PCB assembly joints
Repeated soldering points and accessible joint patterns on circuit-board assemblies. Component height, board support and nearby temperature-sensitive areas need to be considered.

Robotic Soldering Machines for Electronic Assembly
Programmable soldering brings repeated joints into a defined machine sequence. Yoson coordinates point, drag and multi-head soldering configurations based on the assembly, joint access and required production flow, with sample-joint evaluation before final technical confirmation.
Application fit
Where this solution fits.
Review the joint drawing and current process, confirm the solder and flux information, plan the tool path and fixture, then evaluate representative joints. Acceptance criteria should describe the required result rather than only the machine movement.
Terminals and connectors
Dedicated fixtures for consistent presentation of terminals and connector assemblies. Provide drawings and samples showing how the parts are held before soldering.
Parallel or multi-fixture production
Multiple fixtures or heads can be reviewed when the process and throughput justify them. The layout must still allow loading, tip access, cleaning and inspection.
Configuration decisions
What determines the equipment.
Joint access and fixture
Check the approach angle, working clearance and support under the joint. A fixture must locate the assembly while leaving the necessary soldering and inspection access.
Process recipe
Review solder-wire specification, flux, temperature settings, dwell and movement together. Suitable values depend on the joint and material; they are confirmed through process evaluation.
Inspection and integration
Define how the finished joint is accepted and whether fume extraction, vision checks or line interfaces belong in the equipment scope. Requirements should be agreed before the station is built.

Process reference
Compare the operation with your process.
Use the operating reference to explain a similar step in your production. Send your own part and process video so differences in fixtures, handling and acceptance can be reviewed.

Common project questions.
Can a process video replace physical samples?+
A video is useful for initial review. Representative samples may still be needed to evaluate access, heat transfer and the resulting joints before confirming the configuration.
Is multi-head soldering always faster?+
The benefit depends on the joint pattern, loading sequence and process balance. The full station cycle must be reviewed rather than comparing head count alone.
Can the station connect to an existing line?+
Conveyor, fixture-transfer and control interfaces can be evaluated. Share the existing line layout, transfer method and signal requirements.
