ICT test needle maintenance

ICT test probe plays a very important role in the ICT test process. Although the probe is a consumable material, if it is well maintained, the life growth of the probe has a certain effect on the cost control. How to maintain the test probe and make it last longer, here are the five key points of probe maintenance:

Application of test probe in electronic testing

The types of test probes include PCB probe, ICT functional test probe (automotive harness test probe, battery probe, current and voltage probe, switch probe, capacitor polarity probe, high frequency probe), BGA test probe, etc. According to the different origin, it can be divided into QA probe, ECT probe, IDI probe, INGUN probe, PTR probe, LEENON probe, CCP China probe and Taiwan UC Youchuan probe.

The composition structure of ICT probe

The commonly used ICT test probe is composed of needle, outer tube and spring. Because the ICT probe pays great attention to its conductivity, durability and hardness, electroplating is a very important part in the manufacturing process. Before assembly, the parts are specially electroplated so that a probe with acceptable electrical parameters can be assembled.

How does the probe work?

The probe is a small piece of single-stranded DNA or RNA (about 20 to 500bp) that is used to detect the complementary nucleic acid sequence. The double-stranded DNA is heated to become a single strand, which is then labeled as a probe with a radioisotope (usually phospho-32), a fluorescent dye, or an enzyme (such as horseradish peroxidase). Phosphorus-32 is usually incorporated into a phosphoric acid group, one of the four nucleotides that make up DNA, while fluorescent dyes and enzymes are covalently bound to nucleic acid sequences.
