Description
本发明涉及镀膜领域,进一步涉及一镀膜方法及其膜层和镀膜夹具及其应用。
随着电子产品的发展,电子产品的抗摔次数、防刮性、耐磨性、散热性、防水性、耐腐性等性能指标是在激烈的市场竞争中能否取得优势的重要因素。通过对电子产品进行表面改性,尤其是利用化学气相镀膜工艺在产品表面形成很薄的防护涂层是提高上述各项性能的重要手段。例如,通过真空镀膜工艺在所述电子设备的表面镀上一层防水膜或者防水纳米膜层,可有效地提高所述电子产品的防水性能、耐水下通电性能,近几年这种技术已经逐渐推广应用于防水手表或者防水手机等电子产品中。当经过上述镀膜处理后的防水电子产品被浸入水中时,防水膜或者防水纳米膜层能够有效地防止电子产品的电路或者外部接口如USB端口、充电端口等因进水发生短路,并防止水分腐蚀防水电子产品的电路板或者电子元件等。
然而,电路板上的一些电子元件,如转接器、USB插座等电路接口元件,在对其进行镀膜防护时,若其表面所镀的防水膜较厚,则由于膜层一般为绝缘的高分子材料,导致电路接口元件的数据传输、电子信号发射等重要功能大幅下降,造成OTG(On-The-Go)测试失败。因此,这些器件表面的膜层对其厚度上限要求较为严格。同一块电路板上的转接器和USB插座表面的防水膜的厚度一般小于电路板的主板表面其他部位膜层的厚度。
目前为达到不同区域具有不同膜层厚度的效果,采取的技术手段主要是先对电路接口元件或者其他特殊区域进行贴纸或者涂上树脂胶、可剥胶等遮蔽预处理,镀膜过程则分两次进行,1)将转接器部位遮蔽后,进行第一次镀膜,所镀的膜厚度较大,满足主板上需重点防护器件的要求;2)去除遮蔽,进行第二次镀膜处,满足电路接口元件导通性要求。遮蔽、去遮蔽这一过程往往是由人工进行的, 这导致人工成本的上升和镀膜时间的延长,使镀膜过程的经济成本大幅上升,量产性下降。
近年来,镀膜技术的快速发展,尤其是气相沉积技术日臻成熟,使利用表面镀膜技术提高电子产品的性能成为一种技术热点。表面镀膜技术可赋予电子产品,诸如高的抗摔次数,优异的防刮耐磨性、良好的散热性、防水性、耐水下通电性以及耐腐性等性能。等离子体化学气相沉积技术是目前常用的镀膜技术,在电场作用下产生等离子体,借助等离子体使含有膜层组成原子的气态物质发生化学反应,在产品表面沉积防护膜层。
然而,针对表面具有天线弹片、感应器、摄像模组、声学器件和USB接口等多个电子元件的基材,在镀膜防护时,需要根据不同电子器件的特性进行选择性镀膜。比如,要求低阻抗的电子元件完全不能被镀膜,或者不能镀较厚的膜。由于化学气相沉积法中成膜原料为气相状态,气相涂层材料会在所有放置于其中可与成膜材料接触的元器件表面沉积成膜。当对集成了多个元器件的PCB进行镀膜时,为控制特殊器件的涂层厚度,该类电子元件需要被遮蔽,使其表面无法形成涂层,而PCB其他未被遮蔽的部位表面依然能够形成防护涂层。例如,天线弹片被镀膜后,形成薄膜的阻抗会改变天线的射频性能;光学器件被镀膜后,形成薄膜即使很透明也会改变光学器件的透射效果;声学器件被镀膜后,形成薄膜即使很薄也会影响声学器件振膜的振动而改变声学效果。选择合适的遮蔽方式以满足所述基材的镀膜需求是镀膜技术的一个难点。
目前满足上述基材选择性镀膜常用的遮蔽方式是点胶和贴纸。在镀膜防护前,对电子元件表面或接口等特殊遮蔽区域进行点胶或贴纸处理,镀膜结束后,剥离遮蔽的树脂胶或撕下贴纸。这种遮蔽方式无疑会造成:(1)在去除遮蔽时,造成电子元件的二次损伤,影响其性能;(2)遮蔽、去遮蔽这一过程往往是由人工进行的,这导致人工成本的上升和镀膜时间的延长,严重影响镀膜效率;(3)遮蔽所用的树脂胶和贴纸无法循环使用,使镀膜过程的经济成本大幅上升,对技术要求较高,无法实现大批量生产。

在本实施例中,所述镀膜夹具110的所述夹具主体110和所述遮蔽件120均能够被循环多次地拆卸与安装,从而使多个数量的所述基材1600均能够循环地安装于所述镀膜夹具110,并实现统一化镀膜,而且不需要每次镀膜更换新的贴纸,节省成本,而且被镀于各所述基材1600表面的所述膜层1700的形状规格基本保持统一,提高生产效率,满足规格化量产需求,同时成本较低,耐用性较高,具有循环利用性。
如图8所示,进一步地,所述镀膜方法还包括步骤:
S30、藉由所述第二基材1602被安装于所述镀膜夹具1100并被置入所述镀膜设备1500的所述镀膜腔1510内进行镀膜,形成所述第二膜层1702于所述第二基材1602表面未被所述镀膜夹具1100遮蔽的电子元件或者位置,和形成至少一第二无膜层区域1720于所述第二基材1602表面被所述镀膜夹具1100遮蔽的电子元件或者位置,其中所述第二基材1602表面被所述镀膜夹具1100遮蔽的电子元件或者位置未形成所述第二膜层1702;和
S40、藉由所述第二基材1602被拆卸于所述镀膜夹具1100,暴露所述第二基材1602表面未形成所述第二膜层1702的电子元件或者位置于所述第二无膜层区域1702,以保证所述第二基材1602的所述电子元件的正常工作性能。
可以理解的是,所述第一基材和所述第二基材分别依次被安装于同一所述镀膜夹具1100后被置入所述镀膜设备1500的所述镀膜腔1510进行镀膜,其中所述第一基材和所述第二基材的形状尺寸基本保持一致,即所述第一基材和所述第二基材均适配地安装于所述镀膜夹具1100,且所述第一基材和所述第二基材分 别被所述镀膜夹具1100遮蔽的位置基本保持一致,以使在镀膜时,所述第一基材和所述第二基材能够在相同的位置被镀上所述膜层1700。也就是说,所述第一膜层1701与所述第二膜层1702的形状大小基本保持一致,相应地,所述第一无膜层区域1701和所述第二无膜层区域1702的形状大小、数量以及位置也基本相同。
需要指出的是,所述第一膜层与所述第二膜层的材料或厚度可以相同或者不同。也就是说,在镀膜工艺中,当被充入所述镀膜设备1500的所述镀膜腔1510内的材料的种类或数量的不同或者所述镀膜设备1500的镀膜时间、电压或者其他参数的不同时,在所述第一基材表面形成的所述第一膜层与所述第二基材表面的所述第二膜层的材料或者厚度也不相同。当被充入所述镀膜设备1500的所述镀膜腔1510内的材料的种类和数量、镀膜时间以及其他参数均相同时,所述第一膜层与所述第二膜层的材料和厚度基本能够保持一致,从而实现统一化。

具体地,在所述步骤S10中,所述第一膜层1701被形成于所述第一基材1601表面的所述第一部件1604,在所述步骤S20中,其中所述第一无膜层区域1710被形成于所述第一基材1601的所述无需镀膜位置1603。进一步地,所述第一无膜层区域1710包括但不限于孔型或者槽型的区域,以适配于所述第一基材1600的所述无需镀膜位置1603的形状或者结构等。

在镀膜时,由于所述第一无膜层区域1710和所述第二无膜层区域1720分别由所述基材1600的所述无需镀膜位置1603被所述镀膜夹具1100的所述遮蔽件 120遮挡而无法镀上所述膜层1700而形成,因此,各所述无膜层区域(所述第一无膜层区域1710或所述第二无膜层区域1720)分别与对应的所述遮蔽件120的遮蔽面的形状或者数量相一致,其中多个所述第一无膜层区域1710或者多个所述第二无膜层区域1720的数量或者形状分别对应于多个所述无需镀膜位置1603的数量或者形状。
例如,所述遮蔽件120的遮蔽面的形状为圆形,则所述无膜层区域(所述第一无膜层区域1710或所述第二无膜层区域1720)的形状也为大小相同的圆形。或者所述遮蔽件120的遮蔽面的形状也可以为方形、三角形、四边形、多边形或者不规则形状等,其中所述无膜层区域(所述第一无膜层区域1710或所述第二无膜层区域1720)相应地与所述遮蔽件120的遮蔽面的形状大小相同。
如图5和图6所示,换句话说,所述膜层1700具有至少一膜层孔1730,其中所述膜层1700被镀于所述基材1600的所述第一部件1604,其中所述膜层孔1730位于所述基材1600的所述无需镀膜位置1603并形成所述无膜层区域(所述第一无膜层区域1710和所述第二无膜层区域1720)。可选地,所述膜层孔1730包括但不限于环形孔或者边缘孔,其中所述环形孔的周围由所述膜层1700全包围,其中所述环形孔如圆形孔、方形孔或者不规则孔等,其中所述边缘孔位于所述膜层1700的边缘,其中所述边缘孔如半环形孔、弧形孔、半圆孔等。
当所述膜层1700被镀于所述基材1600的所述第一部件1604时,所述基材1600的所述无需镀膜位置1603位于所述膜层孔1730的底部并与所述膜层孔1730形成一槽型结构。当然,由于所述膜层1700的厚度为纳米级的,所述膜层孔1730的深度也为纳米级的,因此,所述槽型结构一般情况下人的手部感官基本上无法触摸感受到。
如图4至图9所示,进一步地,本优选实施例还提供了利用所述镀膜方法制备而成的所述膜层1700,其中所述膜层1700具有所述膜层孔1730,其中所述膜层1700被镀于所述基材1600的表面,其中所述膜层孔1730位于所述基材1600的所述无需镀膜位置1603并形成所述无膜层区域(所述第一无膜层区域1710和所述第二无膜层区域1720)。优选地,所述膜层1700包括形成于所述基材1600的所述第一部件1604的表面的至少一较厚膜层17012和形成于所述基材1600的所述第二部件1605的表面的至少一较薄膜层17011,其中所述较厚膜层17012的厚度大于所述较薄膜层17011的厚度。
如图3所示,更具体地,所述夹具主体110包括一第一主体111和一第二主体112,其中所述第一主体111和所述第二主体112被可打开地安装在一起如卡合连接,并在所述第一主体111和所述第二主体112之间形成所述安装腔1102,以便于安装所述基材1600。优选地,所述夹具主体110的两侧均具有所述裸露孔1101,具体地,所述裸露孔1101包括至少一第一裸露孔11011和至少一第二裸露孔11012,其中所述第一裸露孔11011被开设于所述第一主体111并与所述安装腔1102相连通,其中所述第二裸露孔11012被开设于所述第二主体112并与所述安装腔1102相连通。因此,在安装所述基材1600于所述夹具主体110的所述安装腔1102后,所述基材1600的一侧的部分被暴露于所述第一裸露孔11011,另一侧的部分被暴露于所述第二裸露孔11012,使得所述基材1600的两侧的被裸露的部分均能够被镀膜或者同时镀膜。
相应地,所述遮蔽件120包括至少一第一遮蔽件121和至少一第二遮蔽件122,其中所述第一遮蔽件121被设置于所述第一主体111与所述基材1600的一侧之间并用于对应地遮蔽所述基材1600的所述侧表面的无需镀膜的所述电子元件1610,其中所述第二遮蔽件122被设置于所述第二主体112与所述基材1600的另一侧之间并用于对应地遮蔽所述基材1600的所述另一侧表面的无需镀膜的所述电子元件1610,从而满足所述基材1600的两侧同时镀膜的需求,且保证所述基材1600两侧表面的无需镀膜的所述电子元件1610均无法被镀上所述膜或者膜层。
值得一提的是,所述第一遮蔽件121与所述第二遮蔽件122能够相互配合地对所述基材1600表面的同一电子元件1610进行遮蔽,如位于所述基材1600的侧边的所述电子元件1610,在此不受限制。
可选地,所述夹具主体110也可以仅在其中一侧开设所述裸露孔1101,使得所述基材1600的相应的一侧能够被镀膜,适用于所述基材1600仅在一侧镀膜的情况。或者,在所述基材1600的一侧被镀膜完毕后,所述基材1600反装于所述夹具主体110的所述安装腔1102,并再次进行镀膜,使得所述基材1600的另一侧也被镀膜,从而满足所述基材1600在两侧均被镀膜的需求。
可选地,当所述基材1600仅有一侧表面具有无需镀膜的所述电子元件1600时,所述第一遮蔽件121被实施为设置于所述第一主体111与所述基材1600的所述侧之间并用于遮蔽所述基材1600的所述侧表面的无需镀膜的所述电子元件 1610,而所述第二主体111与所述基材1600的另一侧之间可以无需设置所述第二遮蔽件122,或者所述第二遮蔽件122并未遮蔽所述基材1600的所述另一侧表面的需要被镀膜的部位或者电子元件,从而实现所述基材1600的镀膜需求。
优选地,所述夹具主体110的所述第一主体111和所述第二主体112均由硬质材料制成,如金属材料,其中所述第一主体111和所述第二主体112具有较强的硬度,不易弯曲变形,其中所述第一主体111与所述第二主体112相互卡合固定,其中所述基材1600被收纳于所述第一主体111与所述第二主体112之间的所述安装腔1102,从而保护所述基材1600不易弯曲受损,防止所述基材1600在外力冲击下而变形或者损坏等。
优选地,所述遮蔽件120的所述第一遮蔽件121和所述第二遮蔽件122均由柔性材料制成,如硅胶材料,其中所述第一遮蔽件121和所述第二遮蔽件122被分别设置于所述基材1600的两侧并由所述夹具主体110的所述第一主体111和所述第二主体112夹持固定,从而起到缓冲保护所述基材1600的作用,同时保持所述基材1600在镀膜时的相对稳定性,防止所述基材1600在镀膜过程中发生相对偏移或者晃动等,且不易损伤所述基材1600,以保证镀膜可靠性。也就是说,所述第一遮蔽件121在所述第一主体111和所述基材1600之间进一步地起到缓冲保护作用,其中所述第二遮蔽件122在所述第二主体112和所述基材1600之间进一步地起到了缓冲保护作用,即所述第一遮蔽件121和所述第二遮蔽件122在所述基材1600的两侧在起到遮蔽作用的同时保护所述基材1600不易受到损伤。
值得一提的是,所述遮蔽件120的所述第一遮蔽件121和所述第二遮蔽件122分别与所述基材1600的表面平整地贴合,其中所述夹具主体110的所述第一主体111与所述第一遮蔽件121平整地贴合,其中所述第二主体112与所述第二遮蔽件122平整地贴合,从而保证所述基材1600整体受力均匀,防止应力集中,从而防止所述基材1600弯曲或者损坏等。进一步地,所述夹具主体110的两侧表面平整,使得所述夹具主体110被放置于所述镀膜设备的真空镀膜腔内时能够保持平稳,同时保证所述基材1600平稳,不易晃动而影响镀膜等。
由此可见,所述镀膜夹具110的所述夹具主体110和所述遮蔽件120均能够被循环多次地拆卸与安装,从而使多个数量的所述基材1600均能够循环地安装于所述镀膜夹具110,并实现镀膜,而不需要每次镀膜更换新的贴纸,节省成本, 而且在镀膜后不会影响所述电子元件1610的性能,提高生产效率,满足大批量生产需求,同时成本较低,耐用性较高,具有循环利用性。
如图4和图9所示,进一步地,所述基材1600表面还包括至少一第二部件1605,其中所述第二部件1605包括至少一需镀较薄膜的电子元件例如电路接口元件如转接器、USB接口等。进一步地,所述膜层1700(所述第一膜层1701或所述第二膜层1702)包括一体连接的所述较薄膜层17011和所述较厚膜层17012(以所述第一膜层1701为例),其中所述较薄膜层17011被镀于所述基材1600的所述第二部件1605。换句话说,所述较薄膜层17011的厚度小于所述第一膜层1701的所述较厚膜层17012的厚度,即所述第二部件1605表面的所述较薄膜层17011的厚度小于所述第一部件1604表面的所述较厚膜层17012的厚度。进一步地,为了不影响所述第二部件1605如所述电路接口元件的电连接性能,在所述第二部件1605的表面制备的所述较薄膜层17011的厚度在预设范围内。
进一步地,所述基材1600表面的所述电子元件1610选自一组:至少一需镀膜电子元件1611、至少一无需镀膜电子元件1612、至少一部分镀膜电子元件1613以及至少一镀较薄膜电子元件1614中的其中一种或者多种组合。也就是说,其中所述需镀膜电子元件1611和所述部分镀膜电子元件1613的需镀膜部分16131均位于所述第一部件1604以被镀上所述较厚膜层17012,其中所述无需镀膜电子元件1612和所述部分镀膜电子元件1613的无需镀膜部分16132均位于所述无需镀膜位置1603,其中所述镀较薄膜电子元件1614位于所述第二部件1605以被镀上所述较薄膜层17011。
进一步地,所述遮蔽件120进一步包括至少一遮蔽主体1210(所述遮蔽主体1210优选地包括至少一第一遮蔽主体1211和至少一第二遮蔽主体1212),其中所述第一遮蔽件121包括所述第一遮蔽主体1211,其中所述第二遮蔽件122包括所述第二遮蔽主体1212,其中所述遮蔽件120的所述第一遮蔽件121和所述第二遮蔽件122进一步地分别包括选自一组:至少一完全遮蔽部123、至少一部分遮蔽部124以及至少一悬空遮蔽部125中的其中一种或者多种组合,其中所述完全遮蔽部123用于相适配地覆盖或者包裹于所述无需镀膜位置1603的所述无需镀膜电子元件1612以实现完全遮蔽,其中所述部分遮蔽部124用于相适配地覆盖或者包裹于所述部分镀膜电子元件1613的所述无需镀膜部分16132以实现部分遮蔽,其中所述悬空遮蔽部125用于与所述第二部件1605的所述镀较薄膜 电子元件1614之间保持所述镀膜空隙D1以形成悬空遮蔽,从而在所述镀较薄膜电子元件1614的表面镀上所述较薄膜层17011。
可以理解的是,针对于不同类型的所述基材1600,所述遮蔽件120能够被预设为具有所述完全遮蔽部123、所述部分遮蔽部124以及所述悬空遮蔽部125中的一种或者多种的组合的结构。或者说,若所述基材1600仅包括所述无需镀膜电子元件1612和所述需镀膜电子元件1611,则所述遮蔽件120被预设为具有所述完全遮蔽部123,而可以具有或者不具有所述部分遮蔽部124和所述悬空遮蔽部125。也就是说,所述遮蔽件120的结构能够根据所述基材1600的类型型号进行预设,在此不受限制。
在本实施例中,所述完全遮蔽部123、所述部分遮蔽部124以及所述悬空遮蔽部125被一体连接,其中所述遮蔽件120的所述完全遮蔽部123与所述基材1600的所述无需镀膜电子元件1612的位置相对应,其中所述部分遮蔽部124与所述基材1600的所述部分镀膜电子元件1613的所述无需镀膜部分16132的位置相对应,其中所述悬空遮蔽部125与所述基材1600的所述镀较薄膜电子元件1614的位置相对应。也就是说,所述镀膜夹具1100的所述遮蔽件120能够整体地同时对多个所述不需要镀膜的所述电子元件1610进行遮蔽,而其他需要镀膜的所述电子元件1610并未被遮蔽,从而满足镀膜需求。
具体地,所述第一遮蔽件121具有所述第一遮蔽主体1211,其中所述第一遮蔽主体1211形成所述第一通孔12011,其中所述完全遮蔽部123、所述部分遮蔽部124以及所述悬空遮蔽部125被一体成型于所述第一遮蔽主体1211。所述第二遮蔽件122具有所述第二遮蔽主体1221,其中所述第二遮蔽主体1221形成所述第二通孔12012,其中所述完全遮蔽部123、所述部分遮蔽部124以及所述悬空遮蔽部125被一体成型于所述第二遮蔽主体1221。
也就是说,在安装所述基材1600于所述镀膜夹具1100的所述安装腔1102时,所述完全遮蔽部123恰好对应覆盖或者包裹于所述无需镀膜电子元件1612,所述部分遮蔽部124恰好对应包裹或者覆盖于所述部分镀膜电子元件1613的所述无需镀膜部分16132,所述悬空遮蔽部125恰好对应与所述镀较薄膜电子元件1614之间保持所述镀膜空隙D1。
在镀膜时,由于所述需镀膜电子元件1611和所述部分镀膜电子元件1613的所述需镀膜部分16131均未被所述遮蔽件120遮挡,因此所述需镀膜电子元件 1611和所述部分镀膜电子元件1613的所述需镀膜部分16131均会沉积一定数量的等离子体从而形成一定厚度的所述较厚膜层17012。而所述无需镀膜电子元件1612和所述部分镀膜电子元件1613的所述无需镀膜部分16132均被遮挡,而导致无法沉积等离子体,从而无法在表面形成镀膜或者膜层。而所述悬空遮蔽部125悬空于所述镀较薄膜电子元件1614的上侧并与所述镀较薄膜电子元件1614之间具有一定间距的所述镀膜空隙D1,使得所述悬空遮蔽部125会降低所述等离子体沉积于所述镀较薄膜电子元件1614表面的速率,从而导致所述镀较薄膜电子元件1614的表面被镀膜的厚度降低,即形成所述较薄膜层17011,并根据预先设定所述镀膜空隙的间距大小,从而实现镀不同厚度的所述较薄膜层17011。
值得一提的是,通过预设所述镀膜空隙D1的高度,相应地改变所述等离子体沉积于所述镀较薄膜电子元件1614表面的沉积速率,从而使所述镀较薄膜电子元件1614的表面被镀上预设厚度的所述较薄膜层17011。相应地,对于多个所述镀较薄膜电子元件1614,各所述镀较薄膜电子元件1614分别与所述遮蔽件120的多个所述悬空遮蔽部125之间的对应的所述镀膜空隙D1能够分别被预设,使得所述镀膜设备通过一次镀膜就能够满足分别对所述基材1600表面的多个所述电子元件1610的不同厚度的镀膜需求,降低镀膜次数,节省人力和时间,提高镀膜效率,延长镀膜设备的使用寿命。
在本实施例中,所述遮蔽件120的所述完全遮蔽部123与所述基材1600的无需镀膜位置1603之间的间距在0-1mm之间,在镀膜过程中,所述完全遮蔽部123与所述无需镀膜位置1603之间可以容许有部分渗透的缝隙,但是并不会影响所述无需镀膜位置1603上的电子元件的性能。相应地,为了不影响所述电路接口元件的电连接性能,所述较薄膜层17011的厚度应不大于250nm。可选地,当所述遮蔽件120的所述悬空遮蔽部125与所述基材1600的所述第二部件1605的所述镀较薄膜电子元件1614之间的所述镀膜空隙D1为0.5mm时,所述基材1600的电路接口元件如USB接口与所述悬空遮蔽部125之间的镀膜厚度即所述较薄膜层17011的厚度可优选地控制在50nm~150nm之间。或者所述镀膜空隙D1在0.2-0.8mm范围以内。所述基材1600的所述第一部件1604的上侧可以不被所述遮蔽件120遮蔽,可选地,所述第一部件1604的上侧镀膜厚度即所述较厚膜层17012的厚度一般在250-1000nm之间,优选地在350nm~400nm之间,如此,所述第一部件1604的表面仍然能够被制备所需厚度的薄膜。熟知本领域 的人员应当理解,上述这些数据范围仅作为本实施例的举例说明,并不会对本发明造成限制。
相应地,在所述步骤S10中,包括步骤:
S11、形成所述较厚膜层17012于所述基材1600的所述第一部件1604,其中所述基材1600的所述无需镀膜位置1603被所述基材1600遮蔽而未形成所述膜层1700。
在所述步骤S11中,所述第一部件1604未被所述镀膜夹具1100遮蔽,其中所述无需镀膜位置1603被所述镀膜夹具1100的所述遮蔽件120完全遮蔽。

在所述步骤S50执行结束,即第一次镀膜结束后,工作人员需将所述基材1600和所述镀膜夹具1100从所述镀膜腔1100内取出,然后去掉用于遮蔽所述第一部件1604的所述镀膜夹具1100的所述完全遮蔽部123,然后再次放入所述镀膜腔1100内进行第二次镀膜,即执行所述步骤S60。在所述步骤S60结束后,工作人员需将所述基材1600和所述镀膜夹具1100取出并拆卸,即获得最终的镀膜产品。
也就是说,所述第一膜层170121与所述第二膜层170122层叠的部分形成所述较厚膜层17012,其中所述第一膜层170121与所述第二膜层170122未层叠的部分形成所述较薄膜层17011。
可以理解的是,根据分别对所述步骤S50和步骤S60中的镀膜设备的参数或者反应原料的设置,所述第一膜层170121和所述第二膜层170122的材料与厚度能够分别被预设为相同的或者不同的材料或者厚度,在此不受限制。

在本实施例中,所述完全遮蔽部223、所述部分遮蔽部224以及所述悬空遮蔽部225被一体连接,其中所述遮蔽件220的所述完全遮蔽部223与所述基材2600的所述无需镀膜电子元件2612的位置相对应,其中所述部分遮蔽部224与所述基材2600的所述部分镀膜电子元件2613的所述无需镀膜部分26132的位置相对应,其中所述悬空遮蔽部225与所述基材2600的所述镀较薄膜电子元件2614 的位置相对应。也就是说,所述镀膜夹具2100的所述遮蔽件220能够整体地同时对多个所述不需要镀膜的所述电子元件2610进行遮蔽,而其他需要镀膜的所述电子元件2610并未被遮蔽,从而满足镀膜需求。

在镀膜时,由于所述需镀膜电子元件2611和所述部分镀膜电子元件2613的所述需镀膜部分26131均未被所述遮蔽件220遮挡,因此所述需镀膜电子元件2611和所述部分镀膜电子元件2613的所述需镀膜部分26131均会沉积一定数量的等离子体从而形成一定厚度的镀膜。而所述无需镀膜电子元件2612和所述部分镀膜电子元件2613的所述无需镀膜部分26132均被遮挡,而导致无法沉积等离子体,从而无法在表面形成镀膜。而所述悬空遮蔽部225悬空于所述镀较薄膜电子元件2614的上侧并与所述镀较薄膜电子元件2614之间具有一定间距的所述镀膜空隙D1,使得所述悬空遮蔽部225会降低所述等离子体沉积于所述镀较薄膜电子元件2614表面的速率,从而导致所述镀较薄膜电子元件2614的表面被镀膜的厚度降低,并根据预先设定所述镀膜空隙的间距大小,从而实现镀不同厚度的薄膜。
值得一提的是,通过预设所述镀膜间隙D的高度,相应地改变所述等离子体沉积于所述镀较薄膜电子元件2614表面的沉积速率,从而使所述镀较薄膜电子元件2614的表面被镀上预设厚度的镀膜。相应地,对于多个所述镀较薄膜电子元件2614,各所述镀较薄膜电子元件2614分别与所述遮蔽件220的多个所述悬空遮蔽部225之间的对应的所述镀膜间隙D能够分别被预设,使得所述镀膜设 备通过一次镀膜就能够满足分别对所述基材2600表面的多个所述电子元件2610的不同厚度的镀膜需求,降低镀膜次数,节省人力和时间,提高镀膜效率,延长镀膜设备的使用寿命。
