Preparation process of carrier tape base material capable of improving thermal expansion performance
The invention belongs to the technical field of preparation of carrier tape base materials, and particularly relates to a preparation process of a carrier tape base material capable of improving thermal expansion performance. The preparation technology of the carrier tape base material capable of improving the thermal expansion performance comprises the following steps that 2-3 glass fibers are wound together to form a glass fiber bundle; glass fiber bundles are pre-soaked in molten PET resin, so that the surfaces of the glass fiber bundles are wrapped with a layer of micron-sized resin, and the wettability of subsequent resin is improved; curing and weaving the pre-impregnated glass fiber bundle to form a blank of the glass fiber cloth; the glass fabric blank passes through molten PET resin in a roll-to-roll mode, passes through a drying tunnel to be shaped, and is placed in a drying oven to be subjected to semi-curing operation. The invention provides a preparation process of a carrier tape base material capable of improving thermal expansion performance. The problems that an existing carrier tape base material is too high in cost, poor in heat resistance and prone to deformation at high temperature are solved.
本发明属于载带基材的制备技术领域，具体涉及一种提高热膨胀性能的载带基材的制备工艺。所述的提高热膨胀性能的载带基材的制备工艺，包括以下步骤：将2‑3根玻璃纤维缠绕在一，形成玻纤束；将玻纤束预浸熔融的PET树脂，使玻纤束表面缠裹一层微米级树脂，增加后续树脂的浸润性；将预浸的玻纤束固化，编织，从而形成玻璃纤维布的毛坯；将玻纤布毛坯卷对卷通过熔融的PET树脂，经过烘道使之定型，并放在烘箱中进行半固化操作。本发明提供一种提高热膨胀性能的载带基材的制备工艺，解决现有载带基材成本过高，耐热性差，高温易变形的问题。
