Abstract
The utility model relates to a PCB (printed circuit board), and especially relates to a cover oil layer structure of the PCB. The purpose of the present utility model is to provide a PCB that is convenient to process and reliable in performance and has a secondary solder resistant protective layer. The PCB having the secondary solder resistant protective layer has a green oil cover layer for covering the surface of a circuit. The secondary resistant protective layer is positioned at the edge of the PCB and the periphery of a threaded hole. The advantage of the PCB having the secondary solder resistant protective layer is that after the added printed secondary solder resistant protective layer, an ink layer of a dense fine circuit is thickened, and the wear resistance of the circuit board is enhanced without affecting the performance of the PCB.
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 there will be in the middle of each electronic equipment.And electronic component is just set on the pcb board of different sizes.Along with electronic equipment becomes increasingly complex, the part needing is more and more, and circuit and part on pcb board are also more and more intensive.This plate is heat insulation by insulating, also unbending material forms substrate, the tiny line material that can see on surface is Copper Foil, originally Copper Foil is to cover on whole plank, and in manufacture process, part is etched disposes, and the part staying 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 pcb board.
Existing pcb board circuit surface only has green oil to cover, and dense wire and thin diameter line road surfaces only have green oil to cover, and in the time of normal process, this position is rubbed, and easily causes leaking copper phenomenon.
Utility model content
The purpose of this utility model is to provide a kind of pcb board with secondary welding resistance protective layer of easy to process, dependable performance.Complete after solidifying and increase secondary solder mask in welding resistance ink silk screen printing, thereby prevent that plate face from wiping flower wearing and tearing, prevent from scrapping, increase product useful life.
The technical scheme that realizes the utility model object is as follows: a kind of pcb board with secondary welding resistance protective layer, there is the green oil cap rock for covering circuit surface, and on the green oil cap rock of above-mentioned wiring board, be also provided with secondary welding resistance protective layer.Above-mentioned secondary welding resistance protective layer is positioned at edge and the screw hole periphery of pcb board.This novel benefit is again to have printed additional after one deck secondary welding resistance protective layer, and the ink layer on intensive fine rule road is thickeied, and is not affecting under the prerequisite of the performance of product own, has strengthened circuit board resistance to wear.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Embodiment
See Fig. 1, this novel pcb board 1 with secondary welding resistance protective layer, has the green oil cap rock for covering circuit surface, and the edge of above-mentioned pcb board 1 goes out with screw hole 2 to be also provided with secondary welding resistance protective layer 3 around.
When production, pass through to increase printed board text addition silk-screen layer; flower is easily being wiped in printed board; leaking copper and insert row solder joint position increases secondary welding resistance protective layer ink, in product processing, without increasing operation, can in engineering data, extention directly be designed and be superposeed.Do not affecting under the prerequisite of the performance of product own, on welding resistance green oil layer surface, at panel edges and screw hole edge etc., place easy to wear increases character layer protective layer; accentuator plate resistance to wear; thereby prevent that plate face from wiping flower wearing and tearing, prevent from scrapping, increase product useful life.
Obviously, above-mentioned embodiment of the present utility model is only for the utility model example is clearly described, and is not the 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 substitute, and these changes or alternative also by within being included in the definite protection range of the utility model.
Claims (2)
1. there is a pcb board for secondary welding resistance protective layer, there is the green oil cap rock for covering circuit surface, it is characterized in that: on the green oil cap rock of above-mentioned wiring board, be also provided with secondary welding resistance protective layer (3).
2. the pcb board with secondary welding resistance protective layer according to claim 1, is characterized in that: above-mentioned secondary welding resistance protective layer (3) is positioned at edge and screw hole (2) periphery of pcb board (1).
