Recommended press cycles: 1. Heating rate (110℃~150℃) 4.0℃/min is acceptable. 4.5℃/min is preferred. 2. Product temperature should be kept at higher 190℃ for more than 90 min to fully cure resin. 3. Pressure should be up to 450psi, high pressure is better for resin flowing and filling in the gaps. 4. Pressure should be kept below 200psi during cooling period. 5. Vacuum should be kept for at least 30 min from start. 6. Cushion for pressure evenness is n
