Online PCB Panelization Tool
Enter your board size – or upload your Gerber files – and how many boards you want per panel, then choose V-cut or milling with stamp holes, rails, fiducials and tooling holes. The panel is laid out with the same rules our engineers use for production and drawn instantly.
How the panel is laid out
V-cut
Rectangular boards are placed edge to edge and scored top and bottom along straight lines, so no material is lost between boards. The V-cut also runs between the boards and the rails.
Milling + stamp holes
Each board is milled free with a 2 mm router gap (also between board and rail) and held by 5 mm tabs with rows of 0.5 mm stamp holes, one tab about every 70 mm of edge.
Rails & marks
Rails carry the panel through the assembly line. Fiducials are placed 11 mm from the corners and tooling holes 5 mm from the corners; a hole too close to a V-cut is moved along the rail.
Frequently asked questions
What is PCB panelization?
Panelization places several copies of a PCB in one larger panel, with rails, fiducials and tooling holes, so the boards can be fabricated and assembled together and separated afterwards.
V-cut or tab routing with stamp holes?
V-cut scores straight lines between rectangular boards and leaves no gap, which saves material. Tab routing mills around each board and keeps it in place with small tabs perforated by stamp holes (mouse bites); use it for non-rectangular boards or components that overhang the edge. Mixed panels use V-cut in one direction and milling in the other.
Why add rails, fiducials and tooling holes?
Rails give the assembly line conveyor something to hold. Fiducials are copper marks the pick-and-place camera uses for alignment, and tooling holes locate the panel on fixtures. 5 mm rails are a common minimum; narrower rails leave no room for the marks.
What is the maximum panel size?
Our usual production limit is about 500 × 600 mm. Larger panels are possible on request.
Can I panelize my Gerber files here?
Yes. Click “Use my Gerber files”: the board size is read from your outline, the real board is drawn in every position, and tabs with stamp holes are placed on board edges without copper, pads or holes. Uploaded files are deleted after 24 hours. When you order, upload the same files for an instant quote and choose “Panel”. Check your design first in our Gerber 3D viewer and pick a stack-up.
