Hi Peter I had this problem several years ago and cured it by replacing the whole driver board. It was cheaper from ICOM than the cost of a new FET! Its a real shame they don't sell them anymore. I noticed on my new board a resistor AND an inductor had been placed in series in the gate circuit...perhaps to prevent the driver from self oscillation at VHF/UHF. Mine didn't have heat transfer paste either. Nice work Peter, thanks for sharing. Steve G4EDG

Great work again Peter. I envy your attention to detail as always. I guess you're not cheap, but worth every penny. Your customers should know they get the best work humanly possible... IC-7000 is such a small and tight packed radio with a lot of power. Even with a little mismatched antenna there will be a lot of heat generated everywhere, things like this are bound to happen sooner or later.

Hi Peter, another great job. Thanks for sharing. Especially soldering the MOSFET on this heatsink, I think it is nearly impossible with standard soldering equipment.(about 30 W iron). A few words about the "power modification"... I know the owner of this IC-7000(he is a member of our chapter) and he noticed the excessive outputpower from the beginning(misalignment from Icom, he bought this TRX new and he definetely didn´t cranked it up) , he always used this TRX at 80% of the maximum power or less. So I´m of the opinion, that the failure is caused in the missing thermal paste, missing heatsinks of the predrivers and thereby caused selfoscillations.

As a manufacturer, It is amazing the cost for the service department to get with the engineering department to approve the drawings (correct rev. ..etc) then give them to the purchasing department to contact the vendor for a small order qty so he can find an approved vendor willing to do a small qty. Oops then I have to receive it and setup a "slow moving" stock location for them. Now the following year finance will tell you to get rid of slow moving so you have to justify it every financial audit. Ah almost forgot I need to have LCM for the part so need an engineer to go into the LCM and MRP system and set it up correctly so the receiver knows where to put it. For a prototype part it is much simpler but when you have to put it into inventory all of the boxes need checked or you won't be able to find the part when needed. There are good reasons for the Peters of the world that can simply make it happen for a price.

Anyway, to me this radio is piece of crap sold for a crazy amount of money giving the user nothing which could make him/her happy.

Couple of observations. NOT CRITICISMS! One, the heat sink thing between the MOSFET and the heatsink itself looked like a stamped out part. Is the Source of the mosfet soldered to that thermal link? Those stamped parts are typically anything but flat, unless someone has taken the time to lap them on a surface plate, or even a piece of tempered glass. You couldn't make a worse thermal interface if you tried. Now maybe it's just the camera and / or lighting, but it didn't look good. Secondly, that is not a complicated board. I think anyone with even a little bit of skill and experience laying out circuit boards could use something like Express PCB and end up with a suitable replacement. It's not rocket surgery. Get 10 made, keep 2 for oneself, and sell the others on Ebay or something. High power rf is what I do for a living BTW. We're about 2 or 3 generations beyond the BLF-278 now using LDMOS parts if anyone is wondering.

what you do is pipe in some propane so it jets up through the fan, then if you run it on six volts to slow the fan down, and when supply an ignition source, you can toast your weenies in style, without having to get under the hood of the pick-up to put aluminum foil on the manifold. Plus it;s real pretty at night.

I've often wondered how heat sink compound actually works - it looks as if we are putting in an extra layer of thermal insulation of some kind, preventing metal to metal contact (which must be the best heat sink possible). So does anybody know what the heat sink compound is made of and how does it improve the transfer of heat away from a component?

Thanks for the link - very interesting but it would be nice to have the thermal conducitvity values without the paste to compare...@@TRXLab
@stargazer76444 жыл бұрын
@@fardellp The big problem is when putting two castings together like in the case of the driver module, neither surface is flat. So there are lots of tiny air voids between the metal surfaces. You only have metal to metal contact in a few high places. Thermal compound fills in those voids and fixes that with a heat conductive paste.

Well no as if it would have been replaced we should see at least some residues of the old compound but it was totally clean..

Hello Peter. Is there any chance I send you my IC-7000 driver board and replacement MOSFET for you to replace the transistor? I lack the gear and skills to do it myself.I would probably cause more damage if I tryed. The board looks a repairable. Not too much charging going on. It too has the resistor in place to keep it from self-destructing. xD I haven't been on the bands for far too long since this my only HF rig. If you are able to help me out let me know how to contact you on shipment and pricing. 73s DL1FAB

Thanks Peter for another Good video, a bit disappointing to see inside these brand name products, how they left out the thermal compound on a known overheating area of the circuit. what quality are we really getting when we pay a premium price for a brand name product ?
