itself with the solder pad, also chang- ing the position of the placed devices. This auto-correcting property of sol- der reflow makes accurate positioning of SMD components and solder paste before reflow critical for preventing reflow defects. In addition to sharing data with immediate production line neighbors, these SPI systems from TRI can communicate with inspection and production equipment to reduce production costs and collect diagnostic information to analyze root causes of production defects. SPI is a key QC component de -

them on unpopulated boards, such as the model CB8 or CB29 boards, or by customizing a board for test purpos- es. Depending upon their size, har- nesses can be tested by a number of approaches: by building a mating harness, by constructing a panel with all of the required connectors, by building "pigtail" cables, or by mount-mating connectors on a CB8 custom interface board for testing. The custom PinMap™ software allows all connectors and pins tested on the CableEye system to be custom labeled. The use of a flexible cable and
harness test system such as Cable - Eye can save time and boost produc- tivity. It is a relatively easy-to-use system that allows operators to be running in about 10 minutes after connecting the hardware and in - stalling the software on a PC. The "plug-and-play" system uses USB connections for speed and simplicity, with reliable low-voltage tests per- formed by base units quickly and effi- ciently.
Mapping Connectors Before proceeding to test, con-
nectors not in the connector library must be mapped to CableEye’s tester headers, a one-time process. The use of the optional PinMap software sim- plifies mapping the pins of complex and custom connectors and test fix- tures. Operators are prompted by audible tones to help speed and sim- plify testing. For assembling complex or mis-
sion-critical connectors, the Light- Director™ accessory to CableEye can help boost productivity, eliminating assembly errors from manual produc- tion. CableEye allows the same equipment used for assembly to be used for testing, to minimize time wasted in moving products to be test- ed around the production floor. CableEye’s dynamic GUI contributes to faster and more accurate design, assembly, test, and diagnosis, result- ing in improved productivity. Contact: CAMI Research, Inc.,

signed to minimize production losses by identifying solder paste printing defects during early stages of produc- tion. In addition to defect detection, SPI can be integrated with a printer and other equipment in the produc- tion line to optimize quality, auto- mate cleaning functions, and identify
defective boards in placers, buffers, and other in-line production equip- ment. The closed-loop SPI system solution from TRI delivers the advantages of SPI to help minimize line stops, reduce material costs, and minimize needs for operator inter- ventions.
This one-stop SPI system solu-
tion from TRI is part of a robust product portfolio in support of auto- mated electronic manufacturing test and inspection. The firm supplies SPI systems as well as automated optical
inspection (AOI), three-
dimensional (3D) automated x-ray inspection (AXI) systems, manufac- turing defect analyzers (MDAs), and in-circuit test equipment, as cost- effective solutions meant to meet a comprehensive range of manufactur- ing test and inspection requirements. Contact: Test Research, Inc., 7F,
