Nozzle material.
1, Tungsten steel nozzle:
Tungsten steel nozzle strong, durable, but easy to white, not afraid of trouble friends, or SMT newcomers can choose tungsten steel nozzle, white on the oil-based pen coating, you can continue to use.
2, Ceramic nozzle:
Ceramic nozzle never white, but very brittle, easy to fracture. Careful use can avoid or reduce the occurrence of fracture.
3, Diamond steel nozzle:
Strong, good, never white, but very expensive, not cost-effective.
4, Rubber-tipped nozzle:
When the surface of the material is not flat or the material is sticky, suitable for the use of rubber-tipped nozzle, but rubber-tipped nozzle life is not long, it is recommended to order rubber-tipped nozzle, buy more rubber-tipped head spare, when the nozzle head is worn, you can directly replace the rubber-tipped head on their own.
Nozzle size.
Standard specifications of the material, nozzle specifications are basically fixed to Samsung SM, 0805 material corresponds to CN065 nozzle, 0603 material corresponds to CN040 nozzle, etc., when some materials are not small, strange shape, you need to customize the nozzle.
Nozzle shape.
Suction nozzle shape has a square hole, round through, V slot, etc.. Some of them are made into elongated nozzles, which can be sucked into the groove plane of the material, and some of them are made into a return type according to the edge of the material, and some of them are made into a plane at both ends, and the middle is not flat, so they need to build a bridge. Some materials are sticky and not easy to put in the material, so we have to open some grooves in the wall of the nozzle or make it into a rubber head.
