The shape of the suction nozzle includes square holes, round holes, V-grooves, etc. Customized suction nozzles are generally selected based on the shape of the material, with flat suction points selected. Some are made into elongated suction nozzles that extend into the groove plane of the material to absorb, while others are made into a zigzag shape based on the edge of the material. Some end surfaces are flat, and if the middle is uneven, a bridge needs to be built. Some materials are sticky and difficult to place, so it is necessary to make some grooves on the suction nozzle wall or make a rubber head.
Standard specifications of materials and nozzle specifications are basically fixed. Taking Samsung SM as an example, 0805 material corresponds to CN065 nozzle, 0603 material corresponds to CN040 nozzle, and so on. When some materials are not large or small and have strange shapes, it is necessary to customize the nozzle.
1. Tungsten steel suction nozzle: Tungsten steel suction nozzle is sturdy and durable, but it is prone to whitening. If it turns white, apply it with an oily pen and you can continue to use it.
2. Ceramic suction nozzle: Ceramic suction nozzles never turn white, but they are very brittle and easy to break. Careful use can avoid or reduce the occurrence of fractures.
3. Diamond steel suction nozzle: sturdy, easy to use, never whitening, but extremely expensive and not cost-effective.
4. Rubber tip suction nozzle: When the surface of the material is uneven or the material is sticky, it is suitable to choose a rubber tip suction nozzle. However, the lifespan of the rubber tip suction nozzle is not long. It is recommended to buy more rubber tips as a backup when fixing the rubber tip suction nozzle. When the tip is worn, you can directly replace it yourself.
