What are the reliability test items for PCBA?
PCBA (PCB Assembly) refers to the process of mounting components on a bare PCB board, inserting components and realizing soldering. The circuit boards we usually see are all PCBA boards with components soldered on the basis of PCB. PCB is a “bare board” or “uncoated board&...
Evaluation criteria for post-welding PCB surface cleanliness
Today, when the no-clean process is widely adopted, it is extremely difficult to obtain a very clean post-welding PCB surface. The presence of flux residues on the post-welding PCB surface is inevitable. The problem lies in how to define cleanliness. If the PCBA board surface is visually co...
PCB/PCBA Failure analysis
Generally speaking, the number of failed products is limited, or even there is only one. Therefore, for the analysis of failed products, we must follow the principle of layer-by-layer analysis from outside to inside and from non-destructive to destructive. Avoid destroying the failure site ...
Principle of PCBA strain testing
Utilizing the strain effect of metal conductors, the strain of the PCBA is quantified by the change in resistance value of the strain gauge (strain rosette) attached to the PCBA as it undergoes mechanical deformation along with the deformation of the PCBA. Thus, by comparing this quantified strai...
Why conduct PCBA strain testing?
To adapt to the growing international emphasis on environmental protection, PCBA has been changed from lead-based processes to lead-free processes, and new laminate materials have been applied. These changes will all cause changes in the solder joint performance of PCB electronic produ...
