Beyond the Boundary Scan Test: Testing for Mid-State/Resistive Shorts

Beyond the Boundary Scan Test: Testing for Mid-State/Resistive Shorts

Mid-state shorts are a major problem that often goes undetected by typical boundary scan connectivity tests is mid-state/resitive shorts. Flynn Systems recognized this “hole” in boundary scan testing and was the first boundary scan test company to test for mid-state shorts, improving test fault coverage.

How Boundary Scan Test Software Works

How Boundary Scan Test Software Works

The boundary scan test software provides a way to interconnect between integrated circuits (ICs) on a board without using physical test probes. The scan contains cells within a device that can capture data from pin or core logic signals or force data onto pins. The...

Testing Multichip Modules

Chip manufacturers are now producing multichip modules (MCMs) that may include two or more arrays of devices within a single package. These modules can be tested using JTAG test pattern generation of the devices while on a PCB. To incorporate JTAG testing of MCMs...

How Board Developers Can Save Their Company Time and Money

Not every boundary scan application experiences delays. Some run without any problems, but when there is a delay, oftentimes it can be traced back to lack of information from the board’s developer to the board’s tester.

A Look at Boundary Scan Description Language (BSDL)

Introduction As miniaturization of PCBs became more desirable, denser (or layered) printed circuit boards began to dominate the market. Testing electrical connectivity between devices posed a huge problem because  board density and complex layering prevented the IC...

Flynn Systems Announces upgraded Boundary Scan Tools: onTAP Series 4000

The goal is to exploit JTAG testing to achieve maximum fault coverage in addition to Flash programming and configuration tasks,” says Hank Flynn, CEO of Flynn Systems Corp. Like so many new features added to onTAP, Flynn’s introduction of the upgraded ATPG was a direct result of meeting customer needs. “Even if a tool has the capability to provide high fault coverage, when too much user intervention is required, chances are fault coverage goals will never be achieved. It’s clear that increased automation throughout the test prep experience is the key.” Says Flynn.
