The change of squeegee pressure has a significant impact on printing. Too small pressure will make the solder paste unable to effectively reach the bottom of the stencil opening and not be well deposited on the pad. Too much pressure will cause tin The paste is printed too thin and can even damage the stencil.
At present, the low-power laser and the medium-power laser are gradually being localized, while the superpower lasers are just beginning to be localized and is accelerating. How to improve the reliability of superpower lasers welding is an urgent tec
