Install the Diodes

Be careful! Diodes have a polarity. Make sure the band on the diode aligns with

the banded end of the silk screen!

1N4004

Here's what the 1N4004 diodes look like (not to scale). The package type is known as a

DO-41. The body is black, with a white stripe:

D1-D3 have a glass body. They are packaged in the DO-35 package, a smaller package

than the 1N4004's.

Diode Notes

The designator D6 is not used.

Install the TO-92 Package Transistors

The TO-92 package looks like this:

In some cases, the leads may be bent as the picture above shows. In other cases, you may

have to spread the outside leads a bit to make it easier to insert them into the board.

Orient the transistor so its body shape matches the silk-screen outline. Leave the top of

the transistor about ½" off the board! The lead length prevents stress on the body and

keeps the transistor safe from too much heat during the soldering operation.
