RFH UV nanosecond laser cutting FPC flexible circuit board has become the mainstream

High-precision cutting of FPC circuit boards is inseparable from RFH 355nm UV laser technology

 

FPC cutting

FPC flexible circuit boards are also what we often call FPC flexible boards. In terms of product structure, they are made of flexible copper foil substrates and flexible insulating layers, which are laminated by adhesives. It has many advantages that rigid circuit boards do not have. The use of FPC soft board can greatly reduce the volume of electronic products, and make electronic products develop in the direction of high density, high reliability and miniaturization. In particular, the upgrading of current electronic products will promote a jump in FPC production capacity.

 

FPC soft board is an important part of smart electronic products, such as display modules, fingerprint modules, camera modules, antennas, oscillators, etc. need FPC soft boards. According to industry research, the amount of FPC soft boards on the iPhone has reached more than 20 pieces. However, the cutting of complex FPC circuit boards is inseparable from UV laser technology.

 

Ultraviolet nanosecond lasers have a short wavelength of 355nm, small thermal impact, and cold processing characteristics. They have become the mainstream method of FPC cutting at present, and it is also a future trend.

 

The 355nm ultraviolet laser has high repetition rate, high precision and flexible operation, making it an irreplaceable position in the field of FPC soft board processing of intelligent electronic products.

 

In addition, compared with mechanical stress processing, UV laser cutting, non-contact processing, no tool loss, fast and efficient completion of FPC cutting, drilling and other complex process requirements. In mass production, manufacturing costs can be greatly reduced.

 

Cutting FPC circuit boards requires RFH Expert III 355 series ultraviolet diode pumped pulsed solid-state lasers. Others use unique laser cavity design, acousto-optic Q-switching technology, and high-precision cooling system, small size and high integration. And short pulse width (<20ns@40k), superior beam quality (M²<1.2) and perfect spot characteristics (spot ellipticity>90%) can meet the high standard cutting requirements of FPC.

Why RFH UV laser is often used in laser marking plastic button switch
Why RFH UV laser is often used in laser marking plastic button switch? More and more manufacturers choose UV laser marking machine to create pattern and characters on the plastic button switch. The focal spot of UV laser is pretty small with little heat transfer to surrounding material, so UV laser is also called “cold light source”. Because of this feature, heat effect won’t occur. Thus, distorting or burning of materials is no longer an issue.    Professional UV laser manufacturer - Shenzhen RFH Laser Technology Co.,Ltd    With 13 years of experience, the S9 series nanosecond UV laser developed and produced by RFH can engrave clear characters on the keyboard and the mouse. These kinds of characters can not only help people identify different buttons in the dark but also last long, for there are slightly protruding part on the buttons. This improves the durability and practicability of the keyboard and the mouse.
