IC testers to see if vintage chip is good or bad

Semiconductor test equipment (IC tester), or automated test equipment (ATE), is a system for giving electrical signals to a semiconductor device to compare output signals against expected values for the purpose of testing if the device works as specified in its design specifications.

IC Testers are devices which are used to test Integrated Circuits by sending in Pulses as per their Truth Table. Generally, IC number is fed into IC Tester and a comparison test is made against that particular IC’s Logic Table.

If you have many old logic ICs that you are not sure if they work (either on your misc ICs from old equipment bin or inside old device that does not work), IC testers can be useful tool. Keeping old computers and other electronics running can sometimes be a difficult task due to the fact old chips fail. Having something that can quickly test the myriad of chips if they are OK or NOT, can be really helpful in keeping these machines alive.

IC Testers used to costly special instrumentation devices that are certainly not a mandatory addition for your collection of test and measurement-equipment. But nowadays there are also cheap alternatives at electronics experimenter price range (starting from tens of euros/dollars).

Keeping old computers running can sometimes be a difficult task due to the fact old chips fail. Having something that can quickly test the myriad of chips on in these old computers would be really helpful in keeping these machines alive. Many IC tester device promises to do just that, watch to find out if it delivers.

I some time ago thought I might needs one IC tester, but finally decided that at the moment I don’t need it so much that I would buy one now. So I have just read the product pages and reviews to write this article, and I have not personally tested any of those products.

Here is the overview of IC testers currently on the market I have found:

Unbranded IC-Tester from eBay

The multi-function integrated circuit tester is a professional instrument designed for the first-line microelectronic engineering staff , maintenance staff . Different test mode can be selected 5v mode , 3.3v mode , AUTO mode can test 74HC series 74LS series , CD4000 series , HEF400 Series , 4500 Series , operational amplifiers, interface class chip , optocoupler transistor automatic identification regulator regulator value recognition , and so on . Built-in 13 kinds of various types of chip data model , the transistor data model more than 420 kinds , covering a majority of 24 feet or less common universal device , can significantly reduce the workload and improve work efficiency

BackBit Chip Tester Pro

BackBit Chip Tester Pro is a tool designed to help vintage computer diagnosis and repair. Tired of playing a guessing game with swapping chips? Don’t want to risk putting bad chips in a good machine (and vice versa)? Want to do as little desoldering as possible? Then the BackBit Chip Tester claimed to be your solution.

It definitely has a unique twist to it that makes it stand out for vintage computer repair applications. It’s particularly aimed at Commodore enthusiasts, but it goes much beyond that.

Is This The Retro Chip Tester For You?

Retro Chip Tester Professional

Retro Chip Tester Professional 1.2h by Stephan Slabihoud/8Bit-Museum.de

This has claimed to be the ultimate DIY retro chip tester aimed in helping to keep keeping old computers. Having something that can quickly test the myriad of chips on in these old computers would be really helpful. This device promises to do just that, watch the following to find out if it delivers.

The Retro Chip Tester Pro does it all

This video shows the initial impressions of a quite low-priced IC Tester that I bought on eBay. The tester is supposed to identify and evaluate logic ICs in the 7400 series, 4000 series, 4500/14500 series, plus Op-Amps, bipolar and MOS transistors, Zener diodes, opto-couplers, small SCRs, and a few other parts.

    In the RCT section you wrote “The biggest problem was hat documentation was poor. ”
    The RCT has the best documentation of all projects I have ever seen. Check yourself. You can download teh manual from their homepage, it is 200 pages big and 60 more pages about the BOM etc.

    Why are curve tracers still so expensive? I respect the big old Tek instruments, but with a µP and small monochrome touchscreen it should be simple to get most of the same functionality without much hardware. A small Variac, tapped power transformer, simple V/I converter for base drive, a few rotary switches and resistors…

    Heathkit, Leader & Sencore boxes are expensive (if you can find one) for what they are, limited V & I ranges and need XY oscilloscope for display.
    I see https://www.instructables.com/Transistor-Curve-Tracer/ Is something like that (ideally with more power) available commercially?

    I hope this site called https://programminginsider.com/best-sites-to-get-programming-assignment-help/ does not become a shambles. Because I believe I am infatuated with the level of service they deliver. There are no drawbacks!
