Bridge rectifiers are well-known electronic devices that are widely applied in various kinds of electronic circuits to convert AC (Alternating Current) to DC (Direct Current). Previously TECHDesign has introduced the basic concept, working principle, types, and applications of bridge rectifiers in “4 Things You Need to Know about Bridge Rectifier”. In this article, we will be discussing the advantages of ABS bridge rectifiers produced by the world-leading supplier PANJIT.
PANJIT Provides the Best Features of Bridge Rectifiers
Before introducing ABS bridge rectifiers, we can have a look at the bridge rectifiers provided by PANJIT. PANJIT provides only halogen-free compound bridge rectifiers with gull-wing leads and matte tin plating to standardize the bridge rectifier products. Compared to flat leads, gull-wing leads can increase the touched area between the bridge rectifier and the PCB, and ensure the rectifier conducts well and functions normally. And for matte tin plating, the solderability and reliability of it are better than those of bright tin plating as it is made of the tin without other brighteners added in.
Automated Manufacturing Processes Ensure Outstanding Reliability
Other than those, PANJIT uses upgraded and automated manufacturing processes to enhance the reliability of its bridge rectifiers. It is worth mentioning that instead of solder dispensing, solder printing is used to bond a die on a substrate. By printing the solder evenly and plainly on the substrate, this method can well control the adhesive quality and effectively avoid solder voids. Besides, an automated pick and place machine is applied for die attachment. Different from using a manual die machine to select and attach dies on the substrate, the machine can pick and place the dies automatically to completely avoid micro-cracks, die shift, and die rotation. It raises the adhesive accuracy and yield rate.
The important steps mentioned above determine the reliability of bridge rectifiers. For instance, the solder void rate of PANJIT’s bridge rectifiers is less than 10%, and their reliability can reach as high as 1000 hours. Compared to the general 30% void rate and 168/500-hour reliability standards in the market, PANJIT has ensured the highest quality of its bridge rectifier products with smart manufacturing implementation.
