Hermes Posted March 4, 2004 Report Share Posted March 4, 2004 Hello everyoneI am building a quad midibox SID and I was wondering about the following subject:If I etch my own pcbs, using Thorsten' s *.pdf files, will that affect the sound quality of the SID synth?Would it be better to order the pcbs from mike' s shop? I am looking for a cost effective solution - I know how to etch pcbs, but I don' t want to jeopardize the sound quality!!Thanks in advanceBest regardsDimitris (Hermes) Quote Link to comment Share on other sites More sharing options...
pay_c Posted March 5, 2004 Report Share Posted March 5, 2004 No, not at all. The main quality points that influence it are the PSU (!! Use TK´s solution) and the grounding (best u use a aluminium case which is completely grounded - and don´t make sandwiches (meaning two or more PCBs over each other).The only thing what can happen you at the beginning is that you have to experiment a little with the etching (up to now about 20 - 10 % of my boards were rubbish - all other were good and work up to now).Greetz!

arumblack Posted March 6, 2004 Report Share Posted March 6, 2004 Maybe do some small practice boards.I screwed up at least 3-4 boards beforeIgot it right. check the forums for a thread called faster etching, for some tips. Quote Link to comment Share on other sites More sharing options...

Guest analouge Posted March 16, 2004 Report Share Posted March 16, 2004 Hi!I've done some etching before and it isn't that hard... It wasn't a big cuircit though, just a simple FM transmitter I had some fun bugging neighbours during bingo hour on the radio to overide the signals - pretty fun :), though it came to a rough end when a local police man found out about it :)... I did it the really old fashioned way - drawing with pen on the board, then etched it... up and down - up and down and so on... hehe.. The most difficult part by making the pcb was to design the pcb layout from the schematics I got from a friend... I was about 11-12 yrs old back then, and I didn't find it very difficult to do, but then I am a fast learner... And it takes a little bit too long for me to etch as I am a very impationt person from time to time... especially the boring process of the actual etching :)HOWEVER... all I ever did was to design pcb's by hand, and the whole computer design is new to me... so I just wondered; HOW do I get to print the pcb layout that TK made in size 1:1?

arumblack Posted March 16, 2004 Report Share Posted March 16, 2004 if you can find a pdf of the circuit, just make sure the options shrink large pages to fit and expand small pages to fit , or anything like that are not checked. then do a test and hold a socket up to it and be sure the pins line up.you can try the same with any other image, but i find the pdf worked best for me.

pay_c Posted March 16, 2004 Report Share Posted March 16, 2004 Check the portal, I think there are some .tifs and so to download and print them directly.(If not pls remind me to put them there...) ;)Greetz Quote Link to comment Share on other sites More sharing options...
