Why is 'Solid capacitors on CPU VRM' a selling feature on Motherboards?
Why is it a good thing (or not) when motherboard spec sheets state "Solid capacitors on CPU VRM"? I understand that VRM refers to a (step-down) voltage regulator but what's so good about using "solid capacitors"? Is the alternative surface-mount versions? What are the (dis-)advantages of each? Thanks.
Solid and ceramic capacitors don't leak like standard ones.
Another selling point is them being made in Japan. This is not bogus because japanese accumulators, batteries and capacitors are the highest quality in the world
(due to them spending effectively trillions of yens for decades on researching how to make them more effective) and easily hold more charge than cheap chinese knockoffs etc., they have lower failure percentages and so on)
Note that motherboards with solid caps or ones made in Japan will cost $50-$100 more than normal motherboards.

UIM24002/UIM24004/UIM24008 Stepper Motor Controller with Microstepping
Features:
Miniature Size 42.3mm*42.3mm*13.5mm
Integrally designed to fit onto motors seamlessly, as well as work standalone
10-40VDC supply, Max 2A/4A/8A adjustable output current, 1to16 Microstepping
Dual H-bridge with PWM constant current control,
Enable/shutdown controllable
Opto-isolated inputs with common anode.
Die-cast aluminium enclosure
Overview
UIM24002/24004/24008 is a series of miniature, high performance stepper motor controller. They can be mounted onto 42/57/86/110 series stepper motor seamless through corresponding flanges. The thickness of these controllers is less than 14mm, UIM 24002 is capable to provide 0.5-2A adjustable current. UIM 24004 is capable for 1.6-4A adjustable current output. UIM24008 is capable for 2A-8A.adjustable current output. Their mixed-decay current control reduces the back-EMF effect under high speed running condition and improves the performance. Except the UIM24002 takes 10-35VDC input, UIM240xx series controllers can work with 12 to 40VDC input.. Enclosures of the UIM240xx controller are made of die-cast aluminum which provide a rugged and durable protection and improve the heat dissipation..
