Best Methods for Cutting PCBs
Tile Cutter vs. Guillotines
When it comes to cutting PCBs, there are various methods available, each with its pros and cons. Currently, many individuals opt for using a tile cutter due to its precision and ease of use. However, there are some drawbacks to consider.
- Tile Cutter: The tile cutter provides precise widths but may cause munching of copper and plastic film, leading to dust and noise issues. Using a wet blade with a tray of water can help reduce these problems.
- Guillotines: Guillotines, such as heavy-duty paper cutters and metal shears, offer a cleaner cut without cracking or damaging the protective film. The blade design ensures a consistent cutting angle, and metal shears have strong blades for efficient cutting.
Questions to Consider
For those considering guillotines for PCB cutting:
- How is the PCB prevented from flipping during the cut when the blade pushes down?
- When using metal shears, how can you keep the PCB steady for a straight cut?
- Does the blade stretching the cut-out part of the PCB render it unusable, especially when cutting large PCBs into equal pieces?
- Are heavy-duty paper guillotines with horizontal blades capable of cutting through 1.0 or 1.5mm PCB boards without cracking?
Exploring these questions can help you choose the best method for cutting your PCBs effectively. Thank you for reading!
