Abstract
The utility model relates to a kind of PCB consent plate, it is characterized in that comprising consent aluminium flake (1), circuit board (2), backing plate (3), through hole (4), via to be filled in (5), pod apertures (6) and screen frame (9).This patent is simple in structure, reasonable in design, easy to operate, has high practicality.
Description
Technical field
The utility model patent relates to a kind of PCB consent plate.
Background technology
The effect of the via hole (via) of PCB (printed circuit board (PCB)) is that conducting connects each layer pattern circuit, makes PCB entirety form a loop.In PCB industry, after via hole is the complete hole of machinery or laser processing, the electro-coppering of upper thickness more than 20UM by the heavy thin copper of last layer of chemical method, then electroplated on hole wall by elder generation, ensures its electrically conducting.Generally very little (through hole 0.7MM following) of via hole easily hides ink and liquid medicine in the anti-welding course of processing.But PCB is in element assembly welding process, short circuit is easily caused in other welding position that tin sweat(ing) can be sprayed onto to pcb board face after the ink in via hole or moisture are heated, secondly tin sweat(ing) also may cause short circuit through via hole to the welding position of component side from solder side, via hole hole copper is more easily oxidized in severe hot and humid and acid or alkali environment in addition, migration, attenuation, so must carry out special processing to via hole, the mode of processing comprises ink plugging, filling holes with resin, plating filling perforation and copper slurry grout.
Ink plugging adopts plugging green oil conventionally, and the mode of plugging green oil comprises aluminium flake consent and mesh screen plughole, is all normally consent before surface treatment.This consent tends to produce the phenomenon of plug, thereby makes screen-printing machine table top be stained with ink, and produces long-pending China ink at circuit board plate face, and then has increased cleaning cost, has caused the increase of cost.
Utility model content
The object of the utility model patent is to provide the measured PCB consent of a kind of consent matter plate, and for solving the problems of the technologies described above, the technical scheme that the utility model adopts is as described below:
A kind of PCB consent plate, is characterized in that comprising consent aluminium flake (1), circuit board (2), backing plate (3), through hole (4), via to be filled in (5), pod apertures (6) and screen frame (9);
Described circuit board (2) is positioned between consent aluminium flake (1) and backing plate (3), on this circuit board (2), there is via to be filled in (5) and consent (7) not, described consent aluminium flake (1) has through hole (4) corresponding to via to be filled in (5) position, described backing plate (3) has pod apertures (6) corresponding to via to be filled in (5) position, described through hole (4) is identical with the aperture of via to be filled in (5), and the 1.5-2 that the aperture of pod apertures (6) is via to be filled in (5) aperture doubly;
The outer rim place of described consent aluminium flake (1) has screen frame (9), and this screen frame (9) is fixedly connected with backing plate (3) by double-threaded screw (10);
The thickness of described consent aluminium flake (1) is 1.0mm, and the thickness of backing plate (3) is 1.8mm.
On described backing plate (3), there is reference column (8), backing plate (3) is detachably arranged.
The bottom of described backing plate (3) is provided with bonding sheet (11).
Beneficial effect:
This patent is simple in structure, reasonable in design, easy to operate, set up the backing plate with pod apertures, circuit board can directly not contacted with screen-printing machine table top, and the design of pod apertures can be played the effect of air guide and water conservancy diversion effectively, avoid because the phenomenons such as plug, the false leakage copper of peritreme freely do not appear leaking in air guide, and then improve quality, reduce defective products and do over again, the consumption that reduces cleaning cost, rework cost and consent material, reduces production costs, and has high practicality.
