USB2649-HZH VQFN48 semiconductor

The USB2649-HZH VQFN48 is an IC semiconductor component designed for circuit integration. Engineers and procurement specialists source it for board-level designs that require this specific part number. It is supplied in new condition and was first listed by the manufacturer on 21 February 2025.

VQFN48 package implications

The VQFN48 package provides 48 connection pads in a compact footprint suited to automated surface-mount assembly. This leadless format demands precise reflow soldering and careful PCB layout to ensure reliable joints. Inspection typically requires X-ray or automated optical equipment because the pads sit beneath the body.

Tape-and-reel readiness

The component is delivered in packaging compatible with pick-and-place machines, enabling high-volume production without manual handling. Standard moisture-sensitivity labelling allows proper storage and bake-out procedures before assembly. No additional software or configuration files accompany this hardware device.

Questions about this item

How many pins does the VQFN48 package of the USB2649-HZH provide for board connection?

The VQFN48 package provides 48 pins for surface-mount soldering to the PCB, arranged in a quad flat no-lead layout that matches the 48-contact footprint.

What PCB footprint and pad dimensions are required to mount the USB2649-HZH VQFN48?

A standard VQFN48 land pattern with 48 perimeter pads and a central thermal pad is required; the exposed pad must be soldered to the board for mechanical stability and heat transfer.

What is the correct reflow profile step that assemblers often skip when installing the USB2649-HZH VQFN48?

The central thermal pad must be stencil-printed with solder paste and fully reflowed; skipping paste on the pad leaves the device floating and causes open joints.
