4.13 Soldering Components Close Together
This exercise starts the step-by-step construction of a transistor circuit. If you install all
components in the last required position from the first, you will reach a completed circuit
step by step.
Sometimes, individual components must be soldered close together or their connections
require soldering them in directly adjacent bores or lands. Since there is little space, the
soldering tip and solder must be placed precisely. Handling is all the more difficult the
more components are already soldered in. Therefore, work from the PCB centre towards
the edge and first solder on low components like resistors and diodes. High components
like transistors and LEDs are the last. When soldering components that are close together,
avoid touching adjacent parts with the hot soldering iron.
Also observe that the liquid solder does not generate any conductive connection to adja-
cent components or contact areas.
