Abstract
The invention discloses a method for achieving mutual conduction of inner and outer surfaces of a plastic component. The method comprises the following steps of: drilling a through hole at a preset position of the plastic component by using laser; and activating and depositing a metal layer in a specific area to achieve the electric conduction of the inner and outer surfaces of the plastic component. Because the aperture of the through hole is very small, a filler is not required to be filled in the through hole, and the outer surface of the plastic component can be directly coated with a coating layer. Due to the small aperture, the through hole can be directly covered by the coating layer. The through hole is applied to the field, and because the minimum aperture of the through hole can reach 0.02mm, the filler is not required to be filled in the through hole; and therefore, the cost is saved and traces left on the outer surface when the filler is not completely removed and the surface is not well leveled are avoided. The method can be also applied to a production technique for fabricating a mobile terminal antenna onto a shell.
Description
Technical field
The present invention is applied to the electronic equipment manufacturing, portable terminal, multimedia equipment field; Can be applied to antenna and other use LDS and other with metal attached to the field of plastic parts spare surface as connection line or decorative effect.
Background technology
At present based on carry out on the plastic parts LDS (the direct moulding of LASER DIRECT STRUCTURE laser, or be called laser direct forming) or LSP (LASER SELECTIVE PLATING laser is selected plating) or other directly or between be connected on the technology of plating on the plastic parts.
With LDS is example, uses the LDS technology of three-dimensional laser system can the cad data of Antenna Design be transferred on the model antenna holder, perhaps directly transfers on the device structure, for example the portable terminal lid.Adopt follow-up lacquer spraying technique to decorate to antenna surface.The LDS technology adopts laser beam at the resinous complex three-dimensional piece surface initiative of LDS antenna pattern.This technological key advantage comprises can change design fast, and can on three-dimensional surface, formulate antenna structure.It is integrated that the LDS technology also allows the user to carry out higher levels of product, reduces parts and reduce cost.
The mutual conducting of plastic parts inner surface and outer surface if desired, its technology are perforates on plastic parts, and then carry out surface active and deposit going up metal level.For example mobile terminal antenna is a lot of now uses LDS or LSP technology to be made on the shell, and antenna is connected to inside from the outside just need via hole.In order to guarantee outward appearance and sealing property, often need use filler that the hole is blocked up, use coating to improve outward appearance then.Technology filler commonly used has glue at present, can be instant drying adhesive, AB glue, and UV glue or caulk compound are with the hole shutoff.
The method of concrete realization plastic parts inner surface and the mutual conducting of outer surface is shown in Figure 1A to Fig. 1 E:
Step 1: utilize mould on plastic rubber bracket, to carry out perforate, the aperture is generally greater than 0.5MM, and it is bigger that the hole on the plastic parts often will be opened; The mould upper and lower mould can be run into so here; Can influence die life if the hole is too small, and be easy to generate overlap, cause that thus fraction defective raises.
Step 2: laser activation and depositing metal layers in the specific region.Under the general situation, be in the hole, carry out laser activation around the hole, and deposition goes up metal level.Realize the effect of inner surface and the mutual conducting of outer surface through metal level.
Step 3: use the filler filling vias, in general, filler has glue, can be instant drying adhesive, AB glue, and UV glue or caulk compound are with the hole shutoff.
Step 4: on the customer-oriented one side of plastic parts, the filler of protrusion is removed, so that this surface energy is smooth.
Step 5: the one side after this is smooth covers and goes up coating.
Though above-mentioned process can realize the effect of plastic parts inner surface and the mutual conducting of outer surface, possibly there is following defective:
At first: it is bigger that the hole on the plastic parts often will be opened, and for example greater than 0.50, because the mould upper and lower mould can be run into here, can influence die life if the hole is too small, and be easy to generate overlap.And these through holes can influence sealing property, advance dust easily like portable terminal, and influence outward appearance.
Secondly: like the needs plug-hole; Then because that the hole often is difficult to very greatly to accomplish to cooperate with face on every side is fine; Such as in step 4, removing the clean or excessive filler of removing of filler; On coating, can leave a trace and cause bad order, especially on the coating of high glaze, usually the bad order rate is high.
Once more: the filler that plug-hole needs can increase cost of material, and production process is long, and unfavorable to environment.
