Tips for SMT Newcomers on Selecting Pick-and-Place Machine Nozzles

As we all know, SMT pick-and-place machine nozzles produced by manufacturers on the market are diverse. They are classified by material into tungsten steel, ceramic, diamond steel,plastic, aluminum, iron, etc.; by shape into round hole, square hole, V-type, etc.; and by size into various specifications. However, how to choose a suitable nozzle is a concern for many newcomers in the SMT industry. Here is a detailed explanation on how to select an SMT pick-and-place machine nozzle that suits your needs.

Nozzle Materials:

1.Tungsten steel nozzles: Their advantages are sturdiness and durability, while the disadvantage is that they are prone to whitening. SMT newcomers can choose tungsten steel nozzles. After whitening, they can be coated with an oil-based marker and continue to be used.

2.Ceramic nozzles: Ceramic nozzles never whiten, but they are relatively fragile and easy to break. Care must be taken during use to avoid or reduce breakage and extend their service life.

3.Diamond steel nozzles: They are sturdy, easy to use, and never whiten, but they are expensive and not cost-effective.

4.Rubber-tipped nozzles: When the surface of incoming materials is uneven or sticky, rubber-tipped nozzles can be used. However, the service life of rubber-tipped nozzles is not long. It is recommended to purchase more spare rubber tips when ordering rubber-tipped nozzles, so that the worn tips can be directly replaced with spare ones during use.

Nozzle Sizes:

For standard-sized materials, the nozzle specifications are basically fixed. Taking Samsung SM as an example, 0805 components correspond to CN065 nozzles, 0603 components correspond to CN040 nozzles, etc. For some materials with non-standard sizes, custom-made nozzles are required.

Nozzle Shapes:

Nozzle shapes include square hole, round hole, V-groove, etc. Custom-made nozzles are generally designed based on the shape of the material, selecting a flat suction point. Some are made into elongated nozzles to reach into the groove plane of the material for suction; some are made into a loop shape according to the edge of the material; some have flat surfaces at both ends and a bridge structure in the middle where the surface is uneven; for some sticky materials that are difficult to place, grooves are opened on the nozzle wall or rubber tips are used.
