Explain 'solder bridging' as described in IPC-A-610.

Solder bridging is defined in IPC-A-610 as an unwanted connection formed between leads or conductive pads that can result in short circuits. This occurs when excess solder flows and creates a conductive path that connects two distinct points that should not be electrically connected. In electronic assemblies, this can cause malfunctioning of the circuit by allowing current to flow improperly.

Understanding solder bridging is essential for maintaining the reliability and performance of electronic components. Detecting and preventing solder bridging is a critical part of the soldering process to ensure that only intended connections are formed. Proper training and techniques in soldering can help minimize the risk of solder bridging, thereby helping to uphold the standards set by IPC-A-610 for acceptable quality in electronic assemblies.
