How do you replace parts on a Motorola transistor?


Quick Answer

Repairing or replacing Motorola transistor parts is generally limited to replacing lead posts and semiconductors in older transistors, but newer models have no repairable parts. Motorola transistors played a large role in making radios available in automobiles in the late 1950s since they eliminated the need for radios to have vacuum tubes. These early transistors had three lead posts leading into an enclosed housing that contained one or more semiconductors or crystals.

The only replaceable parts on these transistors were the lead posts and semiconductors, but low costs made replacing a transistor more feasible than repairing or replacing a part. Electronic stores such as Radio Shack once sold kits that contained epoxy and materials for replacing semiconductors, but these were generally for educational purposes. Advances in integrated circuitry and silicon chips made these transistors obsolete. Newer chips developed in the late 1960s and 1970s housed multiple transistors on silicon chips that became increasingly smaller until handling individual transistors became physically impossible without special machinery. Since the 1970s, transistors have been too small and had no replaceable moving parts.

The early personal computers, such as the IBM models introduced in 1979, contained a microprocessor chip containing approximately 29,000 transistors. The Intel microprocessor chip used in the Apple iPhone 6 released in 2014 contains over two billion transistors. These microprocessors require tightly controlled, dust-free environments and robotic machines to produce. It is physically not possible to replace a single transistor, much less a transistor part.
