Na imewe usoro nke hPCB dị elu, wiring bụ nka kacha zuo ezuo na nke pere mpe, ndị injinia na -enwekarị nsogbu dị iche iche na usoro a. Edemede a ga -ebu ụzọ mee PCB mmeghe, ma n’otu oge ahụ mee nkọwa dị mfe maka ụkpụrụ nke ịwụnye, n’ikpeazụ ga -eweta nka na ngwa wiwi PCB anọ dị mkpa.

Here are some good wiring tips and essentials:

Nke mbụ, a na-eme mmalite mmalite. Enwere ike kewaa ọnụọgụ nke PCB n’ime otu oyi akwa, okpukpu abụọ na ọtụtụ akwa. A na-ekpochapụ otu oyi akwa ugbu a. Ugboro abụọ oche osisi ihe ụda usoro na-eji ugbu a bụ nnọọ ukwuu, ọ bụ na-atụle n’ihi dị ka a na-emekarị na-etinye siri ike model osisi nwa, multi-Layer board point to 4 iru osisi nke 4 n’elu ya bụ, ka njupụta chọrọ nke akụrụngwa adịghị ogologo ga-. gwa ọkwa 4 zuru oke. Site na akụkụ nke oghere nwere ike kewaa site na oghere, oghere kpuru, na oghere eli ozu. Oghere site na oghere bụ oghere nke na-esi n’elu gaa na ala ozugbo; A na -eyi oghere kpuru ìsì site na oghere elu ma ọ bụ ala ruo na etiti dị n’etiti, mgbe ahụ ọ gaghị anọgide na -eyi.

Tupu wiring akpaka, wiring nwere nnukwu ihe achọrọ nke ahịrị mmekọrịta tupu oge eruo, ntinye na ahịrị akụkụ mmepụta ekwesịghị ịdị n’akụkụ, iji zere ndabichi ntụgharị. Ọ bụrụ na ọ dị mkpa, enwere ike iji eriri ala maka ịnọpụ iche, na wiring nke abụọ dị n’akụkụ kwesịrị ịdị n’otu n’otu, n’ihi na akwa ndị yiri ya na-emepụta njikọ parasitic. Ọnụ nkesa nkesa wiring na-adabere na nhazi dị mma, enwere ike ịtọ iwu wiring tupu oge eruo, dị ka ọnụọgụ ahịrị ahịrị, ọnụ ụzọ oghere, ọnụ ọgụgụ nrịgo, wdg. It is to undertake exploration type wiring first commonly, connect short line quickly, pass maze type wiring again, the connection that wants cloth undertakes global wiring route optimization, it can disconnect the line that already cloth according to need and try to re – route again, improve overall wiring effect thereby.

Maka nhazi nhazi, otu iwu bụ idobe dijitalụ na analọgụ dị iche iche dịka o kwere mee, otu iwu bụ idobe ọsọ dị ala pụọ ​​na nnukwu ọsọ. Ụkpụrụ kachasị mkpa bụ ikewapụ ntọala dijitalụ na ntọala analog. Digital grounding bụ a ịgbanwee ngwaọrụ, na ugbu a bụ nnọọ nnukwu n’oge nke mgba ọkụ, na nnọọ obere mgbe ọ na-adịghị akpali. Ya mere, enweghị ike ịgwakọta ala dijitalụ na ala analog. Okirikiri nhọrọ akwadoro nwere ike ịdị ka nke dị n’okpuru.

1. Akpachara anya maka wiring n’etiti ọkụ ọkụ na waya ala

(1) Iji tinye ike ngbanwe n’etiti ọkụ ọkụ na waya ala. Jide n’aka na ị ga-ejikọta ọkụ eletrik na pin nke mgbawa mgbe onye na-emepụta ihe na-emepụta ihe, ọnụ ọgụgụ na-esonụ na-edepụta ọtụtụ usoro njikọ na-ezighị ezi na usoro njikọ ziri ezi, anyị na-ezo aka na-esote, enwere mmejọ dị otú ahụ? Decoupling capacitor generally has two functions: one is to provide the chip with instantaneous large current, and the other is to remove the power supply noise. On the one hand, the noise of the power supply should be minimized to affect the chip, and on the other hand, the noise generated by the chip should not affect the power supply.

(2) ruo ka o kwere omume ịgbasa ike ọkọnọ na waya ala, waya ala kacha mma sara mbara karịa eriri ọkụ, mmekọrịta ya bụ: akara akara “akara ike” nke ala.

(3) nwere ike iji nnukwu ebe nke ọla kọpa oyi akwa dị ka ala, na e biri ebi osisi na-adịghị eji na ebe na-ejikọta na ala, n’ihi na ala ojiji, ma ọ bụ mere nke multi-layer, ike ọkọnọ, ala ọ bụla ogide a oyi akwa.

2. Digital sekit na analog circuit mixing nhazi

N’oge a, ọtụtụ PCBS abụghịzi sekit na-arụ otu ọrụ, mana ha mejupụtara ngwakọta nke sekit dijitalụ na nke analog, yabụ, nnyonye anya dị n’etiti ha kwesịrị ịtụle mgbe ị na-ebugharị, ọkachasị nnyonye anya mkpọtụ na ala.

N’ihi na elu ugboro dijitalụ sekit, analọg sekit sensitivity siri ike, n’ihi na mgbaàmà ahịrị, elu ugboro mgbaama dị ka o kwere omume n’ebe dị nro analọg ngwaọrụ, ma maka dum PCB, PCB ala waya na n’èzí ụwa ọnụ nwere ike inwe naanị otu. , otú ahụ ga-abụ n’ime PCB nhazi, dijitalụ circuit na analọg nsogbu sekit, na n’ime sekit osisi, Ala nke sekit dijitalụ na ala nke sekit analog dị iche iche, naanị na interface (plug, wdg) ebe PCB jikọtara ya na ụwa dị n’èzí. Ala nke sekit dijitalụ dị ntakịrị ntakịrị nke ala nke sekit analog, biko mara na e nwere naanị otu njikọ njikọ, enwerekwa ala na-adịghị ahụkebe na PCB, nke a dabere na nhazi usoro.

3. Nhazi nke akụkụ ahịrị

Dị ka ọ na-adịkarị, a ga-enwe mgbanwe na ọkpụrụkpụ na nkuku nke ahịrị ahụ, ma mgbe akara akara gbanwere, a ga-enwe ihe ngosi ụfọdụ. Maka ọdịiche ọkpụrụkpụ ahịrị, akụkụ aka nri kacha njọ, ogo 45 ka mma, na akụkụ gbara okirikiri kacha mma. Agbanyeghị, akụkụ gbara okirikiri na-enye nsogbu maka imewe PCB, yabụ a na-ekpebikarị ya site na mmetụta nke mgbama. Na mkpokọta, akuku ogo 45 zuru oke maka mgbaama ahụ, ọ bụ naanị ahịrị ndị ahụ nwere oke mmetụta chọrọ nkuku okirikiri.

4. Lelee iwu imewe mgbe ịtọchara ahịrị

N’agbanyeghị ihe anyị na-eme, anyị kwesịrị ịlele ya ma anyị mechaa ya, dị ka anyị kwesịrị ịlele azịza anyị ma ọ bụrụ na anyị nwere oge fọdụrụ n’ule ahụ, nke bụ ụzọ dị mkpa anyị ga-esi nweta akara dị elu, ọ bụkwa otu ihe ahụ nye anyị. ise PCB mbadamba. N’ụzọ dị otú a, anyị nwere ike ijide n’aka na mbadamba sekit anyị na-ese bụ ngwaahịa ruru eru. Nyocha anyị n’ozuzu nwere akụkụ ndị a:

(1) ma anya dị n’etiti ahịrị na ahịrị, ahịrị na paịlị akụrụngwa, ahịrị na oghere, paịpụ akụrụngwa na oghere, oghere na oghere nwere ezi uche, ma ọ bụ imezu ihe ndị a chọrọ.

(2) Ma obosara nke eriri ọkụ na eriri ala dabara adaba, ma ọkụ eletrik na eriri ala na-ejikọta ya (mkpọda ikuku dị ala), yana ma enwere ohere na PCB maka eriri ala ka gbasaa.

(3) Ma ewere usoro kachasị mma maka ahịrị mgbama igodo, dị ka ogologo kacha nso, ahịrị nchedo, ahịrị ntinye na ahịrị mmepụta na -ekewapụtara nke ọma.

(4) Circuit analog na akụkụ sekit dijitalụ, ma enwere waya ala nwere onwe ya.

(5) Ma eserese (dị ka ICONS na ọkwa) agbakwunyere na PCB ga -ebute sekit dị mkpirikpi.

(6) Gbanwee ahịrị ụfọdụ na -adịghị eju afọ.

(7) Ma agbakwunyere usoro usoro na PCB, ma ịgbado ọkụ na -eguzogide na -emezu ihe achọrọ maka usoro mmepụta, ma nha ịgbado ọkụ kwesịrị ekwesị, yana ma ọ bụ na -etinye akara agwa na paịda ịgbado ọkụ nke ngwaọrụ, ka ka ọ ghara imetụta àgwà ọkụ eletrik.

(8) Ma a na-ebelata ihu etiti nke ike ọkọnọ ike na bọọdụ ọtụtụ, dị ka foil ọla nke ekpughere na mpụga bọọdụ nke ọkọnọ ike dị mfe ịkpata sekit dị mkpirikpi.

N’ihe niile, nkà na ụzọ ndị a dị n’elu bụ ahụmahụ, nke kwesịrị ịmụta mgbe anyị na-ese osisi PCB. N’ime usoro ịbịaru PCB, na mgbakwunye na nka nke iji ihe osise, anyị kwesịkwara inwe ihe ọmụma siri ike na ahụmịhe bara uru, nke nwere ike inyere gị aka mezue maapụ PCB gị ngwa ngwa na n’ụzọ dị irè.
