Home etched boards

2017-07-05

 been years since I etched my own PCB’s.

I’m trying to get back in to it, using the toner transfer method.

The above is a double sided board for an opamp based I/V and filter for a PCM1794.

I also made Pavouk’s I²S input, 10* TDA1543 board. Mainly to test a different transfer paper.

More to follow…

If anyone has a good trick to get the toner to bond with the copper and still be able to “easily” remove the transfer paper, please let me know.

I have etched a wm8740 board with separate voltage regulators for analog and digital supplies. As my skills (and printer) are limited in how fine pitch I can get away with, I opted for LT1963 adjustable IC’s as voltage regulators.

It is not very pretty, but I am still learning how to best use the toner transfer method.
