以上為我司常規(guī)規(guī)格,可根據(jù)客戶(hù)要求生產(chǎn)

The above is the regular specifications of our company, which can be produced according to the customer's
requirements

儲(chǔ)存條件 Storage Condition
■在溫度小于 20℃，濕度小于 50%可存放 90 天；小于 5℃條件下可存放 180 天。
20℃, 50%RH for90 days ；max 5℃ for 180 days.

壓合概論 Lamination Overview
■PP 應(yīng)在堆疊室內(nèi)進(jìn)行，避免吸濕。
Stacks must be prepared in lay-up room to avoid moisture absorption.
■疊合好的 PP 與芯板壓合開(kāi)始時(shí)建議最小保持 60 分鐘的抽真空狀態(tài)。
Stacks with the core and prepreg is recommended to use the vacuum process for 60min when being heated.

Recommended Press Cycle

升溫過(guò)程                                             ■  Heating
a. 溫度范圍為 80-120℃                        a.Temperature Range=80-120℃
b. 升溫速率為 1.4-2.5℃/ 分鐘               b. Rate:1.4—2.5℃/min
注意：這些數(shù)值僅供參考，當(dāng)機(jī)器和材料結(jié)構(gòu)不同時(shí)這些值可能做調(diào)整

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

■ 為使樹(shù)脂固化完全，料溫在 170-180 度最小保持 30 分鐘
Temperature of material in 170-180℃ must be held for at least 30mins to make the epoxy solidify
completely.
■ 為避免板彎翹，冷壓時(shí)材料在 100℃以上時(shí)冷卻速率保持在 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.
