Ziziphi iimpawu zombane zeebhodi zeesekethe eziguquguqukayo?

Kule post yeblogi, siza kujonga nzulu kwiimpawu zombane zeebhodi zesekethe eziguquguqukayo, sijonge ukuba zahluke njani kwiibhodi eziqinileyo kwaye kutheni zikhethwa kwizicelo ezithile.

Iibhodi zesekethe eziguquguqukayo, ezikwabizwa ngokuba zii-PCBs eziguquguqukayo okanye ii-FPCs, ziya zithandwa kakhulu kumashishini ahlukeneyo ngenxa yeepropathi zazo ezizodwa kunye neenzuzo ezininzi.Ezi bhodi eziguquguqukayo zinika enye indlela ebalaseleyo kwiibhodi zesekethe eziqinileyo, ngakumbi kwizicelo ezifuna izixhobo zombane ezixineneyo nezikhaphukhaphu.

1. Ukuba bhetyebhetye kunye nokugoba:

Enye yeenzuzo eziphambili zeebhodi zeesekethe eziguquguqukayo kukukwazi ukugoba kunye nokugoba ngaphandle kokulahlekelwa ukusebenza.Ngokungafaniyo neebhodi eziqinileyo, ezinqabileyo kwaye zinokwaphuka phantsi koxinzelelo, iiPCB ezibhetyebhetye ziyilwe ngezixhobo ezinokumelana nokugoba ngokuphindaphindiweyo.Oku bhetyebhetye kubalulekile kwizicelo ezifuna ukuba iibhodi zihambelane neemilo ezithile okanye zingene kwiindawo ezixineneyo.Iimpawu zombane zeebhodi zeesekethe eziguquguqukayo ziqinisekisa ukusebenza okuthembekileyo nasemva kwamawaka emijikelezo yokugoba.

2. Ulawulo lokuphazamiseka:

I-Impedance luphawu olubalulekileyo lombane oluchaphazela ingqibelelo yesiginali kwiisekethe zombane.Iibhodi zeesekethe eziguquguqukayo zinokulawula i-impedance, ukuqinisekisa ukuhanjiswa kwesignali echanekileyo ngaphandle kokuphazamiseka okanye ilahleko.Ngolawulo lwe-impedance, ii-PCB eziguquguqukayo zinokusetyenziswa kwizicelo ezisebenza rhoqo njenge-RF kunye neesekethe ze-microwave, apho ukuhanjiswa komqondiso ochanekileyo kubalulekile.Olu phawu lwenza ukuba lulungele usetyenziso olunje ngezixhobo zonxibelelwano olungenazingcingo kunye nezixhobo zokujonga zonyango.

3. Ukwenziwa kancinci:

Iibhodi zeesekethe eziguquguqukayo zinenzuzo ye-miniaturization ngenxa yobuncinci babo kunye nokukhanya.Zinokuveliswa ngobubanzi obucolekileyo bomqhubi kunye nobukhulu becandelo elincinci, ukuvumela ukuyilwa kwezixhobo zombane ezihlangeneyo kakhulu.Esi sixhobo sokwenza izinto ezincinci siluncedo kakhulu kwizicelo ezibambekayo kwindawo ezinje ngeefowuni eziphathwayo, izixhobo ezinxitywayo, kunye netekhnoloji ye-aerospace.Iimpawu zombane zeebhodi zeesekethe eziguquguqukayo ziqinisekisa ukusebenza okuthembekileyo kunye nokusebenza kakuhle kwamacandelo amancinci.

4. Ukumelana nokungcangcazela kunye nokothuka:

Enye ipropathi ephawulekayo yombane yee-PCBs eziguquguqukayo kukuxhathisa kwazo okugqwesileyo kwi-vibration kunye nokothuka.Ukukwazi kwabo ukufunxa kunye nokuchitha uxinzelelo lomatshini kubenza bathembeke kakhulu kwizicelo ezivezwe kwintshukumo engaguqukiyo okanye imeko erhabaxa.Iinkqubo ze-elektroniki kumashishini afana neemoto, i-aerospace kunye nokukhusela zihlala zisebenzisa iibhodi zeesekethe eziguquguqukayo kuba ziyakwazi ukumelana nokungcangcazela okukrakra kunye nokothuka ngaphandle kokunciphisa ukusebenza.

5.Ukuxhathisa ubushushu:

Iibhodi zesekethe eziguquguqukayo zibonisa ukumelana nobushushu obulungileyo kwaye zigcina ukusebenza kwazo kombane naphantsi kweemeko zobushushu obugqithisileyo.Le propati ibenza bafanelekele izicelo ezibandakanya amaqondo obushushu aphezulu okanye aphantsi, njengoomatshini boshishino okanye izixhobo zomkhosi.Izinto ezisetyenziselwa ukwenza ii-PCB eziguquguqukayo zinokumelana nokuguquguquka kobushushu kunye nokuthintela imiba yokusebenza enxulumene noxinzelelo lobushushu.

6. Ukwandisa imfezeko yomqondiso:

Iipropathi zombane zeebhodi zeesekethe eziguquguqukayo zinceda ukuphucula ingqibelelo yesignali, okubangela ukusebenza kakuhle ngokubanzi.Ilahleko yombane ephantsi, ulawulo lokusasaza umqondiso, kunye nokuncipha kweeparasikhi zezinye zezinto ezinempembelelo entle kwimfezeko yomqondiso.Le miba ibaluleke kakhulu kwizicelo zokudlulisa idatha ngesantya esiphezulu njenge-USB, HDMI kunye ne-Ethernet ujongano.Ukukwazi ukugcina imfezeko yomqondiso phakathi kokuguquguquka okungokwemvelo kwebhodi kwenza kube lukhetho oluthembekileyo kwiinkqubo zombane ezifunwayo.

Isishwankathelo

Iibhodi zeesekethe eziguquguqukayo zineempawu ezizodwa zombane ezenza zibe zilungele kwiintlobo ezahlukeneyo zezicelo.Ukuguquguquka kwabo kunye nokugoba kubavumela ukuba baqhelane nemilo eyahlukeneyo kwaye bangene kwiindawo eziqinileyo.Ulawulo lwe-impedance luqinisekisa ukuhanjiswa kwesignali echanekileyo, ngelixa i-miniaturization ikhono livumela ukudala izixhobo zombane ezidibeneyo.Ukungcangcazela kunye nokumelana nokothuka, ukumelana nobushushu, kunye nokwandiswa kwemfezeko yesiginali kuphucula ukuthembeka nokusebenza.Ukuqonda iimpawu zombane zeebhodi zeesekethe eziguquguqukayo zibalulekile ekuqondeni amandla abo apheleleyo kunye nokuxhamla iinzuzo zabo kumashishini athile kunye nezicelo.
