Rogers Keyboard Turnkey PCB Assembly Custom Aluminium Printed Circuit Board
PCB Application - Multilayer Board
Multi-layer board: The required circuits are made on the front and
back surfaces of multiple double-sided boards, and an insulating
layer (Prepreg) is sandwiched between the two double-sided boards
and then pressed together to form several layers of copper. The
construction of the wire is usually an even number of layers due to
the use of multiple double-sided laminates. The number of copper
wires that can be made by multi-layer boards is the largest, and it
is used in more complex circuits. At present, the motherboards used
in computers mostly use eight-layer boards because of too many
components. Generally, small electronic products, such as mobile
phones, tablet computers, etc. Due to the requirement of small
size, at least an eight-layer board is required. The more
electronic components, the smaller the product size, and usually
more layers of turnkey PCB assembly prototype service are required.
1. Material
FR-4 (glass fiber epoxy resin substrate) is the most widely used
material in the global electronics industry. FR is a code name for
a flame-resistant material grade, which means a material
specification that the resin material must be able to
self-extinguish after burning. It is not a material name, but a
material grade, so there are many types of FR-4 grade materials
currently used in general circuit boards, but most of them are
four-functional epoxy resin plus filler (Filler) and glass fiber.
The composite material made. In recent years, due to the
development of electronic product installation technology and
turnkey PCB assembly technology, FR-4 products with high Tg have
appeared again. Tg degree (glass transition temperature - Glass
Transition Temperature)
Example: ISOLA FR402, FR408, 370HR South Asia NP-140, NP-155, NP-175

Medical equipment
Electronics make a major contribution to health - the nursing
industry, as diagnostic, monitoring and therapeutic equipment. As
the development of electronics becomes more efficient and dense,
the medical applications of these electronic devices continue to
grow, leading to endless new possibilities.
At the heart of these medical devices is the turnkey PCB assembly.
PCBs in the medical industry are highly specialized to accommodate
the unique constraints of medical devices. In many medical
applications, small packages are required to meet the size
requirements for implants or emergency room monitors. Therefore,
medical PCBs tend to be specialty high-density interconnect PCBs,
also known as HDI PCBs. Medical PCBs can also be made with flexible
substrates that allow the PCB to bend during use, which is
essential for both internal and external medical devices.
Medical PCBs are held to a higher standard than most other PCB
types due to the health concerns associated with them. In addition
to complying with strict medical regulations, repeatability and
reliability are two essential qualities that medical PCB suppliers
must achieve.
Medical PCB applications are growing as fast as the medical device
industry itself. Some of the most common medical PCB applications
include:
1. Monitors: Personal and healthcare monitors, including blood
glucose monitors, heart rate and blood pressure monitors, and more.
2. Scanning Technology: CT scanners and ultrasound technology
typically use PCB-based electronics.
3. Control System: The device controls the infusion, flow rate and
distribution are electronically controlled.
4. Internal Devices: Pacemakers and similar internal medical
devices keep patients healthy and are operated by a central
micro-PCB.
