Abstract

A limiting factor in putting a conductive image on a 3.dimensional surface of a molded part such as a unique concept printed circuit board has been the complex imaging systems needed. For instance holography, multiplane projection or sequential contaot printing are techniques that could achieve image transfer onto a 3-dimensional object. An opto-mechanlcal fixture is described where the image transfer from master image to receiver is made using simple Contact or off contact imaging techniques on a photo sensitive silver salt coated surface or a photo sensitive polymer coated surface.

AUTOMASK: A METHOD TO IMAGE ON A PHOTOSENSITIZED

3-DIMENSIONAL OBJECT

ABSTRACT

  A limiting factor in putting a conductive image on a 3.dimensional surface of a molded part such as a unique concept printed circuit board has been the complex imaging systems needed. For instance holography, multiplane projection or sequential contaot printing are techniques that could achieve image transfer onto a 3-dimensional object. An opto-mechanlcal fixture is described where the image transfer from master image to receiver is made using simple Contact or off contact imaging techniques on a photo sensitive silver salt coated surface or a photo sensitive polymer coated surface.

INTRODUCTION

   During an investigation into ways of putting a conductive image on a 3dimensional object, four techniques were investlgated as to their working feasibility In several environments, i.e. laboratory, engineering prototype and manufacturing. The need for a successful transition to a manufacturing pro- cess was paramount and the severe constraints of a manufacturing process eliminated three of the four imaging systems. The three eliminated were (1) Holography (2) Multiplane projection (3) Sequential Con- tact Printing.

  The fourth system, the opto-mechanical fixture hereafter called Automask proved potentially capable of high productivity In a manufacturing anvlronment due to eimpllcity of concept, ease of operation and adaptability to large matrix imaging without incurring addltlonal high tooling cost.
