most of the times the programmers are naked because we need to program no. of microcontrollers on it.so everytime we can't open it.to make it ease you can cover with a plastic casing but make sure you wont cover the ic base.try my words dude it may be help full to you
Excuse my newbidity. What do you mean by programming the number of microcontrollers? Can you program more than one at a time? I guess that makes sense, since you might use different controllers for different functions? Can certain programmers handle different numbers of chips? How possible/practical would it be to program a chip on one board and then transfer it to the board it will be used on? Such as if I didn't want to build all of my robot/other boards with the ability/hardware to connect to a pc/programmer? Thanks so much for the help.
I think that santhosh243
was talking about programming them one at a time, but at several instances.
Technically, you could
construct a programmer and control software that could program different chips with different code concurrently, but since it wouldn't be usefull, nobody had.
Another type is called gang-programmers where you have a number of sockets to program all chips with the same code - they're mostly used in production.
To program the chips out of the target board, you either use a non-ICSD programmer (it used to be the only way back in time), or make a board with a ZIF (Zero Insertion Force) socket, a capacitor and a connector for the ICSD programmer (that's, more or less, how I program SOT-23 chips myself).
