neutralzz 0 Report post Posted July 28, 2006 just did up a little bit of soldering.. decided to test my fat tipped iron on this fine job.. argh!! quite a bit of suspense.. considering the cost of this board.. have to be very careful.. roar the shop i went to for 1% caps were out of 11k, no choice decided to series a 10k and a 1k.. i use quite a lot of soldering grease to ensure maximal wettability.. cleared up the mess with a piece of tissue which explains that white bit stuck.. thank god it was wonder solder.. with grease it becomes very wettable so i just need to let the solder flow down the wire and seeps into the hole forming a good joint had quite a bit of excess solder.. inverted the board and applied the iron to let the excess solder flow down the excess wire before cutting the excess wire bits off so far so good.. all connections intact.. tested all soldered parts for connectivity with my multi meter using other unsoldered points that are along the connective tracks.. the caps will go on after i've done most of the fine bits.. hope i dont botch them up as they are the costliest bits of this.. madness Share this post Link to post Share on other sites

neutralzz 0 Report post Posted July 30, 2006 hmm.. did the signal lines... had an idea actually.. decided to strip my spare belden 89259, used a penknife to slit along the insulation gently to expose the shielding and core.. removed the core from the shielding.. and slotted in 2 strands of 20 awg p-occ wires... soldered the shielding to the signal ground on one end.. i.e. rca end wrapped the teflon insulation back.. and heat shrinked the whole thing.. so its now sorta.. 1 copper shield and 2 teflon shields for the signal line.. hope it turns out well Share this post Link to post Share on other sites
