Copper thickness

I need a board that has 2 oz copper. I do not see any options for selecting this on the site; but I don’t see why there shouldn’t be.

Is it possible to have a board made up with 2 oz copper through this site?

Thanks in advance.

If it doesn’t have an option for it, it will be 1 oz only. It’s the standard thickness offered by every PCB supplier that I’ve ever dealt with.

I understand and agree, but every pcb manufacturer I have ever dealt with has the capability of doing 2 oz boards at an added cost. Is there a way to contact them and ask for this? I have tried emailing several times to support, but get no answer.

There will be approximately 50 amps going through the copper pours on my board and I really don’t think 1 oz copper will suffice.

You are confused about BatchPCB. It’s not like “every pcb manufacturer”. In exchange for low low prices, you have to give up flexibility and fast turnaround.

I could go on about the economics of their operation but I’d be mostly guessing - though I suspect correctly. It is what it is. I’m amazed that they keep it running.

Don’t like it? Don’t use it.

BatchPCB keeps costs down by putting boards together onto one panel. If they did offer a 2 oz copper option, you might have to wait several months for a panel to be filled up, as it isn’t likely to be very popular.

If it’s just a prototype and you must use BatchPCB I’d solder thick copper wire on the tracks, to increase the current-carrying capacity. I’ve done that before now, with a home-made PCB.

Reasonable answer.

The purpose of using 2 oz copper is to analyze how the board behaves. The board will be chopping the current at up to 4khz and I need to know what temperatures and electrical noise are emitted with the actual board design. There is also some very sensitive signal amplifiers on the board that wouldn’t be to happy either if I did what you said.

It won’t make any difference at 4 kHz!

50 amps of current being switched at 4khz with a current sense circuit. I would believe you if I hadn’t already ran into this problem with my last prototype.

You’ll need to find somebody to run a whole panel for you, as all standard quick turn services are 1 oz or 1/2 oz. Looks like that’ll be $110 at Gold Phoenix.

i would be down for some 2oz love if you need someone to throw a board on. To your panel if you get something from GP.

I think it will depend on how the PCB was designed. There shouldn’t be a problem, IMHO.

Good advice. $110 and you get a whole bunch of boards.

Hardly that much money these days, especially if you are actually developing a product. Normal turnaround is 7 days for a panel.

ADI as in the Australian company?
