Solder paste dispensers
Solder paste dispensers for laser and induction
The soldering market is heading towards smaller and smaller applications. Therefore, the size of the solder wire and the influence of its contact with the components become a limit for the achievable process accuracy.
In order to ensure the excellence of its laser and induction processes with the smallest parts, mta robotics now has the capability to integrate solder paste micro-dispensing jet valve or traditional solder paste dispenser. This is integrated directly next to the soldering head, and within the same equipment.
The proximity between the solder paste dispenser and the soldering process ensures a perfect mastering of the complete process. Moreover, due to the complete integration of both process steps within the same automated equipment, the investment costs can be optimized.
3 reasons to choose the solder paste jet valve
- No accessibility problems due to non-contact solder paste dispensing process.
- Dedicated to very small dispensed solder paste quantity.
- No solder wire positioning or adjustment.
2 reasons to choose the traditional solder paste dispenser
- Used for medium up to large quantities of solder paste.
- Optimized cycle time and more effective process through combined solder paste dispensing and soldering operation.
Shipping costs incl.
Solder paste micro-dispensing jet valve
- Mainly dedicated for PCBs
- High precision dispensing of very small volume of solder paste
- Typical process: jet dispensing, i.e. jetting of solder paste combined with laser micro-soldering
Traditional solder paste dispenser
- Mainly dedicated for PCBs and connectors
- High precision dispensing of large volume of solder paste
- Typical process: solder paste dispensing comined with induction or laser soldering
The standard solder paste jet valve and traditional solder paste dispenser come well-equipped:
- Dispenser head structure
- Needle or nozzle according to application
- Purge bin
- Controller
Only for the traditional dispenser
