What needs to be paid attention during PCBA process?

PCB is an indispensable part for any electronic equipment in small toys or computers., etc. The complex interconnection components include resistor, diode and capacitor, which help components work normally in series. In a sense, it is similar to the “brain” of the system. PCB assembly process must be of no any mistakes. Here are some points that need to be paid attention:

1.Supply chain management: In order to create high quality PCB, the first thing needing consideration is supply chain. For the availability, both quality and price are important, so is delivery time of components.


2.PCB layout. The common question during manufacturing stage is pcb layout in minor differences. Even though various types of designs looks the same to outward seeming, the manufacturing processes are different. You need to ensure PCB layout is feasible during manufacturing process.

3.Test-test has to be conducted after PCB assembly. What needs to be done is to design test point. Some tests include:

Micro-section analysis-also referred to as cross section analysis. This test contributes to identifying components fault and thermal-mechanical faults.


Solderability test. This test contributes to testing reliability of PCB solder pad, to ensure a firm surface and a reliable soldering point. It also contributes to confirming if storage will have an effect on solder components.

PCB pollution test-This can test many issues, such as corrosion and degradation. Scaling powder residue will result in pollution and thereby case components failure. Pollution analysis is famous for its accuracy and preciseness.

Optical microscope-This can test the issues relevant to PCB and soldering as well as overall pcb assembly. The process is famous for its speed, as it involves using high-power microscope to inspect incorrect structure.
