Tallo a pamay-an tapno malapdan ti anti-jamming ti circuit board .

Ti anti-interference a disenio ti PCB proofing production ket asideg a nainaig iti layout ti sirkito. no kasano ti agdisenio ken epektibo a mangkissay iti riribuk ti circuit anti-dry worry, ti sumaganad ket simple a panangilawlawag ti PCB anti-dry worry design problem!
1. Disenyo ti linia ti koriente: Segun iti kadakkel ti current ti proofing circuit board, iti disenio ti linya ti koriente agingga a mabalin tapno mapapuskol ti kalawa ti suplay ti koriente, maitutop a mapabassit ti loop resistance, tapno agtultuloy ti direksion ti linya ti koriente, ground ken data, daytoy a disenio ket makatulong a mangpapigsa iti anti-noise ability{2}} .
2. ground design: digital and analog should be separately designed, if the circuit board has both logic circuit and linear circuit, the design should try to separate it. Even low-frequency circuits should be as far as possible to use a single point of parallel grounding, the actual wiring difficulties can be partially connected and then grounded in parallel. The high frequency circuit board should be grounded in series, the ground should be short and rented, and the high frequency components should be surrounded by a large area of grid foil. As far as possible bold grounding wire design, such as grounding wire with a line, grounding potential changes with the change of current, so that its noise resistance performance is reduced. If it is designed with a thick grounding, it can pass through three times the current allowed on a printed board. In addition, when designing the grounding wire, it should form a closed-loop circuit as far as possible. The layer composed of digital Ti sirkuito, a ti sirkito ti grounding ket naurnos iti maysa a grupo a lubong, ket mabalin a mangpapigsa ti anti-arimbangaw nga abilidad aginggana ti maysa a tukad..
3. Lotus root capacitance configuration: Ti standard power input terminal ket naikonektar iti maysa nga electrolytic capacitor ti 10~100uf. tunggal IC chip ket rumbeng nga addaan iti 0.01PF ceramic capacitor. no ti giwang ti naimaldit a board ket saan nga umdas, maysa a capacitor ti 1~10 nga arved ti 10 nga arved ket saan nga umdas ti capacitor iti 1~10 a 210 a mabalin nga umdas, maysa a capacitor ti 100 a 10 a 210 a mabalin a 10 a 2. Chips. Ti decoupling capacitor ket rumbeng a direkta a maikonektar iti nagbaetan ti linia ti koriente ken ti alambre ti daga ti chip. kamaudiananna, laglagipen a ti capacitor lead ket saan a nalaka a mabayag unay, nangruna ti high-frequency side circuit ket saan a mabalin nga agparang a lead.
