Kingmax microSD Cards

Kingmax is one of the world’s only memory manufacturers that possess IC packaging facilities, and Kingmax is also the world’s leading manufacturer of PIP packaged memory products. When used with very small surface area memory cards, PIP packaging provides incomparable performance and value. In addition to water and dust resistance (as well as heat and pressure resistance), microSD’s main advantage lies its tiny size. At the same time, the PIP packaging technology enables Kingmax to apply its distinctive red color, which allows consumers to know at first glance their products are genuine Kingmax memory products. Stacking technology is another complication for manufacturing microSD products, especially high capacity products. Because of microSD’s extremely small size, currently all microSD products are produced using stacking technology. Higher capacity cards such as the 512MB microSD cards are produced by stacking two 70-nanometer 256MB flash chips.

Mobile phones today are the symbols of the modern mobile digital lifestyle,
of which memory cards are an increasingly important element. Memory cards have
evolved from the early MMC and SD cards to the second-generation miniSD and RS-MMC
specifications, growing smaller, lighter and thinner while providing ever
increasing storage and flexibility for digital products. The third-generation
microSD cards have taken this evolution to the next step: nearly the size of a
fingernail (15mm×11mm×1mm), microSD cards are now the world’s smallest memory
card products.

In 2005, the SD association announced the microSD specification, the newest
member of the SD family. microSD is 100% compatible with the earlier T-flash
format, and due to its extremely small size, microSD has quickly gained
popularity among mobile phone makers seeking a smaller storage medium. These
factors have resulted in explosive growth in phone products that support the
microSD specification. Major manufacturers including Motorola, Samsung and LG
have all released microSD-compatible mobile phones, and according to the latest
“2005 Mobile Storage Products Research Report,” microSD (including T-Flash)
products accounted for 29.5% of the market share of mobile phones with memory
card support. Compared to two other mini memory card formats – miniSD and RS-MMC
– microSD’s market share was 1.6 and 10.5 percentage points higher. The microSD
format will clearly continue to take the mobile phone memory market by storm.

However, unlike larger cards such as SD or MMC cards, microSD’s surface area
restrictions make it impossible to use SMT production (the most common
manufacturing method for flash memory cards). microSD cards must be produced
using direct die packaging technology. Kingmax is one of the world’s only memory
manufacturers that possess IC packaging facilities, and Kingmax is also the
world’s leading manufacturer of PIP packaged memory products. When used with
very small surface area memory cards, PIP packaging provides incomparable
performance and value. In addition to water and dust resistance (as well as heat
and pressure resistance), microSD’s main advantage lies its tiny size. At the
same time, the PIP packaging technology enables Kingmax to apply its distinctive
red color, which allows consumers to know at first glance their products are
genuine Kingmax memory products.

Stacking technology is another complication for manufacturing microSD
products, especially high capacity products. Because of microSD’s extremely
small size, currently all microSD products are produced using stacking
technology. Higher capacity cards such as the 512MB microSD cards are produced
by stacking two 70-nanometer 256MB flash chips. Circuit paths are already quite
complicated in such a small area, and stacking two ICs makes the process even
more complicated. Therefore, memory makers lacking IC packaging technology face
many difficulties producing this type of memory card, and it is precisely this
technology that makes Kingmax one of the world’s only companies who can provide
a stable supply. With its patented PIP packaging technology and outstanding
quality and compatibility, it is no wonder that Kingmax products are the most
widely respected by electronics manufacturers and consumers alike.

Many of the world’s major mobile phone manufacturers have taken notice of the
Kingmax microSD cards and Kingmax has already begun receiving large orders and
forming partnerships to supply microSD cards to mobile phone companies around
the world. Through these partnerships, Kingmax will bring an all-new mobile
multimedia experience to consumers the world over.
