PCB Manufacturability Design And PCBA Manufacturability Design

PCBA manufacturability design and PCB manufacturability design, it looks like only one “A” difference, in fact, there is A big difference, PCBA manufacturability design includes PCB manufacturability design and PCBA assembly design (or assembly design) two parts.

 

PCB manufacturability design

Raw material selection, stack-up structure design, hole ring design, solder mask design, surface treatment, panel design

PCB manufacturing process

Manufacture method and capability of PCB, packaging of PCBA, welding process (heat resistance), panel separation method

 

PCBA manufacturability design

Package selection, pad design, assembly design, process path design, component layout design, component spacing design

Need to match the manufacturing process

Welding process, solder paste application, steel mesh design, mask selection welding tray design, panel separation method

 

 

PCB manufacturability design focuses on “manufacturability”, including plate selection, compaction structure, hole ring design, solder resistance design, surface treatment and plate-making design.

All these designs are related to the processing capacity of PCB. Restricted by the processing method and capacity, the minimum line width and line distance, the minimum aperture, the minimum pad ring width and the minimum welding resistance gap must conform to the processing capacity of PCB, and the designed lamination and compaction structure must conform to the processing technology of PCB.

Therefore, the key point of PCB manufacturability design lies in meeting the process capacity of PCB factory. Understanding the manufacturing method, process flow and process capacity of PCB is the basis of implementing process design.

 

PCBA manufacturability design focuses on “assemblability”, that is, to establish a stable and solid process, to achieve high quality, high efficiency and low cost of welding.

The design includes package selection, pad design, assembly design, component layout, steel mesh design and so on.

All these design requirements are around higher welding yield, higher manufacturing efficiency, lower manufacturing cost to launch.

Therefore, it is very important to understand the process characteristics of all kinds of packaging, common welding defects and influencing factors.

 

PCB manufacturability design or PCBA manufacturability design, can’t simply design elements around the individual to carry out, such as components selection, 0201 is the most commonly used packaging for mobile phone board, and the communication board is not, in the design must be comprehensive and systematic survey technology of veneer, also is the strength of the design concept of “integration” again and again.
