JBC Tools RBA-A — Soldering Head for RobotThe JBC Tools RBA-A (SKU: RBA-A) is a robotic soldering head designed for automated soldering processes. Compatible with the JBC TR245 and TR470 soldering tools and the SFR Solder Feeder, the RBA-A provides two independent pneumatic movements — a Z-axis Lifting Unit for fast approach and retract, and a Nozzle Actuator for up to 90° rotation of the solder dispensing nozzle to facilitate automatic tip cleaning and cartridge exchange. Soldering iron angle is adjustable up to 30°. Requires an 18mm axis diameter for head assembly.Key Specifications Specification Value Part Number / SKU RBA-A Compatible Soldering Tools JBC TR245, JBC TR470 Compatible Accessories SFR Solder Feeder, GSFR Guide Kit, CLR/CLMR Tip Cleaner, CSR245/CSR470 Cartridge Exchanger Lifting Unit Stroke 20mm pneumatic stroke + 5mm spring buffer Nozzle Actuator Range Up to 90° rotation Iron Angle Adjustment Up to 30° Required Axis Diameter 18mm (0.315") Weight (head only) 588g (1.30 lb) Weight (with tool) 918g (2.02 lb) Dimensions 213 × 220 × 160mm Brand JBC Tools Key Features Pneumatic Lifting Unit — fast Z-axis movement into and away from the soldering position with 20mm stroke; integrated 5mm spring-loaded buffer stroke prevents PCB damage from excessive pressure during dwell time Nozzle Actuator — up to 90° rotation of the solder dispensing nozzle for automatic tip cleaning with CLR/CLMR Tip Cleaner and automatic cartridge exchange with CSR245/CSR470 Adjustable iron angle — soldering iron angle adjustable up to 30° for optimal approach geometry on different PCB layouts Dispensing nozzle orientation adjustment — configurable nozzle orientation for flexible integration into robotic soldering cells TR245 & TR470 compatible — works with JBC’s high-performance robotic soldering tools for precise, repeatable heat delivery Frequently Asked QuestionsWhat soldering tools are compatible with the RBA-A?The RBA-A is compatible with the JBC TR245 and TR470 soldering tools for robot. The TR245 is suited for standard SMT and through-hole soldering tasks, while the TR470 handles higher-power applications. Both tools mount directly to the RBA-A head assembly. Contact MTE Solutions for help selecting the right tool for your application.How does the spring-loaded buffer stroke protect the PCB?The RBA-A’s Lifting Unit includes a 5mm spring-loaded buffer stroke in addition to the 20mm pneumatic stroke. When the soldering tip contacts the PCB or component, the buffer absorbs any excess downward force — preventing the tip from applying damaging pressure to the board or component during the dwell time. This is critical for consistent, damage-free automated soldering on populated PCBs.How does the Nozzle Actuator enable automatic tip cleaning?The Nozzle Actuator rotates the solder dispensing nozzle up to 90° away from the soldering position, moving it clear of the tip cleaning station. The JBC CLR or CLMR Tip Cleaner can then clean the tip automatically between solder joints without requiring manual intervention or stopping the soldering cycle.What axis diameter is required to mount the RBA-A?The RBA-A requires an 18mm (0.315") axis diameter for head assembly mounting. Verify that your robot arm or gantry system provides a compatible 18mm mounting axis before ordering.
