WHAT IS SD CARD?
Secure Digital (SD) is a proprietary non-volatile memory card format developed by the SD Association (SDA) for use in portable devices. Secure Digital cards are small plastic memory cards used in a variety of electronics. Anyone who owns a digital camera has pulled an SD card with pictures out of their device, but the versatile cards can also be used in tablets, camcorders, cell phones and more. When SD cards break or the memory storage gets too small, you may be wondering how to recycle them. Like all electronics, it is important that SD cards get to qualified recyclers rather than just going in the trash. We share some ideas for recycling and reusing them.
MANUFACTURING PROCESS:
The card is made up of a single sheet 12 of flexible plastic material, for example polyvinyl chloride (PVC) of standard dimensions. The exterior of most SD cards is primarily plastic, although some have significant amounts of metal on the outside. Inside the SD card is a circuit board that contains precious and nonprecious metals. SD cards come in three different sizes: full, which are 32 by 24 millimeters; mini, which are 20 by 21 millimeters; and micro, which are 11 by 15 millimeters. While SD cards are small, it important to keep them out of landfills and incinerators. Metals like steel and gold are finite and can be reused endlessly (in the case of gold and other precious metals, they are also extremely valuable). The plastic covers of SD cards are made with petroleum products and will never biodegrade. And many times, there is nothing wrong with SD cards. They are being replaced because the owner gets a new device or wants a larger card. Make sure you get your unwanted but reusable SD cards into the hands of people who can use them.
Memory chips are manufactured on wafers at Micron facilities in Lehi, Utah. This clean room is 100 times cleaner than hospital operating room. It takes more than one month to manufacture a memory chip. Each wafer is moved through more than 800 different processes The manufacturing never stops – the facilities operate 24/7, 3675 days a year with thousands of employees. Micron technology is the only company that manufactures memory chips in the United States. The wafers are then sent to assembly plant in Asia. The chips are cut out from the wafer and assembled onto circuit boards. Cards are assembled using solid gold thread that is not much larger than the diameter of a human hair. Now it’s time to turn the chip into Memory cards and flash drives. We use very strict testing methods to make sure that you get the highest quality products. Products are assembled and tested by hand to assure the finest quality. Every products get tested before it shipping to the customer. Every speed-rated memory is tested to assure that it meets our speed specifications. Now it’s time to put the product into retail packaging. The products are then shipped all over the world. Then it is into the hands of consumer. Providing the high performance, high quality memory solutions that customers expect from Lexar.
USAGE OF ADAPTOR:
The adapter takes the micro-SD card into an internal slot and makes it appear electrically to be the same as a full-sized SD card, which is the exact same size as a full-sized SD card. That way, the latest small sized cards can be used in older equipment without manufacturing and stocking two cards. This benefits all the manufacturer, the retailer, and the end consumer. The adapter is very cheap and extends the contacts.
