the top of the multimeter it’s for transistor test NPN&PNP this plugs it hard to used it it’s easy for a bran new transistor with 3 pin it’s tells the transistor is good or bad it’s hard for a scrap transistor that can test in this hole

Hello engineer, How can we identify the power pins of a microcontroller when it is connected to a heat sink and we do not have any specifications about it?

[@electronicsrepairbasics_erb]

Refer to its data sheet

[@protection4541]

@@electronicsrepairbasics_erb The data sheet can be removed due to the heat sink that is fixed with glue
