PHOTOPLOTTER Meaning and
Definition
-
A photoplotter is a specialized device used in the field of electronics manufacturing and printed circuit board (PCB) design. It is primarily used to create precise and accurate prints of circuit board designs on various materials, such as films, photoresist-coated copper-clad boards, or photomasks.
The photoplotter operates by converting electronic PCB design data into physical prints through a process called photoplotting. It utilizes high-resolution optics and laser technology to expose light-sensitive materials, accurately reproducing the intricate circuitry layout. The design data, typically in Gerber or Excellon file formats, is taken by the photoplotter and converted into a series of precise and controlled movements of the laser beam, resulting in a detailed and mirrored image of the circuit board design.
The photoplotter's key advantages lie in its ability to produce high-resolution prints with minimal distortion, allowing for precise registration and alignment during subsequent manufacturing processes. It enables efficient prototyping and production of PCBs without the need for physical contact or printing plates. Additionally, photoplotting can handle complex multilayered designs, with each layer being individually plotted and aligned.
Photoplotters are widely used in the electronics industry, particularly in PCB manufacturing facilities and design bureaus. They play a crucial role in the production of high-quality, accurate, and reliable circuit boards, enabling the efficient creation of prototypes and the mass production of electronic devices.
Etymology of PHOTOPLOTTER
The word "photoplotter" is a combination of two elements: "photo" and "plotter".
The term "photo" is derived from the Greek word "phōs" (φῶς), which means "light". It is commonly used as a prefix in words related to light and photography, such as photograph, photosynthesis, or photovoltaic.
The term "plotter" refers to a device used for plotting or drawing images or graphs. It originates from the verb "plot", which means to mark down points or draw a course on a map or graph. In the context of electronics and printing technology, a plotter is a device used to produce high-resolution graphics or images by controlling the motion of a pen or other drawing instrument.
