I am looking for a comparison of (3) board types. Advantages/Disadvantages. suitable applications, etc. The (3) types are paper phenolic, CEM 1 and G10. We are presently purchasing a product that uses a paper phenolic board. The board has large components such as transformers and heat sinks. We are finding that the reliability is poor when the assembled product is transported due to components vibrating loose. We are reasonably sure that G10 boards will help the problem. We are not sure of the CEM 1 board characteristics. If someone could help with a comparison of the three it would be greatly appreciated. The operating temperature range requirement is 0 to 60 degrees C. Thanks, John Curtis Diebold Inc.
