DIY PCB Fabrication Using Laser Printer

Electronic circuitry is indeed complex that hooking up all its components, including diodes, condensers, capacitors, transistors, resistors, and many others requires plenty of wires and room to contain all of them. As a result, printed circuit board or PCB fabrication had been formulated to simplify and facilitate the process of circuitry. PCBs are also responsible for the compact size of the electronic equipment at present. Do-it-yourself PCB fabrication is deemed as the standard procedure designed for enthusiasts in building variation in the design of the circuitry, though many favor laser printers because of the convenience they provide from preparation through completion.

What is in a Printed Circuit Board?

PCB fabricationA printed circuit board is generally made out of a hard insulated substrate, a thin layer of copper, and a surface clad. The printed circuitry is placed on the surface of the copper. The board is then drenched in an etching solution to eliminate copper in surfaces not included in the design. After that, holes are drilled through and several electronic components are set in position and soldered. Ammonium Persufate or Ferric Chloride is the etching solution that can be used for this step.

Why laser printers is good at making DIY PCB?

To build the circuit pattern, it should be engrossed in an anti-etch substance. Toner is a great example of an anti-etch substance since it will not melt or break down when drenched in the etching solution. It is generally made of carbon particles and plastic.

How is the toner transfer method performed?

At the moment, it is still not possible to print circuit layouts directly on the printed circuit board though experts are carrying on with the study to make it happen. While it is still not feasible, it is the toner transfer method that is most widely used. The process of doing this is detailed below.

1. The first step of the toner transfer method involves printing of the circuit layout on a special paper using a laser printer. The printed layout is then laid flat over the side of the board with the copper.

2. Apply heat on the printed media to make it possible for fusing. The goal in this step is to transfer the printed design directly on the board’s copper surface without the need to use any sort of chemicals.

3. After a few minutes of exposing the printed toner to heat, the laser printer toner is now able to stick to the surface it touches. The circuit layout that remains to be sticking to the surface of the copper will function as the anti-resist material.

4. For setups that are more complex, make use of a flat iron or modified laminating device for fusing.

5. As soon as the fusing process is completed, submerge the printed circuit board in water. By doing this, the cover paper can already be taken off. Examine the printed layout for any rupture.

6. The printed circuit board is then drenched in the etch solution in order to clear away the board of copper. When the board is already cleared, provide a protective covering by spraying transparent green enamel.

7. Finally, the PCB fabrication process is concluded by drilling holes on the board and then installing the different electronic parts.

Indeed, performing PCB fabrication at home is a fairly basic process.

What the makers would need is only patience, particularly in the initial steps of the process. Aside from the board where all the other electrical components are going to be installed, only a computer, a printing device, and an etching solution are the required tools to complete this application.

Guidelines in Buying Neck Lanyards for Companies and Organizations

Neck lanyards are not created equal. Aside from the material, imprinting method, and hardware used, there are also other factors that need to be considered before placing your order. Here is a quick guide to help you with the process.

Quantity of the Order

Neck LanyardsJust like any merchandise, lanyards cost lower if ordered in bulk. This is why you need to determine the quantity (be accurate as possible) before finding a supplier. Most suppliers can’t give you a quote if you don’t give them a quantity. It is recommended to order more than the current headcount in case the organization gains a new member or there will be cases of lost, missing, or broken lanyards. As much as possible you want to avoid placing very small order in the future to cater the mentioned scenarios because it will cost a lot more.

Budget

Determine how much the organization is willing to spend on neck lanyards. If you have a very low budget that all you can get are hot-stamped lanyards, which are only appropriate for short-term use, but the organization is looking to use these lanyards five times a week, propose a higher budget to the management accordingly. Highlight the pros and cons of the different types of lanyards. Initially, it might seem that you are spending more, but you can actually save a lot in the long run if you consider quality as your top priority. Just as long as they are within the average price range, do not try to haggle with suppliers as this can affect the quality of the finished products.

Design

You probably already have an organization logo or design that you want to use for your lanyards. However, if you still don’t have any, ask prospective suppliers if they can provide free graphic design services for you. Most of the times, especially if you are ordering in bulk, they offer this service for free.

Do not try to save on costs by designing the text or logo yourself, especially if you lack the skill and the experience. Remember neck lanyards play a role in promoting the organization and establishing its identity, so you must be sure that your design is professionally made. Also, make sure the design and color combination is approved by management before proceeding to the next step.

Samples

To have a good idea of the quality of lanyards the supplier is capable of producing, ask for samples. In fact, most suppliers, with the exemption of online retailers as they only provide pictures, give you a sample of their products. Be cautious when you are looking to get services from an online supplier. Be sure they are not bogus by reading reviews and see if they have a number you can call. Never ever get the service of a supplier that only transacts through non-voice methods.

Survey

There are tons of options to choose from when selecting neck lanyards. This can be overwhelming if decided only by one person as not everyone, or at least the majority, would be happy with his choice. To address this issue, create a survey among organization members. Most of them have worked in other companies or are members of different organizations that may have used different types of lanyards, so they can definitely help you decide which is the best option. The survey should include, but is not limited to, the length of the lanyards and the hardware used (e.g. split rings, quick-release, bulldog clips, J-hooks, size adjuster). Some may not be familiar of these things so briefly highlight their pros and cons. Other may know what they are but don’t know how they are called, so it’s also better to provide pictures on the survey.

Although you can also include which fabric should your neck lanyards be made of, this factor is highly dependent on your budget and printing method.

Remember Neck lanyards play a role in promoting the organization and establishing its identity, so you must be sure that your design is professionally made.
