Open Cavity QFN Package
Open cavity (air cavity) organic semiconductor packages for quick-to-market applications. Excellent for fabless prototype, probing, RF, MEMS and sensor. Use for R&D, laboratory projects and pre-production where low volume, low cost is required.
Our organic packages can be delivered quickly. Faster than developing LTCC ceramic packages from scratch. Our soft-tooled packages are much cheaper than tooling injection molded packages.
Our Open cavity package is made using semiconductor grade BT copper clad organic substrates. For RF and special applications Rogers RO4003C and other composites are avaulable.
Organic substrates are made using microelectronic PC board fabrication technique. Build-up dispensing of liquid encapsulation creartes the cavity dam wall. Recommended for fabless prototyping and pre-production requirements. Customized version are available.
Features to suit your specific packaging needs:
- Available singulated for one-off assembly, or panelized array for step-and-repeat wire-bonding.
- Die cavity 50 µ-inch (1.3 µm) plating for gold wire-bonding.
- Bottom side is thin gold ENIG plated for optimum SMT RoHS lead-free soldering.
