KTI's PCB Board Splitting Machine is in a class of its own in the world!

A board splitting machine (depaneling machine) separates many individual boards from a panelised sheet at the same time, raising production efficiency. Machine types include router processing, dicing, stamping and press-cutting.

Printed circuit boards use glass, composite or paper base materials; depending on the machine, all base materials can be processed.

1. Router splitting: boards 0.4mm–2mm thick can be divided in vertical, horizontal and diagonal directions. Entering the cutting coordinates at the terminal makes board changeover easy, but router processing produces a lot of dust — know-how is required for jig design and the dust vacuum system. Fibre whiskers appearing on the cut face can be reduced by cutting twice. Component height on the board is limited and cutting speed is relatively slow.

2. Stamping: all dividing positions on a sheet are cut simultaneously in one shot, so separation is very fast, even with tall components. Little dust is produced, making it suitable for high-volume production. However, the cutting die is expensive to produce, and the stress applied to the board during splitting is high, which can affect board quality.

3. Press-cutting: suitable when production volume does not justify the larger initial investment of router or stamping machines. Not suitable for paper-based boards.

Panelised boards use either V-groove or perforation (mouse-bite) dividing patterns. KTI provides automatic splitting machines for perforated boards, V-cut grooved boards, and combined boards mixing perforation and V-cut splitting.
