ICT Testing—TECOO
The PCBA production process is complex. Depending on the complexity of your project -- or how much risk there is if something fails -- you may need to do high-end testing before releasing a product.
ICT is an automatic online tester and a test equipment for PCBA (Printed-Circuit Board Assembly) production that is necessary for modern electronics companies. ICT has a wide range of applications, high measurement accuracy, and clear instructions for detected problems. It is very easy for even workers with average electronic skills to deal with problematic PCBAs and is a very reliable PCBA test method.
As a expert electronic manufacturing service (EMS)provider, TECOO has a professional manufacturing team and a unique set of testing methods in PCBA, which can greatly shorten the delivery cycle on the premise of ensuring product quality.
Advantages of ICT Testing
◆ Each PCBA is quickly tested, and the test time of a single board is generally several seconds to tens of seconds
◆ Excellent retestability, controlled by computer program, greatly reduces the risk of misjudgment and missed test, and reduces the trouble of the production line
◆ Online inspection of components and short circuits and open circuits of each circuit network
◆ Defects in the manufacturing process and defective components can be found by directly testing the electrical performance of online devices (measure components such as resistors and capacitors, and perform functional tests on diodes, transformers, relays, etc.)
◆ Can be set to turn on and test LED components - e.g. by enabling color and brightness verification
◆ ICT can tell which part has a problem through a computer program, and the tested fault is directly located on the specific component, device pin, and network point. The fault location is accurate, and maintenance is convenient, which can greatly improve production efficiency and reduce maintenance costs.
◆ Improve product quality, as long as there are enough test points, ICT can measure all circuits and parts on the circuit board, which can improve product quality
Disadvantages of ICT testing
◆ High upfront costs, ICT equipment and fixtures are generally more expensive, especially pneumatic steel fixtures, which are more suitable for mass-produced products
◆ Programming and customization tools are required, and additional test points need to be designed on the circuit board for bed-of-pin connections during ICT testing
◆ Regular maintenance of needle beds and probes is required to ensure the normal operation of subsequent work
◆ Test points sometimes have different contact problems due to different surface treatments
Custom manufacturing
ICT testing is the most cost-effective way to meet both low and high volume product needs. Its 99% accuracy combined with skilled and experienced electronics contract manufacturers (TECOO) is virtually fail-proof.
