Everything PCB !

There are several different types of ICT machines in the electronics manufacturing industries. The machine type usually is dependent on;

-The manufacturing or testing process

-The volume of purchased PCBs and

-Types of PCB

-The main types of ICT machines include

Standard ICT machine

In normal circumstances, this is the general test in this form of testing. However, they’re standard because they offer elemental resistance, capacitance, and some device functionality.

Manufacturing defect analyzer, MDA

MDA offers an essential ICT of resistance, continuity, and insulation. Manufacturers use it to detect defects such as shorts and open circuit connections on the board. It uses the printed circuit board CAD data to generate the fixture design and test programs while operating. Thus, you can automatically produce about 80% of the programs.

Cableform tester

As the name suggests, you use its operation to test cables optimally. It works similarly to an MDA but differs in high voltage usage. The high voltage is for periodic testing for the insulation.

Flying probe tester

A roving or flying probe has a simple, inexpensive fixture that holds the board. A testing team then connects via a few inquiries that move around the board and make contact as needed. Often, software control monitors the movements of the probes. Therefore, any board updates will lead to a change in the software program. 

When choosing a type of ICT machine for your products, consider the following elements common in all ICT testers. They include; controller, software, interface, fixture, analog scanner, powered analog tests, and analog-digital opens. At all times, the mentioned elements steer the operation of ICT.

What are the advantages of ICT?

ICT has some significant advantages that have been the reason manufacturers opt for it for centuries.

They include:

-In contrast to the AOI and flying probe testers, it can test the ball grid array assemblies (BGAs).

Straightforward interpretation: the ICT system quickly locates the faultiness and presents it to you in a matter of minutes. You may not need professionally skilled personnel to proceed with the interpretation.

Fast/ Time-effective: it roughly takes 1 minute in comparison to a flying probe tester that may take about 25 minutes. Being short is in regards to contacting all the board’s test points at once.

Easy program generation: an ICT tester is effortlessly programmed. In that, you can take files from the PCB outline to make the essential program.

-It can test functionality as well as assembly defects as ICT systems can handle complex testing methods.

Cost-effective: The high speed helps in quick recovering of the expense of setting up the fixture and program. It is especially true when considering boards that you assemble in large volumes.

ICT platforms: The testing platform for ICT is available in both Windows and UNIX OS, making it universal.
