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 […]
