FULL PCB MANUFACTURING Quote

Sheldahl T1647

Sheldahl T1647 is a polyimide coverlay that features acrylic adhesive. It is a high-temperature, flame retardant, and modified polyimide film. In addition, this flex material is ideal for use in applications where temperature resistance and solderability are very important. Also, this material offers a superior manufacturing process that enables a stable dimensional stability.

Sheldahl splicing tapes

Sheldahl manufactures uncoated slicing tapes that ensure maximum bond strength. This tape comprises reinforced polyester film.

Sheldahl G1932

This Sheldahl material is a polyimide copper laminate featuring epoxy adhesive. The epoxy adhesive is flame retardant. Also, Sheldahl G1932 is a RoHS compliant epoxy adhesive helps to make double sided and single sided composites. The G1932 is specially designed for use in flex circuit applications where flame retardant system is crucial.

Sheldahl  T9032

This is a flat cable insulating tape used for manufacturing flat flexible cable and some adhesives that help users balance product performance during lamination processes.  This tape serves as an insulator against electricity and as such protects circuitry and users. Also, it is heat-resistance and easy to apply to different wires.

Sheldahl Novaclad HDI

This high density interconnect (HDI) material is special built on adhesiveless laminate that integrate photolithography, abd vacuum deposition to ensure fine-line circuitry. Also, Novaclad HDI that comprises laser drilled micro vias can resist extreme temperatures, vibration, and chemical exposure. Also, you can control the copper thickness of this material. Therefore, this gives it an added advantage.

Improved dimensional stability

Sheldahl flex materials feature great dimensional stability. This means that these materials don’t change in sizes and dimensions in response to temperatures. In addition, they maintain a stable dimension even in elevated temperatures.

Exceptional chemical resistance

One of the best properties of Sheldahl material is the ability to withstand chemical exposure. Chemical resistance is a crucial property of  a PCB material. This is because some PCBs function in environments exposed to various chemicals.

High bond strength

This material features very high bond strength. Bond strength describes the force needed to separate two adjacent board layers by a force upright to the material surface. Also, PCB materials with high bond strength tend to perform well in high-performance applications.

High thermal conductivity

Heat can easily pass through Sheldahl flexible circuit materials. Thermal conductivity helps in measuring the ability of a material to transmit and absorb heat. Also, Sheldahl material is a good thermal conductor as it allows heat to pass through it. Furthermore, it easily absorbs heat from its surroundings.

Applications of Sheldahl Material

Sheldahl is a well-known flex PCB company that produces circuits and materials for various industries. Its products are suitable for use in some applications.

Medical

Sheldahl materials are commonly used in medical devices like X-ray machines, CT scans, and heart rate monitors. These materials offer great flexibility and performance. Also, they offer high chemical resistance and dimensional stability.

Automotive

The automotive industry integrates Sheldahl PCB material in some parts of vehicles. For more than 50 years, Sheldahl has been delivering flexible circuit board materials to the automotive industry. Also, Sheldahl produced the first flexible circuit used in the ’65 Ford Thunderbird. You will find these materials in exterior and interior lighting, sensors, and infotainment systems of vehicles.

Aerospace and military

Initially, Sheldahl supplied a wide range of its laminated products to the aerospace and military industries. These industries relied on Sheldahl PCB material. Aerospace and military devices are usually subjected to very harsh conditions. Therefore, it is crucial to integrate materials that can withstand extreme temperatures in the production of these devices. Sheldahl is one of such materials you can rely on.

Consumer electronics

Another use case of Sheldahl flex materials is in the manufacturing of consumer electronics. Consumer electronics such as smartphones, wearables, television, and more comprise Sheldahl materials. In computers, flexible laminates are widely used. Also, calculators, cameras, and exercise monitors comprise Sheldahl materials.
