Hi, Lsdmeasap
Please provide those links. And you missed the dig I said red but used blue text colour (kinder guessed it was blue after a blue compressor, blue cables, blue tubing, blue collars etc. etc.) ;D
Are we going to see a blue Lsdmeasap "Doctor Den Torture Rack" type signature test jig any time soon lol ;)
The phase change image I saw you were using a black digital thermometer (two red type digital meters monitoring V core and VTT) and probably almost impossible to get a good evaporator box contact if have a sensor on the CPU heatsink. Have you ever seen any cracking or heat-sink warping on the CPU case or dye with those extreme zub zero contact temps.
I still have my first Fluke digital meter (and was still working when last I checked) from the eighties when changed from analogue (the uptake to DVM's was slow due to the old dog sindrome spelled with the i because it was a sin not to embrace DVM's made my life a lot easier). ::)
Back then we actually repaired PCB's measured the components and replaced the faulty transistors and so on (IC's weren't main stream then. DVMs allowed you to measure the transistors junction voltage) you could quickly identify poor to good devices & made it a lot easier to identify silicon or germanium devices ah memories) instead of the junction resistance. In the nineties we even had to replace 100 pin SMD processors (didn't have the luxury of a 500 thousand dollar component De-solder machine only the manufacturing factories had them. We had to cut the old one away and if the component is glued to PCB component pad before solder bath used acetone to dislodge after cutting the pins or any tracks under the IC would be pulled off the IC. Then would line up the new 100 pin IC solder a couple of the corner pins on 4 sides then heat and flow solder over them all and use solder wick to draw the excess solder from between the pins use chloroform to clean flux and looked like never been changed. The pin spacings became so small requiring a microscope final inspections for shorts.
Now it is throw out the old one in with the new. >:( Look at mobo prices complete new Intel board low end around the $100 mid $200-250 top $400 plus cheap.
I always wonder how they can get the quality and be manufactured for such a low low price. Makes you think that the movie "The Terminator" (industrial manufacturing robots now 90% produce all the boards & other products today) due to fuzzy-logic may come into fruition in maybe just a few generations? Then human-beings (due to resource consumption) may become an endangered species.
Technology has over the last 10 years has gone into light speed.
From the 1900s technology was good for 30 years before an upgrade then the moon landings Apollo 11 had 3 navigational computers and they were the humble Commodore 64's. Then the turning point in 1995 Bill Gates Microsofts (no one seems to remember Paul Allen) Windows 95 OS look how far we have gone in just over 15 years due to consumer driven technology uptake (there is even more technology we could have had today that is either sitting on the back burners or the wrights purchased and then shelved due to companies needinging to maintain dominance monopolies & OEMs needing to sell the last of the out-dated technology that they have invested large sums of money in)
Back 2001 Akai had a Plasma 40 inch (January 2001 DTV transmission started in this country consumer could not purchase a DTV TV Akai imported only 8 into Australia available in Feb March) price $29,990.00 (They sold zero in 2001 they predicted that the price would drop to $8,000 in six years LCD wasn't even a mention then) and only 12 months warranty fast forward to today 46 inch 1080p LED edge-lit LCD minimum 3 year warranties for around the $500 CCFL 46 inch 1080p $350 mark even 50 inch plus LCD and Plasma 3D sets $700 to 900 mark.
OEM's had to reduce 3D prices due too the very poor consumer uptake. Consensus reports consumers hate the fact they have to wear glasses OK in movie theartres but not in the lounge room The OEM's do not even keep or have enough parts for warranty repairs they just replace with the new in word "refurbished as new" unit. >:(
Have you managed the get your hands on a Ivy Bridge yet for O clock comparisons especially on the cooling side. I would be greatly interested as from what have read so far they are not going to overclock as easily as the Sandy Bridge (reports of 100c temps) if so than phase change , liquid nitrogen coolers will start to see cheaper prices.
From my early years in the trade as circuits and components became smaller the better you can dissipate that heat the longevity of a unit and components increases. Back in the eighties SMPS designs ever only needed ordinary 75 degree electrolytic capacitors they had plenty of air flow around them and hardly ever saw any swelling or dielectric leaks. The advent of SMD technology feel the OEM (money makes the world go round) did not take that heat factor into account and not enough product testing was evident in high failure rates after only a few years especially SMD electrolytic capacitors their dielectric liquid would leak over the PCB and as very corrosive and circuit would still operate until the combination caused total unrepairable damage.
Lookout old boy coming through
Please send us any links if you do any Ivy Bridge testing
