Computer Manufacture, Assembly and Quality Control

Aug 17, 2007
In today's world, computer training is almost in every case a necessity if you want to get a good job. The market for computer products is a multi-billion dollar business where one can find a perfect balance of technology and efficiency. In the world we are living in, computers are used for a variety of tasks and play a crucial role in the areas of academics and business.

The steps that are taken to bring the computer from several small components to a desktop product are organization of the manufacturing facility, assembly of hardware, installation of software, and a test process. The production of a high quality product is important to computer buyers.

Computer companies have several manufacturing facilities around the world where thousands of computers are built. Manufacturers try to make the best computer (in a given price range) for the lowest cost. Once a specific model is designed the company orders the high quality parts from their own component manufacturing divisions or outside suppliers.

Inventory control is an important part of acquiring components as, to remain efficient, the company tries to avoid overstocking. Manufacturers take note of the consumer demand, on a daily basis to efficiently establish quantities for the production line.

When assembling a computer, there are 8 to 10 major components installed including the processor speed chip, the motherboard, RAM (Random Access Memory), diskette drive, modem or network card, video card, hard drive, sound card, and DVD-ROM. Before the components are placed into the computer, each part undergoes an extensive testing process called "quality control."

Quality control ensures that faulty systems are not shipped. As an initial step, prior to the assembly process, an inspection of the outer case to ensure that there are no scratches or defects. The brand name and indicator labels are put onto the computer case at this time.

Next, the motherboard is installed and prepared for the processor chip. The chip (which is the brain of your computer) is attached to the motherboard along with the RAM component. Once the chip and RAM are installed, the internal speakers and sound card are placed into the case.

The hard drive, disk drive and DVD-ROM drive are in snuggly attached to the computer chassis. All these components are then attached to the motherboard with cables so that they may communicate with each other.

Power supply is then applied to the computer and other additional components such as the video card, and modem are added near a final stage of assembly. After all these components are installed to create the finished "PC," the unit is thoroughly inspected to ensure that all the cables connections are in place and all other defects are fixed.

Inspectors also make sure that cables are in appropriate places so that they do not touch components. This is important as heat given off components, while operating can cause minor explosions. The CMOS (complementary metal-oxide semiconductor- circuitry for the memory and processor) is set up at this time. The top cover is placed onto the computer and it is shipped off for further testing.

The utility of the computer and subsequent consumer demand for improved models will keep pressure on manufactures to build more efficient, high quality machines in future years. And if you haven't already started it yet, it's time for your computer training.
