The Advanced PV Ribbon Machine for High-Quality Copper Ribbon Wire Production

The PV Ribbon Machine, officially known as the Photovoltaic Ribbon Tin Coating Machine, is an advanced piece of equipment primarily utilized for the production of high-quality solar photovoltaic copper ribbons. This sophisticated machine is capable of applying a range of coatings, including various lead-containing and lead-free solders, as well as tin, tin-lead, and tin-lead-silver alloys.

It offers precise control over coating thickness, ranging from 10 to 60 micrometers. The machine exhibits a yield strength of ≤60-80 N/mm² (post-annealing) and a tensile strength between 190 and 250 N/mm², with elongation levels maintained below 25%. This ensures the durability and reliability of the ribbons produced, making it an essential component in solar technology manufacturing.

The Overview of PV Ribbon Machine For Producing Round Copper Wires

The PV ribbon machine developed and launched by Sky Bluer Industries China in July 2024, is designed to produce PV Ribbon round wires at a speed the customer requests. This device's exceptional performance, unique design, strong compatibility, and excellent free-flow characteristics make it the best tool for handling PV round wires at 400m/min. The production line includes a vertical active payoff part, two induction annealing machines, a tin-coated part, and two automatic precision winding machines. A human-computer interface, a PLC, a touch screen, and a servo system control the entire machine. During operation, each motor rotates at a reasonable frequency in order to ensure that the entire line runs smoothly and efficiently. Besides being easy to operate, safe, and reducing labor costs, it improves productivity and efficiency. 

What is PV Ribbon?

A PV tin-coated copper ribbon, commonly known as photovoltaic welding ribbon, is a type of connection material used to conduct electrical current and connect a photovoltaic module's cells.

Interconnect/Tabbing Ribbon Interconnect ribbon is a hot dip tinned copper conductor installed in photovoltaic/solar panels. This PV ribbon product has a relatively wide range of uses.The interconnect ribbon is soldered directly onto silicon crystal to interconnect solar cells in a solar panel. The interconnect ribbon carries the current generated in solar cells to the PV bus bar.

What is PV Busbar?

PV Bus Bar and PV busbar is a hot dip tinned copper conductor installed in solar panels. PV bus bar carries electric current from interconnect ribbons to the junction box. PV Busbar is also a strip material used for current transmission. It is usually made of metal materials with high electrical conductivity, such as copper or aluminum, and is very well conductive electrically. Power systems or high-power equipment usually use busbars to concentrate current between different branch lines or loads. Ensures the normal operation of a power system by carrying large currents and effectively disseminating current.

MBB

Size range:φ0.23 mm-φ0.43 mm

MBB are thin, rounded copper wires that do not require ribbons across the solar cell, rather they carry current from the fingers through to interconnecting ribbons outside the front surface of the cell.

Our PV ribbon machines are used to manufacturing multi-grid modules, such as 9BB, 12BB, 15BB PV ribbons, and others. Shaded cells will be reduced, series resistance will be reduced, current density distribution will be more uniform, module power will be significantly increased by 5 to 8W, and front silver will be reduced by 30%..

Conventional Interconnection PV Ribbon Machine 丨

Applied to conventional 4BB, 5BB modules. Suitable for automatic stringing machines, the interconnection ribbon is welded on the main grid of the cell to connect solar cells, collect and transmit solar cell current.

Ribbon Thickness:0.15-0.3mm

Ribbon Width:0.5-2.0mm

In this segment, our company is leading the field with its "tin-coated copper ribbon" equipment, which is primarily used to connect photovoltaic solar cells and serve as a conductive component. Our equipment has been purchased by a variety of countries, including Canada, Japan, Turkey, Malaysia, Vietnam, South Korea, India, Brazil, and the Philippines.

What Is The Best Flux To Use For PV Ribbon Machines?

When purchasing flux, you should consider its composition and performance indicators. Generally speaking, flux has three main components: activators, solvents, and surfactants. There are three main components of the flux: the activator, which promotes welding; the solvent, which dissolves and dilutes the activator and other components; and the surfactant, which enhances the wettability and fluidity of the solder.

Furthermore, when purchasing flux, you should also take into consideration its performance indicators, including viscosity, density, solid content, and pH. Viscosity refers to the fluidity of the flux, density refers to its mass per unit volume, solid content refers to the active ingredients in the flux, and pH refers to its acid-base properties.

Our technicians will also provide the most appropriate formula for the user's product, since new customers often don't know how to choose the best flux for their product.

What Type Of Annealing System Is Utilized In Photovoltaic Ribbon Equipment?

Induction annealing is an advanced heat treatment process that offers numerous benefits for modern manufacturing. Unlike traditional methods, our photovoltaic ribbon production line is equipped with state-of-the-art induction annealing technology, providing a safer alternative to circuit-based annealing methods by significantly reducing the risk of electric shock.
