El proceso es sencillo y la producci\u00f3n f\u00e1cil, por lo que el coste es bajo.<\/div>\n<h3 data-zone-id=\"0\" data-line-index=\"2\">Agujero ciego (BVH):<\/h3>\n<div data-zone-id=\"0\" data-line-index=\"2\"><b> <\/b> Los agujeros ciegos est\u00e1n situados en las superficies superior e inferior de la placa de circuito impreso y conectan el circuito superficial de la placa con el circuito interior. Se denominan \"agujeros ciegos\" porque no pueden ver el lado opuesto.

Cualquier capa de circuito del interior de la placa de circuito impreso est\u00e1 conectada, pero no conectada a la capa exterior. La producci\u00f3n es dif\u00edcil, por lo que el coste es mucho mayor que el de \"agujero pasante\" y \"agujero ciego\".<\/div>\n<div data-zone-id=\"0\" data-line-index=\"5\"><\/div>\n<h2 data-zone-id=\"0\" data-line-index=\"6\">Reglas de dise\u00f1o para v\u00edas de circuito impreso<\/h2>\n<div data-zone-id=\"0\" data-line-index=\"7\">1.

Para el dise\u00f1o de placas de circuito impreso de 1-4 capas, generalmente se prefieren orificios pasantes de 0,36 mm\/0,61 mm\/1,02 mm (zona de perforaci\u00f3n\/placa\/aislamiento de potencia). Algunos requisitos especiales para cables de se\u00f1al (como cables de alimentaci\u00f3n, cables de tierra y cables de reloj) pueden seleccionarse orificios pasantes de 0,41 mm, 0,81 mm o 1,32 mm, u otros tama\u00f1os seg\u00fan sea necesario.<\/div>\n<div class=\"row\"  id=\"row-783988154\">\n\n\t<div id=\"col-246198107\" class=\"col medium-6 small-12 large-6\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\t<div class=\"img has-hover x md-x lg-x y md-y lg-y\" id=\"image_1127218940\">\n\t\t\t\t\t\t\t\t<div class=\"img-inner dark\" >\n\t\t\t<img decoding=\"async\" width=\"790\" height=\"678\" src=\"https:\/\/uetpcb.com\/wp-content\/uploads\/2021\/08\/pcb-2.png\" class=\"attachment-large size-large\" alt=\"pcb\" srcset=\"https:\/\/uetpcb.com\/wp-content\/uploads\/2021\/08\/pcb-2.png 790w, https:\/\/uetpcb.com\/wp-content\/uploads\/2021\/08\/pcb-2-300x257.png 300w, https:\/\/uetpcb.com\/wp-content\/uploads\/2021\/08\/pcb-2-768x659.png 768w\" sizes=\"(max-width: 790px) 100vw, 790px\" \/>\t\t\t\t\t\t\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\n<style>\n#image_1127218940 {\n  width: 100%;\n}\n<\/style>\n\t<\/div>\n\t\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n<\/div>\n<h2 data-zone-id=\"0\" data-line-index=\"0\"><b>V\u00edas en placas de circuito impreso de alta velocidad<\/b><\/h2>\n<div data-zone-id=\"0\" data-line-index=\"1\">En las placas de circuito impreso y multicapa de alta velocidad, la conexi\u00f3n de las se\u00f1ales tambi\u00e9n debe transmitirse de una interconexi\u00f3n a otra a trav\u00e9s de orificios.<\/div>\n<div data-zone-id=\"0\" data-line-index=\"2\">1.
