Embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
See also shown in Figure 1, on the pcb board 10 ' of prior art, be provided with certain isolation between the adjacent pad 30 ' of the welding region 20 ' that it is set, with the interconnection between the assurance function module, but, due to the isolation between adjacent pad 30 ', easily cause between adjacent pad 30 ' short circuit phenomenon to occur when welding, so that affect welding quality, and then have influence on the production efficiency of product.
See also shown in Figure 2, the utility model provides a kind of structure of anti-welding short circuit of pcb board, comprise the welding region 20 that is arranged on pcb board 10, be provided with the pad 30 that at least two intervals arrange in the scope of this welding region 20, and the surface at this welding region is provided with solder mask, and going back silk-screen on this solder mask has printing ink 40.By silk-screen on this welding region 20, printing ink 40 is arranged, with the isolation between increase adjacent pad 30, thereby effectively avoid short circuit phenomenon occurring between adjacent pad 30 when welding, then guaranteed welding quality.
Wherein, printing ink 40 refers to the printing ink 40 that printed circuit board (Printed CircuitBoard is referred to as PCB) adopts, and wherein important physical characteristic is exactly viscosity, thixotropy and the fineness of printing ink 40.Viscosity is exactly the interior friction of liquid, is illustrated under the effect of external force, one deck liquid is slided, the frictional force that internal layer liquid applies on another layer liquid.Thixotropy is a kind of physical characteristic of liquid, and namely its viscosity descends under stirring, recovers very soon again the characteristic of its original viscosity after standing.Fineness, pigment and mineral filler generally are solid-state, and through meticulous grinding, its particle size is no more than 4/5 micron, and form with solid shape form the flow regime that homogenizes.
Particularly, printing ink 40 is dielectric ink, and the thickness of this dielectric ink is 25 μ m～30 μ m.Wherein, adopt the printing ink 40 of this thickness range, except reaching the isolation that increases preferably between adjacent pad 30, can also avoid using too much printing ink 40, so that waste.
Particularly, be provided with three and the equidistant pad 30 that arranges in above interval in the scope of welding region 20.By being provided with the equidistant pad 30 that arranges in three and above interval, except being conducive to being connected between FPC and FPC or FPC and PCB, and then the interconnection between the assurance function module, can also the assurance function module between stable electrical connection.Preferably, described pad be shaped as ellipse, circle, rectangle or abnormity, and pad 30 is processed into the shape of such rule, not only be convenient to production and processing, and be convenient to arrange the isolation between pad 30.
