Perhaps the era of China"s PCBA industry has finally arrived. As we all know, in the PCB field, the United States is actually the first to develop PCBA business, and they almost occupy the global high-end PCB manufacturing and assembly market. With the rise of China"s manufacturing industry, electronic products made in China are leading the world. According to the report of Central Finance and Economics, since 2014, China"s PCBA industry has been developing rapidly, and now it has occupied 50% of the global market. In this article, we will introduce the list of PCB manufacturers in China. These companies are all PCBA processing factories with matching price and quality.

FS Technology

For electronics manufacturers who are familiar with the Chinese market, I believe you must know FS Technology, which is a skilled PCBA company. Since the establishment of a special economic zone in 1974, Shenzhen"s foreign trade has increased rapidly. FS Technology was established in 2000. Due to its skilled assembly technology and advanced management concepts, FS Technology has been supported by the Shenzhen government and has become a leading enterprise in Shenzhen PCBA.

Why choose FS Technology? You can get the answer to this question from their website fs-pcba.com.

I believe that customers who need to purchase turnkey PCBA services know that circuit boards need to be inspected before mass production. We need to understand the product quality when we come out, and we can obtain quality assurance before PCBA prototype manufacturing. FS Technology believes that this is a necessary link, and the customer and the turnkey company discuss details and specific parameters before proceeding with production, and pass prototype testing to lay the foundation for further production. Let"s take a look at the importance of this step.

Prototyping facilitates screening of manufacturers" capabilities

A PCBA prototype can give you a clear idea of the strength of a manufacturer, especially for a manufacturer that the two parties have not worked with before. We all know that merchants must have exaggerated descriptions of goods, and the description of their own capabilities by circuit board manufacturers is the same. Therefore, we need to judge its capabilities before choosing a suitable PCBA company, rather than relying on words to understand. In order to eliminate the information difference between the manufacturer and the customer, PCBA prototype proofing provides fairness for this. You can truly understand its strength through the PCBA board samples sent by the manufacturer, so as to determine whether to establish a long-term cooperative relationship.

PCBA Prototypes Reduce Error Rates in Mass Production

The more high-quality circuit board manufacturers, the greater the processing and manufacturing pressure. A quality turnkey PCBA company must have no shortage of customers, that is, their factories are working almost 24 hours a day. A large number of orders and long work are the main reasons for PCBA defects. After all, PCBA processing needs to go through a series of complex processes. It is impossible for us to ensure that every board is correct, but we will carry out strict PCBA quality control to ensure that every process or processing step is error-free. After the circuit board has been manufactured, we can provide you with a complete PCBA test service. FS Technology has 7 fully automatic SMT assembly equipment, and the monthly order amount received exceeds 10 million US dollars. We need to balance quality and quantity. For this reason, we suggest that customers who cooperate with FS Technology for the first time must choose to purchase prototype assembly services, which will lay the foundation for our follow-up cooperation and promote our cooperation.

Testing PCBA samples lays the groundwork for future batch processing.

The purpose of PCBA testing is to understand the performance and operational response of a new product. The functionally tested samples will lay a good foundation for future mass production. Calculation of appropriate material costs can pre-optimize quality defects, all of which must be demonstrated in advance. Efficient reference handling minimizes unexpected problems during mass production.

Prototyping PCBs prior to production is critical, as this seems to be the first step in a successful partnership with a recycler. Therefore, for protectors, one needs to select an available PCB manufacturer and provide the manufacturer with the amount or quantity of material required to process the circuit board. After the two parties communicate and negotiate, a formal PCB board inspection is required to lay a good foundation for the next step to strengthen cooperation between the two parties.

FS Technology focuses on PCBA assembly and manufacturing. In terms of PCB, we can produce single-sided, double-sided, multi-layer boards, high-precision and high-frequency high-speed PCBs, etc. The professional production technical team provides you with the guarantee of quality, delivery time and technology. In terms of quality, we share PCB component suppliers with the world"s top 500 companies; in terms of delivery, FS Technology uses the ERP system to carry out detailed production planning, and can always pay attention to the trend of each production process to ensure product delivery; Technically, our production personnel have undergone strict training and assessment to ensure product quality. Therefore, when you choose us, you will get a different service and product quality experience.

PCB wiring is a key factor in ESD protection, FS Technology believes that a reasonable PCB design can reduce unnecessary costs caused by fault inspection and rework. In PCB design, it is more important to overcome the electromagnetic interference (EMI) electromagnetic field effect generated by the discharge current, because the transient voltage suppression stopper (TVS) diode is used to suppress the direct charge injection caused by the ESD discharge.

This article will provide optimized ESD protection for PCB design criteria.

1. Circuit loop.

When current enters circuit loops by induction, these loops are closed and have variable magnetic flux. The current range is proportional to the area of ??the ring. Larger loops contain more magnetic flux and therefore have stronger current induction in the circuit. Therefore, the loop area must be reduced. The most common loop consists of power and ground wires.

Multilayer PCB designs employ power and ground planes, where possible. Multilayer circuit boards not only minimize the circuit area between power and ground, but also reduce the high-frequency EMI electromagnetic fields generated by ESD pulses. If multilayer boards were not possible, FS Technology would have to connect the circuits for the power and ground lines into a grid. The grid connection can play the role of power and ground, and the printed lines of each layer should pass through holes and the connection interval in each direction should be within 6 cm. In addition, when wiring, the power and ground printed lines produced by FS Technology are as close as possible, which can also reduce the loop area.

Another way to reduce loop area and induced current is to reduce parallel paths between interconnects. When a signal cable longer than 30 cm must be used, a protective wire can be used. A better approach is to place the ground near the signal lines. The signal line should be within 13mm of the protection line or grounding line. Arrange long signal wires (>30cm) or power wires and their ground wires of each sensitive element in a crossover. Crossovers must be separated from top to bottom or left to right.

2. The length of the circuit connection.

Long signal lines can also be used as antennas for receiving ESD pulse energy. Trying to use short signal lines can reduce the efficiency of antennas receiving ESD electromagnetic fields. In order to reduce the printed line length of the interconnection, FS Technology will try to place the interconnection equipment in the adjacent position.

3. Inject the ground charge.

Direct discharge of ESD to the ground plane can damage sensitive circuits. Use one or more high frequency bypass capacitors between the power and ground of the consumables. Bypass capacitors reduce charge injection and maintain the voltage difference between the power and ground ports. The TVS shunts the induced current, maintaining the potential difference of the TVS clamping voltage. To reduce parasitic inductive effects, TVS and capacitors should be placed as close as possible to the protected IC.

The one-stop service for PCBA circuit board assembly is the good news for customers, that is, customers package their own requirements for circuit board assembly, hand over all the materials to FS Technology, and FS Technology directly assembles the finished product and sends it to the customer, including "assembly and detection". Customers only need to accept the goods after receiving the goods.

What exactly does FS Technology"s one-stop service include?

FS Technology"s one-stop PCBA assembly service includes PCB design, PCB proofing, PCBA processing (including SMT, DIP), connector crimping, BGA soldering, rework, reballing, PCBA testing,turnkey printed circuit board assembly, packaging and delivery.

FS Technology is customer-centric and thinks about PCBA services from the perspective of customers. Customers only need to put forward requirements, solutions and final product sales. It is the principle of FS Technology to let customers devote themselves to the research and development and sales of new products, and save a lot of time, energy and production costs for customers.

Different from traditional circuit board manufacturing

According to the traditional method, due to the insufficient ability of electronic product manufacturers, they often find professional PCB manufacturers to make circuit boards, and DIP or SMT manufacturers to make patches, and finally assemble, test and sell the products themselves after acceptance. This traditional approach will cost customers more money and time.

FS Technology"s circuit board assembly service provides customers with a total PCBA manufacturing solution service. We can shorten production cycles while reducing overhead. Through PCB circuit board manufacturing, SMT processing, electronic component procurement and other processes, the comprehensive cost of personnel, warehousing, logistics, etc. is truly reduced, and the risks and cycles of the supply chain are greatly shortened and reduced.
