The Best Way to Save Time in Rapid Prototyping

Rapid prototyping help ensure that your work is being headed in the right direction and quickly let you share the exact development of the product with your teammates and customer without investing in the actual development of the project. No matter what product you’re working on rapid prototyping helps you in almost all type of projects. Rapid prototyping plays a crucial role in hardware design and software design as well where a prototype is built before the actual crafting of the product this is done to reduce costing and work overhead in later stages of project development. 

There are some vital points worth considering in order saving time in rapid prototyping:

1.Think of rapid prototyping as disposable 

Rapid prototyping offers you an exciting level of freedom. The main goal of rapid prototyping is to gain feedback for the final product. With small efforts, you can build your product without any risk. Consider a case you are working on a project and when the project reaches its final development customer asked you to bring some changes in the project. Imagine how pity it would be. So the prototype or dummy of the desired product s created first so that initial changes can be easily incorporated. It simply acts as disposable once the actual project is developed. This makes rapid development of the desired product.

2.Establish the clear purpose of each prototype:

Product prototype starts with clear objectives and relies on several steps, it starts with requirement gathering and rapid prototype helps you grab customer feedback and help quickly convey plans and share new ideas with prospects. This helps you make clear project scope and level of fidelity.

3.Define the prototype’s design early:

An early design of prototype could land you in the safe state and free from future stress. It develops clear scope via different approaches.

4.Keep flat design as long as possible:

As you know last minute design can create a ton of work if you build final interaction too early. Attention to UI increase as the deadline approaches. Issue a final call before start building the actual product. This makes you feel heard and stay focused on initial design rather than the rebuilding of the prototype.

5.Perform comprehensive testing before final prototype:

You never know which part of the prototype causing bug into the system so perform unit testing as well as the proper audit to find the lacking site. It is always advised to use proper audit means to assess the prototype layer by layer.

6.Don’t expect all your prototype edge leads to development:

In rapid prototyping, sometimes few points take an unhappy path to the customer. However it should be well designed and separate development specification make the most sense. 

Keep your rapid prototyping rapid for better outcomes, it helps you customer feedback collection and improve the blind spots in the prototype and perform series of enhancement in the prototype for better final development. By following points, you can save time in building your prototype.

Everything You Need To Know About PCB Manufacturing!

The demand for PCBs (printed circuit boards) will seemingly not decrease in the near future; futuristic mobile phones, BluRay disc players, plasma TVs, electric cars have all made certain of this. PCB manufacturing technology is also not relenting and is up to date with modern electronic goods requirements. As an electronics manufacturer, we simply cannot be ignorant of modern PCB tech - the varieties of PCBs being as many as they are representative of the numerous modern PCB techniques and processes only recently developed. The design and manufacture of PCBs should be left to companies equipped with the latest of PCB equipment used in the prototyping and actualization phases.

PCB manufacturing can be divided into manufacturing the boards with or without components. Blank PCBs can be single or double-sided. Different PCBs have different capacities. We can have multilayered PCBs manufactured via techniques such as PCB milling, copper etching, screen printing etc. Most PCB fabrication companies also offer prototyping services - this involves developing a working PCB model before actual mass production can commence.

The raw materials used in PCB manufacturing are varied but copper is the basic material. Copper is always coated using a tin-lead combination to protect it against oxidation. The industry standard for PCB contact points is copper covered with this lead-tin combination, plated with nickel, and finished off with gold to maintain excellent conductivity. The quality control considerations that the manufacturer works by are a point to look out for. This involves the various visual as well as computerized scrutinies of the printed circuit board manufacturing steps from the conception to shipping stages. It also details the steps taken to rectify flaws and faults in the process.

PCB board manufacturing can be a very harmful process both to humans and the environment. This is especially so where the element Lead is present. A PCB manufacturing plant should be able to clearly define the safety considerations it has in place to deal with toxic matter, ways of disposing of obsolete PCBs, the recycling processes, and the modern human and environmentally-friendly equipment and processes they have in place.

The manufacturing process deployed is crucial as the working of the PCB and therefore the different equipment used in PCB manufacturing are complex and sensitive. The fabrication environment is also a controlled one so as to prevent the PCBs from any contamination. Your PCB firm of choice should be able to guarantee this even for the final product packaging process. Ignoring this is equal to putting your company and its electronic products' reputation in jeopardy. When partnering with a PCB manufacturer, it is important to choose a firm with extensive experience. As a customer, you should also be verifying if the firm has a proven track record.

What is PCB and what is the use of PCB layout?

PCB stands for ‘Printed Circuit Board’ and it is used for high volume production without an expensive environment. Its main use is to connect the electronic components manually. PCB products are used in simple electronic products and are best used to connect electronic components using constructive tracks onto a non-conductive substrate. PCB can be of different types - single copper layer, double sided copper layers, or multi-layers which will have outlet & inner layers. What does it do? They allow higher component density in the primary insulating substrate.

What is PCB Fabrication?

First, the designing of the PCB is done and a prototype PCB plays a critical and significant role in the creation of its design and manufacturing. Also, if there is any problem in the designing phase or if any changes are necessary for the design of the PCB prototype, then it can be done easily. A fresh prototype is created and supervised in case of any failure during the overall procedure. The entire process of PCB fabrication includes steps like - etching, multi-layer processing, masking, drilling, engraving photos, finishing and finally electrical testing.

PCB Testing

PCB testing is done to check the efficiency of the board and the test plays an important role in the completion of the process. To make the PCB function well and perform outstanding well, it used different types of specifications like Arlon using for longer life in high temperatures and for flexibility, polyimide is used. Has the test turned out to be negative? Replace or repair the entire board effectively. It will help incorporating advanced circuits to exhibit at PCB.

Provided here are some of the efficient tips in the PCB Layout

PCB layout ensures that the prototype PCB is functional after the fabrication process. The process gets neglected due to most of the attention of circuit formation. Consider the tips for improving the efficiency of the PCB layout –

Sizzling Traces: It is used in PCB assembly for higher resistance and the two points connect within the PCB. With the use of length, width, and thickness, the resistance of the trace is controlled.

Make Smaller Loops: Larger loops are made small as smaller loops have lower inductance. It spikes the result from a PCB, with reduction of an amount of higher frequency voltage.

Decouple Capacitor Placement: If the capacitor is placed near the power and ground pins, it results in an increase of efficiency.

Keep Noise Traces Away from Analog Traces: The doubling of the signal on the traces are the result of the placement of 2 types of traces.

There are many prototype PCB manufacturer who develops efficient circuit boards. These manufacturers are known for developing prototypes which serves the best interest in getting the fault-free final product.

Facts You May Not Know About Print Circuit Boards!

It has been well established that prototype printed circuit boards are a very complex puzzle in themselves. Their usage is of a variety and they come in different sizes that depend on the use of it. And one thing is fixed for it, that it’ll always be an amalgamation of different components to come together for its assembly. 

Putting all these parts together can be a bit time taking and complex but we can break it down into the most common components to further understand its uses.

If you’re familiar with the purpose of prototype printed circuit boards or PCB fabrication, you probably know how commonplace and necessary they are in today’s technologically dependent world. But even though printed circuit boards are found in almost every device we use on a daily basis, you might not know these four amazing facts about PCBs:

1.Some gramophones had printed circuit boards.

If you come to think of it, prototypes PCBs aren’t something that is entirely a new concept. They were there is early 1900sand after that too. And they were used in a few gramophones and also tube radios. They might not look similar to the printed circuit board prototypes that we are used to seeing now, but no matter what the format was, they helped in bringing entertainment and new developments into our homes like they do today.

2.The first PCBs were funded by a music printing company.

Father of the Modern Printed Circuit Board, Paul Eisler escaped the Nazis, and he was an inventor from Australia. He worked at a music printing company and shared the idea with everyone of a new invention.  And that was to make the first printed circuit board prototype. So, the company decided to invest in his idea. Today we see the results of his hard work as the prototype printed circuit boards.

3. No one knows why they’re still green.

The green material that is used on the layout of the PCB is a solder mask that’s visible through the glass. But nowadays technology has improved; solder masks are available in various colors. But the question remains that, why is the board still green then? Some people believe its story goes back to the military reigns and some also say that unlike that belief it was just about being uniformed. The companies just wanted stick to their idea of convention and continue with the original color. But then the legacy does continue and we stick to have the color green with us till date. 

4. PCBs are vital in space travel.

Not a lot of people would know this, but as being an integral part of NASA’s space program, these circuit boards did help in getting the Apollo 11 astronauts to the moon and back safely. These boards are ideal for difficult electronics, given that they are light weight and need a very small amount of energy.  

Although we live with an assumption that the technology we see and use today is brand new, the fact remains that they go long back in time and have a very fascinating history to them.

How Printed Board Circuit works and how to get an efficient PCB layout?

Printed circuit boards are used in simplest electronic products and it connects electronic components using conductive tracks, pads and other features onto a non-conductive substrate. Advanced PCBs contain components embedded in the substrate and components are generally soldered on the PCB. It can be single sided which contain one copper layer, double sided which contain two copper layers, or multi-layers which will have outlet & inner layers. Multi-layer PCBs allow higher component density and FR-4 glass epoxy is the primary insulating substrate.

In simple terms, a PCB can be defined as a tool providing mechanical and electronic connections by routing signals & power. Before PCB, there used to be a wire-to-wire connection but the durability of the device can be problematic. With the increase in demand, these assemblies have become common now. Also, the use of smaller ubiquitous technology has made the system more cost-effective. PCB assemblies have an application in almost every electronic appliance like computers & printers, TVs, home appliances, digital clocks, and cell phones.

Tips and Tricks for an Efficient PCB Layout

The PCB layout is often neglected with the majority attention on the formatting of the circuits. It ensures that the prototype PCB is functional after the fabrication process. Look at some of the tips to improve the efficiency of a PCB layout –

Sizing Traces

A copper rack used in PCB assembly is high in resistance and it connects two points within the PCB. The resistance of the trace is controlled by designers with the use of length, width, and thickness. To provide different levels of thickness, designers use anything between one and six ounces of copper.

Make the Loops Small

Smaller loops have lower inductance and resistance and so large loops are made small as possible. The reduction of an amount of high-frequency voltage spikes results from a PCB with high loops.

Decoupling Capacitor Placement

Increase the efficiency by placing the capacitor near to the power and ground pins of integrated circuits. The placement of capacitors at a distance results in a reduction of inductance ability.

Keep Noise Traces Away from Analog Traces

The placement of 2 types of traces will result in doubling of signal on the traces. Now those of you are not looking to keep the noise on the need to keep the high frequencies away.

Leave Room

Prevent the shock hazards by leaving the room between copper traces and fills. There should be a proper distance between the two if solder mark is not working as a reliable conductor.

Contact the PCB manufacturer for the effective design and preparation of rigid flex PCBs. PCBs are having high density to support new products and small packaging. Also, it has extremely thin feature if a circuit board reduces the bias force with a thin base pill. Also, flexible PCB has a high thermal transfer feature and it is resistant to heat. The most highly heat resistant FPC has reached 150 degree Celsius and reached a maximum temperature at 175 degree Celsius.

PCB the Soul of Contemporary Electronic Device!

There are hardly any devices which do not use the PCBs in contemporary time. A PCB is a thin board made of fiberglass, composite epoxy, or other laminate material. Conductive pathways are etched or "printed" onto the board, connecting different components on the PCB, such as transistors, resistors, and integrated circuits. Electronic components are usually placed by machine onto a finished PCB that has solder dabs in place. The PCB bakes in an industrial oven to melt the solder, which joins the connections. It is found that the most PCBs are made from fiberglass or glass-reinforced plastics with copper traces.

Use of the PCBs in the computer, laptop and many other devices-

PCBs are normally used in both desktop and laptop computers. They serve as the foundation for many internal computer components. There is the use of the PCB in the video cards, controller cards, network interface cards, and expansion cards. These components, all connect to the motherboard, which is also a printed circuit board.

The PCBs are widely used in many other electronic devices besides the computers and laptops.  The common household appliances like TVs, radios, digital cameras, cell phones, and tablets include one or more printed circuit boards. The PCBs, which are used in mobile devices look similar to those found in desktop computers and large electronics, but they are typically thinner and contain finer circuitry. PCBs can be single-layer for simple electronic devices. Printed circuit boards for complex hardware, such as computer graphics cards and motherboards, may have up to twelve layers.

PCBs are of following two types. Let’s compare them- 

• Single layer PCBs- The single layer board is the least complex option and includes a one-sided layer of substrate. This board is built with the electrical components and parts attached to one side and on the other side there are the copper traces. The copper is used due to special reasons because it is a great electrical conductor. This copper layer is usually protected by a special solder mask. There is the silkscreen coating is a further feature to help mark the different components on the board. It is a useful board for the most basic electronics and will be used by the at-home hobbyists in their first electronics projects. This kind of board is relatively low-cost to PCB Manufacture compared to the multilayer. This simple designing is the reason it has plenty of limitations and is far from being the most used in the industry.

• Multilayer PCBs- Now we come to the multi layered boards which are built with two or more layers. These layers are separated by insulation. The standard size is in the region of 4 to 10 layers, even though there are boards with up to 42 layers. This is type of boards are preferred very much, especially for the most complex electronic configurations. The different boards are connected using wires passing through the individual holes. Space and weight of these boards are lesser than the single layer boards. These boards are used in handheld devices, space probe equipment, medical machinery, servers and computers widely.

Printed Circuit Boards Brought Drastic Change in Today’s Machinery!

Humans have shown extensive progress and have lifted themselves from the violent animal to civilized persons. Machines played a very vital part in doing so. Machines make our work easier and they reduce effort and time greatly. We are surrounded by the machines these days and most of our work is done by machines or by the help of the machines. There is constant up gradation in the technology of machines and new, faster, reliable and technologically superior machines are coming into the market. Most of the machines these days are electrically operated, for example computer. It is a very essential device which is used by almost every office no matter; it is private organization or government offices. We cannot imagine the human existence this time without the help of the machines.
