Analysis of the Causes of missing or Damaged components during the SMT solder paste assembly Process

Today, with the rapid development of electronic technology, yesSMTSolder pasteThe requirements for surface mount technology (SMT) processing are still relatively high, and occasionally some problems may occur, such as missing parts or damaged parts. All these poor processing phenomena are necessarySMTThe operators in the factory need to identify the causes of the problems and solve them in a timely manner to ensure the processing quality, which can bring customers a satisfactory processing service experience. Shenzhen JJYSolder paste manufacturerLet's summarize the reasons for everyone and learn together:

SMTThe main reason for missing items:

1The incoming materials of the circuit board are of poor quality, resulting in deformation;

2The solder pads of the circuit board are not coated with solder paste or there is too little solder paste;

3The incoming components are of poor quality, and the thicknesses of materials of the same model are different;

4The feeding frame fails to deliver materials properly.

5The suction nozzle of the component is clogged.

6If there is dirt or cracks on the end face of the suction nozzle, this phenomenon will cause air leakage;

7The height of the surface mount technology (SMT) processing is inappropriate due to the thickness of the components orzThe setting error of the shaft height should be corrected according to the actual value after inspection;

8The coordinates of the picking pieces are inappropriate. This might be because the feeding center of the feeder has not been adjusted properly. The feeder should be readjusted.

The above are some possible reasons for the occurrence of missing or damaged parts. Of course, there may be other reasons that could lead to such adverse situations.
