PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is a board made by electronic printing, it is called a "printed" circuit board. FASTPCBA will share with you the matters needing attention in the process of drawing PCB.

When we generate the PCB from the schematic diagram, if we don't want the background, we can directly check the Add Component Class and Add Room. When drawing the positioning hole of the circuit board, the pad is used, and the pad is defined to the Multi-Layer layer. When we define the size of the circuit board, we need to select the origin first, and then draw the line, and when entering the length of the line, in order to ensure that there is no error in the length, it is often necessary to add two zeros after the length.

When drawing a double-sided circuit board, we are used to the mechanical layer to determine the size of the board, using Place-Line for marking, after drawing the line, we need to join (Union), and use Design-board shape-define from selected objects to determine the board the size of. After the mechanical layer is drawn, you need to copy this size to the Keep-Out-Layer layer. After determining the size of the board, you need to click Place-Dimension-Linear if you need to mark the size. The software defaults to the horizontal direction. If you want to draw the vertical direction, you need to confirm the point and click the space bar to change the direction.

When drawing a double panel, if you want to display only the top or bottom layer, just use the shortcut key Shift+s. Sometimes we often encounter that after the PCB is generated, it will automatically disappear when moving the components. In fact, the reason is very simple because we did not set its origin when we made the device package library, just reset the origin. .
