Hole Design 1. Through Hole Hole Spacing The spacing between the hole and the hole disc is required: B ≥ 5MIL; The minimum distance between the hole plate and copper foil: B1-B2 ≥ 5MIL; The minimum distance between the metal hole (PTH) and the plate edge (hole to outline) ensures the distance between the welding …
General Requirements for Components Layout The THD componentswith polarity or direction shall be in the same direction in layout and arranged as orderly as possible. For SMD components, if the direction is consistent, it should be consistent in X and Y directions as far as possible, such as tantalum capacitance. If the componentneeds to be …
Many engineers still have such problems after debugging PCB. We summarize the steps of debugging. Before we introduce the first to third steps: detection before power on, power on test & other work in the debugging of electronic circuit. This article we will introduce last step failure during commissioning. Step 5: Failure During Commissioning To find …

For a newly designed circuit board, there are some difficulties in debugging, especially when the board is large and there are many components. But if we master a set of reasonable debugging methods, debugging PCB will get twice the result with half the effort. PCB Debugging Steps 1. Observe PCB Board For the new PCB …
When you inspect PCB board, you must pay attention to some details. In order to be more prepared to ensure PCB board’s quality, we should pay attention to the following 9 tips. It is strictly forbidden to use grounded test equipment to touch the live TV, audio, video and other equipment of the bottom plate to test …
PCB design process is divided into six steps: network table input, rule setting, component layout, wiring, inspection, review and output. Last article we introduce the first 5 steps. Here we will introduce the last step: design output. Design Output PCB design can be output to printer or output photo drawing file. The printer can print …
PCB design process is divided into six steps: network table input, rule setting, component layout, wiring, inspection, review and output. Here will will introduce the first 5 steps. Input of Network Table There are two ways to input the network table. One is to use the OLE PowerPCB Connection function of PowerLogic, select Send Netlist …
PCB design is not a easy work. Last we talk about the Common Errors in Schematic Diagram and PCB, today we discuss the treatment of power supply and ground wire, common ground processing of digital circuit and analog circuit, the signal line is laid on the electric (ground) layer, treatment of connecting leg in large …
