Base materials are the structure components of every flexible circuit being used today. Over the last six decades of flexible circuit innovation, a variety of both dielectric materials and also conductors have actually been employed in the fabrication of flexible circuits. As discussed Flex PCB Technology Past, Present as well as Future, among the earliest descriptions
of just what could be called a flex circuit can be located in a 1903 British patent released to Albert Hansen that described a construction containing level metal conductors on paraffin coated paper. An additional theoretical substrate was the bed linen paper building and construction with patterned circuits of graphite-loaded gum adhesive that Edison described to his then assistant Frank Sprague (later of Sprague Electric popularity), maybe on behalf of several of Sprague’s electric motor concepts. In fact, the disclosure was among many prescient minutes in Edison’s life as an innovator, for it ends up he was not far from future developments in his thinking. Polymer thick movie as well as additive circuits of today fit well under the umbrella of the structures he described more than 100 yeas ago. A lot more just recently, paper has been pointed out yet once more as a substrate for printed electronic devices, a branch of flexible circuits. Chapter 11– Printed Electronics will certainly reveal that the suggestion of printing transistors on paper is much older compared to one might think of and was shown in the 1960s.

While many different products have been tried and also made use of to some degree with time, only a few base products remain in broad use today in flex circuit building and construction. This chapter will certainly analyze those usual materials in addition to some newer selections for flex circuit applications. Nevertheless, it is worth evaluating just what is preferable from a flexible circuit base product to develop a guideline for assumptions.
