  • Patent number: 12152173
    Abstract: A composite polyester hot-melt adhesive, a preparation method thereof and a preparation method of an anti-scouring geotextile are provided. The preparation method of the composite polyester hot-melt adhesive includes the following steps: performing an esterification reaction on a dibasic acid and a dihydric alcohol under a protection of nitrogen and an action of a titanium/cobalt composite catalyst, adding a stabilizer for a polycondensation reaction to obtain a polyester hot-melt adhesive, then adding polymethyl methacrylate (PMMA) microspheres for mixing and stirring to obtain the composite polyester hot-melt adhesive. The anti-scouring geotextile is obtained by bonding a polyethylene terephthalate woven fabric with a polypropylene geotextile by the composite polyester hot-melt adhesive.

  • Publication number: 20210161013
    Abstract: This application provides a printed circuit board. The printed circuit board includes a first outer conducting layer, a second outer conducting layer, and at least one insulation medium layer sandwiched between the first outer conducting layer and the second outer conducting layer. The printed circuit board includes a gold finger area and a soldering area. A total thickness of all conducting layers in the gold finger area is greater than that of all conducting layers in the soldering area. Because the total thickness of all conducting layers in the gold finger area is relatively thick, resistance of the gold finger area can be reduced, and a through-current capability of the gold finger area is improved. In addition, the total thickness of all conducting layers in the soldering area is relatively thin, so that a sufficient soldering temperature and a good soldering effect can be ensured.
