Kartoshka Posted October 5, 2008 Author Report Share Posted October 5, 2008 my dark evil plan originally was to screen the mb6582 panel graphics for myself.... but then making of cnc g-code failed.if you know someone with proper cnc/lasercut in TLV area, lemme know!p.s. no probs with making you cool boards.. you have to drill them, that's the pain!

Kartoshka Posted October 6, 2008 Author Report Share Posted October 6, 2008 second day photos and conclusions. Adding solution Boards thrown into the etchant Too Fresh solution: time adjusting time to wash them off Rinsing waters Washing out the asphalt with (crude?) oil Ready to laquer, 1mm drill and parts num screening (if any exist ;D)But... hey, stop. The most important thing i learnt today... is that not screens born equal. Precisely... There are screens you can not use with delicate images which require precision. Like, screening clothes is different from screening 0.025mm lines The key is Density... ;)I used 2 different screens with different densities. THE BETTER RESULTS (APART KINDA EATEN TRACES WHICH CAUSED BY INCORRECT TIMING WITH SOLUTION) WERE DELIVERED BY MORE DENSE SCREEN, APPARENTLY 90-100, while second screen (the papareil -bigger- boards and others) was estimated as 70-75: it gave us more rude and coarse results, inacceptable for even moderated QC. More than that, quantity of asphalt matters as well: less you put onto the screen, better results you get.and the scan to evaluate said above:link to higher resolution image (x4)... Proving the silkcreen density importance, we gonna make NEW boards tomorrow with all-new-out-of-the-bag screen marked 120 . should be even better then. ;)Vlad Quote Link to comment Share on other sites More sharing options...
