Solder bar
A soldering bar is an electromechanical component that consists of an insulating carrier material (for example, made of hard paper ) and several soldering lugs - usually arranged in pairs . The solder bar also serves as a mechanical support point for the soldered-on electronic components - such as resistors , capacitors , coils and transistors . These bars also make the electrical solder connection . In the past, the soldered-on components were mostly lightweight components, while heavier components in the past were often mechanically connected directly to the device by means of clamps and the electrical connection to these components was usually made via cables.
The solder bars are built into the devices with spacers, for example. The spacers ensure safe electrical separation between the pressed-in solder contacts and the device. From the beginning of commercial electronics until the 1950s, numerous electronic devices, especially radio receivers , were built with it, and then they were replaced by printed circuits . Solder bars are rarely found in commercial devices today, they are occasionally still used in the production of prototypes and in the hobby sector.
