11804205 · 2023-10-31 · ·

An injection moulded acoustic filter comprising a foil piece or filter structure having a plurality of micro-slits configured to act as acoustic channels through the foil piece for filtering sound waves impinging the foil piece. The micro-slits have a maximum slit width across a surface of the foil piece of less than one hundred micrometres and a combined slit length along the surface of the foil piece of at least five millimetres. An earplug comprising the acoustic filter. A method and mould for manufacturing the acoustic filter.

Applying mold chase structure to end portion of fluid ejection die

A method includes applying a mold chase to a fluid ejection die to at least partially define at least one cavity. The mold chase includes a feature to contact a fluid ejection portion of the fluid ejection die, and at least one structure separate from the feature to contact a first end portion adjacent a first end of the fluid ejection die. The method includes filling the at least one cavity with a mold compound to produce a molded carrier for the fluid ejection die.

A resin molding has a first surface and a second surface, wherein the second surface includes a rib, and wherein the first surface includes a glossy portion and a non-glossy portion.

POLYMER TRIM BREAKER HAVING GAS-BLOCKING FLAKES AND AN EPOXY COATING

A refrigerator includes an inner liner, an outer wrapper and a trim breaker that extends between the inner liner and the outer wrapper to define an insulated structural cabinet. The trim breaker includes a plurality of gas-blocking flakes, wherein each gas-blocking flake includes a longitudinal axis that extends substantially parallel with an elongated surface of the respective gas-blocking flake. The longitudinal axis and the elongated surface of each corresponding gas-blocking flake is oriented to be substantially parallel with a portion of an outer surface of the trim breaker located near the respective gas-blocking flake.

Wafer level transfer molding and apparatus for performing the same

A method includes placing a package structure into a mold chase, with top surfaces of device dies in the package structure contacting a release film in the mold chase. A molding compound is injected into an inner space of the mold chase through an injection port, with the injection port on a side of the mold chase. During the injection of the molding compound, a venting step is performed through a first venting port and a second venting port of the mold chase. The first venting port has a first flow rate, and the second port has a second flow rate different from the first flow rate.
