[0074] Laser Direct Structuring制程主要有四步骤
[0075] 1) 射出成型 (Injection molding^ 此步骤在热塑性的塑料上射出成型。
[0076] 2) 雷射活化(LaSer ACtivati0n)。 此步骤透过雷射光束活化, 藉由添加特殊化学 剂雷射活化使物体产生物理化学反应行成金属核, 除了活化并形成粗糙的表面
, 使铜在金属化过程中在塑料上扎根。
[0077] 3) 电镀(Metallization^ 此为 LDS制程中的清洁步骤, 在仅用作电极的金属化 塑胶表面进行电镀 5~8微米的电路, 如铜、 镍等, 使塑料成为一个具备导电线路 的 MID元件。
[0078] 2. 在 PCB板上的环形天线(loop antenna, 导电环)。 环形天线是将一根金属导 线绕成一定形状, 如圆形、 方形、 三角形等, 以导体两端作为输出端的结构。 根据环形天线的周长 L相对与波长 λ的大小, 环形天线可分为电大环 (L≥ ) 、 中 等环 (λ/4≤ί≤λ) 和电小环 (Ι λ/4) 三类。 本申请例如可以为电小环天线, 电 小环上的电流近似按等幅同相分布。
[0079] 3. 标签芯片、

[0083] 绑定过程具体包括:
[0084] 1、 准备好需要的带有环形天线的 PCB板。 [0085] 2、 在 PCB板上放芯片的位置使用滴胶机滴胶, 准备固定芯片。
[0086] 3、 使用绑定机, 将芯片从 wafer上取下, 并通过绑定机的吸嘴将芯片放置在滴 胶的位置, 芯片引脚朝上。
[0087] 4、 将放置好芯片的 PCB板放在烤箱中, 烤温度范围为 60-120摄氏度, 吋间范围 为 10-55分钟, 使胶体固化, 标签芯片粘结稳定。
[0088] 5、 通过绑定机, 将金线的一端焊接在标签芯片的一个引脚上, 另一端焊接在 环形天线端口的一侧, 使用另一根金线, 将芯片的另一个引脚和天线端口的另 外一侧焊接在一起。
[0089] 6、 使用滴胶机在芯片和金线的位置滴环氧树脂胶。
[0090] 7、 将滴好环氧树脂胶的 PCB板放在烤箱中, 烤温度范围为 120-200摄氏度, 吋 间范围为 30-65分钟。
[0091] 8、 烤完之后, 取出 PCB板, 绑定工艺完成。

[0093] 1、 导电布, 是在普通布质材料中沁入了金属导电颗粒的一种具有导电特性的 布匹。 这种布匹可以分为棉布、 尼龙布等, 可以根据实际的需要进行制造和生 产。
[0094] 2、 导线纤维, 是一种具有导电特性的碳纤维材质构成的编织材料, 其具有类 似于金属的导线特定, 同吋具有碳纤维的柔韧性。
[0095] 3、 印刷导电材质, 是将导电颗粒如银粉、 铝粉等与玻璃粉、 环氧树脂等按比 例混合而成的一种可以通过丝网进行印刷的胶状材质。
[0096] 复合好的导电布和胶体通过模切(die-cut)工艺做成需要的天线形状。 依据不同 需求, 天线尺寸与形状会有所差异, 图 9示出了一种形状的耦合天线。
[0097] 模切工艺包括:
[0098] 1、 层合好的导电布和胶体与普通的硅油纸进行层合, 硅油纸即为底纸。
[0099] 2、 根据需要, 制作模切的模具, 并将模具安装在模切机器上。
[0100] 3、 将层合好的导电布安装在模切机器上, 进行模切操作。
[0101] 4、 模切完成之后, 底纸保留, 剩余的导电布进行排废操作。 [0102] 服装电子标签制作步骤包括:
[0103] 1、 将卷状基片放置在热压机器的卷轴上。 热压机器为对物体进行加热加压的 设备, 分为底板和压板, 底板不动, 压板可以上下活动, 底板和压板上都可以 加温。 底板的尺寸不小于 30cm*30cm, 加热温度范围为 90至 180摄氏度, 吋间范 围为 5至 120秒。
[0104] 2、 通过机器将模切好的带有胶体的耦合天线放置在基片的指定位置上。 在布 质基材上, 通过编制或者印刷工艺, 可以在布质基材上留下条状、 点状, 或是 穿孔方式的标识, 利用吸嘴将模切好的天线吸住, 并以标识线 /点为基淮, 将天 线放置在标识线处。
[0105] 3、 通过机器将 RFID单元放置在距离耦合天线一定的位置处, 该位置为指定好 的位置。 RFID单元按照规定放置在距离天线指定的位置, 以天线上的某一个具 体位置为参考。 参见图 11。
