preparation example Construction

[0037] Further, the preparation method of described composite acrylic glue comprises the following steps:

[0038] S11, put acrylic glue, inorganic filler, anti-aging agent, antibacterial and antifungal agent, coupling agent and plasticizer into the temperature-controllable reaction kettle, raise the temperature to 75°C, start the stirrer to stir for 35min-40min, and the stirring speed is 155r / min~160r / min, the mixture A is prepared at this time;

[0039] S12, send the carbon nanotubes and lithium sulfate into the reaction kettle, adjust the stirring speed to 310r / min-350r / min, and obtain the composite acrylic glue after stirring evenly.

[0040] Further, the plasticizer is an epoxy plasticizer.

[0041]Further, the specific steps of defoaming casting technology in S2 are as follows: coating the polyamic acid added with nano aggregates on the carrier, sending it into a tunnel oven, raising the temperature in stages, at 345°C to 250°C , heated for 35min-40min, and then reacte...

Abstract

The invention relates to the technical field of chip accessories, in particular to a carrier tape for a 5G chip PVD process and a manufacturing method thereof. The carrier tape comprises the following components in parts by weight: 30-70 parts of pyromellitic dianhydride, 20-60 parts of dimethyl acetyl, 5-15 parts of composite nanoparticles, 40-90 parts of organic sol, 30-40 parts of p-phenylenediamine, 20-25 parts of polyethylene glycol, 20-25 parts of ethanol, 30-45 parts of an antistatic liquid and 20-30 parts of a composite acrylic acid glue solution. According to the invention, the problems that the existing carrier tape is unstable in viscidity, easy to fall off, easy to remain glue when being taken down, and low in process yield can be effectively solved.
