Abstract
Realize a method for plastic parts inner surface and the mutual conducting of outer surface, comprising: laser beats via on the position that plastic parts presets; In specific region activation and depositing metal layers, realize conducting of plastic parts inner surface and outer surface by metal level; Because via aperture is very little, do not need in the hole of via to use filler filler opening, can at the direct applying coating of the outer surface of plastic parts, these vias due to aperture very little thus can coated direct covering; The present invention will beat via and be applied to this area, owing to beating, via aperture is minimum can reach 0.02 millimeter, so just do not need to use filler to fill via, not only save cost, and avoid and remove the clean and surface flattening bad vestige left by outer surface of filler.The method can also be applied in a kind of production technology be produced on by mobile terminal antenna on shell by the present invention.
Description
Technical field
The present invention is applied to electronic equipment manufacturing, mobile terminal, multimedia equipment field; Can be applied to antenna and other use LDS and other metal is attached to the field of plastic cement pieces surface as connection line or decorative effect.
Background technology
At present based on plastic parts carries out LDS (the direct moulding of LASERDIRECTSTRUCTURE laser, or be called laser direct forming) or LSP (LASERSELECTIVEPLATING laser selects plating) or other directly or to be connected on the technique of plating on plastic parts.
For LDS, use the LDS technology of three-dimensional laser system the cad data of Antenna Design can be transferred on model antenna holder, or directly transfer on device structure, such as mobile terminal lid.Adopt follow-up lacquer spraying technique can also decorate antenna surface.LDS technology adopts laser beam at LDS resinous complex three-dimensional piece surface initiative antenna pattern.The key advantage of this technology comprises can change design fast, and can formulate antenna structure on three-dimensional surface.It is integrated that LDS technology also allows user to carry out higher levels of product, reduces parts and reduce costs.
If need plastic parts inner surface and the mutual conducting of outer surface, its technique is perforate on plastic parts, and then carries out surface active and the upper metal level of deposition.Such as mobile terminal antenna much uses LDS or LSP technique to be made on shell now, and antenna is connected to inside from outside just needs via hole.In order to ensure outward appearance and sealing property, often needing to use filler to be blocked up in hole, then using coating to improve outward appearance.The filler that current technique is commonly used has glue, and can be instant drying adhesive, AB glue, UV glue or caulk compound be by hole shutoff.
The method of specific implementation plastic parts inner surface and the mutual conducting of outer surface is as shown in Figure 1A to Fig. 1 E:
Step one: utilize mould to carry out perforate on plastic rubber bracket, aperture is generally greater than 0.5MM, and it is larger that the hole on plastic parts often will be opened; mould upper and lower mould can be encountered so herein; if hole is too small can affect die life, and easily produces overlap, fraction defective is caused to raise thus.
Step 2: at specific region laser activation and depositing metal layers.When general, be in hole, hole surrounding to carry out laser activation, and the upper metal level of deposition.Effect of inner surface and the mutual conducting of outer surface is realized by metal level.
Step 3: use filler filling vias, in general, filler has glue, can be instant drying adhesive, AB glue, and UV glue or caulk compound are by hole shutoff.
Step 4: in 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, then cover upper coating.
Although above-mentioned process can realize effect of plastic parts inner surface and the mutual conducting of outer surface, following defect may be there is:
Such as, first: it is larger that the hole on plastic parts often will be opened, and is greater than 0.50, because mould upper and lower mould can be encountered, if hole is too small can affect die life, and easily produce overlap herein.And these through holes can affect sealing property, as mobile terminal easily enters dust, and affect outward appearance.
Secondly: as needs plug-hole, then due to hole be often difficult to very greatly to accomplish to coordinate with around face fine, in step 4, such as remove filler totally or excessively do not remove filler, coating can be left a trace and cause bad order, especially, in the coating of high glaze, usually bad order rate is high.
Again: the filler that plug-hole needs can increase cost of material, and production process is long, and unfavorable to environment.
Summary of the invention
The first object of the present invention is to provide a kind of method realizing plastic parts inner surface and the mutual conducting of outer surface, needs to come with filler the technical problem of filler opening to solve in prior art with die punching.
The second object of the present invention is to provide a kind of mobile terminal antenna to be produced on the technique of shell, needs to come with filler the technical problem of filler opening to solve in prior art with die punching.
