Our Expertise
We can offer our experience and creativity to find solutions for new and existing products. Solutions in the sense of ideas, simulations, design proposals, samples and full production. We do not stop at winding a coil, but try to help the customer in finding solutions which will enable the final assembly to be done in a secure and economical way.
We are not restricted by order quantities; therefore single coils are not a limitation for us.
Depending on the needs of the customer and the foreseen production quantities several solutions are possible for setting up machinery:
• Manual, in case the quantities are low and investment should be kept to a minimum or time pressure does not allow the set up of automated machinery.
• Semi Automatic or Fully Automated, if production series allow or quality is an important parameter. If time is an important factor also a manual start of production is possible in parallel with the development of machinery.
Production in shifts is done for a demand which makes it necessary to meet the schedules of our customers.
Development
Coils and machinery
Coil development can be based on the experience of the customer with the addition of the experience at Swiss Coils. This can be brainstorming, designing, making technical drawings, simulations etc.
The coils can be new ones but also a redesign or improvement to make the coils more efficient, more economical, more stable in quality or better to handle during the assembly in the final application.
As smaller coils or coil wires are not always easy to connect to the rest of the electronics, we try to find solutions with the customer to make this less difficult or tiresome. SMD coils, connectors, tinned wire ends, flex PCBs, etc. are examples of improved handling.
If an existing coil cannot be altered for reasons like certified or approved product, it might be useful to concentrate on the production method, tools or equipment. Maybe there are ways to improve the used equipment to reduce costs or increase the quality output.
Designing custom production equipment and tooling is another service which we offer our customers. We design and assembly our own machinery and tooling to adapt the equipment to the requested coils.
Production
Coiling and Coil Assemblies possibilities
Just to give you an impression of what is possible, please note that it is just a list, maybe the solution you are looking for is not mentioned:
• Air coil, coil on a plastic bobbin, coil on soft iron, coil on ferrites or ceramics. Bobbins, soft iron and ferrites are coiling bodies which can have shapes and dimensions custom made.
• Wire materials can be copper, gold, silver, and alloys or coated with different materials. It can be single wires or litze wire.
• Wire size, from 8μm to 50μm (60AWG – 44AWG) are our preferred sizes, but we handle without any problems wires up to 350μm – 1mm (27AWG – 18AWG).
• Core preparations, annealing soft iron or ferrites, metallization of ferrites or ceramics, isolating cores and testing the quality before coiling.
• Finishing of coils to enable our customers to do the final assembly in a safe and economical way. This can be SMD in tape and reel, PCB assembly (FR4, similar or flex PCB's), connectors, lead wires or assemblies.
Connecting coils can be done by means of: soldering, tinning, thermo compression welding, electrical welding, arc welding, clamping or laser.
