Hints On How To Use Precision Dispensing Kits

By Amanda Perry


There are various manufacturers that are inventing precision dispensing systems around the world. They have dispense valves, fluid dispensers, automated systems, syringe barrels, and precision dispense tips that are trusted to apply controlled amounts of oils, adhesives, sealants and other assembly fluids. When it comes with precision dispensing kits, individuals should select the best company that is supplying various products.

When dispersing filled resources and materials like conductive epoxies and solders paste, only use a smooth flow tapered tip. The internal profile will prevent it from clogging the fillers and less pressure is needed to apply it. The use will get better control and repeatability. Make sure to check the fillers first before applying it.

For low viscosity material, use a small diameter tip to increase the dripping due to capillary forces. A bigger tip would solve the issue. Try to use a pin transfer process. Dispense a tiny blob on the needle then transfer it where you desired it by just touching it down on the desired location.

If you are adjusting the setting or the pressure on the controller, make sure to reduce or down the pressure to the necessary levels before bring it back again to your range. If the deposit gets too small, change the tips right away. The material curing on the tips can reduce the flow. Never increase the pressure during the first instance.

For medium and low viscosity material, the controller should have a suck back option to reduce the mess, waste and reduce any dripping. Some of it will dry quickly than others, like the solvent base varnishes and clogging will be a problem. Try using tips that has high material capacity or a smooth flow tapered one. This will be required to make it work properly.

To create a great accuracy and control, use a valve. It will have the advantage of having an on and off of material flow. To prevent any flow of liquid use an inline filter on the air hose and place the barrel into a stand when not being used. Position the controller at a high level when working with it. Consider the tips that are flexible and angled to deal hard to reach areas.

Use a foot pedal that will initiate the cycle when searching for high location precision. If there is a bounce, use a finger switched that is mounted on the barrels. When dispensing CAs, consider using PTFE line tip to avoid any premature clogging and curing and reduce consumable expenditure.

There are many steps and procedures before an individual can master the art of using dispensing equipment. Also, there are many manufacturers and brands that are developing various products in the market today. It is essential to conduct research first before purchasing one. To be precise consult some professionals who are doing the procedure every day.

Budgeting will be the key. It is one of the most important factors that need to be considered carefully. When making a partnership with a company, individuals should choose the one that is within their budget range. They must only purchase high quality materials and equipment to use.
