M3D technology ideal for depositing high precision PTF resistors

Albuquerque, New Mexico 27 April 2006: On May 2nd, Jason Paulson, Optomec Engineer will present a seminar entitled “Maskless Printing of Miniature Polymer Thick Film Resistors for Embedded Applications” at the IPC 3rd International Conference on Embedded Technology in Chelmsford, MA. Mr. Paulsen will explain how the M3D system is an optimal solution for the deposition of high precision PTF resistors. Applications for embedded polymer thick-film (PTF) resistors continue to grow in number, especially in the area of flexible substrates. With the ever increasing complexity of new applications, more advanced processes need to be developed in order to keep up with size, cost, and throughput constraints. This breakthrough approach produces resistors with a variability of better than 10% in the range of 100 – 10k ohms and at a footprint below 0.05mm2. The process involves aerosolizing a PTF paste material and then forming an aerodynamically focused jet of the paste droplets. The droplet stream is deposited at specific locations on a PCB through CAD/CAM control. The CAD/CAM control allows the locations and resistance values to be determined from the CAD file, which eliminates the need for creating screens or stencils and eliminates trimming requirements. Since the M3D system is a CAD driven process, the initial setup costs are lower and design cycle times are reduced. This makes it a cost-effective solution for printing embedded resistors.

Optomec’s M3D system is used in the development and fabrication of next generation microelectronic devices. The M3D system can also be used to repair production defects and legacy electronics, and further has the flexibility to be used for life science and biomedical applications. The functional electronics produced by the M3D system can have line widths and pattern features as small as 10 microns, and as large as 100 microns or more – successfully bridging the gap between existing screen-printing and thin-film lithography capabilities.
