Types of Assembleon SMT nozzles

Assembleon SMT nozzles are available in different types and shapes to cater to diverse requirements. Some of the common types are as follows:

• IC nozzles: Assembleon IC nozzles are designed to handle integrated circuits. They have a rectangular or square shape to match the form factor of most ICs. These nozzles often come with laser-drilled holes for effective suction and placement of the ICs.
• QFN nozzles: Asymmetric nozzles, such as QFN (Quad Flat No Leads) nozzles, are usually used in no-lead package formats. They have a flat rectangular profile that fits tightly into the QFN's lack of leads. These QFN nozzles have precisely placed suction holes to accommodate the QFN's unique geometry.
• FP nozzles: FP (Flat Package) nozzles are created for placing devices with rectangular shapes and thin profiles. They have a thin and flat design that enables access to tight spaces between components.
• MLF nozzles: MLF (Micro Lead Frame) nozzles suit MRQ (Micro Quad Flat Package) components. They are made with a very fine suction hole size to enable effective pick-up and placement of small leaded devices. MLF nozzles are available in custom shapes to match particular component geometries.
• Odd-form nozzles: These are sometimes called specialized nozzles. They are designed for unique shapes and sizes that standard SMT nozzles cannot accommodate. They can have custom geometries and suction hole configurations.
• Mini nozzles: Mini nozzles are used for small surface mount components. They have a micro-scale suction hole diameter that enables precise pick-up and placement of tiny electronic parts.
• Vibration nozzles: SMT vibration nozzles incorporate a vibratory mechanism into their design. They use vibration to enhance component pick-up and placement. The vibration aids in the release of any trapped air or debris between the component and the nozzle suction cup.
