The production of PCBs from the initial prototyping phase to the final fault-free product is difficult. It is difficult to assess the reliability of a good PCB designer. There are a number of quality PCB production organizations in China. And it is a challenging task to select the appropriate one.
China is one of the leading countries in the world when it comes to the manufacturing of good quality PCBs. It is estimated that the Chinese PCB manufacturing market will earn around 19.6 billion dollars by 2027, along with a 5.7 percent CAGR. The main reason for this anticipation is the continuous advancement in technology with time. China has excellent PCB manufacturing technologies.
They can produce several different types of PCBs ranging from simple ones to the most complex designs. The majority of organizations in the world prefer to make contracts with Chinese PCB manufacturers. But the problem arises in the selection of the most reliable PCB maker. Because the increased number of PCB suppliers also reduces productivity.
This article will solve your problem and highlights the top ten PCB manufacturers in China. Besides this, it also highlights the common traits that a good PCB supplier must possess.
Features of Printed Circuit Board Assembly Companies
1. Effective Communication
Good communication acts as a lock opener for new organizational commitments and contracts. For effective communication, it is preferable to contact the PCB producer who speaks the same language as you. It makes sure that you can explain everything to them easily and thus can expect a good quality job. Besides this, good internal communication helps in speeding up the task and getting the desired results.
2. Quality Assurance
Reliability plays a vital role irrespective of the domain you are working in. Reliable PCB producers do not make any compromise over providing good quality services. The PCBs throughout their manufacturing phase, pass through rigorous QC procedures.
It ensures that the developed products comply with the industrial requirements and also different standards like ROHS, IPC, UL, and ISO. In addition to providing quality products, a warranty of around 2 to 3 years along with the repairing services is provided.
3. Experienced and Professional
When you work with a professionally printed circuit board maker, you should not worry about your PCB’s development. A good PCB manufacturer has a team of highly qualified engineers. They make sure that the product under development fulfills the customer’s needs and also provide suitable solutions.
The technical and production experience of the engineers helps them to evaluate the product during each phase of manufacturing. They also understand the possible problems that the customers may face in the future. And provide their solutions well in advance with the product development.
4. Complete Supplier Network
With the sufficient experience gained by the PCB manufacturers in the past years. They have developed an extensive supply chain strategy. They have contacts with raw material providers who also have good qualifications.
As a result, they make sure to produce excellent quality products. Good PCB manufacturing firms provide their customers with the best they can deliver. Also, they have several different channels to get raw materials and components of superior quality at affordable prices.
Types of PCB Assembly process
· Automated PCBA
Many organizations deliver their services in electronic fabrication work. PCBA is one example. In this technique, an expensive system uses automatic machinery to perform the operations. The machinery may include robots that perform the operation of picking and placing the components. Besides this, the soldering machines can also help in increasing the efficiency of the procedure. The fabrication of PCB with the use of automated technology helps in saving effort and time. It is especially useful in the case of bulk PCB manufacturing. The following factors may be the reason for the increased cost:
- Reflow soldering procedure
- Solder paste printing
- Soldering flux cleaning
- Quality Control inspections
- Labor charges
- Solder joints
- Manual soldering method
- Making of a solder stencil
- Surface Mount Components machine programming for place and pick.
These are some of the factors that increase the price of this automated system. But it is preferable to use this technology if there is a need for bulk PCB fabrication. The procedure is also very speedy. The price of automated surface mount technology parts fabrication is directly linked with the BOM lines. The type and size of the electronic parts are other factors that contribute to the increased price. For instance, QFN and BGA will result in increasing PCB fabrication costs. 0201 capacitors and resistor packaging also increase fabrication costs.
The double-sided PCBs have an even higher cost than the single-sided ones because the elements are placed on both sides.
· Manual PCBA
Desoldering and hand soldering process are the steps you use during manual PCB fabrication. This method is suitable when the order is not in bulk and you only need a few prototyping circuits. Since you place electronic parts by hand, there is no need for the CAD file. The CAD file is only needed when there is an automatic placing of the electronic parts. You can use a hot air gun and a soldering sucker to remove the solder and move the components out of the PCB. The desoldering is an additional benefit in the manual fabrication process. In addition to this, it is also advantageous in the repairing services. The QFN and BGA parts soldering is also possible by manually way. It ensures good quality work.

Factors to Consider While Choosing a PCB Manufacturing Company
Quality factor and accountability are important factors to consider for a good PCB manufacturing company. But these are not the only factors. Below are some other important factors that are considered when deciding on the PCB manufacturing service firm:
· Expertise
Before selecting the PCB production company, it is necessary to know what range of services they offer. For example, to verify whether they can fabricate rigid, flex, or flex-rigid circuits. In some cases, you may need to know if they provide a turnkey feature. Single or multi-layered PCBs can be another question to ask before selecting a firm. In addition to this, you should also make sure that they have sufficient material options for PCB. Just try to learn as much as you can about their clients. The greater the number of clients, the more skillful staff they will have. Also, ensure that they are free to work with the medical, aerospace, or communication industries.
· 2. Service Capabilities
Project management also plays a vital role in the successful operation of organizations. Try to learn the policies related to shipping, warehousing, or inventory management. An organization that serves its clients with a number of services deserves to get most of the good clients. And you will also be able to get a good quality product.
· 3. Quality Control
The in-house layout and fabrication process with adequate quality control is necessary. It provides clients with a surety that their products are in safe hands. The QC also helps in improving the shipping times. Besides this, it also verifies that the firm should make quality tests before packaging. The use of the latest technology and machinery is also important.
· Layout Review
The review of the layout is another important factor to get considered. It is always a good idea to check the layout design before the manufacturing phase. It helps in avoiding problems in later stages. Also, it becomes a very stressful and costly event to remake the layout. Therefore, you should carefully look for this aspect in an organization.
· Flexibility & Responsiveness
To what extent is your selected organization flexible? Are they willing to make quick changes or modifications? These are some of the questions that you should ask the firm before starting a contract with them.
