Abstract
The utility model discloses a PCB flange gummosis mouth structure, the flange of inner plating have a round sheet frame, the surface of sheet frame has a plurality of bellied rhombus copper beans, the even interval distribution of all rhombus copper beans in sheet frame surface, and interval between rhombus copper beans and the rhombus copper beans constitutes the gummosis recess that circulates, rhombus copper beans evenly distributed is at the interior border from the sheet frame towards outside along 2 to 10 millimeters within ranges. During the pressfitting, unnecessary glue flows out in can following the gummosis recess, consequently, can accelerate the gummosis time, promotes the gummosis homogeneity simultaneously, and it is smooth and easy to make the bubble discharge, avoids leading to the fact the pressfitting fold.
Description
Technical field
This utility model belongs to art of printed circuit boards, is specifically related to a kind of internal layer pressing gummosis mouth。
Background technology
Multi-layer sheet is to be formed by multiple inner plating pressings, the opposing two sides of each inner plating is respectively provided with multiple hot melt block, the position of the hot melt block of the plurality of inner plating is correspondingly arranged, make to form an interval between adjacent two inner plating, when multiple inner platings carry out pressing hot melt, need to place in the interval between two adjacent inner platings a PP film, after PP film hot melt, become gluey, levelling between two adjacent inner platings, thus bonding adjacent two inner platings, unnecessary glue then flows out along the gummosis mouth of the edges of boards of each inner plating, thus it is fixing to realize being mutually bonded of the plurality of inner plating。
At present, edges of boards gummosis mouth is formed (becoming tangent between circle bean bean with circle bean bean) side by side by the round bean bean that diameter is 1.8MM and is only located at rivet hot block region, and other regions are not designed, and cause gummosis uneven, bubble row do not go out, thus causing that pressing gauffer scrappage rises。
Utility model content
In order to solve the problems referred to above, this utility model provides a kind of pcb board limit gummosis mouth structure, and this pcb board limit gummosis mouth structure can accelerate the gummosis time, promotes gummosis uniformity simultaneously, makes bubble discharge smooth and easy, it is to avoid to cause pressing gauffer。
This utility model be the technical scheme is that to solve its technical problem
A kind of pcb board limit gummosis mouth structure, the edges of boards of inner plating have a girth sheets frame, the surface of described sheet frame has the rhombus copper bean of multiple projection, all rhombus copper bean uniform intervals are distributed in sheet frame surface, spacing between rhombus copper bean and rhombus copper bean constitutes the gummosis groove of circulation, and described rhombus copper bean is evenly distributed on from the inside edge of sheet frame towards within the scope of outer edge 2 to 10 millimeters。
The further technical scheme that this utility model adopts to solve its technical problem is:
Saying further, the length of side of described rhombus copper bean is 0.9 to 1.5 millimeter, and in 40 ° to 50 ° angle arrangements between described rhombus copper bean and rhombus copper bean, the width of described gummosis groove is 0.2 to 0.5 millimeter。
Saying further, the length of side of described rhombus copper bean is 1.04 millimeters, and the arrangement in 45° angle between described rhombus copper bean and rhombus copper bean, the width of described gummosis groove is 0.3 millimeter。
Saying further, described inner plating is to be unified the connection sheet that typesetting is constituted by multiple single piece plate, and described sheet frame is the peripheral sheet frame of whole sheet。
Saying further, the height of described rhombus copper bean is 1/4 to 2 ounce。Preferably, the height of described rhombus copper bean is 1/3 ounce。
The beneficial effects of the utility model are: the pressing gummosis mouth by inner plating four limit of the present utility model is designed to be covered with the impartial rhombus copper bean of edges of boards, gummosis groove is constituted between rhombus copper bean and rhombus copper bean, during pressing, unnecessary glue can flow out from gummosis groove, therefore, it is possible to accelerate the gummosis time, promote gummosis uniformity simultaneously, bubble is made to discharge smooth and easy, it is to avoid to cause pressing gauffer。
