Quality and testing

Because Dane-Elec markets their products as a so called A-brand, they have to see to it that the products they manufacture are of an excellent quality. Making good memory modules starts of course with the components. Their suppliers are hand picked, instead of just looking for the lowest price. This goes not only for the memory chips itself but also for all other parts and of course for the CompactFlash cards. Besides choosing the right supplier, they also check every new delivery by placing a percentage of the delivery under a microscope to be sure the quality is at the desired level.

During the process of making memory, there are also various optical tests. Although it is unlikely that the very expensive machines make errors, there is always a small possibility of malfunction or human error. Using a special scheme, the person working on the machine checks to see if everything comes out all right.

The company owns highly advanced and automatic testing equipment, which is used to test a certain percentage of every order. The height of the percentage depends on how many experience they have with a certain product. If malfunctions are discovered in one of the shipments, they increase this percentage. With the help of a large database they can track where, when and by whom the product was manufactured. By combining this data with their own test results and the information gathered by their RMA department, they are able to pinpoint structural problems.

To test modules for which they do not have automatic equipment, or to test compatibility, they use a whole series of different computers. Old 486 machines, laptops and dual CPU servers are sometimes running Quake III for days and days. All this to be sure that things don't crash due to a faulty memory module.
