Abstract

An encapsulant compound apparatus, includes a mechanical operator, and an insert disposed on a surface of the mechanical operator. The insert operates to capture foreign material in the encapsulant compound.

Claims (22)

1. A method of processing encapsulant compound, the method comprising:

processing encapsulant compound with a mechanical operator; and

capturing, by a first insert disposed on a surface of the mechanical operator, foreign material in the encapsulant compound, wherein the first insert is configured to capture the foreign material in the encapsulant compound as the surface of the mechanical operator rotates.

2. The method of claim 1 , wherein the first insert is a coil magnet placed within a hole in the surface of the mechanical operator.

3. The method of claim 1 , wherein the first insert is a rigid magnet pressed into a hole in the surface of the mechanical operator.

4. The method of claim 1 , wherein the insert first is fabricated of one of zinc, stainless steel, a titanium alloy, and a composite plastic.

5. The method of claim 1 , wherein the first insert is replaceable.

6. The method of claim 1 , further comprising:

disposing a second insert on the surface of the mechanical operator, wherein the second insert operates to capture the foreign material in the encapsulant compound.

7. The method of claim 1 , wherein the mechanical operator is characterized as a kneader, and wherein the method further comprises:

rotating a rotator shaft of the mechanical operator to operate a kneader cam of the mechanical operator to knead the encapsulant compound, wherein, when the kneader cam includes the surface with the first insert.

8. A method of processing encapsulant compound, the method comprising:

processing encapsulant compound with a mechanical operator characterized as a kneader, the kneader including a kneader cam on a rotator shaft, the kneader cam including a first insert disposed on a kneading surface of the kneader cam; and

wherein the first insert operates to capture foreign material from the encapsulant compound.

9. The method of claim 8 , wherein the first insert is a coil magnet placed within a hole in the kneading surface of the kneader cam.

10. The method of claim 8 , wherein the first insert is a rigid magnet pressed into a hole in the kneading surface of the mechanical operator.

11. The method of claim 8 , wherein the first insert is fabricated of one of zinc, stainless steel, a titanium alloy, and a composite plastic.

12. The method of claim 8 , wherein the first insert is replaceable.

13. The method of claim 8 , further comprising:

disposing a second insert on the kneading surface of the mechanical operator, wherein the second insert operates to capture the foreign material in the encapsulant compound.

14. The method of claim 8 , wherein the method further comprises:

rotating the rotator shaft to operate the kneader cam to knead the encapsulant compound, wherein, when the rotator shaft is rotated, the first insert operates to capture the foreign material in the encapsulant compound.
