Product overview
This FPC/FFC hot melt dispenser is an inline, production‑grade system designed for flexible printed circuit (FPC) and flat flexible cable (FFC) adhesive tasks including underfill, sealing and connector potting. Key features include syringe cartridge or heated feed line supply, precision motion gantry, fast‑response valve/pump options, optional 2D/3D vision alignment, recipe storage and MES/PLC interfaces for traceable production.
Problem → Cause → Solution
Problem: In FPC/FFC assembly, inconsistent bead volume or misplacement causes shorts, delamination and rework.
Cause: Variability arises from unstable adhesive temperature, long feed paths, slow valve response and lack of inline alignment/verification.
Solution: Deploy a closed‑loop inline dispenser with heated syringe/feed, fast metering valves, vision‑guided alignment and MES recipe control to stabilize viscosity, meter accurate volumes and ensure repeatable placement.

Applications
- FPC/FFC underfill, bead sealing and connector potting in display, touch and flexible module assembly.
- Local adhesive for stiffener bonding, connector fixation and cable end sealing.
- Small‑batch R&D to inline production transfers requiring recipe traceability.
How it works
Load syringe cartridge or connect heated feed line and set target temperature.
Load or select recipe; conveyor indexes part and vision (if fitted) aligns fiducials.
Metered dispense: valve/pump deposits dots/beads per path while gantry follows programmed trajectory.
Verification & logging: optional AOI inspects bead geometry and placement; process data logged to MES.
How to choose
Adhesive type: for filled/thixotropic adhesives choose heated feed + piston/peristaltic pump; for micro‑dots choose piezo valve.
Throughput needs: match valve/pump and nozzle size to cycle time and pattern density; request measured UPH on your part.
Placement tolerance: choose vision alignment if placement tolerance ≤ ±0.02 mm.
Integration: confirm required MES/PLC interfaces and I/O mapping for inline synchronization.
FAQ
Q: Which adhesives are recommended for FPC/FFC applications?
A: Low‑viscosity thermally stable hot‑melt and epoxy adhesives are commonly used; for filled adhesives validate viscosity‑temperature curves and select pump/valve accordingly.
Q: Can the system run continuous inline conveyor operation?
A: Yes—the machine supports indexed and continuous inline modes; conveyor I/O synchronization is configurable.
Q: Does the machine support recipe traceability with MES?
A: Yes—recipes can be pushed/pulled from MES and batch data logged for traceability and SPC.
