Recent papers and conferences, e.g. Ref. 1, have indicated very strongly that thick film screen processing has become a routine production item, with the specifications and economics being considered in detail. 2The existing resistor and conduction materials and processes have become well documented3,4 and are well known on an international scale. This paper reviews the present situation and, in particular, discusses the effects of a recently-introduced production tool – the laser trimmer.
