Dust guard structure
An apparatus includes a particle trap coupled to a first surface of an enclosure, wherein the first surface of the enclosure is opposite a top surface of a circuit board. A particle guard coupled to the top surface on a first side of the circuit board located in the enclosure, wherein the enclosure includes one or more apertures on a second surface of the enclosure where the first side of the circuit board is introduced to an external airflow.
1. An apparatus comprising:
a particle trap coupled to a first surface of an enclosure, wherein the first surface of the enclosure is opposite a top surface of a circuit board;
a particle guard coupled to the top surface on a first side of the circuit board located in the enclosure, wherein the enclosure includes one or more apertures on a second surface of the enclosure where the first side of the circuit board is introduced to an external airflow, wherein the particle guard is wedge shaped;
an electrostatically charged film coupled to a first surface of the particle guard, wherein the first surface of the particle guard forms an acute angle with the top surface of the circuit board; and
a plurality of electronic components coupled to the circuit board via a plurality of electronic connections, wherein a height of the particle guard is greater than a height of each of all the plurality of electronic connections.
2. The apparatus of claim 1 , wherein the particle trap includes an adhesive film coupled to a first surface of the particle trap opposite the top surface of the circuit board.
3. The apparatus of claim 2 , wherein the adhesive film coupled to the first surface of the particle trap is a first adhesive film out of a plurality of adhesive films stacked in arrangement.
4. The apparatus of claim 1 , wherein the particle trap further comprises an abrasive coating including a plurality of abrasive grains coupled to a first surface of the particle trap opposite the top surface of the circuit board.
5. The apparatus of claim 1 , wherein dimensions and a location of the particle trap is dependent on dimensions and a location of the particle guard.
6. The apparatus of claim 1 , wherein the particle guard diverts external airflow towards the particle trap.
7. The apparatus of claim 6 , wherein the enclosure includes one or more apertures on a third surface of the enclosure opposite the second surface of the enclosure for exhausting the external airflow introduced at the first side of the circuit board.
