Will Deoxit on a circuit board cause problems? In other words, is it conductive if it's touching components? I had to spray some switches that had a very tiny hole in a plastic covering, so the Deoxit got all over the board. I removed most of it with tissue paper, but there are traces of it beneath chips and other components, which is difficult to remove. I have also used some Q-tips to g...

Are there any guidelines for soldering 18g leads to Phosphor-Bronze? I assume that I should rough the Phosphor-Bronze up with some fine sand paper before soldering the wires to it, but I'm still concerned about the connection being. (I'm using Phosphor-Bronze for it's flexibility and electrical conductivity). Thanks. Darren Harris Staten Island, New York.

Years ago I adjusted a neighbor's generator so that it put out 60 cycles at 120 volts. I used a TEK 465B 'scope to look at the frequency. I saw the major 60 cycle waveform and then a lot of smaller waveforms at higher frequencies. I was told that these harmonics were typical of small generators. Today I am replacing the voltage regulator on a small generator and adjusting the governo...

In the simplified schematic for the Analog Devices AD825 there are two symbols I haven't seen before. One of them is an FET symbol and the other is a capacitor. These can be seen in Figure 32 on page 10 of the AD825 datasheet. The POS and NEG inputs each go the gate of FETs with this symbol. The capacitor symbol is labeled Cf and are connected to VOUT. Not sure if whay I'm looking a

Hi! Can anyone point me to the datasheet for an thgbmfg8c4lbair 32GB emmc flash chip? Searching only brings up a press release from 2014 and Toshiba hasn't replied to me yet. For now I would be happy with the pinout and I assume it's the same across the whole chip family and even different manufacturers. If you know a different source for a datasheet or pinout for any FGBGA Emmc chips...

I have an automatic opening trash can in the kitchen that runs off of batteries. I wanna run it with a wall wart. When the lid opens it draws more power than the 750 mA wall wart I tried using to power it could deliver. This makes sense. I don't want to use a bigger wall wart and I don't want to have betteries in it all the time to provide the current. I'm thinking instead of using a capaci...
