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.

Although you may be flooded with a number of companies undertaking electronic sub assemblies and BGA assembly services while searching online, how do you understand which is reliable? Indubitably quality of the products and services is one of the main criteria that need attention. As an electronic company having considerable experience in the field we undergo in depth testing of the final products and in case of any errors take additional efforts to rectify them. We also adhere to the standards for maintaining consistent quality as set forth by ISO 9001-2000. These regulations are further meant for environment-friendly considerations. While quality is important you cannot simply wait for months on end for your PCBs to be delivered.

Therefore, in order for timely delivery the professionals must work with speed, especially when bulk orders are placed. We, at Denis Ferranti are harnessed with avant-garde equipments which give out high-speed and quality turn-around production, ensuring timely deliverance of the products to our customers. Finally, last but definitely not the least the technical credentials of the engineers and PCB designers need to be enquired. Our team of technicians is duly experienced in designing, assembling, procurement and testing of prototype PCB assembly.

Initially, we had access to the conventional through-hole type of circuitry that came with leads which were directly connected through pre-manufactured holes in the PCB. Then we were introduced BGA, which stands for Ball Grid Arrays. BGA Assembly circuit boards use smaller circular balls that are soldered to offer flowing electricity through different parts of the circuit. This offered benefits to the PCB assembly. Most importantly, it offers higher density to the circuits. Initially it was difficult to solder the through-hole circuits accurately, as they were thickly populated. The chances of crossover or at times short circuits increased. With BGA assembly circuit boards, many connections were possible, in spite of the fact that they require machined soldering to gain accuracy. The other benefit of BGA circuits is that they allow easy transmission of heat from integrated circuits that reduce the problem of overheating.

Ball Grid Array abbreviates as BGA. BGA Assembly is equally important as electromechanical. The former plays an important part in fabricating as well as designing Circuit Board. Further, it even helps in identifying flaws that might have occurred in procedures between the chip and the circuit board. BGA inspection helps maintain the standards of Circuit Board designing by meticulously detection varied problems in the prototype. The inspection helps in identifying problems in large number during quality or development process. The possible problems might be cracked joints in solder, excessive flux, bridging, solder pads, joint cracking, non-contact, contamination, ratcheting, etc. It easily recognizes if there are any defects, which turn out to be cost saving. Manufacturing companies of circuit board assemblies mostly rely on BGA inspection for ensuring the reliability of joints while the circuit board is being fabricated. The inspection, further, finds out errors that are difficult to detect by traditional vision systems.
