Counterfeit electronic components pose a huge risk to industries around the world. These counterfeit parts affect nearly every industry, including medical, automotive, consumer goods, networking, communications, aerospace and defense.

During the Pcba processing , these components may be overlooked, which will increase the failure, scrap and rework rate involving the pcba circuit board. It has an impact on the overall profitability and value-at-risk of smt chip processors, and has serious consequences in high-reliability applications, especially in the medical and automotive industries. Therefore, it is critical that these components pass some industry-specific tests to identify counterfeit electronic components before smt processing, DIP insertion. Both manufacturers and suppliers have published many specifications and guidelines to establish and maintain product traceability. As long as these practices are adhered to, the use of counterfeit electronic components can be eliminated in the production process, ensuring that the products are authentic electronic components. Tongsen Electronics guarantees that it does not purchase counterfeit components, does not use counterfeit components, and does not recommend the three principles of unknown channels.

What are counterfeit electronic components?
Counterfeit electronic components are counterfeit, non-genuine parts that have been misrepresented in their origin or quality. Counterfeiting involves passing low-quality parts as high-quality parts by changing part numbers, repackaging, or mixing with better-quality parts.

Typical counterfeit electronic components:
1. Unapproved source.
2. Manufactured by an unauthorized contractor not OCM (Original Component Manufacturer).
3. Violation of the original OCM design, model and performance specifications.
4. Whether substandard items are sold as new products.
5. There are incorrect files.

1. What is smt processing and production?
 

Smt processing production, also known as surface assembly technology (SUrfaceMountechnology for short SMT), is a new generation of electronic assembly technology developed from hybrid integrated circuit technology. It is characterized by the use of component surface mount technology and reflow soldering technology. Next-generation assembly technology. The main equipment of smt production line are: printing machine, placement machine (electronic components on the upper surface), reflow soldering, plug-in, wave furnace, test packaging. The wide application of SMT has promoted the miniaturization and multi-functionalization of electronic products, and provided conditions for mass production and low defect rate. smt is surface assembly technology, which is a new generation of electronic assembly technology developed from hybrid integrated circuit technology.

machine). 

2. Dispensing: It is to drip the glue into the fixed position of the PCB, and its main function is to fix the components on the PCB. The equipment used is a glue dispenser, which is located at the front end of the smt production line or at the back of the inspection equipment.

3. Mounting: Its function is to precisely mount the surface mount components to the fixed position of the PCB. The equipment is a pick and place machine, which is located behind the screen printing machine in the smt production line.

4. Curing: Its function is to melt the patch glue, so that the surface-mounted components can be firmly adhered to the PCB board. The equipment used is a curing oven, which is located behind the placement machine in the smt production line.

5. Reflow soldering: Its function is to melt the solder paste to make the surface mount components stick to the PCB board. The equipment used is a reflow oven, located behind the placement machine in the smt line.

6. Cleaning: Its function is to remove the welding residues such as flux that are harmful to the human body on the assembled PCB board. The equipment used is a washing machine, the location is not fixed, it can be online or not.

Many customers are often confused when looking for a PCBA processing factory . They do not know how to choose a high-quality, safe and secure processing factory. The circuit board assembly production process is very complicated. From the initial conversation between the two parties to the procurement of components, to SMT processing, it is easy to have problems in some links, resulting in unsatisfactory production results. So how do we choose a reliable pcba processing factory for cooperation?

1. Look at the basic production equipment: high-quality factories must have professional production equipment, and manufacturers need very professional equipment when producing. At this time, it is necessary to see whether the equipment is complete, whether it can complete all the processing procedures independently, whether it fully adopts automatic equipment, and whether the machine production process can meet your product requirements, etc., such as high-speed placement machine, multi-temperature zone Reflow soldering, AOI tester, ICT online tester, automatic printing machine, etc. These are the basis of production.

2. Enterprise environment: The environmental sanitation of the factory can directly reflect the production quality of the factory. There is no direct relationship between the production environment of the factory and the production results, but the better the production environment, the higher the requirements of the factory for the process, and only the details are done. The most meticulous people will focus more on serving customers and making their products well.

3. Product quotation: The price of smt patch proofing is relatively transparent in the industry, some are too high, some are very low, all kinds of mess. Like Tongsen Electronics chooses to purchase original parts from formal channels and strictly controls product quality. Although the processing cost is increased, the product quality can be guaranteed. However, some pcba processing manufacturers may choose to cut corners and use fake raw materials to reduce prices, so that the quality is unstable. We should choose the most cost-effective manufacturer according to our own situation, and don't choose a small workshop without quality assurance because of cheapness.

4. Service: As the brain of intelligent products, PCBA circuit board is not only required to be manufactured. As a qualified supplier, pre-sales and after-sales work should also be paid attention to. A trustworthy factory with a good sense of service can solve many unnecessary troubles for customers in the manufacturing process, provide reliable after-sales support, and respond quickly to customers, thus ensuring the smooth progress of production. We can choose a more suitable supplier by understanding the company's corporate culture and the factory's attitude towards customers.
