PCB manufacturability design and PCBA assembly design

(Summary description)We know that although PCB and PCBA seem to differ by only one letter "A", there is a big difference. PCBA manufacturability design includes two parts: PCB manufacturability design and PCBA assembly (assembly) design. Let’s take a look at the following Sanjing:
PCB manufacturability design: more emphasis on "manufacturability", the design content mainly includes: plate selection, press-fit structure design, ring design, solder mask design, surface treatment and imposition design, etc., these designs are in line with PCB It is related to the processing capacity and is limited by the processing method and capacity. The designed minimum line width and line spacing, minimum aperture, minimum pad ring width, minimum solder mask gap, etc. must meet the processing capabilities of the PCB. At the same time, the designed laminate and laminated structure...

We know that although PCB and PCBA seem to differ by only one letter "A", there is a big difference. PCBA manufacturability design includes two parts: PCB manufacturability design and PCBA assembly (assembly) design. Let’s take a look at the following Sanjing:

 

PCB manufacturability design: more emphasis on "manufacturability", the design content mainly includes: plate selection, press-fit structure design, ring design, solder mask design, surface treatment and imposition design, etc., these designs are in line with PCB It is related to the processing capacity and is limited by the processing method and capacity. The designed minimum line width and line spacing, minimum aperture, minimum pad ring width, minimum solder mask gap, etc. must meet the processing capabilities of the PCB. At the same time, the designed laminate and laminated structure must comply with the PCB processing technology. Therefore, the focus of PCB manufacturability design is to meet the process capability of the PCB factory. Understanding the manufacturing method, process flow and process capability of the PCB is the basis for the implementation of process design.

 

 

The PCBA manufacturability design focuses on "assemblyability", that is, to establish a stable and robust processability to achieve high-quality, high-efficiency, and low-cost soldering. The content of the design includes: package selection, pad design, assembly method design, process path design, component layout, stencil design, etc. All these design requirements require higher soldering yield and manufacturing efficiency, as well as lower manufacturing costs. Therefore, it is very important to understand the process characteristics, common soldering defects and influencing factors of various packages.

 

Finally, whether it is PCB manufacturability design or PCBA manufacturability design, it cannot simply be carried out around individual design elements, such as component selection. When designing, we must comprehensively and systematically consider the manufacturability of the veneer, that is, the "integrated" design concept.

 

The above is about PCB manufacturability design and PCBA manufacturability design, I hope it can be helpful to everyone!
