In the process of forming, on a substrate, a multi-layered circuit pattern with layers each having a portion made of the same material throughout the different layers in the direction in which the different layers are stacked, the position of nozzles with respect to the substrate when at least one of the layers is formed is shifted from that when the other layers are formed.
摘要:
A circuit pattern forming method is provided which can reduce a possibility of undesired short-circuits being produced in the circuit by satellites formed when fabricating a conductive pattern and thereby can form a highly reliable printed circuit board. To that end, this invention overlappingly draws a conductive pattern and an insulating pattern of a predetermined thickness by scanning a liquid ejection head and a substrate relative to each other a plurality of times while ejecting droplets of a conductive pattern forming solution and an insulating pattern forming solution. When forming the conductive pattern and the insulating pattern that adjoin each other on the substrate, the step of forming the insulating pattern of at least one scan is executed between the conductive pattern forming steps that are executed the plurality of times until the conductive pattern has a predetermined thickness.

The present invention is intended to provide a highly reliable circuit pattern forming device which can cause a conductive solution to land on the substrate with high precision and which, when forming a multilayer printed circuit board, prevents closely arranged wires from becoming short-circuited. To realize this objective, this invention forms a circuit pattern by ejecting onto the substrate the droplets of insulating solution and the droplets of conductive solution while moving the liquid ejection unit and the substrate relative to each other. During this process, when both of the droplets are landed close together on the substrate, the droplets of insulating solution are made to land on the substrate prior to the droplets of conductive solution.
摘要:
When forming circuit patterns by ejecting a minute amount of a conductive pattern solution and insulating pattern solution from a liquid ejection head in the form of an ink-jet head, a break or short circuit in a circuit caused by an ejection malfunction is prevented. During the forming process of the circuit patterns, preliminary ejection of the liquid ejection head for forming the circuit patterns is carried out toward an area without the circuit patterns. In addition, the preliminary ejection is carried out at intervals less than an ejection interruption time that might cause the ejection malfunction.
