Beam-steered Nd:YAG
The beam-steered Nd:YAG provides more marking power and far superior imaging than any other laser marker configuration. The available high peak power can mark or engrave a wide variety of materials including hardened metallics. Present computer technology produces highly intricate graphics with linewidths and accuracy's of less than 0.001 inch. Because “drawing” with the laser beam creates the image, the marking time is dependent on the amount of text and the complexity of any graphics. The Nd:YAG laser marker is the most costly of the three system configurations. The beam-steered Nd:YAG marker frequently replaces acid and electro-etch systems, stamping and punching systems, and those other marking systems which permanently mark products by imprinting or engraving. It also replaces ink jet and other color printing systems. Typical applications include marking pistons, bearings, valves, gears, and a multitude of other components in the automotive industry; heart pacemakers, replacement hip joints, and surgical tools in the medical industry; computer chassis, disk drives, and integrated circuits in the electronics industry; tool holders, drill bits, and cutting tools in the tool industry; and writing pens, nameplates, and golf club grips.

Most people dread job interviews. The very thought of one is enough to send them into a cold sweat. Most people see the job interview as an interrogation. In fact, job interviews are as much for your benefits as the company’s. The interview gives the company an opportunity to get to know you, and it gives you a chance to decide whether or not you want to work for them.Although it is only natural to be nervous you will find the whole process is not as scary as you might think. With a little bit of preparation you can be ready to answer anything that the interviewer throws at you.Naturally you can't prepare for every question that will come up at interview, but you can anticipate most of them.Let me guide you through the process and give you a few tips:First, try and relax during as soon as you can in the interview. A good interviewer will want you to feel at ease so that you can deliver well thought out answers without feeling panicky. They will start off with friendly, general questions about you to put you at ease.You will find that the tough interview questions are the ones that are open-ended. However, this is not all bad news.

Two marking system designs have emerged with notably different strengths and weaknesses. Careful consideration of these laser and imaging optics combinations can provide the optimum tool for a wide range of marking requirements. Process Fundamentals
Laser marking is a thermal process that employs a high-intensity beam of focused laser light to create a contrasting mark. The laser beam increases the surface temperature to induce either a color change in the material and/or displace material by vaporization to engrave the surface. Both marking system configurations utilize this principle of surface modification but differ in the method used to project the laser beam and create the marking image.
The beam-steered laser marker provides the greatest degree of image manipulation. To create the marking image, two beam-steering mirrors mounted on high-speed, computer-controlled galvanometers direct the laser beam across the target surface. Each galvanometer provides one axis of beam motion in the marking field. The beam projects through a multi-element, flat-field lens assembly after reflecting off the final steering mirror. The lens assembly focuses the laser light to achieve the highest power density possible on the work surface while maintaining the focused spot travel on a flat plane. The laser output is gated between marking strokes. This design offers the user the advantages of a computer generated marking image and utilization of the entire laser output for the highest marking power possible.
The mask or "stencil" marking system sacrifices image quality and versatility for significantly increased marking speed. The marking image is created by enlarging the laser beam, projecting it through a copper stencil of the desired image, and refocusing the beam on the target surface to "burn" the image into the material. A single pulse of the laser creates the entire image. If the alphanumeric characters must be altered part-to-part, (i.e., serialization, etc.), computer-controlled rotary stencil wheels index the characters. This technique is aesthetically limiting in that images exhibit a "stencil" appearance with breaks in the marking lines. Since the mask blocks a high percentage of the laser beam, marking power and resultant surface penetration is limited. Laser and Imaging Combinations
Beam-steered Nd:YAG
The combination of the Nd:YAG (Neodymium:Yttrium Aluminum Garnet) laser and the beam-steered delivery optics marks the widest range of materials and provides the versatility of computer controlled image generation.
Nd:YAG lasers amplify light in the near-infrared at 1.06 mm. Metallic materials absorb a comparatively high percentage of the light in this region of the spectrum. In the pulsed mode, the Nd:YAG laser produces peak powers considerably higher than the normal continuous-wave output. A 90 watt CW Nd:YAG laser, pulsed at 1 kHz, will emit a train of pulses with peak powers of 110,000 watts. The Nd:YAG lasers ability to emulate an "optical capacitor" provides the power necessary to vaporize metallics and other materials. The high peak power will vaporize material up to 0.005 inches deep in a single pass or greater with multiple passes. The non-metallic materials normally associated with the far-infrared wavelength of the CO2 laser are usually highly reflective to the Nd:YAG. However, the high peak power of the Nd:YAG can often overcome the higher reflectivity. Some overlap does occur among many plastics that absorb both wavelengths equally well.
The beam-steered marker can duplicate virtually any vector graphic image including variable line widths and images as small as 0.010 inch or less. In addition, the computer can instantly change any graphic element or the entire marking program before a new part is positioned for marking. The Nd:YAG laser offers a greater range of adjustable process variables to achieve a specific material modification but at a correspondingly higher purchase price than the CO2 laser.
Beam-steered CO2
The continuous-wave CO2 laser can also be combined with the beam-steered delivery system. CO2 lasers emit a narrow bandwidth of light in the far infrared at 10.6 mm. This wavelength is most suitable for organic materials such as paper and other wood products, many plastics, removing thin layers of ink or paint from a substrate, and for marking ceramics. It does not produce high peak powers when pulsed.
Typically utilizing laser powers up to 50 watts, these systems combine the far infrared wavelength with the image control and flexibility of beam-steered image generation. Typical uses include serialization of ceramic and plastic products that require high-quality graphics such as company logos and/or significant amounts of additional alphanumeric text. The lower power CO2 marker does not provide the power to "engrave" substrates but, due to the comparative simplicity of design, can be purchased at a lower cost than the beam-steered Nd:YAG marker.
Mask CO2
Applications that require high speed but not high power and do not vary the marking image except for alphanumeric text (i.e., serialization, date code, etc.) utilize the mask CO2 marker. The CO2 laser is pulsed at rates of up to 1,200 pulses per minute. The high repetition rate provides marking of parts "on-the-fly" at high part-transfer speeds. Computer controlled masks can alter up to three lines of text at speeds of up to 720 parts per minute if the alphanumeric code must be changed.

If the credit bureaus rate your credit high, you may find your mailbox flooded with credit card offers from the thousands of credit card issuers in the country. There are many banks offering various credit cards, with rewards this and rewards that; platinum, gold, or silver; and so many variations thereof. You may get offers from your professional organization (lawyers, doctors, and engineers), your alumni association, and your environment club or sports association. Thousands of others, who are rated as safe payers by the various credit bureaus, receive similar offers. In fact, every year credit card issuers send out several hundred millions of offers.To process all of the applications resulting from these offers, the credit card industry makes extensive use of quantification, or credit scoring, to double check whether an applicant should be issued a credit card (or even become target for other kinds of credit). The industry turns to credit bureaus for the quantification part.The credit bureaus credit scoring systems give creditors the capability to evaluate millions of applicants on a consistent and impartial basis.

Don’t get me wrong. I think LLCs, or limited liability companies, are great. At modest cost, they often let you minimize your legal liability. LLCs also give you tremendous tax flexibility, because with an LLC you can choose to be treated as a corporation, an S corporation, a partnership (if there are multiple owners), or a sole proprietorship (if you’re the only owner).In spite of these big benefits, four good reasons exist for not forming a limited liability company for your next business. Here they are:State Income & Franchise TaxesAll states charge at least a modest fee—sometimes less than $100—to set up an LLC. And that’s not so bad, but here’s what is bad. Some states like California also levy additional unfair annual fees and franchise taxes on even the smallest LLCs.California’s minimum annual LLC franchise tax, for example, is a whopping $800. Ouch.If you’re operating in states with high annual LLC fees and taxes, you need to think twice about using an LLC unless your business is big enough to easily shoulder any extra fees and taxes.Complicated Bookkeeping and AccountingFor sole proprietors, an LLC may complicat

There are tons of digital projectors available and they are constantly dropping in price. However, when choosing a projector for yourself or your school there are a few practical things you should remember.When choosing a projector you need to consider under what circumstances will you be presenting slide shows. The strength of a projector's brightness is measured in units called lumens. Projectors range between 650-5000 lumens. The higher the lumens the brighter the projector. Projectors that are less than 1000 lumens may not be great in a room with a lot of ambient light. For a classroom you should consider buying a projector with greater than 1000 lumens. If the projector will be used for larger presentations, for 100 or more people, a projector with greater than 3000 lumens may be needed.A great accessory to your projector is a wireless mouse. These have dropped considerably in price and allow the educator to face their audience when presenting the slide show. When choosing a wireless mouse choose one that has a long range so that you can walk around when presenting.Many projectors also come with remotes that help the presenter ma

We all love to be welcomed warmly, attentively waited on with polite and enthusiastic anticipation of and fulfillment of our needs by a professional looking worker with a subservient attitude. This is customer service.Customer Service can be a great attractor for a customer to return to buy that product or service again, but it is not the only factor. What if you are in a restaurant and the service is great, but the food is bad? What if the environment is not clean or attractive? What if you can’t find a place to park or have to wait in line?These and a host of other satisfaction factors will ultimately influence your decision to return to that establishment or recommend it to others. The combination of all these factors in the mind of the customer is what is meant by customer satisfaction.In his recent book, “What Customers Want!”, Bart Allen Berry presents the results of years of customer satisfaction research, and reveals the ten domains of satisfaction customers are influenced by in any product or service delivery. Berry’s research finds that customers change their selection, return and recommend behavior based upon their overall satisfaction experience.ntages and Disadvantages

Beam-steered CO2
The acquisition and operating costs of the beam-steered CO2 marker are lower than the Nd:YAG marker due to the relative simplicity of the laser. Image generation is equal to that of the other beam-steered system while speed and depth of penetration are considerable lower due to the lower power of the CO2 laser. Although not as popular as the beam-steered Nd:YAG and mask CO2 markers, the beam-steered CO2 system is frequently used for marking general plastics and plastic and ceramic connectors and packages within the electronics industry.
Mask CO2
Although the mask CO2 does not offer the imaging capabilities of the beam-steered design, it is far superior in speed. Because a single pulse of the laser creates the entire image, throughput is typically limited only by the pulse rate of the laser and the transfer speed of the parts handling system. While the part must be stationary while marking with the beam-steered design, parts are marked in motion with mask systems. Depth of penetration is less than the beam-steered CO2 marker since the laser output is spread over a large area with correspondingly low power density.
Masked CO2 markers most frequently compete with ink-jet marking. The mask CO2 laser is often the marker of choice for sequenced coding, batch coding, open or closed date coding, and real-time coding of paper or cardboard, ink or paint coatings, glass, plastics, coated metals, and ceramics.
While the beam-steered design provides superior imaging and material penetration and the mask design provides superior speed, either system provides a better combination of speed, permanence, and imaging flexibility than other marking techniques. Many users also benefit from the non-contact nature of laser marking and the elimination of additive materials such as inks or paints.
The development of a successful marking application requires careful consideration of the laser output characteristics, the design of the optical beam delivery and image generation system, the properties of the target material, and the aesthetic and physical properties of the desired mark. Industrial laser marking systems provide prospective users with several system designs from which to choose to match the optimum marking performance with the users unique requirements.
