How to detect counterfeit electronic components during PCBA processing?

A

Counterfeit electronic components pose a significant risk to industries worldwide. These fake parts affect virtually every sector, including medical, automotive, consumer goods, networking, communications, aerospace, and defense.

Q

Introduction to SMT processing and production process

A

1. What is SMT processing and production? SMT processing and production, also known as Surface Mount Technology (SMT), is a new generation of electronic assembly technology developed from hybrid integrated circuit technology. It is characterized by the use of surface mount technology and reflow soldering technology, becoming a new generation of assembly technology in electronic product manufacturing. The main equipment of the SMT production line includes: printing machine, placement machine (mounting surface electronic components), reflow soldering machine, plug-in machine, wave soldering machine, testing and packaging equipment. The widespread application of SMT has promoted the miniaturization and multi-functionalization of electronic products, providing conditions for large-scale production and low defect rates. SMT is surface mount technology, a new generation of electronic assembly technology developed from hybrid integrated circuit technology. II. SMT processing and production process flow 1. Screen printing: Its function is to print solder paste or adhesive on the PCB pads for component soldering. The equipment used is the screen printer (screen printing machine) located at the forefront of the SMT production line. 2. Dispensing: This is to dispense glue to fixed positions on the PCB. Its main function is to fix components on the PCB. The equipment used is a dispensing machine, located at the forefront of the SMT production line or after the testing equipment. 3. Mounting: Its function is to accurately install surface mount components to fixed positions on the PCB. The equipment is a placement machine, located behind the screen printer in the SMT production line. 4. Curing: Its function is to melt the adhesive, so that the surface mount components can be firmly bonded to the PCB. The equipment used is a curing oven, located behind the placement machine in the SMT production line. 5. Reflow soldering: Its function is to melt the solder paste, bonding the surface mount components to the PCB. The equipment used is a reflow soldering oven, located behind the placement machine in the SMT production line. 6. Cleaning: Its function is to remove harmful soldering residues, such as flux, from the assembled PCB. The equipment used is a cleaning machine, whose location is not fixed; it can be online or offline.

Q

How to determine if a PCBA processing plant is reliable?

A

Many clients feel confused when searching for PCBA processing plants; they don't know how to choose a high-quality and reliable processing plant. The circuit board assembly production process is very complex. From the initial discussions to component procurement and SMT processing, problems can easily arise in certain stages, leading to less-than-ideal production results. So how do we choose a reliable PCBA processing plant to cooperate with? How to judge if a PCBA processing plant is reliable? 1. Examine the basic production equipment: A high-quality factory will definitely have professional production equipment. The manufacturer needs very professional equipment during production. At this time, it is necessary to see if the equipment is fully equipped, whether it can independently complete all processing procedures, whether it has fully adopted automated equipment, and whether the machine production process can meet your product requirements, etc., such as high-speed placement machines, multi-temperature zone reflow soldering, AOI detection instruments, ICT online testing instruments, fully automatic printing machines, etc. These are the basics of production.
2. Company environment: The factory's hygiene can directly reflect the factory's production quality. The factory's production environment and production results are not directly related, but the better the production environment, the higher the factory's requirements for the process. Only those who pay attention to the details will be more focused on serving customers and doing a good job on customers' products.
3. Product quotation: The price of SMT patch prototyping is relatively transparent in the industry; some are too high, and some are very low, all kinds of messy things. Tongsen Electronic chooses to purchase original parts from formal channels and strictly controls product quality. Although this increases processing costs, it can guarantee product quality. However, some PCBA processing plants may choose to cut corners and use fake raw materials to reduce prices, resulting in unstable quality. We should choose the most cost-effective manufacturer based on our own situation and not choose small workshops without quality assurance to save money. 4. Service: As the brain of intelligent products, PCBA circuit boards are not just manufactured. As a qualified supplier, pre-sales and after-sales service should also be equally valued. A trustworthy factory has good service awareness, can solve many unnecessary problems for customers during 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.
