Tips for choosing SMT placement machine nozzles
It is well known that there are various types of SMT placement machine nozzles on the market, which can be classified by material into tungsten steel, diamond steel, ceramic, plastic steel, plastic, aluminum, iron, etc. By shape, there are round holes, square holes, V-shaped ones, etc. By size, there are even more types. How to choose the suction nozzle is a problem that many SMT newcomers want to pay attention to. Here, I'll give you a brief explanation on how to choose the suction nozzles for SMT placement machines
Nozzle material
Tungsten steel nozzle: Tungsten steel nozzles are sturdy and durable, but they tend to turn white easily. Once they turn white, just apply an oil-based pen and they can still be used.
2. Ceramic nozzles: Ceramic nozzles never turn white, but they are very brittle and prone to breakage. Careful use can prevent or reduce the occurrence of fractures.
3. Diamond steel suction nozzle: Sturdy, practical and never turns white, but extremely expensive and not cost-effective.
4. Rubber nozzle: When the surface of the material is uneven or the material is sticky, a rubber nozzle is suitable. However, the lifespan of a rubber nozzle is not long. It is recommended to purchase more rubber nozzles as a spare when ordering rubber nozzles. When the nozzles are worn out, you can directly replace them with rubber nozzles yourself.

The size of the SMT placement machine suction nozzle
For standard-sized materials, the specifications of the suction nozzles are basically fixed. Taking Samsung SM as an example, 0805 material corresponds to CN065 suction nozzles, 0603 material corresponds to CN040 suction nozzles, etc. When some materials are neither too big nor too small and have strange shapes, it is necessary to customize suction nozzles.
Nozzle shape
The shapes of the suction nozzles include square holes, round holes, V-slots, etc. Custom-made suction nozzles usually have flat suction points selected based on the shape of the material. Some are made into elongated suction nozzles that extend into the concave plane of the material for suction. Some are made into a square shape according to the edge of the material. Some have flat ends but an uneven middle, in which case a bridge needs to be built. Some materials are sticky and difficult to discharge. In such cases, some grooves should be made in the wall of the suction nozzle or a rubber head should be made.
