Flex circuit assemblies are important. If you’ve found us, you probably know what they are already. But if you’re just stumbling in (or looking for a quick read) feel free to learn a little more about the flexible circuits you frequently rely on. Or, for more info on how we work with flex circuit assemblies, you can always contact us today.
Have you ever heard of a flex circuit assembly? If not, chances are you used one recently – in fact, you could be using one right now.
Flexible circuits, otherwise known as flexible electronics, use mounted electronic devices on flexible plastics such as PEEK, conductive polyester, and polyimides. But why? By mounting electronic parts on durable and flexible plastics, manufacturers benefit in a number of ways.
First, flex circuit assemblies allow manufacturers to tightly assemble electronic packages where connections are being made on every face of the product. Also, when it comes to products like a cell phone that flips open, flexible circuits make that motion possible. Additionally, in products or components where space and weight is a concern, flexible circuit assemblies help cut back on the requirements for both.
But how does a flex circuit work? A basic flexible circuit is constructed of a flexible polymer which is then laminated to a sheet of copper. This thin sheet of copper is then etched to product a circuit pattern on one or both sides. Interconnections are made adding plated-through holes to the piece – allowing for compatibility with almost any part. Sometimes, an overcoat is added to give insulation and protection to the circuit for products subject to a wide range of operating conditions. Once the flex circuit is created, it can bend as need while still conducting the necessary electricity to power the device.
Flexible circuit assembly can also accommodate single or double sides circuits, surface mountings, shielding, and multi-layer designs for flexible and rigid circuits when devices need it.
Flex circuit assemblies are frequently used in products where rigid circuit boards are uneconomical, too heavy, or a design constraint (such as in the case of a product that requires flexibility). Presently, you will find flex circuit boards in many of the electronics you use in your day to day life, from cameras, computer keyboards, LCD products, and more.
Many times, OEM’s require very small tolerances and extremely accurate micro-vias. A “vertical interconnect access” (via) combined with the obvious prefix micro, makes a microvia that allows for flex circuits needed in small, precision instruments like those used in operating rooms.
With this capability, many businesses that provide electronic contract manufacturing flex circuit assembly specialize in flex circuit assemblies that enable the use of the high-tech precision electronics that make a serious impact on our lives. Whether they impact us by enabling us to connect with our friends and loved ones around the with portable and reliable smartphones or keep us alive with precision medical equipment. Some other products and tools containing flex circuit assemblies include: music players, radios, phones, cameras, medical instruments, radios, computer parts, aircraft components, military equipment, and more.
Whether you’ve thought of what makes your many compact electronics possible or not, there you have it. A small insight into flex circuits and electronic contract manufacturing flex circuit assembly. It truly is one of the technologies we rely on every day without ever knowing it.
