Grounding is one of the important means to suppress electromagnetic interference and improve the EMC performance of electronic equipment. The correct grounding mode can not only improve the ability of the product to suppress electromagnetic interference, but also reduce the external EMI emission of the product. Is there a general grounding method for reference? The …

For PCB designers, creating a schematic symbol library and PCB packaging library is a very basic but very important work. Only by ensuring the accuracy of the schematic symbol library and PCB packaging library can we ensure the smooth development of PCB design. This book systematically introduces the methods and skills of schematic symbols and …
At present, there are mainly four kinds of stencil commonly used in SMT process according to manufacturing methods: chemical etching stencil, laser cutting stencil, electroformed stencil and mixed process stencil. OLINA PCB will briefly introduce the manufacturing methods of these four kinds of stencil. Chemical Etching Stencil Chemical etching is to use corrosive chemical solution to eliminate the metal …
PCB Stack Design Stacking Mode The recommended stacking method of PCB is foil stacking.(show as Figure 1)Note: There are two kinds of PCB stacking design: one is the structure of copper foil with core, which is called foil stacking for short; The other is the core stack method. The core lamination method can be used …
Connection Design of Panelization And Auxiliary Edge V-CUT Connection V-CUT can be used when the PCB is connected in a straight line with flat edge and does not affect the device installation. V-CUT is straight through type and can’t turn in the middle. The recommended thickness of PCB required by V-CUT design is ≤ 3.0 …
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 …
