    • Methods of forming optical filament circuit patterns with planar and non-planar portions are provided. An optical filament circuit pattern is scribed by moving a filament guide and a substrate relative to one another at a speed between about 110 inches/minute and about 190 inches/minute, and dispensing an optical filament on, or in the vicinity of, a surface of the substrate. The filament or the substrate or both have adhesive surface(s). The adhesive surface is capable of being adhesively actuated by application of energy. Energy is applied simultaneous with, or subsequent to, scribing. Preferably, ultrasound energy is applied having an output power between about 2.0 watts and about 3.5 watts while applying a pressure to the filament between about 1.177 Newtons and about 1.324 Newtons. A portion of the filament circuit pattern is planar and another portion is non-planar. The non-planar portion traverses but does not contact or adhere to a pre-selected area of the substrate. The pre-selected area corresponds with a pad, a contact pattern, a hole, a slot, a raised feature, a part of the previously scribed planar portion of the pattern, and a filament termination point. Alternately, the non-planar portion may be embedded below the surface of the substrate. Another planar portion of the filament circuit traverses the non-planar portion but does not contact or adhere to a pre-selected part of the previously scribed non-planar portion. Optical filament-scribed circuit boards are formed by this method.
    • 提供了形成具有平面和非平面部分的光纤电路图案的方法。 通过以约110英寸/分钟至约190英寸/分钟之间的速度相对于彼此移动细丝引导件和基底来刻划光纤电路图案,并且在表面上或附近分配光纤丝 的基底。 灯丝或基板或两者具有粘合表面。 粘合剂表面能够通过施加能量而被粘合地致动。 能量与划线同时或随后进行。 优选地,施加超声能量,其输出功率在约2.0瓦特至约3.5瓦特之间,同时向约1.177牛顿至约1.324牛顿之间的丝施加压力。 灯丝电路图案的一部分是平面的,另一部分是非平面的。 非平面部分穿过但不接触或粘附到衬底的预选区域。 预选区域对应于垫,接触图案,孔,槽,凸起特征,图案的先前划线的平面部分的一部分以及细丝终止点。 或者,非平面部分可以嵌入在基板的表面下方。 灯丝电路的另一个平面部分穿过非平面部分,但不接触或粘附到先前划线的非平面部分的预选部分。 通过该方法形成光纤丝线电路板。
