Printing electronic circuits on a Flexo press requires a higher degree of precision in applying multiple layers of substrates. Greatest benefits are normally obtained by getting a press equipped with a re-register and servo infeed technique. This truth would look to exclude the owner of a common press from the profits of this sort of perform. However, that is not the case. Printing electronic circuits on a standard Flexo press is achievable with the use of an simply attached servo upgrade such as the Servo 3000 Digital Infeed + Re-register™ system produced by Rotary Technologies. With the Servo 3000 the owner of a normal Flexographic press can enter the profitable higher tech planet of versatile electronic circuits. He can do this for a mere fraction of the cost of a new high finish $ 250,000 to $ 1,000,000 servo press.
Flexible Printed Circuits
The variety of achievable electronic circuit applications for which Flexo printing can be employed incorporate products as straightforward as car seat heaters and rear window defrosters and progress to RFID “chips” as nicely as touch pads and touch screens. By printing electronically conductive inks on a flexible substrate the press can lay down a set of layers of conductors and insulators that are typically sandwiched amongst two “polarizing” layers. The benefit of employing Flexographic printing for creating electronic circuits is that item can be produced by the kilometer. The challenge for printing these circuits is that for the circuit to work the several layers want to be lined up fairly precisely. The a lot more complicated the circuit is the a lot more precise the printing normally wants to be. As the printer progresses to increasingly sophisticated circuits the lines become finer and the spaces between lines turn out to be really narrow. This demands a degree of precision only identified with a precise infeed and re-register program on a servo driven press.
Substrates and Inks for Printing Circuits on a Flexo Press
Commonly employed versatile substrates for printing electronic circuits on a Flexo press incorporate polyester and polyimide films. There are a assortment of electrically conductive inks such as these containing silver or carbon as well as conductive polymers. Which of these is utilised varies with the job.
Getting the Job Right when Printing Electronic Circuits with a Flexo Press
It is essential to bring the press into register in as short a time as attainable when printing electronic circuits. The quickest possible is one length of the press which needs a servo system. When printing a number of layers, it also vital to print at higher resolution. When carrying out this sort of function it is a lot more lucrative to print at full press speed as the profit is in the volume, delivering that waste is controlled. Making use of a servo add on such as the Servo 3000, the technique re-registers the net from the initial pass and makes it possible for the press to print at .0025″ resolution at complete press speed for subsequent passes. This resolution is less than 70 microns and is close to the limit which any Flexo press can acquire right now.
Getting into the World of Electronic Circuits
Investing in the Servo 3000 Digital Infeed + Re-register™ system created by Rotary Technologies will enable the owner of a common Flexo press to enter the world of printing electronic circuits at a fraction of the cost of buying a new high end servo press. These days printers make RFID tags. Learning this technology now will allow the printer to be there with his bags packed when the business gains its “holy grail” of printing functional transistors on a Flexo press.
