grind off solder mask to get down to copper

Feb 20, 2007 1 Replies

Whats the chemical to take off the



solder mask , so i can solder to tiny



PCB traces ? I guess some acid that



wont harm copper .



Im Hacking the connector on a



game box "GP2X" .



I want my own , more robust connector



where all the USB lines are heading off



board in same direction .

BTW im also doin ARM 7 mcu's . Ill hook up a $44 ARM7 with USB as a "peripheral" to control KB and LCD , and pass on important stuff to a central ARM7 . I test code on the first ARM 7 , so the central 7 , can't crash . Central ARM 7 can boot the other in milliseconds . I will use low cost LCD ,BW , $10 from BG Micro . This project is unique , because it will never use text . There will be icons and images on the LCD to show you what is happening .



metal scourer or blade.

no such thing
