SMT solder paste special common problems in the course of         

PCB board after soldering are tin beads produce

This is the SMT soldering process a relatively common problem, especially when the user is using a new initial supplier product or production process is unstable, more likely to have such problems, through the use of customer cooperation, and through us a large number of experiments, we analyze the causes solder beads may have the following aspects:  

1, PCB board preheat is insufficient when passing reflow;

2, reflow profile set unreasonable, the plate surface temperature and the temperature of the weld zone into the welding zone before a wide gap;

3, solder paste when removed from the freezer temperature fails to return fully;

4, paste open too long exposed to the air;

5, when the patch tin powder splashing in the PCB board surface;

6, printing or handling process, there is oil or water adhered to the PCB;

7, solder paste flux formulations unreasonable itself have non-volatile solvent or liquid additive or activator;     

Two key reasons above, it is possible to explain why the new replacement of solder paste is easy to produce such a problem, the main reason is the current predetermined temperature profile used in solder paste does not match, which requires customers to switch suppliers, the it has to obtain its solder paste suppliers are able to adapt to the temperature profile; the third, fourth and six possible reasons for the user caused by improper operation; fifth reason may be due to improper storage paste or more than shelf-life cause failures caused by solder paste tack free or low tack, when the patch caused a splash tin powder; a seventh reason to paste production technology vendor itself caused.
