Customers applying solder paste to small PCBs by hand. Making small repeat deposits of paste direct from syringe barrels containing dispense grade solder paste/ solder cream. Often replacing manual methods such as hyperdermic syringes. Objective is to eliminate costly waste and mess and ensure no rejects or rework.

Solution to use a TS350 digital timed pneumatic dispenser with 30cc barrels and smooth flow tapered tips. Reduces any waste by applying repeatable deposits that can be adjusted. Can store up to (10) memory time settings. Has a shot counter to show number of deposits made. Teach function allows correct deposit size to be found quickly.
