Product introduction<\/strong>
\nShort for Quad Flat no-lead Package; Short for Dual Flat No-Lead, bilateral Flat pin less package, DFN is designed and applied similarly to QFN. The main difference between DFN and QFN is that the pins only line up on either side of the underside of the product rather than around<\/p>\n

Product features<\/strong>
\nSuitable for surface mount packages, halogen-free packages with multiple electrode contacts and a chip pad for mechanical and thermal integrity exposure. The pin less pad design allows it to occupy a smaller PCB area. Considering cost and volume, QFN and DFN package will be a growth area in the coming years, and the prospects are optimistic.<\/p>\n

Application<\/strong>
\nQFN and DFN are considered to be among the most mature industry packaging standards. QFN and DFN are commonly used logic, memory, and microcontrollers. Used in safety chip, automotive electronics, medical equipment electronics, digital video, radio frequency, data acquisition, level converter, frequency converter, universal MCU, car audio processor, lithium battery charging management chip<\/p>\n

Process characteristics<\/strong>
\nRefer to or meet JEDEC standards
\nCustomized design lead frame design and multi-specification pad size to meet different customer needs
\nGreen manufacturing, lead-free process<\/p>\n

Reliability test standard<\/strong>
\nThe test criteria is zero defects in 77 sampling units
