1) Laminates at 75psi, cured at 160°C for 6 minutes. Lap Shear tested at 25°C. 2) The ASTM D149 test method was completed on cured Bond-Ply LMS 500P material. No pressure was applied to the product during the cure cycle. Actual application dielectric performance will vary with primary dependence on consistent material handling of Bond-Ply LMS 500P in the pre-cured or "green" state and applied pressure and dwell time during the lamination process. 3) TO-220 Thermal Performance testing, per The Henkel RD2010 specification for Laminates, was completed on pre-laminated TO- 220 assemblies. Lamination was completed at the pressure levels referenced above. Actual pressure during performance testing was limited to the inherent weight distribution of the TO-220 component. No additional pressure was applied. |
