The PV3104 is a single phase controller offered in the standard 5 mm x 5 mm QFN
package and is footprint compatible with the PV3202.
Kulicke and Soffa Industries Inc (K&S) (NASDAQ:KLIC), a company that designs and manufactures semiconductor and LED assembly equipment, on Wednesday announced the launch of the Quantis QFN
Capillary, a copper wire bonding capillary.
Cox added, One drawback of the hot solder dip process however is that the surface tension of the molten solder tends to form bulbous nodules of various heights on each of the QFN
One thing that's important to note is that despite sharing the first two letters (Q and F), QFP and QFN
footprints are not interchangeable.
can float during reflow if there is too much solder.
One of the perceived disadvantages of QFN
had been that on packages with this exposed copper, which generally gets oxidized prior to SMT reflow, it does not consistently wet with solder in typical SMT processes.
4-mm pitch QFN
84-pin ICs accommodates a 10-mm x 10-mm package and operates at bandwidths up to 10 GHz with less than 1 dB of insertion loss.
Texas Instruments introduced a family of 16-bit analog-to-digital converters (ADCs) packaged in a leadless QFN
Combined with our QFN
packaged MOSFET drivers, the ISL6561 precision controller provides VRM10 platform designers with everything they need to meet stringent performance, space and cost requirements," said Cindy Drapcho, director of Intersil's Desktop Power Products.
It allows designers to quickly explore various design specifications with accurate package information and implement optimized RFIC/MMIC designs, providing a greater range of choices and more flexibility when designing QFN
(QUAD flat pack, no leads) package can no longer be considered exotic.
The devices are in production now and are packaged as follows: M07860 in 5x5 millimetre (mm) quad-flat no-leads (QFN
), M07840 in 3x3 mm QFN
and the M07830 and M07835 Rosas in industry standard LC connector.
