Three Shenzhen PCBA companies with matching price and quality

ponedjeljak , 06.02.2023.

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. This company has a strong service concept and management concept, and uses modern management methods to manage the employees in the assembly workshop. Compared with other PCBA processing factories of the same type, FS Technology mainly focuses on service quality.

In order to ensure the PCBA quality that satisfies customers, FS Technology strictly implements IPC PCB standards and unswervingly completes customer orders. They are responsible for all projects, whether series or prototype. It is hard for you to imagine that a PCBA manufacturer can set up manual inspections in every link of production and assembly. These personnel responsible for inspections have many years of experience in PCBA production and are rare talents. In addition to manual inspection, they have advanced PCB assembly testing equipment such as XRAY, AOI inspection, etc.

Excellent services available:

High Speed SMT Service
Fully automatic DIP assembly service
Design and modify circuit layout
Comprehensive PCB Manufacturing Services

PCBMay

PCBMay is a PCB manufacturer located in Guangming District, Shenzhen. The company's main business is the manufacture of advanced PCB boards, including high-density interconnect PCBs and multi-layer circuit boards with 1-50 layers. Compared with other companies, this company can provide services that match the price, that is, it is expensive but worth it.

While they specialize in PCB fabrication projects, electronic assembly jobs are also catered for. The company can provide SMT assembly services and cooperate with a large number of advanced PCBA processing plants. These processing plants have as many as 35 SMT assembly lines, which can complete a large number of orders in the shortest time.

China PCB One

ChinaPCBOne is located in Bao'an District, China. The company provides one-stop PCB services including - Multi-Layer PCB Fabrication, Turnkey PCB Assembly Services, PCB Prototyping, Small and Medium Volume Production, PCB Design, Component Sourcing, etc. Official website

PCB Repair Tips - FS Technology

petak , 17.06.2022.

Many people do not know much about the maintenance of circuit boards. Next, FS Technology will explain the maintenance skills of PCBs.
1. Observation method
When we receive an FS Tech PCB for repair, we first take a closer look at what it looks like. If the PCB is burnt, please confirm that the power supply PCB is normal before turning on the PCB, and then turn it on again to ensure that no secondary damage will be caused. The observation method is a static verification method, when using the observation method, the following steps are usually followed.

Step 1: Check whether the PCB is artificially damaged;

Step 2: Check whether the PCB components are burned out;

Step 3: Test the integrated circuits in the PCB;

Step 4: Check the chain for loose, burnt or damaged caterpillars. It is a copper hole that sinks from the platform;

Step 5: Check the fuses (including fuses and thermistors) in the FS Tech PCB to make sure the fuses are not blown. Sometimes the fuse is too thin to see, and auxiliary equipment such as a multimeter can be used to determine whether the fuse is damaged.

2. Fixed measurement method
For most printed circuit boards, previous methods of observation do not detect problems. Although a small number of PCBs may be physically deformed for some reason, the cause of the failure is not difficult to determine. point on the graph. Methods of measuring, identifying and solving problems.

Before measuring, first determine whether the circuit is controlled by an analog or digital signal. The following are just standard methods for measuring digital circuits, and management basically follows the steps below.

Step 1: Use a multimeter to check whether there is a short circuit between the power supply and the ground;

Step 2: Measure the diode with a multimeter and check that it is working properly;

Step 3: Use a resistance multimeter to measure the capacitance to see if it is a short circuit or an open circuit. If there is, it means that there is a problem with this part of the FS technology circuit. The unit or circuit associated with it. ;

Step 4: Measure integrated circuits, transistors, resistors, etc. with a multimeter. In the PCB, see if they match their own logic characteristics

Circuit board maintenance skills

Tips and Warnings Most PCB management issues can be resolved by reviewing both observational and static measurement methods. Remember that the power supply must be normal, so as not to damage the secondary circuit after the next step.

3. Network measurement method
The Internet measurement method is commonly used by manufacturers who produce PCBs in series. . Internet measurement methods basically solve two problems. The first is to isolate the problems found in the first two steps, and finally the problematic components are eliminated. Second, in the above two-stage test, the problem is not resolved, so the cause of the failure must be determined through Internet measurements. The Internet measurement method is mainly used to compare two good and bad PCBs, through which problems can be found and solved.
