What is a flexible flat cable?
Article reproduced, objections will be deleted
FFCs are flat flexible ribbon-shaped cables with multiple metallic conductors sandwiched between two insulating tapes. They are used extensively in consumer electronic products such as digital cameras, audio equipment, flat-screen televisions and office equipment. Shielded flexible flat cable (FFC) for automotive application use include high density mounting and fine lead pitch, improved flexibility and handing ability, high heat resistance PVC (105°C / 221°F) and low connection resistance.
Tin / lead alloy solder was formerly used on FFC conductors, but ongoing Restriction of the use of certain Hazardous Substances (RoHS) in electrical and electronic equipment requirements have led to lead-free FFCs. The drawback of applying lead-free electroplated tin to FFC conductors is that tin whiskers form in the area between the FFC and the connector. This can cause short circuits and arcing in electrical equipment. To address this, HCA has developed a tin-plated conductor with reduced tin whiskering based on applying a very thin “nano” coating of zinc on the electroplated tin.
Benefits of FFCs:
Reduced mounting costs. Since both ends of the terminals are machined, terminal machining preprocessing can be eliminated.
Excellent flexibility. The flat copper conductor encourages the CU-Joiner™ flexibility.
Custom designs are available to match the mounting method, the type and number of wires, pitch between wires, terminal length and insulation length.
Thirteen UL approved types available.

What are Jumper Cables?
Article reproduced, objections will be deleted
A car's battery is designed to perform one task very well, and that is to power an electric starter motor whenever the ignition switch is turned on. Once a car starts, an electric generator called an alternator assumes responsibility for most of the car's electrical needs, including recharging the battery for future starts. If the battery's power level becomes too low to turn the starter motor, the driver may have to use a second battery to provide additional power. The cables used to connect the auxiliary battery to the dead battery are called jumper cables, because they allow electrical power to "jump" from one battery to another.
Jumper cables are insulated lengths of heavy gauge wire which have large spring-loaded alligator clips on either end. Two clips are usually marked "positive" with the use of red insulation and plus marks (+), while the other two clips have black insulation and "negative" marks (-). This is a very important designation, since the positive clamps on each end of the jumper cables should only be attached to the positive terminals of the batteries, and the negative clamps should only be attached to the negative post or grounded area of the engine block.
In order to use jumper cables safely, the two batteries need to be in close proximity to each other, which usually means maneuvering the second vehicle end-to-end or side-by-side with the vehicle containing the dead battery. Jumper cables can be 10 feet or more in length, but the clamps need to be seated securely on the battery posts in order to get the best connection. Once the batteries are positioned properly, the driver can begin to attach the jumper cables to both vehicles.

USB: Everything You Need to Know
Article reproduced, objections will be deleted
USB, short for Universal Serial Bus, is a standard type of connection for many kinds of devices. Generally, USB refers to the types of cables and connectors used to connect these many types of external devices to computers.
What is USB?
The Universal Serial Bus standard has been extremely successful. USB ports and cables are used to connect hardware such as printers, scanners, keyboards, mice, flash drives, external hard drives, joysticks, cameras, monitors, and more to computers of all kinds, including desktops, tablets, laptops, netbooks, etc.
In fact, USB has become so common that you'll find the connection available on nearly any computer-like device such as video game consoles, home audio/visual equipment, and even in many automobiles.
Before USB, many of those devices would attach to a computer over serial and parallel ports, and others like PS/2.
Many portable devices, like smartphones, eBook readers, and small tablets, use USB primarily for charging. USB charging has become so common that it's now easy to find replacement electrical outlets at home improvement stores with USB ports built in, negating the need for a USB power adapter.
Who created the USB standard?
USB was developed collaboratively between Compaq, DEC, IBM, Intel, Microsoft, NEC, and Nortel. The USB standard is maintained by the USB Implementers Forum (USB-IF).
What is the current USB standard?
Since 2019, USB4 has been the current USB standard. Only USB-C connectors (rather than traditional mini/micro-USB) can support USB4.
What does 2.0 and 3.0 mean on a flash drive?
If you see a number like 2.0 or 3.0 on your flash drive, it refers to the version of USB that the device supports. Flash drives that support USB 3.0 can transfer data slightly faster, but it doesn't matter too much since most ports are backward compatible.
What are the advantages of USB over EIA-232F?
EIA-232F is an older connection standard that was replaced by USB. The USB standard is faster and consumes less power, making it much more efficient.

Ruling heralds the end of that confusing mess of charging cables
Article reproduced, objections will be deleted
Fishing through drawers to find the right charging cable may soon become a thing of the past, once a new ruling from the European Union (EU) comes into effect.
From 2024, all smartphones, tablets, cameras, headphones, portable speakers and handheld video game devices will need to use the standard USB-C charging port if they are to be sold in the EU. Laptops will join the list from 2025.
This may sound like just another boring technical ruling from the other side of the world, but the legislation may have consequences reaching much further than Europe’s borders.
It could mean the end of proprietary charging cables and ports, such as Apple’s iPhone Lightning cable and brand-specific laptop charging cables.
Manufacturing separate ‘EU-specific’ models of every device would be prohibitively expensive, and companies are unlikely to do it. Abandoning the EU market altogether is also not an option, not with over 447 million potential customers in some of the wealthiest nations on earth.
Changing all device sold everywhere to the standard USB-C cable would make the most economic sense for tech companies.
Just think, soon when borrowing a phone charger at a friend’s house, you won’t need to ask if they use an iPhone or an Android phone. You’ll be able to charge your laptop using any charging cable you can find, no matter what brand it is.
No longer will you need to have drawers full of anonymous cables for devices you’ve long disposed of, and can’t recall exactly what the cable was for.
The EU says it is implementing the changes principally to reduce e-waste, but also to make it easier for consumers to switch brands and products whenever they wish.
“The new requirements will ultimately contribute to the reuse of chargers and help consumers to save €250 million a year on unnecessary charger purchases,” the EU says in a statement.
“The new measures are expected to generate environmental benefits by reducing greenhouse gas emissions of approximately 180ktCO2e [kilotonnes of carbon dioxide or equivalent] yearly and reducing e-waste by almost a thousand tonnes yearly.”
Tech giants have predictably responded negatively to the news, with Apple calling the move “anti-consumer” and claiming it would actually increase e-waste.

What Is an RCA Cable?
Article reproduced, objections will be deleted
If you've ever connected a CD player or DVD player to your TV, you likely used an RCA cable. A simple RCA cable has three color-coded plugs extending from one end that connects to three corresponding colored jacks on the back of a TV, projector, or another output device. It carries audio and video signals from the component device to the output device (i.e. a television or speakers).
The RCA cable is named for the Radio Corporation of America, which first used it in the 1940s to connect phonographs to amplifiers. It entered popular home use in the '50s and is still in use today. The two most common types are composite video and component.
Composite Video RCA Cables
The colors used in composite RCA cables are usually red and white or black for right and left audio channels and yellow for composite video. Composite video is analog, or non-digital, and carries all the video data in one signal. Because analog video is made up of three separate signals to begin with, squeezing them into one signal reduces the quality somewhat.
Composite video signals typically consist of 480i NTSC/576i PAL standard definition video signals. It's not designed to be used for high-definition analog or digital video signals.
Uses for RCA Cables
Although an HDMI cable is a more modern way to connect devices, there are still plenty of opportunities to use RCA cables.
They can be used to connect a variety of audio and video devices, such as camcorders, to TVs or stereos to speakers. Most high-end camcorders have all three RCA jacks, so the signal entering or leaving the device goes through three separate channels—one video and two audio—resulting in a high-quality transfer. Lower-end camcorders usually have only one jack, called a stereo jack, which combines all three channels. This results in lower-quality transfers because the signal is compressed. In either case, RCA cables transmit analog, or non-digital, signals. Because of this, they cannot be plugged directly into a computer or other digital device. RCA cables connect amplifiers to all sorts of devices.
Quality of RCA Cables
Several factors affect the quality, price, and performance of RCA cables:
Materials: The connectors on RCA cables are often gold, silver, or copper. As you might expect, the gold connectors are the most expensive. They're also better than silver and copper connectors at preventing oxidation, but not as good at electrical conductivity. The silver connectors are best for electrical conductivity with the copper cables coming in a close second and the gold cables falling far behind. Other suitable materials are nickel, zinc, and tin.
Cable Length: Cable length has a negative effect on signal quality. Buy a cable that is only as long as you need it to make the connection for the best signal quality.
Shielding: A well-shielded cable delivers a better signal than one that lacks robust shielding.
The other end of the cable: If possible, match the material used in the other end of the cable to the material used in the connectors. Don't match tin with gold or silver with gold. Those combinations can cause problems because of an electrolytic reaction.
