Diverse Applications: Exploring Seven Types of PCB Probes for Electronic Testing and Connectivity
PCB probe is an electrical test of the contact seek intermediary, belongs to the important electronic components,wafer tester electronic components connected to the conductive carrier. pcb probe is widely used to test the pcba a kind of data transmission, conductive contact, through the probe conductive transmission of the functional body of the data to determine whether the product is normal contact as well as normal operation of the data.
Usually the circuit board probe has many specifications, mainly composed of three parts: First, the needle tube, mainly copper alloy as the material outside the gold-plated. Second, the spring, mainly piano steel wire and spring steel outside the gold-plated. The third is the needle, mainly tool steel (SK) nickel-plated or gold-plated. The above three parts are assembled into a probe. In addition, there is a jacket tube, can be connected to the welding line.
Types of PCB probes
1.ICT probe
Generally used in 1.27mm, 1.91MM, 2.54mm pitch, commonly used series: 100 series, 75 series, 50 series,wafer probe testing mainly used for on-line circuit testing and functional testing, ICT testing and FCT testing in the measurement of the PCB empty board used more.
2.Double probe
Used for BGA testing, more compact, workmanship requirements are higher, the general detection of cell phone IC chip,vibration isolation table laptop IC chip, tablet PCs and communication IC chip, etc., the diameter of the needle lies between 0.25MM ~ 0.58MM.
3.Switch Probe
Switching probe alone a probe has two current, control circuit of normally open and closed function.
4.High frequency probe
Used for testing high-frequency signals, with a shielding ring can be tested within 10GHz and 500MHz without a shielding ring.
5.Rotating probe
Elasticity is generally not high, because of its penetration would have been very strong, generally used for OSP processed PCBA test.
6,.high current probe
Probe diameter between 2.98mm-5.0mm, the maximum test current up to 50A.
7.Battery contact probe
Generally used to optimize the contact effect, good stability and long life, cell phone battery contact parts of the conductive use, SIM data card slot and the general use of the charger interface conductive use more.
