The Nature Of Keypad Testing And Its Effects

By Lance Buschman


One does not quite know the process involved in determining whether a machine is manufactured to expected standards. Lack of proper testing may lead to frequent breaking down of the machine which will eventually cause problems for the owner of the machine. In different countries you will find that they have boards that carry out the testing of products and one such area of testing is the keypad testing.

As is expected the data entry buttons are very important as majority of commands cannot be given without these delicate but all important buttons. Examples of machines that cannot in any way perform without this aspect of the machine include computers as well as calculators and cellular phones.

In this day and age when everything is manufactured to be miniature, it is important to verify that all areas of a machine work to par. This is because the smaller a machine is; the harder the process of data entry is as well. To ensure a hundred percent functionality, every data entry button must be experimented on using a system known as activation force.

This system profiles individual data entry buttons available on the board according to the purpose for which they are created. Once profiling is done, a certain amount of pressure is exerted on the buttons and observations are later made in order to conclude whether the buttons are working efficiently or not.

In the process of exerting pressure, the manufacturer should be extremely careful because sometimes the force may be too much making it close to impossible for feeble people such as the elderly or the sick to use. The force should also not be too low so as to cause minor avoidable accidents such as when the gadgets are in the pocket where random calling or texting can be done

It is not difficult to come by the machines that allow the process of active force to take place. They can basically be found in all manufacturing companies that would need them . It is also important to note that most of the machines used in this purpose are electronic as it makes it easier to compare the effect of different amounts of force.

The electronic machine should also be manufactured in such a way that accuracy of the buttons can be determined without destroying the delicate keys on the pad. Keypad testing is therefore a very delicate process and should be done with utmost care to avoid these damages.
