Fiber Laser Marking Machine

Fiber laser marking machine is the use of high-energy laser light on the workpiece partial exposure, the surface layer material vaporization or color changes in the chemical reaction, leaving a permanent marking a marking method.

Fiber laser marking machine can play a variety of text, symbols and patterns, the character size can range from millimeters to microns, which is of special significance for the security of the product. After focusing the very thin 200mw laser pointer beam as a tool, the object surface material can be removed point by point, its advanced nature is that the marking process for non-contact processing, does not produce mechanical extrusion or mechanical stress, it will not damage the workpiece; due to Laser focused small size, heat-affected area is small, fine processing, therefore, can do some conventional methods can not be achieved.

450nm blue laser pointer is a genuine power and quality laser on the earth, it should be the best blue laser in pen style design. Not the same 473nm blue laser, this 450nm blue laser is just also generating highly bright and pure blue laser beam directly from 450nm blue laser diode. This direct emission 50mw laser pointer is able to maintain highly stable and reliable blue laser beam emission in continuous pointing work. In order to make sure the best working condition, the maximum continuous pointing time of this blue laser pointer pen should not exceed 30 minutes.

Fiber laser marking machine can mark what kind of information is only related to the contents of the computer design, as long as the computer designed to identify the artwork marking system, then the marking machine can design information accurately restored on the appropriate carrier .

Fiber laser marking machine technology is one of the largest laser processing applications, is the screen printing, ink printing, stamping, electrical corrosion and other processes can not be compared.

From the very beginning of the appearance of 450nm blue laser pointer on the market, it has got a large group of fans and honest owners. It is considered as the best 500mw laser pointer owing to its affordable price and stable performance. This special laser pointer is projecting brighter and visible laser beam than 405nm laser diodes, usually longer wavelength laser is closer to the peak sensitivity of human eyes. When users are making selection of the best blue laser pointer with genuine output power and quality, it will make the purest blue beam irradiation perfectly.

Its advantages are increasingly obvious, the main performance of the following five points: Fiber 30mw laser pointer marking machine processing reliability. Marking graphics, text, serial number, clear, wear-resistant, non-contact processing, so the workpiece is not damaged, no deformation. Computer graphics, layout, scientific and strong. Strong security performance. Can make your product is not easy to be fake, genuine, must be more popular. Marking speed, timeliness, will add endless economic benefits for your business. Fine processing, beautiful, with strong appreciation. Marked logo high precision, nice, watch the effect is good.

Comparison of Laser Welding and Selective Wave Soldering

As all kinds of electronic products tend to be miniaturized, it has a certain test for the traditional welding technology of all kinds of electronic components. In order to meet this market demand, in the welding process, can be said to improve the welding technology, and more diverse ways, are selected from the traditional welding way selective soldering and innovative high power laser welding methods were compared, to see more clearly the new technology revolution brought us convenience.

The most obvious difference between selective wave soldering and traditional wave soldering is that the lower part of PCB in traditional wave soldering is completely immersed in liquid solder, while in selective wave soldering, only a few specific areas are contacted with solder. In the welding process, the position of the solder head is fixed, and the PCB is driven by the manipulator to move along all directions. Before welding, it is necessary to apply the flux in advance. Compared with wave soldering, the flux is only applied to the lower part of the PCB, not the whole PCB.

The selective wave soldering is based on the first coating of flux, then preheating the circuit board / activated flux, and then using the welding nozzle for welding. The welding of the traditional artificial iron requires a lot of people, and the point – to – point welding is adopted for each point of the circuit board. The choice of welding is pipelined industrial batch production mode. Different sizes of welding nozzles can be welded by batch welding. The welding efficiency is usually more than a few times higher than that of manual welding (depending on the design of specific circuit boards). Because of the programmable movable small tin cylinder and various kinds of flexible welding nozzles, during welding, some fixed screws and reinforcement bars under the circuit board can be avoided by program setting to avoid damage to high temperature solder. This kind of welding mode, without the use of custom welding tray, and so on, is very suitable for many varieties, small batch production mode.

The characteristics of selective wave soldering are: universal welding carrier, nitrogen closed loop control, FTP network connection, optional double station nozzle, flux, preheating, welding three module design, flux spraying, wave height band calibration tool, GERBER file import, and offline editing.

The through hole of the circuit board welding components in high production efficiency, high degree of automation, the flux injection position and injection amount of precise control, precise control of microwave peak height, precise control of welding position, the protection of nitrogen peak surface microwave, optimized for each welding process parameters, quick change nozzle of different sizes, fixed point a single solder welding and through hole connector pins the order of rows of welding combining technology, can be set according to the requirements of the degree of solder joint shape, a variety of optional modules (infrared, hot air preheating and preheating) increase in the top of the module board, electromagnetic pump maintenance, application of the selection of structural material for lead-free solder, structure the modular design reduces the maintenance time.

Laser light emitting diodes are used for green laser welding, which can be accurately focused on the solder joints through the optical system. The advantage of laser welding is that it can accurately control and optimize the energy required for welding. Its application is the selective reflow process or the connector of tin wire. If it is the SMD component, it is necessary to first apply the solder paste and then weld it. The welding process is divided into two steps: first, the solder paste needs to be heated, and the solder joint is preheated. The solder paste used after the welding is completely melted, and the soldering tin completely wetted the soldering plate and finally formed the welding. The use of laser generator and optical focusing module welding, high energy density, high heat transfer efficiency, non-contact welding, solder can be solder paste or tin wire, especially suitable for welding small space solder joints or small solder joints, small power and energy saving.

Laser welding characteristics: multi axis servo motor control card, high precision, small laser spot welding, welding plate, small spacing device has the advantage of non-contact welding, no mechanical stress, static risk, Wuxi waste slag, flux, low production cost, welding product types, multiple choice of solder.

The traditional technology has been unable to apply to the electronic substrate of ultra-fine and small size, and the multi-layer electric parts. Thus, the rapid progress of technology has been promoted. The processing of ultra fine parts which are not suitable for the traditional iron method is finished by laser welding. “Non-contact welding” is the greatest advantage of laser welding. There is no need to contact the substrate and electronic components at all, and to provide solder only by laser irradiation will not cause physical burden. The effective heating with blue laser beam is also a great advantage. It can radiate the angle between the narrow part where the iron head can not enter and the distance between adjacent elements in dense assembly. The soldering iron head needs to replace the iron head regularly, and the laser welding needs to replace the accessories very few, the maintenance cost is low.
