Inadvertent burning of circuit boards or other troubles can be prevented by adjusting appropriate laser shapes such as an oval (ellipse) or a ring-shape. In addition, a beam-splitting technology provides \u201ctwin-spot laser\u201d, which enables the simultaneous soldering of two joints.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n

Choose the laser type most suitable to the customer\u2019s board pattern and components.
\nFor example, if the pad has an ellipse shape, expose it with the oval type. Also, if the through-hole has black resin or other components on the back, use the ring type to prevent the laser burning it.<\/p>\n

Why don\u2019t you consider to choose laser beam shapes, alike choosing tip shapes for manual soldering?
\nFor example, the oval ring beam should be used on an oval-shaped pad. If a through-hole component is underlain by another component or black resin, the ring-type beam should be used to prevent burning by the laser.<\/p>\n

\n Contact soldering method,\u201dThermal conduction\u201d and \u201csurface heat generation\u201d for laser have different heating principles. Both laser and soldering characteristics must be understood and well-handlled, otherwise the advantages of each method won\u2019t be realized. The first main is to use it with careful consideration about heat application conditions. It is actually an established technique, and depending on the way it is used.\n <\/p>\n
