*以下为我司常规规格,可根据客户要求生产。
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.
■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.
■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.
