It does not reopen
A frozen version is not corrected. What comes next is a new version linked to it.
How it works
From the empty project to the revision that gets manufactured
XKEMA does not ask you to migrate anything before you start. You open it with a real product, build its structure the way it actually exists, and hang the information where it belongs as you need it. This is what happens at each step, and also what does not.
Step 1
You create the project and go into the library
The central library is where everything reusable lives: stackups, PCBs, boards and equipment on one side, and the component families on the other —passives, discretes, integrated circuits, connectors, optoelectronics, electromechanics, materials and substances—.
You do not have to load it all before you start. You enter what shows up in the product you are building, and from then on it is available for the next ones.
Step 2
You build the product structure
Equipment contains boards; a board has its PCB; a PCB has its stackup. The structure is declared the way it really exists in the product, with the quantity of each child element.
That hierarchy is not decoration: it is what turns “the power supply” into something you can look up. The product configuration comes out of it.
Step 3
The bill of materials hangs from the board
The BOM is created inside the element it belongs to, not as a file named after the product. Each line points to a record in the library —manufacturer, part number, properties, datasheet— instead of to text that every person types their own way.
And the BOM has its own version. Changing it does not renumber the board, and changing the board does not renumber the BOM.
Step 4
You connect the documentation to the element it describes
Schematics in PDF, Gerbers, drill files, IBIS and SPICE models, footprints and symbols. Each document is tied to the element it actually describes, and opens in the browser without downloading it.
This is where XKEMA meets your design tool, and where it parts company with it: XKEMA does not draw schematics and does not route boards. It stores, relates and versions what comes out of the design.
Step 5
You freeze the revision that gets manufactured
Up to here everything is editable, which is how it has to be while you are designing. The last step is saying “this is the one”. The freeze is requested, whoever has to sign signs, and the version is closed with a fingerprint of its approved content.
It can be compared
Two versions are placed side by side: the BOM row by row, the PDF page by page and the Gerber by its geometry.
It can be verified
The fingerprint is recalculated whenever you want and compared with the one stored on the day of approval.
What XKEMA does not do
It does not replace your design tool: it does not draw schematics, does not route boards, and does not open the ECAD's native project. It does not raise purchase or manufacturing orders. It does not look up distributor prices or stock, so it will not warn you when a component goes obsolete either. And it does not track unit by unit with serial numbers.
