As a new type of stencil-free solder paste application technology, solder paste spray printing has demonstrated significant practical value in the production of military electronic products due to its convenience and flexibility.
As millimeter-wave radar technology finds increasingly widespread application in fields such as autonomous driving, aerospace, and security surveillance, the demand for high-performance printed circuit boards (PCBs) has grown accordingly.
Before a new PCB assembly model enters mass production, it typically requires validation through multiple prototype versions.
With the trend toward smarter and more integrated electronic products, a wide range of BGAs, fine-pitch components, and ultra-small devices are now in widespread use, making SMT technology the mainstream process for electronic assembly.
Solder mask application is a core process in PCB manufacturing that determines yield and reliability, and pre-treatment is the cornerstone of its success.
The primary purpose of pretreatment in each PCB manufacturing process is to achieve two key objectives: cleaning and surface roughening.
Driven by the need to “streamline processes, reduce costs, and minimize pollution,” an increasing number of electronic soldering operations are adopting “no-clean” post-soldering processes.
It is crucial to understand the resistance of PCB traces. This directly affects power supply stability, heat generation, and even signal quality.
SMT is currently one of the most widely used technologies and processes in the electronic assembly industry. Since its introduction to the market in the early 1970s, it has gradually become the mainstream in the modern electronic assembly industry.
Mastering electronic component inspection techniques is a key factor in circuit fault detection, and the final step in circuit fault detection is to confirm whether a component actually has a defect, which requires the use of inspection techniques to achieve.
