@flux: it is in my “wire solder”:
- SN60, PB40, - FLUX: CAJ 2% (or OAJ 2% — not so clear, because prin is old…) “www.aimsolder.com made in canada”
@ Washing: i got me a medical grade Isopropanol - and took it 100% poor without H2O - and gave the 2 PCBs several long bathes, and brushes, i shaked it - so the stucked cornes and holes can get rid of it… its very clean now … my cleanest pcb so far… BUT without luck.
@Din Part: no problems with double triggers, or fantom Button presses, very clean in mios-studio.
— what i notice is when i press for example button 1, then button 5 begin to ghost…. that is for all buttons on booth boards.
— on the first board the 4th and 8th button is ghosting brighter then all others - and they do it always.
I checked specially the parts for the 4th and 8th button where the ghosting is extrem — the diodes and resistors are ok, the transistors i cant say at the moment - because want to avoid to desolder them again - only for testing.
the rest of the pcbs are working great, specially the Transport-Board (play record…) no ghosting of course - because of no Matrix there?!
i tested the board with Midibox NG & the SEQ_R, and the SEQ_L script, and with the orginal SeqV4 & Seq_R config file, on booth firmware i have the same problem.
i video about all that - is at the moment uploading to youtube (of course as “not listed” 😉 )
