there is nothing wrong with using clamping pressure for the interface loading, similarly PSI is a valid method of quoting that clamping pressure.

Don't confuse Force with Pressure. They are different.

Did you take your nit picking pill today Andrew! 🙂

I did say that it is a clamping force in my note, I just typed pressure in first line. I also did say they were different by virtue of stating one as a force and one was pressure. I just got the terms juxtaposed along the way.

Thank you for your critical eye and appreciation for perfection in the details. 😉

Hello everyone, we are doing modestly well on the interest so far shown on the wiki. As a reminder I have asked that you revisit the wiki and convert your interest into numbers so I can gauge how close we are to hitting some minimum numbers.

I know GB's are never easy and I have done a few, maybe it's the economy but I would have thought we would have had more members on board by now.

I also get the impression (not to be paranoid) that there are members that feel this is a money making venture for me. This gets me a little worked up as I actually lost about $60 on the last one I did due to an error on my part calculating Pay Pal fees. My fault, but some members kicked in extra to cover my boo boo and that is what I like about this group, there are some really cool people in this hobby.

Anyway let's see if we can spread some good PR around about this GB and I will see if I can drive prices down even further.

Regards

Anthony

PS. No one has taken me up on my offer to do a personal Thermal Plot for them for thier configuration as yet.

after reading through the whole thread and trying to figure out what i would need to get to build a suitable f5 chassis, i am still at a loss to try and figure it out (and what it would cost)...
Maybe part of the problem is that there are too many options to figure it out...that's why there are repeated posts regarding what the total cost would be.

F3 chassis

I am on for the large chassis for an F5 but I am still thinking about an F3 since I have the PCBs and the Lovoltechs. Anybody know the thermal requirements?

Can I get by with the smaller chassis or the new version of the smaller?

I believe an earlier post suggested I would need the same as for the f5 but I wanted to be sure.

Thought I might be able to save some money on my second one and thereby be able to afford two - although two matching chassis might look pretty cool

Following along with the current pricing laid out in the wiki if we meet the Min. MOQs invovled.

The most basic Chassis which is 4 Heat Sinks, 4 Blank Raw Panels, and mounting rails would be $187 CAD plus 3% Pay Pal, applicable taxes and shipping costs.

To get the $187 basic kit you need only select 4 of the 5"/6" heatsinks and 1 small Chassis kit. It is that easy. 🙂

Each option you add after that adds to the cost.

Tom what is the amount of power disspated by the devices on the F3 and how many devices per channel? Or what voltage are the devices running at and how much bias Current?

Pricing Review - Following along with the current pricing laid out in the wiki if we meet the Min. MOQs invovled.

1) This configuration will also serve as a basic F5 Chassis with the right Hexfet and Insulator choice.
The most basic Chassis which is 4 Heat Sinks, 4 Blank Raw Panels, and mounting rails would be $187 CAD. To get the $187 CAD basic kit you need only select 4 of the 5"/6" heatsinks and 1 Chassis (2 x 10" or 4 x 5"/6").

2) The more substancial version of a basic kit would be $221 CAD, for this you get 10" Heatsinks and the large Chassis kit. To get the $221 CAD kit you need only select 4 of the basic 10" heatsinks and 1 Chassis (4 x 10").

3) If you want the Heatsinks already machined for assembly, then you would pick 4 of the 10" Drilled & Tapped and 1 of the Chassis (4 x 10"). This kit would be $253 CAD.

Each option you add after that adds to the cost.

All pricing is subject to 3% Pay Pal, applicable taxes and shipping costs

Well it looks like we cracked a few critical MOQ's to make this GB closer to a go.

10" profiles are go for MOQ
Chassis selections are go for MOQ
Optional Top Plate is a go for MOQ
Optional Anodizing is a go for MOQ
Optional Clear or black anodize is a go for MOQ

The following are not currently a go for MOQ.

5" or 6" Profiles (Either / Or) are not a go for MOQ (by a longshot)
Optionl Rear Panel Kit are not a go for MOQ (by a longshot)
Optional Rear panel from Front Panel Express are not a go for MOQ (5 away) Could increase the price for a smaller MOQ.

What the group needs to do now is decide on a deadline for transfer of funds and placing our orders. I say 5 weeks at the latest and 3 weeks at the earliest.

Regards

3 weeks works for me. If the rear panel from FPE is a no go then we have to drill/stamp/file our own designs?
Click to expand...


Yes if the Optional Rear Panel was a no go then members would need to finish thier own back panels with the blank panel that comes with the chassis kit.

I will post the pricing for the current number of FPE Panels this evening.
