- 0210BB / 16BB / 22BB+ layouts
- 03MBB and SMBB stringing
- 04Customer-specific high-density interconnection
ENGINEERING CONSIDERATIONS
What to define before the trial.
Mechanical window
Define tensile strength and elongation around handling stability, cell stress and downstream layup behavior.
Coating system
Select alloy, coating weight and flux compatibility against the customer's wetting and peel-force criteria.
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 cell and busbar architecture
- 02Lock diameter, alloy and mechanical window
- 03Submit samples with dimensional data
- 04Run stringer and peel-force trial
- 05Approve packaging, lot ID and mass-production controls
TECHNICAL FAQ
Questions buyers ask before sampling.
Can the diameter be customized?
Yes. Final diameter, tolerance and mechanical properties are defined through sample approval and line validation.
Is this ribbon suitable for TOPCon?
It is designed for mainstream and advanced module layouts including TOPCon, subject to the customer's cell, flux and stringer process.
What data is supplied with samples?
The sample package can include agreed dimensional, resistivity, tensile, elongation and coating-control information.
