Printed Circuit Board – A Brief Note About It

What Is A Printed Circuit Board?
A printed circuit board is basically an electronic board used for placing the different elements that conform to an electrical circuit which contains an electrical interconnection among all of them. They are characteristically made of plastic laminates with soldered chips, components, metal circuits, cables and sockets.

Types Of Printed Circuit Board:
The simplest PCB is the one that contains copper tracks or interconnects only on any one of its surfaces. This sort of circuit board is known as 1 layer PCB but the most common type is the one that contains 2 layers, as it facilitates you to find interconnections in both the surfaces of the board. However, depending on the complexity of the layout of the PCB, it can also be manufactured of 8 more layers.

In today’s time almost all of the electronic devices contain PCBs so as to provide the consumers an interactive and intelligent service. It can easily be found in a TV, computers, mobiles, washing machines, refrigerators, coffee makers and many more.

Prototype Printed Circuit Board - Vital Factors To Consider

If you are thinking of producing a prototype PCB, you have two choices; either you can manufacture it yourself or get it outsourced by a vendor who is well specialized in printed circuit board prototype assembly. Though there are two choices before you, but producing it yourself would require an assembly facility and an in-house PCB fabrication, which can never be a cost effective arrangements by any means if your requirement is only a prototype PCB. It not only sounds good but also makes better business sense to subcontract a Prototype PCB manufacturer who specializes in the particular field with an experience of long years.

Let’s have a look at the primary guidelines for choosing a vendor to outsource this electric device:

• Online Quote Convenience: Manufacturers who possess an Online Quote Convenience can save your time. The online system is simple to use that allows you to enter the salient details of the product’s design needs such as production specifications, thickness and the type of material. The ultimate purpose of the quote system is the cost control.
• Lower the Costs: It is typically less expensive to manufacture a huge quantity of circuit board than a small quantity. Though prototype is usually produced in small quantities as the design of circuit is still being refined. A vendor that has been in this production knows how to keep your cost low because it has the potential to distribute the cost of production and minimize the costs of assembly set up by spreading the production job among various clients so as to maintain the total cost.
• Package Types: You need to have a close look at the extent of package types that the prototype printed circuit board manufacturer accept for production. The quality vendor lists this crucial information on his or her website. By contacting technical support team of these manufacturers in order to verify their capabilities to assemble the prototype PCBs, you can steer clear of problems prior to the initiation of production.

These are the 3 main factors a PCB designer needs to mull over while outsourcing their designs to a Prototype PCB manufacturer.

Understanding The Significance Of Prototype PCB To Design Hardware

Circuit prototypes help smooth out the development process, allowing products to be created cheaper, faster and more successfully than shotgun roll-outs.

Prototype printed circuit boards are an essential and important step in manufacturing of Printed Circuit Boards (PCB).  With the help of Prototype, designers can easily understand the inconsistencies in design and function of PCB.  If you want to know the importance prototype PCB, then this article is for you.

Importance of Prototype PCB

While designing any type of hardware, most of the manufacturers ask for a prototype of the PCB. After building one, you will realize that you need many prototypes for perfect designing of hardware. Some of the importance of prototype are as follows:

• ·         A prototype will allow you to understand the flaws of hardware design. Though it is not same in case of software. These might not be apparent when working on software. But while designing hardware, you will be able to understand about physical limits of your design, and construction process.
• ·         You can integrate a Prototype PCB in your application to see its function. After that you can check if it is perfectly well-suited with your hardware or not.
• ·         Also, it will enable you to accept user input.

After manufacturing a prototype, you will be able to understand the flaws of PCB. And, this will help you to create a perfect product.   Name of first prototype is ‘crude prototype’ – it helps you to understand the physical properties of PCB. The second prototype is ‘working prototype’ which help you to test the functions of hardware. After all changes included, a final prototype is manufactured. The design of the last PCB is based on the design of the prototype.

Things to consider before ordering prototype

If you are planning to order PCB make sure that the manufacturer is able to meet your expectations. The manufacturer should have latest technology and can build one PCB in 24-48 hours. Today, there are many companies which manufacture prototype PCB; with the help of internet you can find the best one and get in touch with the professionals.  

Important Factors to Choose the Best PCB Manufacturing Company

A PCB Manufacturer Provides Multiple Layer PCBs

A PCB generally has a layered structure. Usually there are copper layers and insulating layers. The PCB manufacturer uses copper finishes which are on the surface of the PCB. If they are left exposes to the atmosphere and unprotected, they tend to oxidize leading to deterioration. Once it deteriorates, the PCB cannot be used.  In order to protect the copper surface, a surface finish is used which becomes and interface between the PCB and the component. The surface finish also provides a surface that can be soldered when the components are being assembled onto the circuit board.

Printed circuit board services include manufacturing the boards. There are several types of board including single layer, double layer and multiple layer PCBs. The single layer PCB has only one layer of the copper foil. The double layer has two layers of the copper foil which are layered one on top and the other one on the bottom. If the two layers are not enough and more are needed then they will be added in pairs. After the double layer will come the 4 layer and then the 6 or 8 or 10 layer PCBs. A Multilayer PCB can have as many as 32 layers.

There are many prototype PCB manufacturers available and all of them follow the same structures of making PCBs. There is the non-conductive material also known as the insulative substrate which is generally made out of epoxy and fiber glass. This substrate comes in several different thicknesses that range from 0.005 of an inch to 0.038 of an inch. The conductive layers on the other hand are made of copper. If you are looking to have a 2 layer PCB made, you can have it done in 72 hours. A 4 layer PCB takes a little longer, about 1 week.

The program managers have a good understanding of the importance of lead times and will ensure that production of your PCB is completed on time. Orders are scheduled in order to ensure that there is no delay and in the event that your order is urgent, the program manager will work closely with you giving you the best solution possibly while ensuring that quality is not compromised. 

Printed Circuit Board Products and Its types of Finishes

PCB stands for Printed Circuit Board which is responsible for physically supporting the circuits and wiring of any electronic goodies. It has a print of circuits embedded on it which are done by a conducting material, so it seems that it is printed but the board is highly conductive and helps in making an electronic gadget work.

The sole purpose of PCB’s are to provide a solid base so that the wiring can sit on it perfectly and in the same manner it can be put inside a machine. Every electronic device from parts of a computer like graphic cards, mother boards, to home appliances like washing machines, microwaves, fridges and television are wired on a printed circuit board.

These are called “printed” because they have circuit marks, conductive traces and vias on them. A “via” (Latin for path or way) is an electrical connection between layers in a physical electronic circuit that goes through the plane of one or more adjacent layers. A “via” is a small opening in an insulating oxide layer that allows a conductive connection between different layers.

There are different types of PCB factory which provides PCB on the basis of different conductive material used:
• Silver PCB: it is used as silver is highly conductive and the coats the copper from getting oxidized.

• Electroless Nickel immersion gold PCB: It has two layer of metallic coating over catalyzed copper. Gold protects the nickel from oxidation during storage and provides low contact resistance.

• Organic Solderability Preservative PCB: protects copper from oxidizing before assembly and is very thin at the range of (100-4000 Angstroms).

• Sn/Pb Hot Air Solder Level (HASL) with SN100CL alloy PCB: contains 63% tin and 37 % lead. The common thickness ranges from .00003” - .0015” (30-1500 µ”) and the melting temperature is 183 degrees C.

• Lead-Free HASL:  same process as the previous one, common alloys used are Sn/Cu/Co, Sn/Cu/Ni/Ge. It is slightly more uniform than the sn/pb one and has a higher melting temperature of 228 degrees C and thickness ranges from .0003”-.001” (300-1000 µ”).

• Immersion (White) Tin: it is formed with the intermetallic joint of copper/tin best used for backplane panels.

• Immersion Silver: it has the metallic solderability preservative with 8-15 micro inch of sheer silver and has an excellent solderability and can be easily bonded with aluminum wire.

• Electroless Nickel Electroless Palladium Immersion Gold (ENEPIG):  layer from 120 – 240 µ” of nickel is deposited on copper and is the fastest growing surface finish as it forms solder joints with SAC solders.

Support of a printed circuit board

A printed circuit board (PCB) is the board base for physically supporting and wiring the surface-mounted and socket components in most electronics. It mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. 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 most often green but they can come in any color.

Purpose
Printed circuit board supports the wiring done in an electronic device. The sole purpose of PCB’s are to provide a rigid base so that the wires and connections can sit on it firmly and in the same fashion it can be put inside a machine. Every electronic device from computer parts like graphic cards, mother boards to home appliances like toasters, microwaves, fridges and television are wired on a printed circuit board.
These are called “printed” because they have circuit marks, conductive traces and vias on them. A “via” (Latin for path or way) is an electrical connection between layers in a physical electronic circuit that goes through the plane of one or more adjacent layers. A “via” is a small opening in an insulating oxide layer that allows a conductive connection between different layers.

History
Printed circuit boards evolved from electrical connection systems that were developed in the 1850s. Metal strips or rods were originally used to connect large electric components mounted on wooden bases. In time the metal strips were replaced by wires connected to screw terminals, and wooden bases were replaced by metal chassis. But smaller and more compact designs were needed due to the increased operating needs of the products that used circuit boards. In 1925, Charles Ducas of the United States submitted a patent application for a method of creating an electrical path directly on an insulated surface by printing through a stencil with electrically conductive inks. This method gave birth to the name "printed wiring" or "printed circuit”.

Method of production by PCB Manufacturer
Components on a printed circuit board are electrically connected to the circuits by PCB manufacturer using two different methods: the older "through hole technology" and the newer "surface mount technology." With through hole technology, each component has thin wires, or leads, which are pushed through small holes in the substrate and soldered to connection pads in the circuits on the opposite side. Gravity and friction between the leads and the sides of the holes keeps the components in place until they are soldered. With surface mount technology, stubby J-shaped or L-shaped legs on each component contact the printed circuits directly. A solder paste consisting of glue, flux, and solder are applied at the point of contact to hold the components in place until the solder is melted, or "reflowed," in an oven to make the final connection. Although surface mount technology requires greater care in the placement of the components, it eliminates the time-consuming drilling process and the space-consuming connection pads inherent with through hole technology. Both technologies are used today.

Two other types of circuit assemblies are related to the printed circuit board. An integrated circuit, sometimes called an IC or microchip, performs similar functions to a printed circuit board except the IC contains many more circuits and components that are electrochemically "grown" in place on the surface of a very small chip of silicon. A hybrid circuit, as the name implies, looks like a printed circuit board, but contains some components that are grown onto the surface of the substrate rather than being placed on the surface and soldered.
