Surface Mount technology has emerged as a popular choice and has replaced the through-hole technology within the industrial structure. In the through-hole technology, the fitting components are constructed with wire leads put into the holes of the circuit board. SMT component is preferred over the through-hole substitute, since it is smaller in size. This is so because it has smaller or no leads in it. The pins or leads may be of various styles, viz. terminations on the body of the component, flat contacts, or a matrix of solder balls better known as ball grid array.

As mentioned above, BGA or ball grid array is the very packaging type used in surface-mount devices. These are used basically for integrated circuits. It provides more interconnection pins than a flat package or dual-in line. Instead of the perimeter, the whole surface of the bottom can be used in these types of devices. It also provides shorter leads than the ones in perimeter type, thus leading to a better performance with high speed. Soldering of these devices require precision. So, automated processes are used.

Advantages of BGA packaging:
•    provides high density
•    provides less thermal resistance between the PCB and package
•    the leads has low inductance

The SMT soldering process should be done matched with the design and specification of the device. X-ray inspection should be used to test the solder joint quality. 3D-X-ray inspection is done to detect the problems of BGA assembly on SMT soldering.

Through-hole technology had completely replaced earlier electronic assemblies until the advent of Surface Mount Technology (SMT). Through holes became Plated Through Holes or PTH for the electronic components to make contacts with the required conductive layers. In this technology electronic components such as pins and terminals were manually inserted and then soldered to pads on the opposite side. Automated insertion mount machines would also often be used in the process.  From rework cycles being factored in the PTH design, to a high amount of precision with cutting edge laser drilling equipment PTH PCB assembly services have to be top notch for them to perform well.

There are many electronic manufacturing companies which have a wide range of expertise when it comes to electronic assemblies. Sub contractors functioning within the ambit of the Electronic Manufacturing Industry have many PCB assembly services to facilitate the production and maintenance of a many companies. From testing conventional PTH PCBs to providing support for mixed surface mounted and plated ones there are firms which offer complete solutions to the electronic needs of their customers.

Some companies specialize in prototype PCB assembly. Once the designing of a PCB is done by the engineers, the designed PCB assembly is manufactured in order to test whether it functions in the required way. This is known as a prototype PCB assembly. After its testing, certain changes are usually made and a second batch of PCB is manufactured which meets majorly all the design requirements.

PTH or Pin through Hole PCB assembly uses designated holes in the board through which the components are soldered. This is used to manufacture products which have no space constraints or when the components are cheap. This is the conventional type of PCB assembly process.

Surface mount assembly is a technique of assembling electronic circuits in which components are soldered directly on the surface of bare printed circuit boards instead of wiring them through holes. The general term SMT is used for all the process regarding surface mount technology. SMT PCB assembly process typically includes screen printing with solder paste, placing components and soldering them with the help of a reflow oven.

Importance of Functional Testing of PCBs

Functional testing, as the name suggests, does not look into the placement of parts or presence of the various components that go to make a PCB. It looks into the overall functioning of the PTH or SMT PCB Assembly simulating the very environment where the product will be ultimately used. Whether the PCB is going to be placed inside a computer modem or a mobile phone, the exact configuration and slot is mimicked and electricity is passed to check out whether the PCB is functioning just the way and with the same pace it should. Contract manufacturers of repute like Denis Ferranti employ avant-garde equipments and strategies for testing PCBs in view of keeping up with client expectations and maintaining high standards.

Strategies of PCB testing

A number of strategies are used to check the functionality of PCB assembly devices. Some of them embrace PCB In-Circuit test, PCB AOI test, PCB Flying Probe Test, PCB X-Ray test and PCB JTAG test. Among these, PCB In-Circuit tests are most widely used as they look into every component post soldering individually to detect any flaws. However, this is different from Functional Testing which is a more advanced method and has found preference with many reputed manufacturers.

How is Functional Testing Carried Out

The whole process of a Functional Testing along with the needs differ from one PCB to another. Reputed contract PCB assembly manufacturers like Denis Ferranti Electronics possess avant-garde equipments for implementing the tests to the core. In general, Functional Testers are connected to the PCBs via a test-probe point or the edge connector. The test also varies according to the final environment or appliance where the PCB will be used and hence emulates the very electrical ambience as a measure to check the proper functioning of the PCB assembly. The testing program then undergoes a thorough checkup through a sequence of codes to ensure that every part of the assembly is working fine.

Advantages of Functional Testing

The advantages which Original Equipment Manufacturers can get by partnering with contract manufacturers for PCB assemblies like Denis Ferranti for such Functional Testing are many. Such contract manufacturers are equipped with modern accouterments for testing PCBs of different kinds and catering to a number of electrical environments. This turns out to be economical and time-saving for OEMs who do not require splurging on purchasing resources and equipments for detailed testing. In depth Functional Tests undertaken by adept engineers label the products as tougher and free of flaws making other tests like ICT a cakewalk.

In product designing procedure, SMT PCB assembly helps outrageously in manufacturing. It helps to make the electronic devices work. With this, the need for creating holes on the device is eliminated. The circuit board is made up of non conductive materials however when etching or printing has to be done on the surface, then the use of conductive materials like copper is implemented. The SMT PCB assembly is available in two major types. One is rigid and the other is flexible. One of the major reasons to use SMT PCB is, under the surface of the PCB is, it frees up the space for other purposes. It also gives significant cost benefits if ordered in a large number.

The usage of the modern machines in different part of the making processes is also an essential thing that is making the electronics work go smooth. A new idea that has really made the market bigger is the SMT PCB assembly system. With the Conventional Lead-use Technology, the things were quite tougher to develop and now that the use of U-Hole techniques and modern machines are immense, there has been a change from the basic level of the manufacturing if the SMT PCB assembly. Again, physical hardships are reduced as the selective wave and the Inspection methods are now in use that affects the preparation in a better accurate way.

An idea on the electronic manufacturing services: The system of the manufacturing services in regard to electronic chips and boards, the manufacturing services and the way this has developed through ages can not be over-looked. In fact the modern day assembling is much dependent on the manufacturing of the right board and the chip construction materials are also an important factor for the services to do well. The exact level of accuracy is determined by the way these chips work and the major function of the electronic manufacturing services is to get the electronic component work in their maximum functionality. The system is worked as a whole on the idea of testing things, making them to work and repair if damaged. So, in any way there is no chance the role of the electronic services can be avoided.

Why SMT PCB assembly is advantageous: There are reasons why there is a stir with the development of the surface mount technology and the PCB assembling on it. The advantageous sides can not be neglected. The easier availability of the components makes the manufacturing easier. As well as there is a way of getting things at a cheaper rate the other forms of PCB assembly. The SMT PCB assembly help in better accuracy as the manufacturing is easier and there is a chance of getting things more accurate than other forms. Therefore, that gives the accuracy a better level to reach. As there is increased space, the holes are easily and add to another advantage of getting things less damaged as time passes and brings on the depreciatory losses.
