Abstract
The invention discloses a linked printed circuit board structure for a display light-emitting diode (LED) backboard. The linked printed circuit board structure comprises a plurality of circuit board wafers which are connected with one another, wherein each circuit board wafer comprises opposite two surfaces; the two surfaces are a front copper surface and a reverse copper surface; each reverse copper surface is covered with a white reflection layer; each front copper surface is covered with an organic solderability preservative film, and is provided with a plug-in bonding pad and a surface mounting part bonding pad; the linked printed circuit board comprises one surface and another surface, which are opposite; and each circuit board wafer is that each front copper surface covered with the organic solderability preservative film is located on one surface of the linked printed circuit board and each reverse copper surface covered with the white reflection layer is located on the other surface of the linked printed circuit board. In the manufacture procedure, the white reflection layers are not stained with the organic solderability preservative films, so that the appearance and the reflecting property of the linked printed circuit board structure are ensured.
Description
Technical field
The invention belongs to art of printed circuit boards, be specifically related to a kind of connection sheet printed substrate for display led backboard.
Background technology
At present, the wiring board of LED backplane is that connection sheet is produced when producing, and type-setting mode is typesetting alternating between negative and positive, namely be in positive and negative setting between adjacent monolithic, the copper face of one piece of monolithic is upper, the ink surface of adjacent monolithic is upper, this kind of structure is through anti-oxidant processing procedure OSP (organic guarantor welds film) line, copper face OSP film can stick on roller, OSP film on roller can be instead stained with on the ink of wiring board another side, cause product heterochromatic through SMT plug-in unit high temperature process plate face ink surface, cause bad order and function of surface to weaken.
Summary of the invention
In order to solve the problem, the invention provides a kind of connection sheet printed circuit board structure for display led backboard, this organic guarantor for the connection sheet printed circuit board structure of display led backboard welds film and can not be stained with white reflecting layer, thus ensures outward appearance and the reflecting properties of product.
The present invention in order to the technical scheme solving its technical problem and adopt is:
A kind of connection sheet printed circuit board structure for display led backboard, comprise interconnective multi-disc wiring board monolithic, it is characterized in that: wiring board monolithic described in every sheet all has two relative surfaces and is front copper face and reverse side copper face, described reverse side copper face is coated with white reflecting layer, described front copper face is coated with organic guarantor and welds film, described front copper face have plug-in unit pad and surface mount part pad, described sheet printed substrate has relative one side and another side, every sheet wiring board monolithic is all be coated with front copper face that organic guarantor welds film to be positioned at the one side of connection sheet printed substrate and the reverse side copper face being coated with white reflecting layer is positioned at the another side of connection sheet printed substrate.
The present invention in order to the technical scheme solving its technical problem and adopt is:
Say further, described surface mount part pad is welded with LED chip.
Say further, described plug-in unit pad is welded with plug-in element.
Say further, the base material of described wiring board monolithic is Double-sided copper clad laminate.Furthermore, the base material of described wiring board monolithic is CME-3 base material.
Say further, described white reflecting layer is white ink layer.
The invention has the beneficial effects as follows: the reverse side copper face of the every sheet wiring board monolithic of the present invention on the connection sheet printed substrate of display led backboard is coated with white reflecting layer and front copper face is coated with organic guarantor welds film, front copper face have plug-in unit pad and surface mount part pad, every sheet wiring board monolithic is all be coated with front copper face that organic guarantor welds film to be positioned at the one side of connection sheet printed substrate and the reverse side copper face being coated with white reflecting layer is positioned at the another side of connection sheet printed substrate, therefore, the present invention is in processing procedure, organic guarantor welds film and can not be stained with on white reflecting layer, thus ensure outward appearance and the reflecting properties of product.
