Pad Printing Fine Lines for Conductive Inks
At a recent UKDL (UK Displays and Lighting) Metalisation and Dialectrics Conference, a presentation on the Pad Printing Process was given by Kaye Dee Machine Sales Manager Mick Beech. Particular emphasis of the presentation was on how printing very fine details and high resolution graphics can be incorporated into this method of printing. Exploring the various technologies available for printing electrically conductive inks used in the printing of circuits was a key requirement of some of the delegates attending the conference.
Kaye Dee has a long established working relationship with Swansea University and they were recently delighted to receive an order from the Research and Printing Technology Department. The University have purchased a machine from the new Teca Print Servo range – a TPX 300 Controlled Pad Printing machine which will be used to continue their research into the printing of electrically conductive inks and printing fine lines to high tolerances.
The diagram below shows an image from the University’s microscope. The line which is visible was printed at around 50 microns using a Teca Print TPX 100 from an open etch steel plate. Trials were also carried out on double printed lines and it was identified that the TPX machine had a repeatability of 5 microns.
Reto Bianco, Teca Print European Sales Manager said that he was delighted to hear of these excellent results but was not in anyway surprised by them! He believed that it was a reflection of their continual pursuit for excellence which enabled Teca Print Pad Printing equipment to be supplied into a wide range of demanding industrial applications. Contact lens manufacturing and the Swiss Watch Industry are just some examples where a high tolerance printing environment is required and where Teca Print Pad Printing equipment is the obvious choice.
