Open PIK File
The PIK file extension is primarily used to save schematics related to PCB boards.
There are various software packages associated with this extension and format, however, the first application to use this format was the discontinued Protel 99 from Altium Ltd.
Protel 99 software has been replaced by Altium Designer which offers a unified environment that gives engineers a unified view of all aspects of the PCB design process, including schematic, PCB layout, harness design, and documentation. .
The software allows for the integration of all tools in one place, which in turn allows you to complete your design within the same intuitive environment and quickly deliver high-quality products.
The PIK extension file saves a design in XML format for later use in Altium Designer software.
