The definition of Centroid
Centroid is a kind of special file.
This file can use for PCBA quickly programming through the SMT machine.
So, simply say Centroid is the file format of the PCBA.
Centroid, also known as aka Insertion, Pick-N-Place, or XY Data.
How to generate the Centroid of PCBA?
This is a really simple question about PCBA, but also have many new guys don’t know.
So 4MCPCB experts have summarized the generate method of Centroid of PCBA.
Some of the CAD software will automatically generate this type file.
And others were not automatically Centroid file, due to software setting.
4MCPCB experts told Frank that only modifies the file and then can output Centroid file.
4MCPCB experts explain Centroid file
As a PCBA design file, Centroid file is very important for PCBA.
The Centroid file have included three parts, position data, rotation and side of the board.
First, the position data of Centroid file.
It’s described the position and orientation of all the surface mount parts, also include the reference designator, X and Y position, and so on.
Then is rotation data of Centroid.
Last but not the least, it’s side of the board.
In other words, all PCBA components are listed in the Centroid.
