Flexible Circuits & Assemblies
Our Flexible Circuits are the core of Printed Electronics, and allow various conductive inks to be screen or digitally printed directly onto various substrates.
Flexible Circuits are the most versatile and dynamic backbone of the electronics industry. ALMAX has been designing and manufacturing flexible circuits for over 20 years.
As a result, our flexible circuit capabilities are top of the line. With our expertise and guidance, we can help bring your flexible part to life.
The Benefits of Flex Circuits
Flexible circuits, also known as FFC’s or FPC’s, are a special type of durable circuit that can be bent into any desired shape without being damaged. Flexible circuit technology is highly reliable and provides key benefits beyond other available methods. These include reduced packaging requirements, high wiring density, shock and vibration performance, high-speed signal performance, harsh environment performance, and significant cost savings. They can also be manufactured using a multitude of various substrates and conductive materials. Additional benefits include:
Conductive Materials for Flexible Circuits
A flexible circuit is a vast accumulation of conductors bonded to a thin dielectric or insulating film. In a copper flex circuit, a very thin sheet of copper is laminated to a flexible film substrate then chemically etched away, leaving copper traces. Copper flex circuitry construction offers significant benefits, including improved creasability, greater conductivity, and better adhesion.
Conductive inks, as the name suggests, are inks that conduct electricity. They are commonly seen in capacitive and membrane switches, Radio Frequency Identification (RFID) tags, touch screens, biomedical and electrochemical sensors, Positive Temperature Coefficient (PTC) heaters, electromagnetic interference/radio frequency interference (EMI/RFI) shielding, and more. ALMAX has been manufacturing flexible circuits with conductive inks for over twenty years with inks such as: Micro-Silver, Nano Silver, Nano Copper, Silver-Silver Chloride, PEDOT:PSS, and Carbon.
Silver/Silver Chloride is typically used to create sensing electrodes in many medical and environmental device applications. It is commonly used for electrochemical measurements, such as in pH meters, electrocardiography (ECG), electroencephalography (EEG), Transcutaneous Electrical Nerve Stimulation (TENS), or in cathodic protection corrosion systems for sea water environments and more.
PEDOT is remarkable amongst conductive polymers in that not only is it Flexible and Printable, but also Transparent and Conductive. Usually, conductors are opaque due to their chemical composition. PEDOT, on the other hand, permits light to pass through, making it the perfect selection for applications that combine a need for both backlighting and circuitry, such as pairing LEDs with Capacitive Touch Switches.
