Everything that you should know about the In-Circuit Testing

 

The printed circuit are the ones that come with the complex assembly of numerous components and solder connections. Every component has to rightly function. Even the slightest glitch can make the device non-functional. Hence, testing each of such components is almost nearly impossible. But again, testing is the most important part of the process. Here is how the in-circuit testing comes to play. So, let us move ahead with the discussion of one of the most cost-effective testing process-

What are the common defects that can be found in in-circuit testing?

The common types of glitches that can be diagnosed in the in-circuit tests are- component marking, lead spacing, land sizes, component spacing, soldering, values of resistors, a mistake in the capacitance values, open circuits where there is a requirement of the flow of electricity, etc.

What are the elements of the in-circuit tester?

Various types of in-circuit tester available in the market have different components and procedures of testing. And employing the right tester is an important step for a manufacturing company to understand the glitches in a PCB and bring out glitch-free products to the market. But irrespective of the type of tester you choose, the following components can be easily found in the in-circuit testers- controller, software, fixture, interface, powered analog tests, analog scanner, etc.

Pros of in-circuit testing:

Some of the major advantages of using superlative quality in-circuit testing like Ingun testprobes are-

The in-circuit test probes are the easiest program that can be used to detect defects in the components.

•    Quite fewer chances of operator errors are there
•    Not a time taking the program to be conducted
•    It is a reliable testing program and can cover manufacturing defects
•   The results of the test are easy for interpretation
•   No maintenance cost

Cons of in-circuit testing:

All the technologies will always have some drawbacks and the in-circuit testing is no different. Check out the pointers below to know all about the disadvantages of the PCB assembly.

•           The test fixtures of in-circuit test probes can appear to be costly
•           The in-circuit testing might fail to diagnose defaults like high density
•           Inconsistent results can also be achieved in case if the test pins are not connected properly with the test pads.

Final Words:

The PCB testing helps in checking well with the quality of each component in an in-circuit board. Not only the user can complete the testing of every component in time but the type of performance of every component can also be noted. This is a solution that has been used by the market for years. It helps in dealing with the dynamic testing of the product. All the companies offering PCB or prototypes to the market require this tool for effective testing of the components in a very less time.
