Monday, March 10, 2014: A dispensing system can be inline or offline. Choosing an inline or offline system depends on the job to be performed. If the process is for small production batches, an offline dispenser unit will be adequate, but for high output placement lines, where the product cycle time is short, an inline system is necessary. For both inline and offline systems, there are three different dispensing methods—time/pressure, auger pump and piston pump. Today, SMT dispensing has evolved from early time/pressure pumps and auger valve systems to proven linear positive displacement pumps and jet technologies, and provides many options for balancing speed, volume control and price.
