Wide Application of PCBs
With the rapid development
of electronics technology, Printed circuit boards have been widely used in all
kinds of fields to satisfy more products requirements
1)Consumer
Electronics
Due to the high-volume
consumer electronics manufactured, the amount of PCBs produced to control them
must be equal in quantity. These high-volume PCBs have low per-unit cost,
keeping the price of the final product relatively small. The challenge is
maintaining the uniformity and quality of these PCBs, which is why PCB
manufacturers have to comply with strict industry standards and quality-control
measures to ensure that every consumer electronic functions as expected.
The applications
of PCBs in consumer electronics are extensive. The following are just a few of
the common uses of PCBs in consumer electronics:
• Mobile Devices: Smartphones and tablets are at the heart of our daily routine, functioning as everything from our alarm clocks to our GPS. None of these processes would be possible without high-volume PCBs.
• Computer
Electronics: Desktops and laptops both contain PCBs at their cores, as do the
screens and peripheral devices associated with them. Just a few computer
components that make use of PCBs include motherboards, flex connectors and
memory interface cards.
• Recording
Devices: Camcorders, digital cameras, microphones and other recording devices
all rely on their internal PCBs to function.
• Entertainment
Systems: Everything in your home entertainment system, from your DVD player and
video-game console to your television and stereo set, contains a mass-produced
PCB at its core.
• Home
Appliances: Almost every modern device runs using electronic components. Alarm
clocks, microwaves and even many refrigerators and coffee makers now run using
PCB-based electronics.
2) Medical Devices
Electronics
contributes significantly to the health-care industry, functioning as
diagnostic, monitoring and treatment devices. The medical applications of these
electronic devices continue to grow as electronics evolves to become more
efficient and dense, leading to endless new possibilities.
However, a small
package is needed to meet the size requirements for an implant or emergency
room monitor. For this reason, medical PCBs tend to be specialty high-density
interconnect PCBs, also referred to as HDI PCBs. Medical PCBs may
also be made with flexible base materials, allowing PCB to flex during use,
which can be essential for both internal and external medical devices.
• Monitors:
Personal and healthcare monitors contain PCBs, including blood glucose
monitors, heart rate and blood pressure monitors, and more.
• Scanning
Technology: CT scanners and ultrasonic technology often use PCB-based
electronics.
• Control
Systems: The equipment controlling fluid infusion, flow rate and dispensation
is electronically controlled.
• Internal
Devices: Heart pacemakers and similar internal medical devices maintain patient
health, run by minuscule PCBs at their centers.
• Scientific
Instrumentation: Medical research uses numerous scientific instruments to study
disease and test patient outcomes. These include electronic microscopes,
photometers and control systems for generators and compressors, among other
things.
3) Industrial electronics
In such a fast
challenging environment, industry standards is equally rigorous.
Currently, thick copperPCBs (significantly thicker than standard ounce PCBs) are often
seen in other applications. This kind of PCB facilitate high-current industrial
applications and battery chargers.
• Industrial Equipment: Many electric drills and presses used in the manufacturing industry operate using PCB-controlled electronics.
• Measuring
Equipment: Equipment used to measure and control pressure, temperature and
other variables in the industrial manufacturing process usually runs using
PCBs.
4) Automotive Applications
Surrounding
Monitors: Newer car models are often designed with substantial safety systems
to help the driver monitor blind spots and more accurately judge distances.
Many cars now come with full-perimeter monitor systems, using radar or cameras
to measure distances and alert the driver to close-proximity objects. These
systems require high-quality PCBs in order to function correctly.
• Control Systems: Car control systems, including engine management systems, fuel regulators and power supplies, use PCB-based electronics to monitor and manage resources. Some control systems even drive the car for the driver in certain situations. For example, some cars on the market today offer automatic parallel-parking functions.
• Navigation
Devices: Incorporated navigation devices are now common in modern vehicles,
using GPS computers to help drivers find their way through unfamiliar territory
or identify the fastest route to their destination.
• Audio and
Video Devices: Many cars on the market today have advanced dashboards that
connect the vehicle to the radio or a passenger's phone or music device.
Additionally, many family vehicles make use of passenger movie screens to
occupy passengers during longer rides. All these devices are controlled using
PCB-based electronics.
5)Aerospace facility
• Monitoring Equipment: Instrumentation, including accelerometers, pressure sensors, microphones and torque and force sensors all use PCBs as part of their basic function. These products are used within the engines and cockpits of airplanes and rockets, both to monitor the function of the vehicle and to communicate with ground control.
• Testing
Equipment: In addition to the function of an aircraft, PCBs are involved in the
development and testing of air vehicles. Testing equipment that collects data
during structural, vibration and flight testing procedures uses PCBs at its
core. This data can then be used to develop more effective, efficient and safer
aircraft.
6)Other
Applications
• Firearm Applications: Both military and civilian gun manufacturers often use PCBs in their testing equipment. Manufacturers will often use such equipment to ensure the safety and functionality of explosives, guns and ammunition before putting these products on the market. Some of the equipment used includes penetration shock recorders and impact testing equipment.
• Marine
Applications: Both underwater and sailing applications are common places to
find PCBs. PCBs often control the navigation, engine management and power
distribution systems used on sailing vessels. The fluctuating amounts of
pressure and vibration result in a variety of considerations designers have to
make to guarantee proper, continuous function.
• Security
Applications: Security systems in and around homes and businesses make use of
PCBs to coordinate the various components and signals used to detect the
presence of an intruder. Smoke, fire and burglar alarms all use PCBs, as do
electronic door locks and motion sensors.
• Broadcasting
and Telecommunications Applications: As stated previously, PCB-based LED
lighting displays are common in the telecommunications and broadcasting
industry. PCBs are applied in a variety of other functions within this industry
as well. High-frequency amplifiers and filtering appliances commonly use PCBs,
as do booster stations, receivers, frequency boards, mixing decks and
microphones.
