Problems solved by technology

Conversely, if figure 2 As shown on the left side of , when the distance from the inkjet head 104 to the substrate 108 is too far, the inkjet droplet 110 cannot land on the predetermined position
In addition, if the distance between the inkjet head 104 and the substrate 108 is too short, there may even be a risk of scratching the substrate 108 or causing damage to the inkjet head 104
[0011] It is known that adjusting the distance between the inkjet head and the substrate can only be manually fine-tuned by micrometers, but this cannot accurately control the thickness of the substrate after each replacement of the inkjet head (with the same specification or a different specification) When changing, the distance between the inkjet head and the substrate will cause the inkjet droplets to trail or fail to fall on the predetermined position
In addition, it is known that the use of manual fine-tuning will increase the time required for the process
