Within an SMT production process, most industry professionals would agree that solder paste printing is the most critical step. Many of the defects in circuit board assembly, such as excess solder or insufficient solder volumes, are a direct result of the solder paste printing process. Today, the solder paste deposition process is accomplished by printing, dispensing or most recently by jetting.
