According to the purpose of electronic testing, probes can be divided into:
1. Microelectronic test probe: that is, a wafer or a chip IC probe. For example, tungsten needles are used in probe cards and probes for wafer testing.
2. Optical circuit board test probe: a probe used in circuit board test before components are installed, or a probe for only open circuit and short circuit.
3. Online test probe: a probe used after installing components on the PCB circuit board.
ChinaTungsten Online provides you with pure tungsten probes and other tungsten probes for different probe platforms such as probe cards and probers, with different specifications.
