Conexant's CN7221 Home LAN PHY/AFE chip is packaged in a 32-pin TQFP
and priced at $5.95 in OEM quantities of 10,000.
The XRD9814 is available in 48-pin TQFP
packaging, and costs $5.30 in 1000 piece quantities.
The MCP8024 is supported by Microchip's MCP8024 TQFP
BLDC Motor Driver Evaluation Board (Part # ADM00557, $99.00), which is expected to be available on December 20.
The "standard" list of conversions includes SOWIC to DIP, DIP to SOIC, SOJ to DIP, DIP to JEDEC TO, PLCC to DIP, QFP to PGA, SSOP to DIP, VQFP to PGA, TSOP to DIP, TQFP
to QFP and many more combinations in RoHS and non-RoHS compliant forms.
According to Pericom, the PI7C9X111SL is a high performance PCIe-to-PCI bridge from its SlimLine PCIe Packet Switch and Bridge family that features low power and TQFP
small footprint packages, enabling volume applications such as notebook/PC, embedded, video surveillance, wireless, networking, PC peripheral (such as MFP) and digital TV.
For designed board, we use the 100-pin TQFP
Figure 1 is the acoustic image of a thin quad flat pack (TQFP
) used in a modestly priced consumer product.
The testing plan included localized extraction of the 80-pin TQFP
using the C3 extraction system; then the 68-pin LCC breakaway coupon was ROSE-tested and the total board was bag extracted for ion chromatography and modified ROSE testing.

The pin-to-pin compatible TW2815 and TW2816 use a 100-pin TQFP
package, are currently sampling, and will go mass production in Q2 2006.
The ML6652 is packaged in a small foot print 44-pin TQFP
configuration and dissipates less than 650 mwatt typically while transmitting 100 Mbps packet s.
