The origin set during PCB packaging is mainly for the convenience of design and production. Its main functions are as follows:

First of all, when making a package, it is generally necessary to take a position as a reference position to place the pad. In this case, the origin can be used as a reference position.

Secondly, in PCB design, the origin can be regarded as a reference position, and the origin can be grasped for device placement. If the origin position is set during packaging, it is beneficial to PCB design. If the origin position is not paid attention to when packaging, For example, setting the origin position far away from the pad is very inconvenient when doing PCB design to grab the device.

Finally, after the PCB design is completed, a GERBER file can be issued for PCB production and placement. Generally, a device origin coordinate file will be produced when the GERBER is produced. This file is used for placement, and it is responsible for placement during placement. The engineer of ”first needs to edit a program to grab the device according to the coordinate file of the device, and the placement machine grabs the device according to this program for placement. Especially for patch devices with a regular appearance, it is generally necessary to set the origin position at the center of the device, because the patch machine recognizes the center of the device.
