Laser cutting and scribing flexible board FPC with RFH 15w UV laser soucre
The flexible circuit board is a technology developed from space rocket technology in the 1970s, but now it has more and more uses. In recent years, with the rapid development of the 3C industry, flexible circuit boards have broader application scenarios, but the cost of flexible circuit boards is relatively high, and quality control and loss reduction are common requirements for all relevant manufacturers.
RFH is well aware that the future development of single-sided and double-sided FPC flexible and rigid boards will inevitably control costs more and more precisely, and the way to manage this product is to mark the circuit board.
Mr. Zeng from Hunan came to RFH on behalf of his factory to purchase nanosecond 15w UV laser source for marking the flexible circuit boards he produced. Mr. Zeng said that in the past, traditional methods were mostly used for marking flexible circuit boards, such as pasting product barcodes, ink touch codes, printing, etc., mainly marking circuit boards with two-dimensional codes such as codes, barcodes, characters, and patterns.
However, the space occupied by the QR code is relatively large, and affected by subsequent processes, such as high temperature and high humidity, the information of the QR code will be blurred and incomplete, which will greatly increase the management cost. The nanosecond ultraviolet laser developed and produced by RFH just meets the management requirements of non-contact processing, no consumables, no pollution, and high precision, making it the current and future mainstream marking technology.
For FPC cutting, coding and scribing of flexible circuit boards, Expert III 355 series high-power ultraviolet diode-pumped pulsed solid-state lasers are recommended, which adopt unique laser cavity design, acousto-optic Q-switching technology, and high-precision cooling system. Small and highly integrated. It has short pulse width (<20ns@40k), superior beam quality (M²<1.2) and perfect spot characteristics (spot ellipticity>90%).
