Test of Microlectronics

Microelectronic testing has for many years been synonymous with test solutions using high cost, automatic test systems (ATE), often referred to as “Big-Iron” test systems. However, changes in design technology, chip architecture, and instrumentation as well as emerging standards and practices facilitate new, highly efficient, and more cost-optimal alternatives.

Along with growing chip complexity, a wide spread use of built in self-test, BIST, and scan based designs, e.g. various flavors of IEEE std.1149.x Boundary Scan, as well as IEEE std 1500 - Standard for Embedded Core Test, IEEE std 1532 for In-System Programmability (ISP), etc. have emerged in recent years. Such architectural improvements, along with other design improvements, typically simplify the need for external test equipment. Paralleling such developments, the significant growth in modular instrumentation – even up to the level of sophisticated RF instruments - has made it possible to devise and architect highly flexible test solutions at very competitive costs.   

Supported by a professional market for high level software, including test sequencer, high level instruments, data mining software, etc. – combined with the above mentioned new hardware options -  the market for automatic test equipment is in a flux of change. It means that a large part of the system software for automatic test systems can be obtained in the open market as well as the necessary hardware. A user is then no longer forced into an almost monopoly type of relationship with a test system supplier, once he or she has chosen a given test system solution. Instead, the modularity in the system solutions caters adaptation to present needs - still offering the flexibility to expand a system solution as needs changes. The price advantage is superior – not least from a total-cost-of-ownership point of view.

Chamaj Consult has years of experience in using ATE – not least “Big Iron” test systems, as well as the modern type of modular instrumentation. Combined with its experience in tailoring and building test system solutions to focused needs, Chamaj Consult can assist in bringing the right balance into the future test solutions for microelectronics testing in your company.
