Surface mount technology in PCB

Comments Off

PCBs are an innovation. PCBs have made circuits sturdy, small and neat as compared to early boards. This is the through hole technology of PCB fabrication. With time and requirement, the size if the PCB started appearing bigger. As this is an era of miniaturization, further reduction in size of the PCB was required. To cater to miniaturization of the circuits, surface mount technology came into effect. The components lack leads and can be soldered on the same side of the board where the circuit is.

Features of the surface mount technology
As the name suggests, components are placed on the same surface where the circuit design is soldered. This saves the other surface of the PCB substrate and it can also be utilized to design a circuit and placement of circuit components. The circuit components for surface mount technology are different from conventional components. They are flat profiled, small and give minimum height and length to the circuit.

A metallic bed is prepared for them on the circuit. The components have metallic ends. The components are placed on the bed and are soldered on the same surface. Even though they are on the same surface, a few holes need to be drilled on the board to connecting the circuits through on the two surfaces. These are called vias. They are useful in expelling heat from a circuit.

Circuit components are designed specifically for surface mount boards, ICs, resistors, capacitors, etc. all come in a very miniature and small flat profiled form. The main and the basic motive is to minimize the circuit.


  • The technology has become possible only because of the flat profile and small components. This has resulted in massive miniaturization of the circuits due to small component size, high density fabrication and utilization of both sides of the PCB substrate.
  • The data speeds are very good in surface mount technologies due to small track lengths and good circuit design.
  • The cost of production is low. Mass production of the components can be done and only few holes need to be drilled on the boards.
  • It offers less resistance to shocks and vibrations due to less height of the boards.
  • Low RF leakage and inductance at the soldering ends.


  • Reliability of solder joints is a major concern. With the miniaturization, soldering area is becoming minimal. They can also be damaged by impulsive jerks and potting compounds while thermal treatment.
  • These boards are not compatible with breadboard sockets. Hence they are not friendly to test.
  • They are not suitable for high power applications.
  • Skilled operators and workforce is required to tackle the problems associated with surface mount boards.

Technical Features and Advantages of a ‘V’ Engine

Comments Off

The V-type of engine has two rows of cylinders at an angle usually of 90 degrees. The working of a V engine is similar to that of a flat engine except the angle. Different angles of a v-type engine gives rise to different levels of smoothness. Some steep angles of the engine combines the advantages of V and flat engines and also the disadvantages.

Its advantages are its short length, the great rigidity of the block, its heavy crankshaft, and attractive low profile (for a car with a low hood).

Since it is short, it is compact and can be mounted easily. It is desirable in a vehicle with a small hood since the engine can be fit without negotiating passenger space. This engine lends itself to very high compression ratios without block distortion under load, resistance to torsional vibration. In-line engines have cylinders arranged, one after the other, in a straight line. Overall, V type engines are better and more powerful.

V engines are both used in cars and motorcycles. It is a highly preferred one in motorcycles due to its compactness.


V2 (V-twin): Has two cylinders mounted in a ‘V’ shape. Most of The V-twin connecting rods share the same crank-pin. The cylinders can either be off-set in two different planes or can be set in the same plane using the ‘fork and knife’ connecting rods.

V4: V4 has been used in vehicles very less compared to the other V engines. The only advantage it has is that it is small in size and still can produce 140 horse power.

V6: The V6 has 6 cylinders, three of them joining the other three at a right angle or an acute angle. Like all V engines, all the pistons rotate the same crankshaft. It is a commonly used basic configuration of engines in modern cars after straight-4.

V8: A V8 can be defined as two sets of straight-4 cylinders acting on the same crankshaft. They produce more power compared to a V6, but has the disadvantages of being costly and consumptive on fuel.

V10: A V10 is two straight-five engines coupled together. V12 is slightly more complicated and runs more smoothly, while a V8 is less complex and more economical. V10 is not found much in common purpose in cars, but highly used in F1 racing.

The other V engines are V10, V12, V14, V16, V18, V20 and V24 as of today, where the number after ‘V’ indicates the number of cylinders.

The Blind Spot Detection and Warning technology

Comments Off

This system consists of two radar units and it is similar to lane change assistance system. This technology devices are mounted invisibly to the corners of the rear bumper. From those two radar units one will operate as a system master and the other is configured as a slave. With the help of private data link, the data of both the radar units will combine with the sensor data fusion tracking algorithm.

On the sides of the car, the two radars are pointed well and this will detect the moving vehicle beside the car fitted radar. The area that contains five lanes is scanned. Compared to the lane change assistance systems, the range of the rear is shorter, but this BSP is very easy to install and lower in cost. So, this will optimize for the freeways and slow speed urban driving. This system gives very low false alarm rate and performs excellently.

This system performs, objective to lane mapping, tracking, the warning algorithms and detection algorithms and the extra customer code can also be integrated. This system requires no extra control units. This cost efficient master slave and innovative system design interfaces all controls and indicators and performs all the functions and also communicates with the vehicle data bus.

This radar sensors monitor the space behind the road and alongside the car, also display the visual signal which is near the outside mirror. This is to indicate is their any moving vehicle in the blind spot.

This system can withstand strain and monitors the areas that are difficult to see to avoid the hazardous situations to the driver. Read the rest of this post

WAN Optimization Accelerates Application Performance

Comments Off

Faster application performance ensures that a business effectively renders quality services to its employees and customers. WAN optimization is essential to businesses that are using network applications at its headquarters to stay in touch with branches at remote locations through WAN. WAN optimization enhances the application performance by techniques like bandwidth management, caching, compression, and Protocol optimization and significantly accelerates application performance.

Improves Productivity
Slow speed of application performance really hampers the employee productivity and customer satisfaction. Use of WAN optimization techniques accelerates the applications over the WAN, speeds up the data transfer and reduces the end-user application response time. This in turn makes transactions faster thereby leveraging the employee productivity. WAN optimization reduces the time taken to complete repetitive operations and helps in increasing employee productivity.

The employees waiting for long time to get a transaction done or download a file can not give prompt service to the customers and it results in unsatisfactory customer experience. By eliminating the network problems and reduced throughput, the remote employees can access the network applications that are installed on other locations at a faster rate. Accelerating the applications over the WAN also helps the mobile workers making it easy for them to cater their services to consumers.

Reduces Bandwidth Cost
Using WAN optimization techniques like bandwidth management/QoS, caching, compression, and Protocol optimization can significantly reduce the usage of bandwidth which in turn pulls down the network costs.

  • In Bandwidth Management, limits are set on network applications as to how much bandwidth they can use. This ensures maximum utilization of existing bandwidth by critical applications without providing additional bandwidth, saving considerable amount of money.
    In Caching, the copies of important files are stored in multiple locations. The users need not have to download these large files every time thereby reducing the bandwidth utilization.
  • Protocol optimization decreases the transmission delays thereby increasing overall speed of transmission and transaction response.
  • Compression techniques help to reduce size of the data thus saving time of transmission. Compression helps to send data in a faster way thus increasing reducing load on communication links.
  • Compression and caching together help keep the communications link uncongested and reduces queuing delays.

All these factors reduce bandwidth usage which in turn reduces cost. WAN optimization allows users to access WAN applications at speeds similar to a LAN.

WAN optimization accelerates application performance by eliminating issues like redundant file transmissions, chatty protocols, network latency, packet loss etc. WAN optimization ensures consolidation of IT infrastructure of the business at remote locations thereby ensuring higher productivity at remote offices. Using WAN optimization, the businesses can reduce remote office infrastructure cost by effectively centralizing applications, data storage, and server at data centers.

WAN optimization techniques increases transaction speed, improves productivity, and reduces bandwidth cost enabling businesses to be competitive and focus on newer markets. WAN optimization implementation helps businesses to get excellent ROI on their investments by reducing bandwidth costs and improving overall productivity.

Small Businesses Spend Too Much on IT: A Survey by Brother

Comments Off

As per a report commissioned by printer manufacturer Brother, small businesses are spending more than required on IT because of short-term thinking and also due to lack of computing knowledge.

As per the survey by Brother, small businesses are investing on cheap hardware for making short-term savings, but they had to pay higher costs in the long run. The small and medium sized enterprises are just thinking of the short term savings and are not concentrating on the money they have to spend later because of the low quality of the hardware. One of the other reason for purchasing low quality hardware is a false economy. The higher quality of the equipment could increase the productivity and ultimately the revenues. This is because of the tech journalists, bloggers and analysts who were the contributors for the report asserted. The larger corporations have IT directors who will be responsible for IT strategy. Only few small and medium sized businesses appoint a specialist.
