Disadvantages of pneumatic fluid dispensing include:

Precise control is impossible to achieve
The pulsed air supplied to the syringe stresses the material. The turbulence created by the blasts of air heats the adhesive in the syringe which causes the viscosity to decrease. With pre-mixed and frozen syringes the thawing process begins to cure the adhesive, increasing viscosity and making dispensing difficult.

The material isn’t in a “released” state
To control flow and minimize fluctuations, technicians often use the smallest needle size. This adds to the problem by stressing the material and adding more viscosity problems.

Changing the homogeneity of certain materials
Adhesives with fillers begin to separate out, and suspended particles can actually become compressed along the inner walls of the syringe. This results in variations in viscosity in the mix and affects flow behavior and bonding properties.

“Over” or “Under” dispensing
“Over” or “under” dispensing happens because of problems with control. Over dispensing wastes material and often makes stenciling of encapsulated components impossible. Under dispensing can lead to components falling off or shifting position before or during reflow.

The amount of vacuum cannot be pre-set
With pneumatic systems, the amount of vacuum- and hence, the draw back- cannot be adjusted.

Air contains moisture
When the pulsed air is blasted against the plunger in the syringe, both the air and moisture can be forced around the sides of the plunger and into the material.

The most notable alternative solution in solder paste dispensing was the auger valve. However, auger valves have severe limitations. Using an auger valve, the material is stressed by the motion of the auger. The result can be a change in both temperature and homogeneity, which can impact viscosity and the amount of solder paste dispensed as well as the quality of the dot.

The best option for solder paste dispensing is AirFree® linear drive technology. AirFree® linear drive technology provides high repeatability without concern for viscosity and the volume of paste remaining in the syringe. The amount of solder paste delivered (dot after dot after dot) is consistent. The technology also provides significant savings in material cost due to the ability to pre-package syringes with larger amounts of paste than is possible with other types of dispensers.

The Fishman SmartDispenser® Solder Paste Dispensing Series offers advanced automation control through visual verification and real-time reporting at the point-of-dispense. It utilizes proven AirFree® technology and offers accurate and repeatable liquid displacement without the headaches associated with pneumatic systems requiring trial and error adjustments of knobs and dials. The SmartDispenser® solder dispensing system combines Fishman’s AirFree® technology with a Windows® 7 operating system and a platform for downloadable software, service and training Apps. It is ideally suited for solder dispensing applications in the electronics, medical device, automotive, telecommunications and defense industries as well as for other general manufacturing processes.

The SmartDispenser® CA delivers all of the benefits of the SmartDispenser®. The difference is that the SmartDispenser® CA is completely contained in the polypropylene syringe. Genius™ CA dispensing components are designed specifically for cyanoacrylate dispensing, achieving optimized performance for all CA applications. Genius™ PosiLok™ pistons and tip caps are manufactured with a proprietary plastic that inhibits bonding between the cyanoacrylates and polypropylene. The positive displacement system removes unreliable moisture-filled air from the dispensing process ensuring good bond strength. Genius™ syringes are available in 4 sizes and the thickwall design eliminates flexing. Precision molded zero degree taper assures smooth flow.

The patented AirFree® SmartDispenser® CA Linear Drive System delivers the same amount of adhesive during every dispense with the highest repeatability possible from a syringe reservoir, assuring maximum bond strength. There are three SmartDispenser® CA Linear Drive Systems available: SDAV-CA Linear Drive System, MDAV-CA Linear Drive System, and LDAV-CA Linear Drive System. The SDAV-CA (small dot any viscosity) model should be used for dispense volumes between 0.00023 & 30cc. It is ideal for small dot and long bead dispensing. The MDAV-CA (medium dot any viscosity) model is for dispense volumes between 0.00045 & 30cc. It is ideal for medium dot and medium to short bead dispensing. The LDAV-CA (large dot any viscosity) model is for dispense volumes between 0.0009 &30cc. IT is ideal for large dot dispensing. All models maintain repeatability 6 to 10 times greater than pneumatic systems.

Key performance features and capabilities of AirFree® fluid dispensing include:

Operation without air supply
Fluid dispensers traditionally relied on pneumatics to “push” the material out of the barrel reservoir which caused problems such as inconsistent dots due to variations in air pressure and changes in viscosity due to build-up. Fishman Corporation revolutionized fluid dispensing with the SmartDispenser® fluid dispensing system that utilizes AirFree® technology to eliminate the variations associated with air pressure dispensing. With the SmartDispenser®, exact amounts of adhesive can be dispensed without variations in applied pressure, without problems with moisture and changing viscosity, and without degradation in repeatability as the amount of material is reduced within the syringe during dispensing.

Linear actuator-driven mechanical lead screw
The linear actuator-driven mechanical lead screw lowers a piston on command from a microprocessor control unit to push the material through the syringe and out the tip. An interference fit between the plunger and the syringe ensures against leakage of material and loss of pressure.

Screw that travels along its axis
This is the key to the smooth operation and precision movement of the fluid dispenser, which separates the Fishman AirFree® fluid dispensing technology from other dispensers on the market.

Mechanical action of the lead screw
With the SmartDispenser®, control is achieved with the linear drive system and not by the size of the needle. The proper needle size can be used for the material and the application so the adhesive is in a relaxed state and dispenses smoothly. Materials with fillers remain homogenous. Tunneling does not occur, and without air, no infusion of moisture or other contaminants is possible. Precise dispensing is achieved, even with changing viscosity.

Evenly applied force
When an adhesive is compressed between an auger thread and the housing as it moves through the pump, changes to the properties of the material are possible. Fishman AirFree® fluid dispensing technology ensures that force is applied evenly to the material across the face of the plunger and dispensing occurs without crushing the adhesive.

Intelligent microprocessor
Companion to the AirFree® fluid dispenser is an intelligent microprocessor that provides precise control over the volume output, based on the prescribed dispense rate and the known inside diameter of the syringe being used.

The LDS is a system that is made up of two parts: the dispensing gun and the control unit. The dispensing gun is the working tool. It can be held in the hand or mounted to a frame. The control unit is the “brains” of the operation. It automatically ensures the precise amount of output from the gun each and every time it is triggered.

Construction of the Patented AirFree^® Linear Drive System is as follows:

A precision stepper motor housed in a precision molded electronic enclosure. A stainless steel plate with stainless steel interlocking tabs connect the syringe retaining ring to the gun housing. A precision machined lead screw runs through the motor and connects to the syringe piston via a luer lock thread. A nut located in the center of the motor spins in response to charged magnetic poles holding the screw still, thus moving in a linear motion. A clam shell piston stabilizer clamps around the luer lock thread, nestling into and around the piston and preventing it from cocking left or right while under pressure. This positive lock connection assures no flexing occurs under pressure. Flexing leads to pressure loss and pressure loss destroys repeatability between one fluid deposit to the next.

Operation of the Patented AirFree^® Linear Drive System is as follows:

The LDS drive system, driven electrically, ramps to full speed protecting fluid formulations and their bonding properties. An intuitive, volume-based menu system controls the firmware driving the Linear Drive System . A universal power supply converts 110v or 220v into the needed current automatically. Combine the stable voltage menu system with the Linear Drive System and one dispense program will perform exactly the same on a second SmartDispenser^®. Depending on the fluids formulation and syringe filling process dispense repeatability between +/-5% and +/-2% is possible.

The SmartDispenser^® Linear Drive System (LDS) replicates the fluid dispense process from one SmartDispenser^® to another SmartDispenser^® to ensure repeatability and less waste.

The pneumatic fluid dispensing process is still used across many industries, however air-driven dispensers are on a decline because they often result in reliability and quality control problems including variations in viscosity and dot size, dripping and waste of the material, and changes in homogeneity. These conditions challenge the accuracy and repeatability of fluid dispensing systems.

Fluid dispensers that rely on air pressure are unreliable due to fluctuations in air pressure. Pressure drops and volumetric displacement are a result of the plumbing between the air compressor and workstation. When violent air pulses come into contact with the assembly fluid it can result in turbulence, heat, and changes in viscosity. This undermines the ability of air-driven dispensers to deliver prescribed amounts of material consistently. Fluid dispensing accuracy and repeatability is challenged.

Fortunately there is now an answer to the problems that plague conventional dispensers which eliminates any and all use of pneumatics which is the root cause of the problem. Systems based on air-free technology are gaining wider use in dispensing adhesives, solder paste, and other fluids.

Fishman’s answer to fluid dispensing problems caused by air pressure is the SmartDispenser^®. It features a proprietary dispensing system that offers a superior level of process control without the limitations of other types of dispensers on the market. The SmartDispenser^® uses AirFree^® linear-drive dispense technology to achieve the highest repeatability when dispensing assembly fluids. The fluid handling technology allows manufacturers to establish one dispense program globally, withi no change to fluid deposits. It ensures that a dispense in the U.S. will perform exactly as a system in China as long as the same program, assembly fluid, reservoir, and dispense tip are employed in both locations. In addition, SmartDispenser^® AirFree^® technology eliminates fluid waste, rework, rejects, and costly air compressors to maximize profitability. The SmartDispenser^® fluid dispensing system AirFree^® dispensing series includes a handheld benchtop, benchtop automation, and an automation system.
