Tutorial on Partially Flipped Panelization

- Partially Flipped Panelization Method
In the layout engineering phase of PCB design, panelization is frequently employed. Panelization, in essence, involves assembling individual boards into a larger one, leaving room for V-Cuts, process edges, fiducials, tooling holes, and other process clearances.
During PCB prototyping, it is often more efficient to assemble small boards into a larger one in Altium before fabrication and assembly.
Partially Flipped Panelization Method
Today, let's delve into the partially flipped panelization method, specifically for PCB prototyping. Essentially, it involves transforming the TOP layer of the drawn PCB into the BOTTOM layer and vice versa for panelization.
Here are the overall steps:
1. Create a new PCB file and copy the completed PCB design into the newly created PCB file.
2. Perform a special paste.
3. Copy the entire PCB board, select it, flip it, and then rotate it 180 degrees clockwise.
To execute these steps:
1. Select the entire file (Shortcut: S+A).
2. After copying the file, perform a "special paste." Ensure you select the two middle options, as shown in the following image. After selecting these options, refrain from reapplying copper fill.
3. After copying the file, it should be positioned appropriately. At this point, select the move command and drag it. During the drag, a dialog box will appear. Please choose "YES." After dragging, the file can be moved with your mouse. Press the "M" key on the keyboard. When the dialog box appears, select "Flip Selection." As shown in the right image below, the file will be flipped, and you may need to adjust its orientation. Select the file again and use the "Move Command" while pressing the spacebar to rotate it 180 degrees and place it in the desired position.
When handing the design to the PCB manufacturer for PCB prototyping, it's essential to add the process edges. Select the "keep-out" layer for drawing. Add "tooling holes" and "fiducial points" on the process edges. Finally, use any layer, such as the "Overlay" layer or the "keep-out" layer, to label the V-cuts. With this, the entire panelization process is complete, as shown in the image below.

How to Determine the Right PCB Voltage Clearance for Safe and Reliable Designs
Key Takeaways Clearance is the air gap; Creepage is the surface path — both essential for high-voltage safety. Base spacing on peak voltage and follow IPC-2221 / IEC 60664-1 standards. Major factors: voltage, pollution degree, CTI, altitude, and conductor location. Use isolation slots, guard rings, and conformal coating to optimize spacing. Always run clearance calculations, DFM checks, and Hipot testing before production. Why do two copper traces that work fine at 5V suddenly arc over and burn at 400......
Mastering PCB Footprints: Design Best Practices for Reliable Manufacturing
Key Takeaways A PCB footprint (land pattern) translates component datasheet dimensions into copper pads, solder mask openings, paste apertures, silkscreen, and clearance areas that enable reliable soldering and assembly. Follow IPC-7351 standards and manufacturer DFM rules for pad dimensions, spacing, and layer design to minimize defects like solder bridging, tombstoning, and cracked joints. Choose between through-hole (THT) and surface mount (SMT) footprints based on electrical needs, thermal perform......
How Copper Thieving Balances Your PCB for Better Manufacturing Results
Key Takeaways Copper thieving adds non-functional copper patterns (dots, squares, or crosshatch) to balance copper density across PCB layers. This effectively reduces uneven plating (from 20-30% to <10%), board warpage, inconsistent etching, and impedance issues, delivering tighter tolerances, better solder mask adhesion, higher yields, and lower costs. For best results, target 40-60% copper density per layer, maintain proper clearances, and ensure stackup symmetry. When done right, it transforms comp......
ZIF Connectors Simplify Flexible PCB Assembly with Tool-Free Reliability
Did you ever attempt to mate a fragile flex cable into a connector and experience that unpleasant resistance, and wonder whether you were tearing off the tail or breaking the casing? It is precisely that tension that the ZIF connectors were supposed to help remove. Zero insertion force technology allows you to slide a flexible printed circuit or flat flexible cable into the receptacle to be mated with, using almost no push force at all, but rather allows a mechanical actuator to hold the cable firmly ......
PCB Terminal Blocks : A Design Engineer’s Guide to Reliable Wire-to-Board Connections
PCB terminal blocks are the unsung heroes of wire-to-board connections. They can be used to connect or replace wires in industrial controls, power supply, and automotive systems, etc, without needing to re-work the PCB. Terminal blocks can be tight-clamped or screwed, eliminating the guesswork of hand-soldering. However, terminal blocks may be problematic. Loose wiring can vibrate, heavy elements can be subject to solder-joint fatigue, and a lack of creepage or clearance can allow arcs to arc between ......
