<p>Circuits printed on the underside of a thin, flexible, transparent, insulating film are released from those on a rigid carrier below the film using a plate moveable parallel to and on one side of I.R. radiation concentration tone of an approx. hemi-ellipsoidal right section cylindrical reflector. The radiation source is placed at the nearest focus of the reflector and the film is placed at the second focus so that it lies between the source and the rigid carrier. The plate is sprung so that it removes the soldered part of teh film from the carrier on irradiation. The appts. is light and portable.</p> |
