Frequently Asked Questions

What is the recommended storage temperature for JEAN-151 solder paste? +

For optimum performance and to achieve its minimum 12 month shelf life, JEAN-151 should be stored refrigerated between 4°C and 10°C. Ensure the paste reaches room temperature (approx. 6–8 hours) before opening the jar to prevent moisture condensation.

What is the stencil life of JEAN-151? +

This flux platform offers an exceptional 24-hour stencil life. It maintains consistent viscosity and rolling behaviour even in high-humidity environments, reducing waste during long production runs.

How should I clean the stencil and PCB? +

JEAN-151 is a No-Clean solder paste; residues are clear, non-corrosive, and probe-testable. If cleaning is required for aesthetic or conformal coating reasons, standard SMT stencil cleaners or IPA-based solutions work effectively.

What is the shelf life of JEAN-151 when supplied by DKL Metals? +

When stored correctly under refrigeration (4-10°C), JEAN-151 has a guaranteed shelf life of 12 months from the date of manufacture. DKL Metals ensures all batches are labelled with specific expiry dates for full traceability.
