Abstract
Embodiments of the invention involve a technique and process for coating fine diameter, single strand wire of long continuous lengths with Parylene. The special fixture design and process allows for ultra thin (as thin as 0.2 micron), pore free, coatings. The advantages of this technology allow for wire products that offer minimal intrusion, superior routing and winding characteristics, and high heat and chemical resistance. The coating process can also be used for other types of material.
Claims9
A system for suspending a length of wire substantially in free space within a vacuum chamber to deposit a dielectric material onto the entire outer surface of the wire by vapor deposition, comprising:
- a vacuum chamber;
- a controller;
- a bobbin located within the vacuum chamber, comprising:
- a top plate having a plurality of slots,
- a bottom plate having a plurality of slots,
- a plurality of notched struts having a spigot formed at each end, where a first spigot is inserted into one slot of the top plate and the other spigot is inserted into an associated slot of the bottom plate such that the notches are facing outwards away from a center of the bobbin,
- a plurality of threaded rods for securing the top plate to the bottom plate;
- and
- an actuator mechanically coupled with the top plate and electrically coupled to the controller;
- wherein the controller is configured to drive the actuator to vibrate the bobbin within the vacuum chamber such that the wire wound around the bobbin and passing through the notches is intermittently suspended in the free space and the entire outer surface of the wire is coated by vapor deposition.
