杜邦干膜自有优势：
DuPont Dry Film has its own advantages:

1.湿法贴膜技术：
1.Wet lamination technology:

       湿法贴膜装置搭配专门为湿法贴膜应用而设计的干膜阻剂，于压膜前在洁净的铜面上涂覆一层厚度均匀，连续的水膜，然后连续压膜，有效改善了干膜的流动性，密着性，从而减少界面气泡等压膜缺陷的产生。
      The wet laminating device is equipped with dry film resist specially designed for wet laminating applications. A uniform and continuous layer of water film is applied to the clean copper surface before laminating, and then the film is continuously laminated, which effectively improves the flow and adhesion of the dry film, thus reducing the generation of laminating defects such as interface bubbles.

湿压优点：
Wet press advantages:

◆降低了干膜阻剂的粘度，增强了干膜的流动性。
◆Reduces the viscosity of dry film resist and enhances the fluidity of dry film.

◆提高了干膜填埋深坑的能力，提高影像转移中的良品率。
◆Improved ability to fill deep pits with dry film and improved yield in image transfer.

◆消除了板面静电，起到板面清洁作用。
◆Eliminates static electricity on the board surface and plays a role in cleaning the board surface.

◆节约了固定资产的投入，省略了相应的塞孔/磨板/预热机等设备固定资产的投资。
◆Save the investment of fixed assets, omitting the investment of fixed assets of corresponding equipment such as plug hole/grinding plate/preheater.

2.独特的专利配方：
2. Unique patented formula:

       杜邦干膜以领先的配方，在图形制作过程中，能获得干净的显影效果。
       DuPont dry film is formulated with leading-edge technology for clean development during graphics production.

 ◆良率得以改善，显影Sludge析出量极低。
◆The yield is improved, and the amount of Sludge precipitation is extremely low.

 ◆减少清洗显影槽的成本：洗槽化学品，人工成本，停机时间，更换喷嘴以及清洗用化学品对显影缸及部件的损害。
◆Reduce the cost of cleaning the developer tank: tank cleaning chemicals, labor costs, downtime, nozzle replacement, and damage to the developer tank and components from cleaning chemicals.

 ◆更加环保，消除健康危害。
◆More environmentally friendly, eliminating health hazards.
