Next we'll do the two IC's, NE5532 dual op-amps. Remove one from the tape. Take some time to
inspect the device.
Similar to the diodes that you just installed, you'll notice that the IC legs are bent outwards and
downwards. You need to install the device with these legs in contact with the pads on the PCB.
Unlike through hole IC's, many surface mount IC's don't have a dimple or crescent embossed into
the casing to identify the location of pin 1. Instead, they have a sloped face on the side with pin 1.
The other side has a vertical face. If you look at the silk screen for the two ICs on your PCB, you'll
notice that it has both the usual dot adjacent to pin 1, but also a second line along one side. This
second line represents the sloped face side that the slope should be placed against.
