Thermal window
Process development may support soldering below 170°C, but final settings depend on equipment, flux, cell and acceptance criteria.

PV RIBBON PLATFORM / HJT · 0BB · REDUCED HEAT INPUT
Low and ultra-low temperature PV ribbon
Sn–Pb–Bi alloy platforms developed for temperature-sensitive HJT and 0BB module processes where reduced thermal input and reliable wetting must be balanced.
Typical diameterØ0.20–0.30 mm
Alloy platform 1Sn43Pb43Bi14
Alloy platform 2Sn37Pb42Bi21
Alloy platform 3Sn32Pb42Bi26
APPLICATION FIT
Designed around the module process.
Final material selection should connect module architecture, equipment behavior and acceptance criteria in one controlled specification.
- 01HJT module production
- 020BB interconnection concepts
- 03Temperature-sensitive cell processing
- 04Customer-specific low-heat trials
ENGINEERING CONSIDERATIONS
What to define before the trial.
Joint performance
Wetting and peel-force targets should be validated on the customer's real cell and stringer rather than inferred from alloy alone.
Change control
Approved alloy, coating, flux compatibility and trial settings should be frozen together before production release.
QUALIFICATION PATH
From requirement to approved supply.
Use the customer's real cell, flux and production equipment to turn representative material data into an approved supply window.
- 01Confirm HJT / 0BB architecture and target temperature
- 02Select candidate Sn–Pb–Bi alloy system
- 03Evaluate wetting and cell stress on samples
- 04Run line trial and reliability checks
- 05Freeze alloy, coating and process window
TECHNICAL FAQ
Questions buyers ask before sampling.
Does low-melting alloy guarantee a lower stringer setting?
No. Flux, equipment profile, cell metallization and throughput all affect the usable process window.
Can Yansheng support trials below 170°C?
The material platform can support low-temperature development, subject to customer validation and the agreed qualification plan.
Which alloy should we start with?
The starting point depends on the target thermal window, joint-strength requirement, flux and storage conditions. We recommend selecting through a controlled sample matrix.
