PROBING AND ANALYSIS ADAPTERS
 |
|
We offer probing adaptors and logic analyzer adaptors for all SMT package types, as well as socket probes for DIP and PLCC. We are Agilent and Tektronix partners. In addition, we offer adapters to facilitate the use of in-circuit emulators and FPGA development systems. | |
General Information and Definitions
In-circuit testing of surface mount packages such as BGA, PLCC, QFP, and SOIC presents the challenge of reliably gaining access to signals for probing. Testing may require use of a high speed logic analyzer. To meet these challenges, Ironwood creates the most reliable, versatile probing systems for the Design and Development engineer.
- Probe Boards
- "Probe boards" refer to components that provide test points, which are usually pins suitable for use with test clips and flying leads.
- Carrier Adapters
- We use the term "Carrier Adaptor" to designate a modular system that plugs into an SMT emulation base , or foot, that is soldered in place of the IC being tested. Various probe board modules and socket combinations can then be plugged into the base as needed.
- Logic Analyzer Adapters
- Ironwood's "Logic Analyzer Adaptors" are probing adaptor products that are designed for use with specific logic analyzer equipment. High speed analyzers such as one of the Tektronix TLA700 or Agilent 16000 series require vendor-specific interfaces and clean, controlled impedance signals.
- FPGA Development Adapters
- Ironwood's FPGA development adapters mount in place on target boards and provide test points as well as a programming interface. Currently, we support the Xilinx Xchecker configuration system.
Probing and Analysis Adapters
Ironwood's line of probing, testing, and logic analyzer adaptors consists of the following products:
- BGA Probing Systems (Carrier Adapters)
Ironwood leads the industry in BGA probing systems. We have developed probing adapters for 0.75mm pitch BGA packages. Some of our BGA probing adaptors incorporate our own high performance GHz BGA sockets.
Most of our BGA probing systems are modular and are called "carrier adapters". Typically, a carrier adaptor system uses a BGA emulator base adaptor, a probe board, and a choice of socket interfaces ranging from an SMT "land socket" to an industry standard ZIF socket.
- Socket Probes for DIP and PLCC
Our socket probe adapters provide connections for test equipment to in-circuit DIP and socketed PLCC packages. The DIP socket probes are available with 3-level wire wrap pins.
- PLCC Probing Adapters
PLCC systems may be probed by using a surface mounted carrier adaptor system or one of Ironwood's two clip-on probe adaptor systems. We also offer PLCC socket probes that provide access to in-socket signals.
- QFP Probing Adapters
Our QFP carrier adaptors consist of an SMT emulation base and a probe board that plugs into the base. Options for specifying ZIF sockets, production sockets, or surface mount lands are generally available for probe boards. All of our QFP probe boards may be specified to provide test lands, rather than test pins.
- SOIC Probing Adapters
Our SOIC probing adaptors include an SMT emulation base and a probe board that plugs into the base. Open top ZIF sockets or surface mount land options provide connections to the device. Our SOIC probe boards may be specified to provide test lands, rather than test pins.
- Logic Analyzer Adapters
We offer a number of adapters that support high speed probing using Agilent 16xxx or Tektronix TLA 7xx logic analyzers. These adapters incorporate vendor-specific interfaces and clean, controlled impedance signals. Ironwood has qualified as both Agilent and Tektronix qualified partners.
- FPGA Development Adapters
These adapters allow FPGA development and programming. We offer adapters for the Xilinx Xchecker configration interface that can be used in place on target system boards and also provide test points for each signal.
