Ekwesịrị ilebara nsogbu ndị ahụ anya mgbe akụrụngwa nkwụnye abanyePCB Mgbakọusoro

Ekwesịrị ịhọrọ akụkụ nke PCB n'ụzọ ziri ezi na ntọala nke imezu ihe achọrọ ọrụ sekit.Ekwesiri ighota na onu ogugu voltaji nke ihe ndi ozo nwere otu oru, ihe nlere anya na ndi ozo di iche iche nwere ike inwe oke di iche iche.Ya mere, olee nsogbu anyị kwesịrị ịṅa ntị mgbe ị na-etinye ihe na PCB?

1. Oke mmepụta ugbu a iji zere mmetụta mkpọchi nke sekit CMOS

Mkpọchi-na mmetụta bụ a pụrụ iche ọdịda mode nke CMOS circuit, n'ihi na e nwere parasitic PNP transistor na NPN transistor na esịtidem Ọdịdị nke CMOS circuit, na ha na-etolite parasitic PNPN thyristor Ọdịdị, otú mkpọchi-na mmetụta nke CMOS circuit bụ. A na-akpọkwa "thyristor mmetụta".

2. Iji netwọk nzacha

Mgbe ụfọdụ a na-achọ eriri ntinye ogologo n'etiti sistemụ sekit CMOS na kọntaktị igwe, nke na-abawanye ohere nke nnyonye anya electromagnetic.Yabụ, ekwesịrị ịtụle netwọkụ nzacha.

3. RC netwọk

Ebe ọ ga-ekwe omume, maka ntinye mmetụta nke ngwaọrụ bipolar, netwọk RC nke mejupụtara resistors nwere nnukwu nguzogide yana capacitors nwere opekata mpe 100pF nwere ike ibelata mmetụta nke mwepu electrostatic.

4. Akwụsịla ịzere pin nke tube ntinye maka CMOS.

Zenarị na a kwụsịtụrụ njedebe ntinye nke ngwaọrụ CMOS nke eresịrị na bọọdụ sekit.N'otu oge ahụ, ọ kwesịrị ịṅa ntị na ntinye ntinye niile na-adịghị mkpa na ngwaọrụ CMOS anaghị ekwe ka kwụsịtụrụ.N'ihi na ozugbo etinyere ntinye, ikike ntinye ga-adị na ọnọdụ anaghị akwụsi ike.

Ihe dị n'elu bụ nchịkọta nke nsogbu ndị ekwesịrị ịṅa ntị na usoro ntinye ihe na PCB.Enwere m olileanya na ọ ga-abara gị uru.Maka nkọwa ndị ọzọ, biko gaa na webụsaịtị anyị www.pcbfuture.com
