Choosing the appropriate model of automatic soldering machine can make a product weld very well, so we must select the model before welding the product, only in this way can we be handy in the later welding process. So how to choose the model?

Now let's briefly introduce:

1. For points with proper spacing arrangement and regular spacing, we should choose the welding type of pull welding. At this time, we usually choose R (knife type) or D type for welding. When using R type, it is generally inclined, with a certain angle, rather than straight up and down. When using D type automatic soldering machine, it is generally straight up and down.

2. For products such as welding FPC soft board, it is advisable to choose PC or FPR type. In short, there are many kinds of shapes. The general principle is to choose what type of products to weld. Otherwise, it is easy to increase the defective rate of solder joints.

3. For large spacing or irregular arrangement of solder joints, we usually carry out spot welding one by one, that is, so-called spot welding. The type of automatic soldering machine suitable for this type is generally D or DV type, especially when there are many plug-ins like ammeters, it is inclined to choose this type. Type.

4. When the same product on the same machine needs spot welding and stretch welding at the same time, we tend to choose R-type or D-type. As for the choice of R-type or D-type welding, it depends on the distribution of solder joints and the distribution of components around the solder joints.
