Description
塑料组合物及其表面选择性金属化方法 技术领域 Plastic composition and surface selective metallization method thereof
本发明涉及一种塑料组合物及其表面选择性金属化工艺。 背景技术 The present invention relates to a plastic composition and a surface selective metallization process thereof. Background technique
传统的电子行业、信息产业的电路制备主要依赖化学和光化学的方法, 这 些方法在初期的布线过程中, 必须经过照相底片、 曝光、 显影和蚀刻等多道工 序才能完成。 随着电子工业的迅速发展, 对产品设计开发的时间, 价格, 小规 模生产能力都提出了更高的要求。 而传统的技术显示出工序过多、 周期过长的 缺点。 The circuit manufacturing of the traditional electronics industry and the information industry mainly relies on chemical and photochemical methods. These methods must be completed in a plurality of processes such as photographic film, exposure, development and etching in the initial wiring process. With the rapid development of the electronics industry, higher requirements have been placed on the time, price, and small-scale production capacity of product design and development. The traditional technology shows the disadvantages of too many processes and long cycles.
因此, 电子工业中的激光直写技术应运而生。 LPKF公司发明了一种激光 直接成型 ( Laser Direct Structuring-LDS )技术, 釆用添加有某种非导电性有机 金属复合物的塑料为原料, 直接把激光光束投射在注塑件表面上,被照射过的 部分可进行化学镀沉积金属。 该技术中塑料件无需经过专门的粗化、 敏化、 活 化处理, 直接经激光照射后即可进行化学镀, 且工艺流程短, 操作简单, 生产 柔性大, 线宽、 线距精度高。 但是釆用 LDS技术必须要用具有 LDS性能的塑 料, 该塑料内含某种非导电性有机金属复合物, 而进行激光照射塑料件时, 只 有表面需要化学镀的部位经激光照射发生了活化,其他未经激光照射的部位不 发生活化,因此未活化塑料中的有机金属复合物没有得到利用,造成很大浪费。 Therefore, laser direct writing technology in the electronics industry came into being. LPKF invented a laser direct structuring (LDS) technology, which uses a plastic with a non-conductive organometallic composite as a raw material to directly project a laser beam onto the surface of an injection molded part. The part can be electrolessly deposited with metal. In this technology, plastic parts do not need special roughening, sensitization and activation treatment, and can be electrolessly plated directly after laser irradiation, and the process flow is short, the operation is simple, the production flexibility is large, the line width and the line spacing precision are high. However, LDS technology must use plastics with LDS properties, which contain certain non-conductive organometallic composites. When laser-irradiated plastic parts, only the parts whose surface needs electroless plating are activated by laser irradiation. Other parts that are not irradiated with laser light are not activated, so the organometallic complex in the unactivated plastic is not utilized, resulting in great waste.
CN1772949A中公开了一种激光诱导选择性化学镀方法,该方法釆用聚乙 烯吡咯烷酮 /银胶体涂布在基体上, 用紫外激光进行选择性辐射, 在辐射区域 的胶体银中的银离子被还原成金属银粒子并嵌入基体中,未经辐射区域的胶体 银被清洗掉, 然后实施化学镀即可得到基体上微米级图形化的化学镀层。但采 用该方法进行选择性化学镀,涉及到银污染问题。由于该专利中使用的硝酸银、 曱酸银、 乙酸银、 丙酸银、 丁酸银在日光照射和受热情况下容易分解, 因此在 实际操作过程中, 容易造成非激光辐射区域的银污染, 即使清洗, 也难以完全 清除, 在化学镀铜后, 基体表面非激光辐射区域也会有部分镀层; 另外, 通过 涂布聚乙烯吡咯烷酮 /银胶体的方式, 然后采用激光辐射使银粒子嵌入基体中, CN1772949A discloses a laser-induced selective electroless plating method, which is coated on a substrate with polyvinylpyrrolidone/silver colloid, selectively irradiated with an ultraviolet laser, and silver ions in colloidal silver in the irradiated region are reduced. The metal silver particles are embedded in the matrix, the colloidal silver in the unirradiated region is washed away, and then electroless plating is performed to obtain a micron-scale patterned electroless plating on the substrate. However, selective electroless plating using this method involves silver contamination problems. Since the silver nitrate, silver citrate, silver acetate, silver propionate, and silver butyrate used in the patent are easily decomposed under sunlight and heat, it is easy to cause silver contamination in the non-laser radiation area during actual operation. Even if it is cleaned, it is difficult to completely remove it. After electroless copper plating, the non-laser radiation area on the surface of the substrate may also be partially plated; in addition, by coating the polyvinylpyrrolidone/silver colloid, then the laser particles are embedded in the matrix by laser irradiation. ,

Instantly softening and sinking, and the photocatalyst in the plastic composition is relatively floated out of the high molecular polymer, so that part of the photocatalyst in the plastic composition is exposed; then the laser etched plastic composition is placed In an aqueous solution containing a metal ion salt or a hole sacrificial agent, the photocatalyst exposed on the surface of the plastic composition can reduce the metal ions in the solution to obtain nano-sized metal particles under irradiation with a light source capable of exciting the photocatalyst; Metal electroless plating is performed.

实验结果如下表 1所示。 The experimental results are shown in Table 1 below.
表 1 Table 1
从表 1的测试结果可以看出, 实施例 1〜8与对比例 1〜2比较看出,采用本 发明所提供的技术方案得到的镀件的镀层结合力明显优于现有技术。 As can be seen from the test results of Table 1, the comparison of Examples 1 to 8 with Comparative Examples 1 to 2 shows that the plating adhesion of the plated member obtained by the technical solution provided by the present invention is significantly superior to the prior art.
从实施例 1〜6与实施例 7〜8的结果比较可以看出,采用本发明所提供的方 案即金属离子盐与空穴牺牲剂的质量比为 0.1〜: 100: 1 时, 所得到的镀层结合 力高。 It can be seen from the comparison between the results of Examples 1 to 6 and Examples 7 to 8 that the mass ratio of the metal ion salt to the hole sacrificial agent is 0.1 to: 100:1 by the solution provided by the present invention. The coating has a high bonding strength.
通过比较实验结果发现, 对比例 1中, 由于没有光催化剂的存在, 所以没 有纳米金属的沉积, 化学镀时根本形成不了镀层; 对比例 2中得到的镀件, 除 激光刻蚀的区域有镀层外, 未经激光刻蚀的区域也有镀层存在, 不满足电路板 图案的要求。 因为在激光刻蚀前后, 即使在室温下,银盐也易见光、 受热分解, By comparing the experimental results, it was found that in Comparative Example 1, since there was no photocatalyst, there was no deposition of nano metal, and no plating was formed at the time of electroless plating; the plated part obtained in Comparative Example 2 was coated except for the laser etched region. In addition, the areas not laser etched are also coated, which does not meet the requirements of the board pattern. Because before and after laser etching, even at room temperature, silver salts are easy to see light, decompose by heat,
10 PIDM090739P
使激光未刻蚀区域受到银污染, 最后造成镀件精度很差。 而采用本发明所提供 的技术方案得到的实施例 1~8中镀件 Α1~Α8 , 由于激光未刻蚀区域表面没有 光催化剂的存在, 没有纳米金属粒子的沉积, 故化学镀铜后镀件表面图案清晰 分明, 精度很高。 10 PIDM090739P The unetched areas of the laser are contaminated with silver, which ultimately results in poor precision of the plated parts. In the first to eighth embodiments obtained by the technical solution provided by the present invention, the plating members Α1 to Α8, because there is no photocatalyst on the surface of the laser unetched region, there is no deposition of nano metal particles, so the electroless copper plating after plating The surface pattern is clear and precise.
