Security solutions is an area that has benefited significantly from advances in semiconductor packaging techniques. This document provides an overview of the most widely used packages for semiconductor devices used in security solutions.

Packaging Techniques for Security Solutions Devices

The latest security solutions devices are increasingly using NFC (Near Field Communication), a standard which allows wireless connection and data transfer between two devices in close physical proximity to each other (usually, a few centimeters). NFC has already been implemented in mobile phones, primarily to enable mobile handsets to act as payment gateways, e-tickets, and let the devices act as "electronic identity cards” (such as a medical ID card).

Security solutions devices are most commonly offered in the FBGA (Fine-pitch Ball Grid Array) package, which offers multiple advantages, such as a thin and light structure, low profile (height), configurable ball pitch, and suitability for production on the mobile platform.

Security solutions devices are primarily available in two variants: a standalone solution containing an application processor (AP) and the NFC controller, and a security-integrated solution containing an embedded security element (SE) in addition to the AP and NFC controller. Figure 1 below illustrates the standalone variant of a typical security solution in an industry-standard FBGA package.

The second variant is a system-in-package solution containing a specific processor, such as a baseband/application processor, a DMB chip and other devices, as illustrated in Figure 2 below.

Samsung Semiconductor Package Information

The system-in-package solution enables a reduction in the package footprint to a great extent, allowing mobile handsets to be designed with the smallest form factors. Samsung security packaging solutions are designed for the latest mobile communication devices containing the most advanced features, such as data encryption, along with high-density flash memory that provide sufficient capacity to store several details about the user. Packaging solutions provided by Samsung for security devices are preferred by designers and OEMs worldwide.

Key Features and Benefits of Samsung's Packaging Techniques for Security Solutions Devices

Samsung's packaging solutions for security devices have some of the most distinct features, making them ideal for packaging devices such as NFC controllers that are widely used in mobile handsets and other, similar devices utilizing the NFC protocol stack. Some of the most significant of these features are listed below:

  • Available in multiple combinations :
    Samsung provides packaging options for security solutions devices in the following combinations :
    • NFC + T-DMB + SE : The first combination provides an integrated solution with an NFC controller, a T-DMB (Terrestrial Digital Multimedia Broadcast) controller, and an SE (Security Element), all in the same package. Such a package is usually referred to as a system in package, or SIP.
    • NFC + CMMB + SE : The second combination provides a similar solution which combines an NFC controller and SE element with a CMMB (China Multimedia Mobile Broadcasting) standard content decoder. The CMMB standard applies to mobile television and multimedia signals specified and used in China.
  • Wide ball counts :
    Samsung's packaging techniques for security solutions offer wide ball counts, making it easy to provide high density devices with a large number of I/Os within small form factors. Ball counts are easily configurable, and can be taken to values as high as 600 in a single FBGA package.
  • Reliable thermal performance :
    Security solutions devices packaged using Samsung's advanced packaging techniques demonstrate excellent thermal stability, and offer reliable operation for the device, preventing conditions such as thermal runaways, and are capable of safely handling powers up to 2 W.
  • Available in lead- and halogen-free variants :
    Samsung's packaging techniques for security solutions use the latest, lead- and halogen-free manufacturing processes, making the material for the devices environmentally-friendly, and easier to recycle and reuse.
  • Excellent operational reliability :
    Samsung's security solutions packaging techniques provide significantly high reliability to the packaged device.
    • Moisture sensitivity characterization : JEDEC Level 3 (30°C/60%, 192 hours, IR 260°C, 3 times)
    • Highly Accelerated Stress Test (HAST) : 96 hours (130°C, 85% relative humidity)
    • Boundary temperature cycles: 500 cycles (-65~120°C)
    • High temperature storage: 500 hours at 150°C

Application Areas for Samsung's Packaging Techniques for Security Solutions Devices

Samsung's packaging solutions for security devices have some of the most distinct features, making them ideal for packaging devices such as NFC controllers that are widely used in mobile handsets and other, similar devices utilizing the NFC protocol stack. Some of the most significant of these features are listed below :

  • Accessing information on the move :
    Devices such as mobile handsets with NFC modules packaged using Samsung's advanced packaging technologies can be used to read smart posters and labels and other types of encoded, embedded digital content, making it easy to access information on-the-go.
  • Making mobile payments, and e-ticketing :
    NFC has been implemented in mobile phones primarily to enable mobile handsets to act as payment gateways, e-tickets, and let mobile devices act as "electronic identity cards” (such as a medical ID card). Samsung's high-quality packaging techniques ensure that such transactions are carried out conveniently and safely.
  • To transfer data between devices :
    Samsung's packaging techniques make it easy for two NFC devices to automatically initiate a network communication session without the need for any configuration, making it easy for the user to share content, such as audio, video, and image files.
  • As security devices :
    High quality NFC devices packaged using Samsung's packaging techniques can also be used as "smart keys” to access personal spaces.
  • In marketing (targeted advertising) :
    NFC devices packaged using Samsung's packaging techniques can be used for customer-centric marketing, using the principle of targeted advertising.
