INTRODUCTION The printing for hybrid circuits is a fundamental process in which the conductors resistors and overglaze are put onto a ceramic tile called a substrate While conductors resistors and overglaze are not printed at the same time the process is the same Thus it is very important that anyone who is in the microelectronics field should know the basic process While the process may change depending on technology used the same basic principles will remain RESOURCES The printing process requires a few resources First the process requires a clean room Second it requires a hybrid printer Third it requires a prepared screen of emulsion with the circuit image on it Finally when printing is done you will need a dryer and a furnace For materials the printing process requires a paste Depending on whether you are printing a conductor resistor or the overglaze layers dictates which paste to use PROCESS Once the screen is mounted properly in the printer the printing process may begin The spacing between the screen and the substrate is an important element and should be set to the printers specifications The reason for the emphasis on spacing is because if the screen is not properly spaced the paste will not peel nicely from the screen Once the spacing is checked the pressure form the squeegee is checked If the pressure from the squeegee is to great the screen will be damaged and unusable Once this is set to the screens specifications the printing process may begin START Squeegee is buttered with a thin coating of paste Paste is also deposited in a pile before the image of the circuit DURING STROKE Squeegee travels in a single direction across the screen forcing the paste through the screen onto the ceramic tile or substrate The screen is also being pushed against the substrate to create a peeling
