In the vast electronical test industries, the application of test probes is very extensive, and people usually classify test probes according to their applications.
There are many test occasions in the electronics industry, such as Wafer Testing, Packaging Testing, PCB bare board testing, In-Circuit Test, and Functional Testing (FCT) of load boards, as well as Batteries Test.
According to the differentiation of functional tests, engineers divided tests into Open/Short Tests, High Current Tests, High-Frequency Tests, Switch Tests, etc.
Nearly most of the semiconductors are applied on BGA, LGA, and QFN products test, those are very fine pitch probes, even covered with high frequency and high temperature.
They are compromised with double-ended probes and single-ended probes, some work for burning tests, and some work for functional tests. JYPROBE provides from pitch 0.3mm to 1.00mm probes solution.
Namely, we called ICT and FCT probes test probes in short, starting from 39mil to 187mil test pitches, those test probes are used to check loaded PCBs and Server Boards.
This type of test probe can test terminals of wire harnesses or cable blocks and can cover from 50mil to 150mil test pitches. We should consider high current by using threaded/ screw-in probes.
The interface pins are generally special-custom pins according to test fixtures or testers (Teradyne and Keysight).
High-current probes are often designed to test some power and high-current modules, they specify from 10-100Amps even higher.
Many charging products all over the world have used battery probes for current charging. They are covered by injection modules. A few of high-quality battery probes will be applied to photographic equipment or magnetic connectors.
RF spring contact probes are made to test a variety of RF signal boards or components, from DC to 10GHz, from Fakra to Board-to-board connectors, applied on wifi modules, Bluetooth modules, antennas, etc.
