Chips should be standardized and easily replaceable. Have a replacement schedule during regular maintenance. Problem solved.
You could go with a socket-less design, but then you need expensive equipment and a highly skilled technician to do the replacement. You still lose the conformal coating, as such coated boards are not very repairable in the general case.
For as much as you'd pay for a replacement chip and labor, a new PCB costs ten times less.
Component level repair is never an economical option in this scenario. It only works out if replacement parts are unavailable.
Do you want your ABS controller to be seated like that? Seems like a genuinely terrible idea.
That is actually the hard part, odds are the chips inside are not longer made. When making ABS controllers the OEM guesses how many replacements will be needed and buys that many extra to put in a environment controlled warehouse - when they guess wrong they run out and if the parts inside are no longer made the rest of us are out of luck. If the chips inside are still made the OEM will generally order more (if they run out before the expected date that implies there is a lot of demand so it is worth ordering more).
The expected date above is for normal care lifespan. If you are a collector good luck.
You obviously can't expect them to support models forever. Even right now their suppliers keep open ancient manufacturing lines for the ancient chips used in these controllers.
>If you are a collector good luck.
Good thing that is a small minority of, usually well off, people.
How big do you want your automotive-grade chips to be?
And we should trust you because...? I wouldn't trust you because of the way you insult professional technicians that work on your car, and obviously know little about the profession.
That, and if you think replacing these parts would involve soldering and not a complete module replacement, I wouldn't trust your opinion on anything electronics-related, either.
They existed because the manufacturers would not always release the factory schematics or service manuals for mass-produced consumer products.
This proliferated once consumerism & disposable-ism really took off, before that most electronics came with a schematic, but it was still not often up to the standards of places like HP or Tektronix.
So Sams took what info they could get and reverse-engineered the rest as they tore down and scrutinized new equipment to produce these fairly standardized publications that were available by subscription to independent repair operators, covering each popular model from many different manufacturers as they emerged in the marketplace.
A lot of the repair operators were very familiar with gear like HP and Tek and so was Sams.
Most of them had successfully leveraged that kind of top documentation and serviceability to have materially contributed to the winning of World War II. Slouches they were not.
There was a preference not to want to settle for less in consumer electronics so they published their own to make up the difference. If the skills are there why not use them? Especially when a failure is usually only one or a small number of the most common dirt-cheap components that need to be replaced to fix.
Which is what electronics servicing is supposed to be all about from the beginning.
I know it's not the beginning any more but still there was a time when the pros had in the back of their mind the kind of things it might take to win World War III, more so than now.
With people like that around you didn't need right-to-repair laws to be enacted, the whole country was still aware of the benefit of field repair if not improvisation.
All of the overseas Communists were certainly not going to sleep on it.
