This portable micro spot welding system combines a 900W transistor power supply, high‑resolution pulse shaping, and a visual alignment camera to support fast, accurate welding on FPCs, metalized films, battery tabs and other thin substrates. The unit offers programmable weld recipes, sub‑ms pulse control, adjustable electrode force and optional weld monitoring for production traceability. Compact and easy to relocate, it is suitable for R&D, benchtop production and small automated cells.
Problem: FPC and thin‑metal welding often leads to inconsistent joints, substrate delamination, or cosmetic defects that compromise yield.
Cause: Insufficient pulse resolution, uncontrolled electrode force, poor alignment and lack of recipe control cause excess heat and variable weld quality.
Solution: The 900W system provides transistor‑based current shaping, sub‑ms pulse control, precise electrode force and a visual alignment aid to minimize heat input, ensure accurate spot placement, and produce consistent welds. Validate and lock recipes for repeatable production.
Precision Pressure Head
Closed-loop pressure control with the error of ±5g, and real-time pressure inspection to improve the welding quality
Precision Transistor Power Supply
Closed-loop energy control to quickly achieve stable output and effectively prevent pad burns caused by energy diffusion
Ceramic Regrinding Module
Achievement of automatic regrinding after the set number of workpieces for spot welding reached
Visual alignment: operator or vision routine locates weld target and adjusts placement.
Recipe selection: load material preset or custom profile (current, pulse width, electrode force).
Electrode contact & force: actuator applies controlled force to ensure stable contact resistance.
Pulse delivery: transistor power supply delivers shaped current pulse(s) per profile.
Monitoring & logging: optional module records current/voltage traces and logs batch data for QA.
Required energy & thickness: match pulse energy to FPC foil thickness; use destructive/gravimetric tests for validation.
Alignment needs: choose built‑in vision if spot placement tolerance is tight (<0.1 mm).
Pulse resolution & modes: for micro‑spots, prefer sub‑ms resolution and multi‑pulse capability.
Electrode tip selection: small‑diameter copper tips for FPC; plated or tungsten tips for harder surfaces.
Portability vs. automation: select bench portable variant for R&D; choose cell‑integrated version for inline production.
Installation: bench or cell mount; connect grounded power, compressed air (if pneumatic actuator), and cooling. Follow ESD and grounding procedures for FPC handling.
Commissioning: run a sample matrix (material × thickness × electrode × profile) to create validated recipes.
Maintenance: clean/dress electrode tips regularly; replace worn tips and verify force sensor calibration monthly under production use.
Q: What is the minimum pulse width available?
A: Supports sub‑ms pulse widths down to 0.0005 s (0.5 ms) in selected configurations; confirm exact minimum for your model.
Q: How accurate is the visual alignment?
A: Onboard vision provides ±0.05 mm placement accuracy under standard fixture and lighting—field calibration recommended for different setups.
Q: Can the unit log weld traces for traceability?
A: Yes—optional weld monitoring records current/voltage traces and exports batch logs for SPC or MES integration.
