Optionetics Review: Why Do Some Call It An Optionetics Scam?
Optionetics is a seminar and software options training program created by George Fontanills. Optionetics offers free nationwide seminars which they use to promote their paid courses and trading software.The free Optionetics events are headed by high pressure reps that concentrate on one cause. They present handfuls of useful trading methods but spend the majority of the time pitching additional Optionetics scam products. They also have a tendency to lecture at a quick and overwhelming pace in order to make people feel like they need the extra services offered by Optionetics.The Optionetics paid seminar will run you close to 3k for 2 days of training and supplements on options trading. I’ve spoken to many folks that attended these seminars and have received varied feedback on the training. Everyone agrees that the usefulness of the course is closely associated with your initial level of options knowledge. However, the Optionetics staff claim that your preliminary trading skills are irrelevant since they can train anyone that’s willing to learn.Overall folks who were not well ver

Year End Tax Savings for Cash Basis Taxpayers
There are only a few days left in the year. So now is the time to take those last minute tax savings.Disclaimer: I am not a lawyer, nor do I play one on TV. So do your due diligence and either check with your CPA, tax planner, or the IRS site.If you are a cash-basis taxpayer, as many sole proprietors are, you claim expenses as they are paid. Likewise, you claim revenue as you deposit it.So take a quick look at your annual Profit and Loss statement and decide: Do you need more revenue or more expenses?Now I'm not talking about making more money. I'm referring to when to claim the money.If you are facing relatively low income for this year, as compared to what you think you will have next year, then you may want to move as much revenue into this tax year as possible. So gather up all those checks lying around and head for the bank. Send out invoices via paypal to vendors who may be willing to pay you this year. Call people who may already have an invoice they could pay. Pull as much revenue into this year as possible.On the other hand, if you've made more mone

The electronics Printed Circuit Board industry is evolving as new production technologies become available at low cost. Direct digital printing is making inroads into the traditional photolithography and screen printing processes that have been used to manufacture PCB for the last twenty years.

Here we will focus on the use of direct digital printing to individualize PCBs just prior to their assembly. The goal is to print a unique mark on each board that can be used to identify the board. The mark must be permanent and will probably contain 1D or 2D machine readable codes along with alpha numeric characters. The marks must have a 600 DPI (dots per inch) resolution or better due to size constraints on the PCB. We will also focus on applications that require more that 1,000,000 boards per year. At these volumes automated material handling starts to become very important to the overall success of the system.

High volume PCB fabricators use screen printing with thermally cured ink to print the legends that cover each side of the board. At this time digital printing can not print the whole side of a board at a price that competes with screen printing. Even though many printers, including the PPS7000, could print all the nomenclature on the board, here we will focus on using digital printing only to print the individualizing marks.

Several individualizing options exist including the following:

Preprinted Label Application

Many low volume products start with labels printed on office equipment and hand applied to each PCB prior to or after assembly. As the product volumes ramp the reliability and cost of hand applying labels becomes a problem. Automated systems that print and apply labels are available. (see this site ) Because of PCB space constraints these systems must place labels very accurately, a big problem for many label application systems. The labels are not permanent. At high volumes the labels are more expensive than other marking methods.

Advantages

Low Initial Cost

High Contrast Mark

Disadvantages

Not Permanent

Higher Incremental Cost

Difficult to Change Label Size On The Fly

Mechanical Complexity For Automated Application

Solvent Based Continuous Ink Jet Digital Printing

Continuous ink-jet technology has been adapted to mark on many industrial products including PCBs. With these systems a continuous stream of ink droplets is steered to the desired location using electromagnetic fields. Solvent based inks produce permanent marks on porous surfaces. The marks are less permanent on non-porous surfaces where smearing may be a problem for the short time its takes to dry.

Advantages

Many Colors Available

Disadvantages

Complex Ink Viscosity Process Can Be Difficult To Control

High Resolution (Greater Than 300 DPI) Difficult To Achieve?

Solvents May Be Released Into Atmosphere, Many Companies Trying To Reduce Solvent Issues

Mark Not Resistant To Some Cleaning Solvents

Laser Ablated Ink Patches

Many industries use lasers to engrave marks onto a variety of parts. Lasers have been used to engrave marks onto PC boards with limited success due to the lack of contrast of the resulting mark. A newer approach is to have the circuit boards printed with ink patches, the ink patch is then selectively removed (ablated) by the laser creating the mark to be printed. (see here ) PPSI has the capabilities to develop a laser based marking system.

Piezoelectric Drop On Demand Digital Printing, Thermally Cured Ink

A startup company in Israel “Printar” has introduced a printer targeted at low volume, fast turn PCB fabricators who need to reduce the cost and lead time associated with small lot screen printing. Interesting is their thermally cured ink that reportedly has better adhesion capability than other ink systems.

Advantages

Piezoelectric Drop On Demand Digital Printing, UV Cured Ink

Markem Corporation has developed an ink/print head system ( the Model 4000, see here ) that several OEMs and integrators are using to print on PCBs. The system uses an ink that is less viscous at high temperature and almost solid at room temperature. The print head operates at 68 deg C, the ink drops cool when they contact the PCB becoming almost solid. This allows the system to print fine detail on PCBs without ink running or smearing. When exposed to UV light the ink undergoes a chemical reaction becoming a solid plastic like substance. The cured ink is impervious to common solvents.

Getting Your Electrician License
One thing you need to know about getting certified and receiving your electrician license is that it’s going to take a lot of hard work on your part. There is quite simply a lot to learn before you could even begin to think about taking the state testing required to receive an electrician license. Whether you take an online course, attend schools, or study by yourself at home, there’s a lot to learn in order to pass the license test.Here’s an overview of one course that leads to successful licensing. It begins with learning strategies, what type of student you are, and how best to approach the material. It quickly moves into a simple explanation about electricity, house circuits, and electrical distribution. From there it moves on to discuss safety, national electrical codes, federal OSHA requirements, and what to do if you or someone else gets shocked on the job.After that electrical equipment and supplies are discussed – meters, circuit analyzer tools, conductors, insulators, conduits, resistors, switches, relays, thermostats, remote controls, and fuses.Once you’re familiar wi

Learning From Students
Yesterday evening I was invited to present end of year and exam certificates to students at a local school. I was absolutely thrilled to do this particularly as I have been involved in helping many of the business students over the last couple of years.The academic achievements were fantastic. And whilst most students matched my expectations, two students really surprised me.The first one came on stage to rapturous applause from his classmates. I was intrigued and asked him, “How come you’re so popular?”“Do you want to see my dance?”“Okay,” I said. Not knowing what to expect.He then launched into an incredible routine. I’d describe it as a form of break dancing but I don’t profess to be an expert on these things. It lasted about 10 seconds and received huge applause from all 300 parents and students in the audience.The second student to surprise me, did so in a very different way.This young lady was dressed in a long black leather coat and black leather boots. She wore a black hat with a black lace veil drawn over her face. Behind the veil, bl

Graphic Designs
Graphics are needed everywhere and are being created by millions of people all over the world. The real art is not just in creating graphics but arranging them in conjunction with other text and images to produce a coherent and interesting piece of work, according to the end goal. This is what is meant by graphic design. The process of graphic design enhances the look of a layout, is attractive to viewers, simplifies the message and helps communicate a message effectively. As simple it may seem, it is lot of hard work.While creating a graphic design, designers plan and analyze factors such as audience, aim of the message, and medium (such as print, online, book or poster). Once basic requirements are sorted out, text and graphics are organized on selected formats and layouts. Fonts, color, size and arrangement of text and graphics are re-looked at and sent for proofreading. While doing any graphic designing, basic elements design like line, shape, texture, space, size, value, color, balance and rhythm are used. Graphic designs also need to respect the principles of design like balance, color,

Home Buying Checklist - Paint and Stucco
Buying a home is a big investment. You should use a checklist when sizing up potential homes. In this article, we cover a home buying checklist for paint and stucco.Paint and StuccoThe exterior of a home typically makes the biggest impression when you first view a potential buying opportunity. Many homebuyers, however, often make the mistake of looking at color schemes as the principal issue. In truth, a close review of the exterior of the prospective home can tell you a lot about the quality of the structure.A person selling a home is not stupid. Before putting a home on the market, they are going to take steps to spiff it out to raise buyer interest and the rate you are willing to pay. There is nothing devious about such conduct. It is natural to want to put your best foot forward and a person selling a home isn’t going to act differently. This is why you want to take a close look at the exterior paint and stucco on a home.1. The first thing to look for is peeling or flaking of paint on the exterior walls. If you see this in an obvious place on a wall, run for the hill

The PPS 7000

The PPS7000 has been designed to print individualizing marks on PCBs using option 6. The system uses a SMEMA compatible edge belt conveyor to move PCBs to the print area where they are printed and optically inspected. After inspection they are conveyed to the inline curing station and then out the back of the machine. When being automatically loaded by a board destacker, panels exit the system about once every 10 seconds. Each panel usually contains multiple boards that each receives a unique serial number. The overall throughput of the machine is highly dependant on the number of boards in each panel. The more boards in each panel the higher the throughput in boards per minute. A drag and drop WYSIWYG (What You See Is What You Get) programming system has been developed that allows a new panel to be programmed in approximately 5 minutes. An offline programming system is also available.

We are the only PCB board marking system that creates a permanent (solvent resistant) high contrast mark, incorporates SMEMA compatible high volume material handling and incorporates inline inspection.

Next Steps

If the PPS7000 looks like it may meet your requirements the next step is to print samples for you in order to verify that the ink will adhere well to your substrates.

To become a financial planner, you first must know what their job profile is. Financial planners help in determining the financial resources required to meet the company’s operating program. They also help in forecasting the extent to which these requirements will be met by the internal generation of funds, and the extent to which they will be met from external sources. It’s the job of financial planners to develop the best plans to obtain the required external funds. They also help in establishing and maintaining a system of financial control governing the allocation and use of funds. Financial planners formulate programs to provide the most effective cost-volume-profit relationship. It’s the job of financial planners to analyze the financial results of operations, report the facts to the top management and make recommendations on future operations of the firm.
