Akwan abiɛsa a wɔfa so siw anti-jamming of circuit board ano .
Mar 28, 2023
Anti-interference design of PCB proofing production no ne circuit layout. sɛnea wɔyɛ nhyehyɛe na wɔtew ɔhaw a ɛwɔ circuit anti-dry dadwen so no wɔ abusuabɔ kɛse, nea edidi so yi yɛ nkyerɛkyerɛmu a ɛyɛ mmerɛw a ɛfa PCB anti-dry worry design problem ho!
1. Power Line Design: Sɛnea proofing circuit board current no kɛse te, wɔ power line no nhyehyɛe mu sɛnea ɛbɛyɛ yiye biara sɛ ɛbɛma tumi a wɔde ma no trɛw ayɛ kɛse, a ɛfata sɛ ɛtew loop resistance no so, sɛnea ɛbɛyɛ a anyinam ahoɔden nhama, asase ne data a wɔde fa kwan so akwankyerɛ no yɛ nea ɛkɔ so daa no, saa nhyehyɛe yi boa ma tumi a ɛko tia dede.
2. Ground Design: Ɛsɛ sɛ wɔyɛ dijitaal ne analog wɔ ɔkwan soronko so, sɛ circuit board no wɔ logic circuit ne linear circuit nyinaa a, ɛsɛ sɛ nhyehyɛe no bɔ mmɔden sɛ wɔbɛtetew mu. mpo low-frequency circuits ɛsɛ sɛ ɛyɛ akyirikyiri sɛnea ɛbɛyɛ yiye sɛ wɔde point biako a parallel grounding bedi dwuma a, ankasa wiring nsɛnnennen no fã bi a wɔde wɔn ho abɔ ho na afei grounded frequency boarded wɔ frequency board ne shoushed ground ne ground, the ground intem into into inte Ɛnam grid foil. beaeɛ kɛseɛ bi so kɔsi sɛ ɛbɛyɛ yie a ɛyɛ bold grounding wire design, te sɛ grounding wire a ɛwɔ line, grounding potential nsakraeɛ a ɛwɔ current nsakraeɛ no mu, sɛdeɛ ɛbɛyɛ a ne dede resistance performance no so bɛtew{5}} sɛ wɔayɛ no ne grounding a ɛyɛ den a, ɛtumi fa mprɛnsa current a wɔma ho kwan wɔ printed board. so no fa layer of digital circuit, a wɔahyehyɛ ne grounding circuit no ayɛ no kuw loop no, betumi ahyɛ tumi a ɛko tia dede no mu den akodu baabi.
3. lotus root capacitance configuration: Standard power input terminal no wɔde abɔ electrolytic capacitor a ɛyɛ 10~100UF. IC chip biara ɛsɛ sɛ wɔde 0{5}}01PF ceramic capacitor. bere a gap of printed board is not enough, a 1~1~ Chips. Ɛsɛ sɛ decoupling capacitor no di nkitaho tẽẽ wɔ power line ne ground wire a ɛwɔ chip. no ntam awiei koraa no, kae sɛ capacitor lead no nyɛ mmerɛw sɛ ɛbɛyɛ tenten dodo, titiriw no high-frequency side circuit no ntumi nyi adi sɛ lead.
