Re: [Elecraft] Heat Sink Compound Question
Chuck……. Great information for the K3 Radio’s Ray WA6VAB K3 From: Charles K0MV Sent: Tuesday, March 29, 2022 6:30 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Heat Sink Compound Question Hi Tony, I posted this reply last November. This topic appeared on the list previously from last October "sticky thermal pads for K3 LPA Mosfets". One of my LPA Mosfets went bad in my K3s. I saw a comment on the reflector about these devices failing and I'm guessing the heat sink design is subject to production variation. I used to design switching power supplies. Reliability is a very strong function of device temperature so keeping cool is important. I hate to take time to fix stuff, so try to fix it so it never fails again. I replaced both of them but also improved the thermal design. As Ray WA6VAB mentioned, I got mine from RF Parts. The epitome of outstanding thermal design is the Intel I7 processor heat sinking. The processor and the heat sink are polished, shiny, and very flat. The best thermal compound is a silver based paste included with the heat sink. It does 100 watts over a couple of square inches so very low thermal resistance (remarkable!). Any gaps compromise the performance. There is a very good tutorial on this here: https://forum.digikey.com/t/thermal-interface-materials I examined the bottom cover and found the surface of the metal to be uneven and this inhibits heat transfer (raises the thermal resistance). I also found the bottom cover may not be perfectly flat. Moreover, the typical flexible thermal pads are not as good as alternatives. I polished the K3s bottom cover where the heat sink attachments are with a Dremel tool and polishing pad and automotive rubbing compound, a fine abrasive. You can see it becomes more shiny and I verified that with a microscope. I got a larger diameter flat washer for placing under the screw head on the outside of the K3s. This places compression over a larger area to help heat transfer. Digikey part number H734-ND. Since Elecraft has different board revisions you should check that the tabs of the MOSFETs can be grounded. If so, then there is a type of thermal pad that is very good. From the data sheet: High-PERFORMANCE, cost effective thermal interface material Used where electrical isolation is not required, Tgon TM 800 is ideal for where electrical contact and thermal transfer are desired. High thermal conductivity of 5 W/mK in Z axis and 240 W/mK in the X-Y axis. This type not only has low thermal resistance across it, but also a low thermal resistance in the plane of the pad helping to spread the heat out. Digikey part number 926-1471-ND manf part number A15037-112. Use just a very small amount of the silver based thermal compound. I run FT8 so the duty cycle is 50%. It's been several months and no problems (1000s of QSOs)--at least yet!

[Elecraft] K4 and Delivery Delays
I thought long and hard about a K4, but couldn't stand the idea of a two year wait for whatever reasons given. If design decisions and supply chain choices cause you to lose customers, it says that Elecraft needs to have a long moment to get their house in order. Or, they will fall into line with TenTec, Collins and many other American companies that have folded tent. We all went through the pandemic, and worked around it. So, I ordered a Flex 6600M and it was delivered in 8-days. No two year wait. They have something figured out. I was also assured the PGXL 1500W amplifier ships in the same time frame. Go figure. Bill N4LG You may have missed the two-year long pandemic that, among other things, has sickened multiple Elecraft employees, caused many to work from home, and disrupted supply chains, to the extent that nearly all the major carmakers can't get chips to put cars on dealers lots.

I have two. I purchased the 1st one when I ordered upgrade items for a K3. The 2nd one (AFAICR) came free with the K3S. I sold the K3, but the hat didn’t go with it!

Re: [Elecraft] A hat was saved (totally apropos of nothing)
Wow! At least you got a hat with your radio. I put down my $1500 deposit on a K4 at the 2019 Hamvention and waited almost 2 and a half years to finally receive the radio. My very first Elecraft purchase ever. When Madelyn emailed me to say the radio is ready to ship, I asked for at least a K4 lapel pin button, like the ones given away at that hamfest, or possibly a baseball cap to be thrown in with the shipment. The radio was shipped with nothing but exactly what I ordered. I guess I should be pleased with that, after the EXTREMELY LONG WAIT. Unfortunately, I was never made aware of any K4 lapel pins while at that hamfest, and it was never mentioned and I never saw anyone handing them out. I was kinda disappointed. I realize it was not all Elecraft's fault. So many issues came up during that wait period, but I also feel like the radio was announced and sold before it was truly ready for production. All that money and EXTENDED wait, and not even a "Sorry about the long wait... here's a little token of our appreciation" That would have been appreciated. Flame off.

It’s now safely in my part of the closet.I thought I was going insane because I couldn’t find it. 72, Rich Hurd / WC3T / DMR: 3142737 Grid: FN20is __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to weave...@usermail.com __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to w...@comcast.net __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
