Description
Time pressure is a method of dispensing liquid materials (surface mount adhesives and gasketing materials) that uses air pressure applied to the top of a syringe to force material through a needle. The amount of time the air pressure is applied is directly related to the amount of adhesive dispensed. Dispensing materials in this manner is also known as "air over" dispensing, referring to air pressure over time or air pressure applied over a syringe.
