DEVICE FOR TRANSFERRING AN IMAGE FROM ACETATE OR ACETATES TO A PHENOLIC PLATE HAVING ONE OR TWO SURFACES

A novel manner for cleanly transferring a circuit printed on a phenolic plate by means of the inventive image transfer device. The present invention is useful for transferring a printed circuit scheme into a phenolic plate using acetate having the image of the printed circuit, said circuit being transferred onto the phenolic plate through a laser printer using controlled and suitable pressure and temperature over the arrangement formed by the phenolic plate and the acetate. It is worthy to mention that the present device is a mechatronic device mechanically formed by a double-frame press, two cold roll steel plates, a millimetre fed screw, a knuckle, two frames and two Teflon coatings; the device is electrically formed by resistances and wiring; electronically is formed by the whole hardware for performing inter-connexions between the resistances, a pyrometer, a continuous current engine, and a PC wherein a Proportional, Integral and Derivative control system (PID) is located, said sy stem using a knowledge base for dynamically adjusting the parameters thereof, regarding the physicochemical properties of the transferring arrangement (acetate-phenolic plate), as well as those of the toner in the fission state acting as a high density liquid, thus providing a higher adherence to the phenolic plate than to the acetate, without distorting the printed circuit. The acetate is removed from the phenolic plate when the arrangement is cooled in a differential manner and the pressure removed. Finally the circuit image is transferred from the acetate to the phenolic plate without suffering any distortion with regard to the original drawing. Una forma novedosa de realizar nítidamente el plasmado de un circuito impreso sobre una placa fenólica es por medio del dispositivo de transferencia de imagen, del cual se trata la presente invención. Para lograr plasmar el esquema del circuito impreso en una placa fenólica por medio de un acetato con la imagen de un circuito impreso realizado a través de una impresora láser hacia la placa fenólica; que con presión y temperatura controladas y adecuadas sobre el conjunto formado por la placa fenólica y el acetato, se logre esta transferencia. Cabe decir, que éste es un dispositivo mecatrónico conformado mecánicamente por una prensa de marco doble, dos placas de acero roladas en frío cold roll, un tornillo con avance milimétrico, una rótula, dos bastidores y dos cubiertas de teflón; eléctricamente conformado por las resistencias y ca
