Embodiment

With reference to Fig. 1-18, its demonstration is filled some methods of at least one path with light transmissive material and is described hereinafter.The product that Figure 19 graphic extension is produced by one in the described method.The present invention utilizes path to drill technology and forms micro channels, fills described micro channels with light transmissive material then.Path drills known dawn in the irrelevant field that electron device is made.Path is formed in the multiple field interconnect substrate and adds and is lined with conductor (for example, copper) to allow the electrical connection between the different layers in the circuit.

Fig. 1 graphic extension method 10 and step of light transmissive material filling vias.Panel or substrate 12 are provided.As shown, panel 12 is relative thinner continuous material sheets.Panel 12 comprises first or the dorsal part 14 and opposed second or front side 18 of defining surface plate thickness 20.Front side 18 is level and smooth relatively and observe roughly complete with bore hole.Can make panel 12 by those skilled in the art known anodised aluminium or other material.

Method 10 comprises passes panel 12 and drills one or more micro channels or hole 30.As shown in Fig. 2-4,8 and 9, aspect of described method in, path 30 is coning and have first opening 40 in sidewall 34 and panel first side 14 and opposed second opening 44 on the panel side 18.The diameter of first passage opening 40 is greater than alternate path opening 44.In one aspect, first passage opening, 40 diameters are about 90-100 micron (μ m), and alternate path opening 44 diameters are about 30-40 micron (μ m).Should be understood that and to use greater or lesser cone shaped opening and other passage shape and configuration.

Use laser 24 (for example, diode pump solid state pulse laser) according to circle or spiral pattern from panel drill or machine work shown in path.Prove that it is useful having the pulse recurrence rate of 30kHz and the preferred conical path 30 of 22 pairs of machine works of Nd:YAG 355 nanometer hot spots of~60 millimicrosecond pulse width.Pass drilling of panel 12 18 realization exemplary paths 30 towards the front side from dorsal part 14.Can use other type laser with different characteristic and be different from known other process for machining that drills path of those skilled in the art and satisfy application-specific.

Optionally, method 10 comprises the step 46 of cleaning through drilling path 30 to remove any chip or the sediment that forms during process for machining.Prove CO 2The cleaning of snowflake jet flow and isopropyl alcohol be purge path effectively.Also can use other known path cleaning technique of those skilled in the art.For example, can use ultrasound wave to clean, described ultrasound wave cleans and uses for example ultrasonic bath.Equally, can come purge path from apply pressure-air (for example snowflake jet flow) with the source with the drilling machine 24 similar removable location of mode.

As shown in Fig. 1 and 5-9, method 10 comprises filler material coating 50 is put in the path 30.Filler material 50 can be the material of transmissive visible light.As illustrated, filler material 50 is curable, the acrylate polymers of optical clear ultraviolet ray (UV), and it is in liquid phase when putting on panel 12.Also can use other plastics or polymkeric substance with light transmission features.Exemplary ultraviolet-curing filler material is roughly transparent when solidifying.As best finding in Fig. 1, can path 30 second, filler material 50 is put on panel second side 18 on the top of optional smaller opening 44.Observe, by the exemplary liquid phase filler material 50 of relatively low viscosity, geometric configuration and the gravity of conical path 30, filler material 50 flows to path 30 and passes path 30 and flows to first side 14 from second side 18, thereby filling vias 30 effectively, as best finding among Fig. 1,8 and 9.Excessive filler material 50 can be in panel 12 second sides 18 (being shown as 66) and first side 14 (being shown as 62) diffusion, as best finding among Fig. 1.As shown, use syringe-type device 54 to apply filler material 52.Can use those skilled in the art known other filler material 50 bringing devices and technology.Example comprises ink-jet technology and intaglio plate transfer-print technology.

In alternative aspect, filler material 50 can be applied to dorsal part 14, so that filler material 50 flows to front side 18 to pass path 30 with the similar mode of described mode from dorsal part 14.

When using curable filler material, method 10 can comprise by filling agent 50 being exposed to ultraviolet light solidifies exemplary based on the step 76 of the filler material 50 of liquid phase silica.The free radical polymerization that is exposed to ultraviolet light 76 initial passes, 30 inboards and passes the silicate filler material 50 of path 30.In applying a kind of method of ultraviolet light, described ultraviolet light is applied to dorsal part 14 and path 30 (that is, big opening 40) to promote the curing of the filler material 50 in the path 30.When solidified, exemplary filler material 50 is optically transparent, thereby allows visible light to pass filling agent 50 and panel 12 via path 30.

Method 10 comprises the step 82 that removes any excessive or uncured filler material sediment 66 from visible, the front side 18 of panel, as shown in fig. 1.For example, can 18 remove filling agent excess deposition thing 66 from the front side by simple isopropyl alcohol, thereby stay visible level and smooth and clean Surface.Can use other method that removes excess deposition thing 66 and technology.

Optionally, method 10 can be included in after the step that removes excess deposition thing 66, and the filler material 50 of contiguous visible panel side 18 is to help all filler material 50 step of curing 90 in the path 30 in the exposure path 30.With reference to Fig. 9, the filler material 50 of the most contiguous panel visible surface 18 may be a shade below the front side 18 and form recess 94 between filling agent 50 and front side 18.

As best finding among Figure 10-18, can change the processing to the filler material of the visible panel surface 18 of direct vicinity, think that the user changes or the visual appearance of reinforcing filler material 40 and pass therebetween visible light.In the alternative aspect of method 10, with opposite in the recessed path 30 shown in Fig. 9, the excessive filling agent sediment 66 that has solidified can become convex shape or form.For example, two kinds of described convex form of the excessive filling agent sediment 66 that solidified of Figure 10-12 and Figure 13-15 graphic extensions.In Figure 10-12, described convex shape extends beyond and around alternate path opening 44.In Figure 13-15, described convex shape approximately is confined to the zone of alternate path opening 44.Can change the visible light that passes filler material 50 by different shapes or configuration (being similar to the shape or the configuration that change lens), to produce different visual appearances or effect to the user.As another example, the filling that Figure 16-18 graphic extension flushes (and and non-re-entrant or projection), that is, and filler material 50 and second or the embodiment of the flush of front side 18 wherein.

Method 10 through solidifying the protection path 30 that filler material 50 and front side 18 cause can printing opacity passing panel 12.As shown in Figure 19, use path and optical clear filler material to produce panel surface level and smooth and continuous concerning bore hole, described panel surface can throw light on internally and show controlled image by described path.Figure 19 graphic extension comprises backlight 70 panel 12, and backlight 70 can be LED, fluorescence or incandescent lamp or other light-emitting device.As shown in Figure 19, panel 12 can be the section that inserts in the shell, maybe can be the composition section of shell 72.

Gained panel 12 can be used for various application, described application comprises for example portable electric device of MP3 player, computing machine, cellular phone, DVD player.The method that this paper discloses and the panel of gained are applicable to nearly all following application: need vision continuously and uninterrupted and can produce the panel surface of illumination message, image or other Perception Features for the user.

Although in conjunction with thinking the most practical at present and most preferred embodiment is described described method, but should understand, the embodiment that described method is not limited to disclose, on the contrary, the present invention plans to contain spirit and interior various modifications and equivalent step and the layout of scope that is contained in the present invention and any appended claims.
