Storage Condition

储存条件

■在温度小于20℃，湿度小于50%可存放90天；小于5℃条件下可存放180天。

■20℃, 50%RH for 90 days ；max 5℃ for 180 days.

压合概论

■PP应在堆叠室内进行，避免吸湿。

■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 must be prepared in lay-up room to avoid moisture absorption.

■Stacks with the core and prepreg is recommended to use the vacuum process for 60min when being heated.

建议压合条件

■升温过程                              

a.  温度范围为80-120℃                b.  升温速率为1.2-2.0℃/分钟         

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

■为使树脂固化完全，料温在170-180度最小保持45分钟

■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。

■Heating

a.Temperature Range=80-120℃          b. Rate:1.2—2.0℃/min

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

■Temperature of materialin170-180℃ must be held for at least 30mins to make the epoxy solidify completely. 

■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.
