IC testers, do they work?
(1/9) > >>
RiRaRi:
Hello. I have seen these testers for integrated circuits. Do they work and does anyone have experience with them? How simple are they to use?

What concerns me is no list of ICs programmed into the tester is given. I would not expect it to test just any IC, probably just a logic series. At least with the XGecu EPROM programmer series which also has a testing function, the list of ICs tested is listed.

I've actually been meaning to post a thread on these myself for the past few days.

I've had one of those for years and it's 50/50, so I've been wondering if they've improved in terms of recognised parts? Or if people make new parts libraries you can update them with, etc.

Mine is pretty good at testing logic chips, so that's something. Very limited with op amps etc though, which is what I'm usually wanting to test when I whip it out.

When it does recognise a particular type it can be really handy. My normal use for it is while working on mixing consoles, I'll often be trying to quickly troubleshoot multiple channels and it can be super quick for pulling and checking a bunch of suspect parts all in one go. It's always a crapshoot though whether or not it will recognise the particular op amp in use, a lot of super common parts just show up on mine as unknown/damaged parts

If you watch the lame little video on AliExpress, near the end, you can see them scrolling though 74HC, 74LS, & CD40... So I would guess that it's pretty limited.
According to the poorly translated description:

--- Quote ---You can test 74ch series, 74ls series, CD4000 series, HEF400 series, 4500 series, operational amplifiers, interface class chip, optocouplers, transistors automatic identification, the regulator voltage value recognition.
Built-in data model all kinds of chips more than 1,300 species, more than 420 kinds of transistor data models, covering most common devices within 24 feet, and can greatly reduce the maintenance workload, improve maintenance efficiency.
The repair wizard 9v laminated battery, the same as with ordinary multimeter battery, power consumption is quite ordinary digital multimeter. Press the enter key can boot first boot automatically perform a self-test, self-test the battery voltage is detected and displayed on the screen after the passage of more than two seconds, when the battery voltage is below 7v replace the battery, in order to ensure measurement accuracy. If there is no alarm you can start measuring work. Native AD 10 AD, the theoretical resolution of 5v voltage is 0.0048v. Not suitable for measuring high power thyristor due to the use of battery-powered. Zener value should be subject to the measured, can not only look at the nominal value. Boot the default directory is search directory. An ordinary optocoupler optocoupler test up to a dozen parameters, a simple measurement optocoupler logic relationship has not much practical significance, the machine can test the secondary optocoupler saturation voltage, for reference. Test the ordinary 4 feet optocoupler.

This YouTube guy reviewed one which looks the same as that one. Haven't watched the entire thing. At the 10:50 mark he shows the IC list that came with it.
Someone:
Probably more correctly described as a IC identifier rather than a tester, there are no pass/fail criteria or performance measurement as would be associated with testing.
