Toner transfer or photoresist for SMD precision PCB

[JanErik]

Which would you recommend? I have previously used photoresist PCBs (with paper only, not transparencies) and a desk light, for hole mounted only, but people seem to be getting good results with toner transfer too. I need to buy a new printer anyway, should decide on laser or inkjet (better for transparency masks afaik).

With enough research and eventual practice, either method can yield excellent results.

I use toner transfer and have perfected my method, so I have no reason to ever invest in trying photoresist.

Toner transfer for PCBs having BGA packages on them!!!

If you opt for toner transfer, don't buy a Brother laser printer. They use a different toner, which won't let go from the paper or transfer film whatever you do. I had a Brother, and ended up buying a Samsung printer which solved all the problems.

Are Epson, Lexmark or Canon generally OK? How about color lasers, I guess they all have a separate black toner?

In my experience, photoresist is more repeatable, once you get into the proper exposure range by doing a test strip. I've had wildly varying results with toner transfer.

"SMD precision PCB" For what purposes? Audio, radio (microwawe) frequency (strip line, matching circuits, etc.), series (mass) production? For DIY I would recommend the use of a specialized milling machine.

DIY audio, as the forum is for .
But I am interested in trying some class D chips that of course have quite high frequencies, as well as some USB and SPDIF DAC chips.

What resolution would you say is required, is 600 DPI enough?
