The world's first green product line in soldering technology
As the first manufacturer in the field of soldering technology, Stannol offers a complete product range under the name greenconnect, which focuses on the aspect of sustainability.
In the past, only the criteria of quality, price and delivery time counted, especially when purchasing tin. However, due to the strong demand for raw materials, working and living conditions in the mining areas are largely inhumane. The environment also suffers greatly from the uncontrolled and partly illegal mining of raw materials.
With our greenconnect products, we enable our customers to take a step further towards sustainable and ecological manufacturing.
The four areas of greenconnect
The sustainable greenconnect product range includes:
Fairtin solder – environmentally friendly, sustainable and fairly produced
The solder wires, solder pastes and solder bars from our greenconnect range all bear our Fairtin label. This means that primary tin from a guaranteed sustainable supply chain and from certified producers in emerging countries is used for these products. Alternatively, solders made from high-purity secondary raw materials originating from European production are used.
For Fairtin products, tin is supplied by producers that
- pay attention to the protection of the environment,
- respect international and national rights,
- fulfil their social responsibility for employees and locals – for example, by ensuring fair wages and adequate occupational health and safety measures,
- work against child labour, and
- act transparently.
Stannol works continuously with suppliers, monitors compliance with requirements and develops products further.
Flux – bio-ethanol instead of IPA
In our greenconnect flux, the previous main ingredient isopropanol (IPA) is replaced by bio-ethanol. Bio-ethanol consists of renewable raw materials such as straw and can be produced completely without fossil fuels via a fermentation process. This results in a significantly better CO₂ balance. Important for our customers: Extensive tests have proven that a 1:1 exchange of the flux is possible without changing the process parameters.
No requalification necessary
The high quality standard of our own products ensures that all materials can be used in the respective manufacturing process without any time-consuming requalification. This enables our customers to provide transparent information about the solder material used. As proof of the use of our sustainable products, all greenconnect customers receive a personalised, batch-related certificate.
Several large, well-known industrial companies now exclusively order Stannol products that carry the greenconnect label. Our commitment to the environment will also be further expanded in the future: From now on, only spools made of 100 per cent recycled plastic will be used for our solder wires.
The greenconnect product range
Solder wire – Kristall 611 Fair
Our Kristall 611 Fair solder wire is a halogen-activated flux solder wire that opens the process window in many places. A greatly reduced flux spitting in combination with a good wetting behaviour on poorly solderable surfaces are the highlights of this innovative product.
- made from fair tin
- low spitting behaviour
- leaves light no-clean residues
- very good wetting properties for fast soldering
- chemically modified resin that reduces health risks when using rosin-based fluxes
- mild smell
Areas of application
Designed for manual rework as well as for automated soldering equipment, Kristall 611 Fair allows to cover the different production needs in a modern electronics manufacturing. The flux meets the requirements of J-STD-004C standards and is classified as REM1 flux.
Solder Paste – SP2200 Fair
Our SP2200 Fair solder paste is designed for high volume, lead-free SMD electronics manufacturing. It contains a highly active L0 no-clean flux. With a special formula for excellent wetting, it meets the requirements for surfaces found in any volume production today. The small amount of residue left after reflow is bright, transparent, electrically safe and does not need to be removed.
- the solder powder is obtained from our Fairtin series
- very good printability after a long standstill of the printer
- Reflow under air or nitrogen possible
- high open time of the printed circuit board
Areas of application
The solder paste SP2200 Fair was developed for stencil printing. With the TSC405, TSC305 and TSC0307 alloy as solder powder in classes 3 and 4, the SP2200 solder paste can be used in all common open and closed printing systems.
Flux – EF350 Bio
The halogen-free activated No-Clean flux EF350 Bio guarantees excellent wettability on different surfaces (for example OSP, Ni/Au, HAL, chem. Sn and chem. Ag) with both lead-free and lead-containing solder alloys. By using renewable raw materials, a better eco-balance is achieved while maintaining the same high quality.
- 70 percent CO2 savings per litre (compared to conventional fluxes)
- universally applicable
- high solids content – fast wetting
- electrically safe residues
- excellent wetting properties
Areas of application
EF350 Bio is a flux with an extremely wide working range and can be used universally. It can be used for wave soldering as well as for selective soldering. EF350 Bio is well suited for use in spray fluxers, use in foam fluxers is also possible.
FAIRTIN alloys are only made of tin from manufacturers who pay particular attention to environmental protection, comply with national and international laws and fulfil their social responsibility when extracting ore and processing it.
- the tin used in our alloys complies with valid current norms and quality standards, therefore Fairtin does not have to be re-qualified
- you will receive a certificate as proof of your commitment and the use of our Fairtin products
When switching from lead-free standard alloys to Fairtin alloys, all existing settings remain the same!
