There is no denying how commonplace electronic devices are to modern living today. With the internet of things right around the corner, we are set to make electronic devices out of even more everyday appliances. From refrigerators to air conditioning the limits are seemingly endless.
It comes as no surprises then that manufacturers of Printed Circuit Boards are in high demand and picking out the best from the teeming plenty is a necessary investment in time to get the right fit of PCB for innovation.
What is the PCB?
To set the stage for a proper selection of the best PCB manufacturer in China, a basic understanding of what a PCB is and how it is designed is necessary for a firm grasp of the selection process.
The PCB is the base on which electronic circuits are built, but to truly expand on its functionality; it has to go through a series of processes using two major technologies which will be discussed later in this article. This process is what is called the PCBA or Printed Circuit Board + Assembly.
PCB finds use in almost all modern-day electronics – from CT Scanners used in hospitals to televisions; and of course, in computers as graphics cards to the very important motherboard. As earlier noted, the Internet of Things will find electronics being embedded into a wide range of household appliance: cars, wearable health monitors, voice-controlled home automation and many, many more.

SMT vs. THT
A PCB, fully assembled, has all the elements needed to be attached to it and all aspects of the circuitry fully fitted. This process can be accomplished using either the Through Hole Technology (THT), or the Surface Mounted Technology (SMT).
The Through Hole Technology is a process where components are fitted into holes drilled in the PCBs (Through-Hole Vs Surface Mount Assembly). They are connected by attaching them to lead wires. They are considered an older technology and were poised to be phased out with the more modern SMT. However, technology is still useful in components that require reliability.
The Surface Mount Technology, SMT, involves mounting components on the surface of the board and soldering them on. This relatively simple change over the through-hole technology accounts for less use of the board circuit space, ability to use both sides of the board allowing for design complexity. This method allows for devices to be smaller and easier to package.
With this basic understanding of PCBs and PCBAs, we can take a closer look at some manufacturers of PCBs and PCAs in China and after that, we will show you why Ray PCB is our best choice in the manufacturing of PCBAs in China.
Although these are the basic two processes for PCB Assembly. Other technologies, a variation on the basic idea of these two, have also been developed.
In the course of this article, they will be explored and the companies that can handle them x-rayed.
1. Well PCB
They also have colleges trained sales and customer service staff who with their highly skilled knowledge can word with customers to meet their specific needs. They also have the following certifications: ISO14001:2015, ISO9001:2015 Certified; IATF16949: 2016 Certified. They have no minimum orders and a warranty that offers refunds, returns and replacement if any fault is traced back to them.
WellPCB boasts two fully operational and highly computerized factories from where they can service customers all over the globe.
2. ZXHPCB
This is a subsidiary of the Zhongxinhua group. It has over 21years cognate experience in the manufacturing of PCBs. They have actively devoted the last 10years in the research and development of PCBAs. This intentional focus has seen ZXHPCB lead the way to be in 2-layers PCB, 3-layers and even multiple double side PCBAs.
With well-established proficiency in Computer-Aided Manufacturing, CAM, PCB boasts a 99.5% soldering yield.
Fully IPC certified, its three factories can handle high volume production with ease. They also run one of the most robust quality assurance checks during all stages of the production process with strict complains to the strategies of the PCBA cycle. The Plan, Do, Check and Act is a top-level quality assurance process.
Along with offering Single, Double and Multi-Layer PCB, they also manufacture Aluminium PCB. The unique design of aluminium is that the circuit board is aluminium based rather than plastic or epoxy resin.
The unique advantage of aluminium PCBA is that it draws heat away from the parts of the PCBs. Some designs rely heavily on LEDs, and that can cause heat build-up on the circuitry of a PCB.
With an aluminium-based PCB, the ability to draw heat away means that it can go for longer without having high temperatures that can damage the board.
For appliances that are LED heavy, an aluminium board is usually the best option and ZXHPCB is one of few that can deliver on aluminium based PCBA.

Frequently Asked Questions
1. How Many Layers Can A PCB Have?
Printed Circuit Boards (PCBs) have 100 layers. With each layer comes increased functionality. Most devices can effectively be handled by 4 to 8 layers, but 100 layers can be executed.
2. Why are PCBs Green in Colour?
The unique green colour of a PCB comes from the solder mask which protects copper circuits on the fibreglass substrate. It helps to prevent short circuits and soldering errors. The colour of the mask gives the board a green colour.
3. How Long Does It Take To Manufacture A PCB?
It can take anything between 3 – 14 business days to manufacture depending n the complexity of the design. A well-run manufacturing company will give appropriate estimates with complexity in mind.
4. What Causes A PCB To Fail?
Most PCB failures can be linked to design. It always best to choose a manufacturing company (like RayMing Technology) that can design and exhaustively check a prototype before sending it off to mass production.
5. Can A PCB Board Be Repaired?
Depending on the cause of the damage there are PCB boards that can be fixed by re-soldering and the use of adhesive glues. However, before dealing with any manufacturing company check for the details of most warranty as most in-house manufacturing defects should be covered by the warranty. If needed, it is best to take a PCB to a specialist trained in repairs.
