Solder Paste
Solder paste is a critical material used in electronics manufacturing to attach electronic components to circuit boards. It's like a special glue made of tiny metal particles mixed with flux that helps connect parts together when heated. Think of it as the 'cement' that holds electronic components in place on circuit boards in everything from smartphones to computers. Companies look for people who can work with solder paste because proper application is essential for making reliable electronic products. Related terms you might see include "SMT paste" or "surface mount solder."
