Abstract

La presente divulgación proporciona un conjunto de matriz que tiene un conjunto de salida. El conjunto de salida incluye la primera y segunda placa de salida, en donde cada placa tiene una cara interna respectiva. La primera cara interna está espejada con respecto a la segunda cara interna a lo largo de un eje de simetría. La primera cara interna y la segunda cara interna forman en conjunto una salida alargada a través de la que una película microcapilar sale del conjunto de matriz. Cada cara interna tiene dos superficies estrechas que se extienden en direcciones opuestas alejándose de un punto medio. Para cada cara interna respectiva, un segmento medio (Ms) se extiende entre el punto medio y el eje de simetría, y un segmento pico (Ps) se extiende entre un punto pico y el eje de simetría. El segmento medio (Ms) y el segmento pico (Ps) tienen, cada uno, una longitud. La longitud del segmento medio (Ms) es menor que la longitud del segmento pico (Ps).
