How not to fry a board
Moderator:Moderators
Ok i just want some tips as i will be starting the SNESp next week and i want to know what to advoid so i dont fry my board. (i already know the evils of static electricity because my graphics card blew last week because of it)

Don't put power in backwards (It IS a polarity sensitive circuit)
Don't bridge components unless they are supposed to be (IE: You CAN bridge a switch so its always on, but you CANT bridge a capacitor, CPU, etc etc etc.(You can also bridge a fuse, but its not exactly recommended))
I know you already know this, but be VERY careful of static. Its Satan in disguise.
Don't overheat (With your soldering iron) chips, traces, the PCBoard itself (It can cause traces to lift. I've done it.), transistors...Better yet...Just don't over heat ANYTHING. Solder carefully.
Careful of dripping solder. If you drip solder on the board, make sure you remember to get it back off before you plug it in. You make have accidentally bridged two points.
Careful with hot glue. As nice as it is, its an insulator. It keeps heat in. To put it this way; A transistor will produce heat. A small transistor will producing heat too, but mush smaller amounts. Smaller amounts to US. But to the transistor, its still a massive amount of heat. And if you cover it in hot glue, that heat isn't being released. So your over heating it. Granted, it may not get any hotter than 90 degrees F. But to the transistor...Its a sun. I may be hard to comprehend, but thats the most laymen way I can put it.
Hope I was of some help.

Most important thing of all, not mentioned so far - before opening the console, and after disconnecting the power from the mains; YOU MUST turn the system on for a couple of seconds and off again. You will probably see the LED shine for a moment and then go off. If you don't do this, there will be residual voltage in the capacitors which will fry your board as soon as you open it up and handle the board / solder to it. Turning the system on and then off stops this happening as the residual voltage will have gone.
I forgot to mention this. Yes. Its true.bacteria wrote:Most important thing of all, not mentioned so far - before opening the console, and after disconnecting the power from the mains; YOU MUST turn the system on for a couple of seconds and off again.

But be careful; Making sure you turn the switch off when plugging in batteries. Double check your polarity before turning it on. Think of it as a failsafe. One more safeguard on frying the board.
