Could you imagine the outrage if, say, Ford required NDAs to be signed by independent repair facilities (or even backyard mechanics) just to be able to purchase the instructions, gaskets, and the

How would you replace a bad FPGA? (Assume BGA, please, and internal data storage).? How would you replace a bad mask programmed microprocessor (or even one that isn't)? Programming hardware (to

Dear Jaret hi.Thank you for your reply. I had a suspicion that it my be the button in the panel. I will order a set and I hope that it will resolve the problem because I can't find any problem in the

I agree 100%.

I think some of you are missing the point.? You're telling me (as if to be reassurred this is how its supposed to be) that because the manufacturers themselves are no longer doing component level

I hear R&S makes some nice gear, I don't have any.? Pretty much unrepairable. I was given a very nice R&S transceiver that pretty much worked but has some problems.? Unrepairable, even with module

I don't agree that programming a custom chip is difficult.? Chip programmers are cheap and plentiful on the market and common with hobbyists. What may be uneconomical for a manufacturer might be

That's very noble of you, Ozan. And if it's of any reassurance, leaving everything I own to animal charities has been my plan all along and I made a Will out to that effect many years ago. Now a

Dear All, One of the issues has been change of customer requirements. Back in the HP Days, the US and other military customers did component level equipment repair; they therefore required complete

While the commercial reasons for poor repair documentation are easy to appreciate, this is an example of where the most profitable route is not best for society as a whole. There are many such

Nik, what you describe is broadly speaking correct for Keysight too. They too have people who estimate the need for new and rebuilt assemblies for the period after product obsolescence. If an

Im not sure thats quite the whole story Vladan, or at least it wasnt for me in the early 2000's when i worked for Applecare Engineering. You dont simply create all the spare assemblies you think you

When the supply chain fails as happened with Covid, it could even become a national security issue when companies are unable rather than unwilling to make timely repairs…and where new equipment

Frank, I will tell you something interesting. At Keysight, they still have a few people who repair broken in house equipment (e.g. for the R&D lab). However, if they have to dig deeper than described

Yes, times have changed and that is what the OP lamented. Until around 1990, it was still economical to have an in-house repair department that could find a bad IC or transistor. Almost everyone

Chuck, Fair enough.? I get your point.? I think you could have used a better example though.? I understand the difficulties in passing legislation.? I already stated that I don't think

Vladan, I really appreciate your input as you do have the advantage of all 3 vantage points.? I am not a designer.? I am a consumer and a professional repair engineer.? And I think you take my

Why am I here? Possibly to teach guys like you that modern equipment isn't always economical for guys like you and me to repair. Companies providing schematics wouldn't change that fact one

Sadly, I didn't think you would understand... I inferred your desire to share in proprietary manufacturing processes from what you were asking. Programming a custom chip is a part of the

I am a hobbyist and also a professional in engineering who has for decades made purchasing decisions.? In my career I have leaned toward buying equipment that is supportable.? Yes now that is
