The difference between the inner and outer layers of PCB
There are differences in position, function, manufacturing, and cost between the inner and outer layers of PCB. The inner layer is responsible for electrical connections, which is complex and costly to manufacture; The outer layer is connected to the outside world, with simple manufacturing and low cost, but it needs to consider aesthetics and wear resistance.
Why is it necessary to bake the PCB board before SMT mounting?
baking PCBs is to ensure that components can be reliably soldered to the PCB surface during SMT surface mount processing, improving product quality and reliability.
The details of SMT processing cannot be ignored
In the field of SMT processing, details determine success or failure. From material selection to environmental control, from equipment calibration to process optimization, to strict quality inspection, every step needs to be carefully planned and executed.
How to apply three proof paint on PCB?
PCB coating with three proof paint can protect PCBs from harsh environmental erosion and extend the lifespan of electronic products,Its main function is to form a transparent protective film on the surface of the PCB, preventing external factors such as moisture, salt spray.
The key role of steel mesh in SMT process
In SMT technology, the stencil is a seemingly simple yet extremely critical component. It is a thin metal plate with holes precisely etched on it according to the PCB design, corresponding to the component pads.
Application of lead free technology in PCBA processing
Lead free technology refers to the use of lead-free solder for soldering during PCBA processing, replacing traditional lead containing solder. This change is mainly driven by environmental regulations
Burning process in PCBA processing
burning refers to writing pre written program code into the memory on the PCBA board. This process enables the device to work according to the requirements of the program and achieve the expected functions.
Detailed explanation of PCB surface mount processing technology from SMT to BGA

Why do we need to clean PCBA after processing
Cleaning is crucial in PCBA OEM material processing, as it can remove surface dirt and residues, enhance insulation performance, improve corrosion resistance and appearance quality。
How long is the SMT production cycle?
The SMT production cycle refers to the time required for the entire process from customer order placement to product completion and delivery. This pro
The basic process of PCB surface mount processing
The basic process of PCB surface mount processing includes preliminary preparation, material preparation and inspection, SMT surface mount processing, reflow soldering, and quality inspection and assembly.
How to control the welding quality in SMT surface mount processing?
By optimizing welding parameters, controlling welding environment, improving equipment accuracy and stability, strict material management, strengthening employee training and management, implementing strict quality inspections, and optimizing production processes, we can effectively improve the welding quality of SMT surface mount processing.
