Be also provided with the second steel mesh hole and third steel mesh hole on substrate, the second steel mesh hole is rectangle steel mesh, the second steel mesh hole it is opposite
Be respectively arranged with two first guide pads on two inner walls, third steel mesh hole is rectangle steel mesh, third steel mesh hole have the first corner,
Second corner, third corner and the 4th corner, the first edge are provided with the first fillet surface, and the second edge is provided with second and falls
Edged surface.
Further, the cross section of above-mentioned first guide pad is in a rectangular trapezoid.
Further, the end face of above-mentioned first guide pad has cambered surface, and the bottom of the first guide pad is provided with triangle branch
Bracer.
Further, above-mentioned third edge is provided with the first arc guide surface.
Further, above-mentioned 4th edge is provided with the second arc guide surface.
A kind of bonding wire steel net structure applied to SMT attachment line provided by the utility model, by the way that the second steel is arranged
Mesh and third steel mesh hole realize steel mesh reaming effect, can increase the throughput of scolding tin herein, after reducing
The bonding wire working hour of Duan Rengong saves material and improves working efficiency.
Detailed description of the invention
