bonding pad is too
thick or the edge of
resistance welding
film becomes worn.
厚度不足 The thickness
is not big enough
1)
范本上焊膏涂布不均；
The solder paste
coating is not even on
model;
2)
制作范本的材料太薄；
The material for
making model is too
thin;
3)
刮刀压力不当 （太小）
；
The pressure of
squeegee is improper
(too small);
4)
PCB 焊盘镀层太厚。
The coating of PCB
bonding pad is too
thick.
1)
选择厚度合适的模板； Choose
template with proper thickness;
2)
选择颗粒度和粘度合适的锡膏；
Choose the solder paste with
proper granularity and viscosity;
3)
调整刮刀压力； Adjust the pressur e
of squeegee;
4)
减小 PCB 厚度设置。 Reduce the
thickness setting of PCB.
拉尖 Icicles
1)
范本与 PCB 间距太
大； The space
between model and
PCB is too big;
2)
焊膏粘度太大。 The
viscosity of solder
paste is too big.
1)
适当调小刮动间隙； Reduce the
scraping space a little;
2)
选择合适粘度的锡膏。 Choose tin
paste of proper viscosity
位置偏移 placement
bias
1)
设备本身的位置精度
不好； the position
accuracy of
equipment is not right;
2)
焊膏印刷时对进入网
板开口部的均匀性差；
The paste surface is
not smooth when
passed into the stencil
hole.
3)
由刮刀及其磨擦因素
1)
调整设备的重复定位精度； Adjust
the reset positioning accuracy of
equipment;
2)
选择合适粘度的焊膏； Choose the
solder paste of proper viscosity;
3)
加强对网板的印刷压力。 Reinforc e
the printing pressure on mesh
plate.
