压合概论 Lamination Overview
■PP 应在堆叠室内进行，避免吸湿。
Stacks must be prepared in lay-up room to avoid moisture absorption.
■叠合好的 PP 与芯板压合开始时建议最小保持 60 分钟的抽真空状态。
Stacks with the core and prepreg is recommended to use the vacuum process for 60min when being heated.

升温过程                                             ■  Heating
a. 温度范围为 80-120℃                        a.Temperature Range=80-120℃
b. 升温速率为 1.4-2.5℃/ 分钟               b. Rate:1.4—2.5℃/min
注意：这些数值仅供参考，当机器和材料结构不同时这些值可能做调整

Note: these values are reference only they may change depending on machine and material structure

■ 为使树脂固化完全，料温在 170-180 度最小保持 30 分钟
Temperature of material in 170-180℃ must be held for at least 30mins to make the epoxy solidify
completely.
■ 为避免板弯翘，冷压时材料在 100℃以上时冷却速率保持在 2.5℃/min 以下。
Cooling rate of material should be kept under 2.5℃/min when the temperature of material is over
100℃,in order to avoid introducing twist.
