Abstract
The utility model relates to a PCB board, and in particular relates to the oil-layer-covered structure. The aim is to provide a circuit board with a white oil coverage layer, wherein the circuit board with the white oil coverage layer has the advantages of convenient processing and reliable performance. The circuit board with the white oil coverage layer is provided with a green oil coverage layer which is used for covering the circuit surface. The white oil coverage layer is further arranged on the green oil coverage layer of the circuit board. The circuit board with the white oil coverage layer, which is provided by the utility model, has the advantages that a layer of white oil is additionally printed again, so that the ink layer of a dense fine circuit can be thickened; and the electrical properties of a finished product after tin soldering are great.
Description
Technical field
The utility model relates to pcb board, relates to especially its oil overlay structure.
Background technology
Pcb board is exactly printed circuit board (PCB), almost can appear in the middle of each electronic equipment.And electronic component just is set on the pcb board of different sizes.Along with electronic equipment becomes increasingly complex, the part that needs is more and more, and circuit and part on the pcb board are also more and more intensive.This plate is heat insulation by insulation, also unbending material consists of substrate, the tiny line material that can see on the surface is Copper Foil, originally Copper Foil is to cover on the whole plank, and part is etched in manufacture process disposes, and the part that stays has just become webbed tiny circuit.These circuits are known as wire or claim wiring, and are used to provide the circuit connection of part on the pcb board.
Existing pcb board circuit surface only has green oil to cover, and does not have large tracts of land white oil piece.Dense wire and thin diameter line road surfaces only have green oil to cover, and to compare other position thinner for this position ink thickness when normal process, easily cause behind the scolding tin electric bad between circuit.
The utility model content
The purpose of this utility model provides a kind of wiring board with white oil cap rock of easy to process, dependable performance.
The technical scheme that realizes the utility model purpose is as follows: a kind of wiring board with white oil cap rock, have to cover the green oil cap rock on circuit surface, and also be provided with the white oil cap rock on the green oil cap rock of above-mentioned wiring board.This novel benefit is after again having printed additional one deck white oil, and the ink lay on intensive fine rule road is thickeied, and guarantees that the electric property of finished product is good behind the scolding tin.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
See Fig. 1, this novel wiring board with white oil cap rock has to cover the green oil cap rock 1 on circuit surface, also is provided with white oil cap rock 2 on the green oil cap rock of above-mentioned wiring board.After again having printed additional one deck white oil, the ink lay on intensive fine rule road is thickeied, and guarantees that the electric property of finished product is good behind the scolding tin.
Obviously, above-mentioned embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to the utility model execution mode.For those of ordinary skill in the field, can also be easy on the basis of the above description make other pro forma variation or alternative, and these changes or alternative also will being included within the definite protection range of the utility model.
Claims (1)
1. wiring board with white oil cap rock has to cover the green oil cap rock (1) on circuit surface, it is characterized in that: also be provided with white oil cap rock (2) on the green oil cap rock of above-mentioned wiring board.
