3W UV laser equipment used for FPC soft circuit and PCB board marking respectively

Lead: PCB is the abbreviation of Printed Circuit Board. The Chinese name is printed circuit board or printed circuit board. It is an important support for electronic components and a connection carrier for various electronic components, so it is also called a circuit board. A representative product is a computer motherboard.

UV laser marking FPC is a flexible circuit board

FPC is a flexible circuit board, or Flexible Printed Circuit for short. Because it has excellent flexibility and is relatively soft, it is also a circuit board that connects various components. It is usually called FPC flexible circuit board. Typical products are notebook computers, motherboards and The connection part between the displays uses FPC flexible circuit board.

UV laser marking PCB circuit board

Whether it is PCB circuit board or FPC soft circuit, it needs to be marked on it, the purpose is to better distinguish each circuit, know the role of each circuit, which electronic components and electronic equipment should be linked, and facilitate assembly and maintenance, etc. Staff distinguish. What equipment product is needed to mark the connection of these two electronic products?

In the laser marking equipment, the purple light belongs to the cold laser. It is the most suitable for marking on the FPC soft circuit.

First of all, let’s look at the FPC flexible circuit board made of polyimide or polyester film as the base material. The melting points of these two materials are relatively low. In this case, if red light is used, the FPC flexible circuit board may be burnt. The coke even melts and cannot be used. In the laser marking equipment, the purple light belongs to the cold laser, which is the most suitable for marking on the FPC soft circuit.

It is best to use a purple laser marking machine for PCB marking

The PCB board mentioned above is a printed circuit board. The laser equipment marking is good at marking off the surface layer. The power and frequency marking speed of the laser marking machine can be adjusted according to the thickness of the printed circuit board. It is the most suitable power that does not damage the printed circuit board. It is recommended to adjust this power after multiple samples or professional tests to avoid unnecessary trouble caused by damage to the product during the marking process. This kind of marking is theoretically possible with four types of laser equipment. In fact, it is best to use a purple laser marking machine for marking. Using a fiber laser marking machine for marking is the most cost-effective, and using a laser inkjet printer for marking is faster.

From the above summary, we can see that the PCB printed circuit board is not so particular about the marking of laser equipment. Not many devices can be marked on it. As long as the power is adjusted to the appropriate power, the product itself will not be hurt. Due to the special material requirements of FPC soft circuit, the laser marking machine has strict requirements for marking. In theory, the purple laser marking machine is the most suitable.
