Abstract
En este documento se proporcionan dispositivos y métodos para ensamblar contactos eléctricos coplanarios en un conector. En un aspecto, un método ejemplar de ensamble comprende depositar soldadura en un compartimiento de clavija de conector, colocar contactos eléctricos en los depósitos de soldadura, hacer avanzar la barra caliente hacia el compartimiento al contactar cada uno de los contactos eléctricos con el fin de llevar al mismo plano una superficie superior de cada uno de los contactos eléctricos con el compartimiento y fundir la soldadura con la barra caliente calentada para soldar los contactos eléctricos al compartimiento. En un aspecto, un dispositivo de barra caliente ejemplar incluye un imán para acoplar de manera liberable los contactos eléctricos a la barra caliente. En otro aspecto, la barra caliente incluye porciones metálicas para calentar los contactos eléctricos y porciones de cerámica aisladas para contactar el compartimiento. En otro aspecto, una barra caliente eléctricamente conductiva incluye porciones laterales que se extienden lejos de la superficie inferior de calentamiento, lo que facilita un flujo de corriente más uniforme a través de la barra caliente.
