Homebrew PCBs

"On Behalf of Brad"; 

Excuse my lack of knowledge.........but why is it important to use GIO epoxy-glass PCB material 
for the Lancaster TV typewriter circuit board(s). 

I remember this circuit was published in one of the hobby electronics magazines, and Lancaster 
subsequently published a paperback on building this item. 

Best,

Subject: [Homebrew_PCBs] Custom G10 copper clad 






Hey guys, 



Some of you might remember my queries about trying to get ‘correct’ looking single side copper clad PCBs for my vintage TV Typewriter project. I think I may have found a source, and I wanted your opinions to make sure I’m getting the right thing and can do what I want to do. 



The company I found is American Micro: http://www.americanmicroinc.com/g10-fr4/ 




According to Don Lancaster, he used ‘G10 Green’ boards. The above appears to be more or less that. Then what AM will do is add the copper cladding. It will cost me $400.00USD to yield the following: 



2 pcs – 9”x7” 

6 pcs – 5”x7” 

Plus remainder from sheet after cutting. 



Now, they are specifying .010” .. I’ve no idea what thickness the original TVT boards were, but I’m guessing they were probably thicker (.06ish?). Thoughts? 



I think the price is higher than what those pieces would cost via suppliers on ebay, etc. However I’m not bothered by that – the important thing for this project is that the boards look correct and have the correct grain and colour. In searching various single side PCB suppliers, the colours are too fancy or modern and the grain doesn’t look right. 



For a refresher, here’s a shot of one of the original boards: http://i1381.photobucket.com/albums/ah216/unclefalter/tvtboards2_zpssy81hx8b.jpg~original 



What do you guys think? Also, is there anything I need to be wary of in the process that they use to affix the copper cladding to the boards? I’m hoping to use the toner method of etching to get these done. 



Thanks again! 


Brad
