The reflow soldering process of SMT chip requires that the pads of two end chip components should be independent pads. When the pad is connected with a large area of ground wire, the cross paving method and 45 ° paving method should be preferred; the length of the wire leading from the large area ground wire or power line is greater than 0.5mm, and the width is less than 0.4mm; the wire connected with the rectangular pad should be led out from the center of the long side of the pad to avoid a certain angle.
