Item Subject: [TN] Optically transparent epoxy Mark, Is the material used for casting on PCB board? You can try Dexter and Pacific Technology. All these kind of material are high moisture sensitivity and very high CTE. The mismatch of CTE among packaging material can cause delamination and wire break. You must fully understand the interaction of design and material properties. It is suggested the design and material selection should guided by FEM analysis. What is your application?

This epoxy must be very stable and not absorb moisture. Also air bubble must be kept to a minimum. Recommendation on manufacturers, suppliers, or specific products would be much appreciated. Also any information on reliability of these products would be also help. Thanks for your help, J.
