I-PCB engqongqo vs. I-Flexible PCB: Loluphi uhlobo lwePCB olulungele isicelo sakho?

Yazisa:

Ehlabathini lokwenziwa kwebhodi yesekethe, ukukhetha uhlobo oluchanekileyo lwePCB (iBhodi yeSekethe eShicileleyo) kubalulekile kwimpumelelo yeprojekthi yakho yombane. Iinketho ezimbini ezidumileyo ezilawula ishishini ziiPCB eziqinileyo neziguquguqukayo. Uhlobo ngalunye luneenzuzo ezizodwa kunye neengqwalasela ezenza inkqubo yokwenza izigqibo ibe ngumngeni kubantu abaninzi.Kule bhlog, siza kuxoxa ngezinto ezilungileyo kunye nezibi zazo zombini iintlobo zePCB ukukunceda wenze ukhetho olunolwazi. Njengomdlali othembekileyo kwishishini lokuvelisa ibhodi yesekethe, iCapel izisa iminyaka eyi-15 yamava kunye neqela elizinikeleyo leengcali zobugcisa ukukunceda kulo lonke inkqubo yokukhetha.

I. Ukuqonda Rigid PCBs

Ngenxa yokuqina kunye nokungaguquguquki kwendalo, iiPCB eziqinileyo ibe lukhetho lwemveli kwizicelo ezininzi zombane. Zenziwa kusetyenziswa i-substrate eyomeleleyo, eyomeleleyo, edla ngokuqulunqwa nge-fiberglass okanye i-epoxy resin edibeneyo. Nazi ezinye zeempawu eziphambili kunye noncedo lweePCB eziqinileyo:

1. Amandla omatshini: IiPCB eziqinileyo zinamandla omatshini kwaye zilungele izicelo ezifuna uzinzo kunye nenkxaso. Ulwakhiwo lwazo elomeleleyo lubenza bangabi sengozini yomonakalo ovela kumandla angaphandle.

2. Uxinaniso lwecandelo eliphezulu: I-PCB engqongqo yenza ukuba kuxinaniswe kakhulu, nto leyo eluncedo kuyilo oluntsonkothileyo. Olu phawu luluncedo kakhulu kwizixhobo ezifuna inani elikhulu lamacandelo ukuba apakishwe kwindawo encinci.

3. Ukutshatyalaliswa kobushushu: Ngenxa yesakhiwo sayo esomeleleyo, i-PCB eqinile iyakwazi ukutshabalalisa ngokufanelekileyo ubushushu, iqinisekisa ukusebenza kakuhle kunye nokuthembeka naphantsi kwemithwalo eshushu yokushisa.

4. Iindleko-zokusebenza: Ukuveliswa kobunzima beePCB eziqinileyo kaninzi kunciphisa iindleko zeyunithi, kubenze ukhetho loqoqosho kwiiprojekthi ezinkulu ze-elektroniki.

2. Phonononga PCB ebhetyebhetye

IiPCB eziguquguqukayo, njengoko igama libonisa, ziyilelwe ukuba zibe bhetyebhetye kwaye zinokugotshwa okanye zijijwe ukuze zilungele izicelo ezahlukeneyo. Zenziwa kwii-polymer substrates eziguquguqukayo ezifana ne-polyimide okanye i-PEEK (i-polyetheretherketone). Makhe sijonge nzulu kwiingenelo kunye nezilumkiso zePCB ebhetyebhetye:

1. Izithintelo zesithuba: IiPCB eziguquguqukayo zinika ubhetyebhetye lofakelo olungenakuthelekiswa nanto, luzenza zibe lolona khetho lulungileyo lwezixhobo ezixineneyo apho iiPCB zemveli eziqinileyo zinokungangeni. Ukukwazi kwabo ukugoba kuphucula ukusetyenziswa kwendawo kwaye kwandisa amathuba oyilo.

2. Ukunciphisa ubunzima: Xa kuthelekiswa ne-PCB eqinile, i-PCB eguquguqukayo ilula, enenzuzo kakhulu kwizixhobo eziphathekayo ezifuna ukunciphisa ubunzima.

3. Ukuqina: I-PCB eguquguqukayo inokuchasana okuphezulu kwi-vibration, impembelelo kunye nefuthe, kwaye ifanelekile kwizicelo kwiindawo ezinzima okanye kwiindawo ezihamba rhoqo.

4. Iisekethe ezintsonkothileyo: Ezi PCB ziyakwazi ukuphumeza iisekethe ezintsonkothileyo kunye neepatheni zocingo ngenxa yokuguquguquka kwazo, nto leyo ezenza zibe lukhetho lokuqala lwezixhobo zombane eziphambili ezifuna uyilo oluntsonkothileyo.

3.Iizinto ekufuneka ziqwalaselwe xa ukhetha uhlobo lwePCB

Ngoku siphonononge iingenelo zeePCB eziqinileyo nezibhetyebhetye, makhe sixoxe ngezinye zezinto eziphambili ekufuneka siziqwalasele xa ukhetha uhlobo olululo lwePCB:

1. Iimfuno zesicelo: Qonda iimfuno ezithile zeprojekthi yakho. Ukuba uyilo olubambeneyo, intshukumo eguqukayo okanye ulwakhiwo olukhaphukhaphu luyafuneka, iPCB ebhetyebhetye inokuba lolona khetho lungcono. IiPCB eziqinileyo, kwelinye icala, ziyagqwesa kwizicelo ezifuna ingxinano ephezulu yecandelo, uzinzo, kunye namandla oomatshini.

2. Imo engqongileyo kunye neemeko zokusebenza: Vavanya iimeko zokusingqongileyo apho isixhobo sakho sombane sisebenza khona. Ii-PCB eziguquguqukayo zinokubonelela ngokuqina kunye nobomi obude ukuba zibekwe kumaqondo obushushu agqithisileyo, ukungcangcazela okugqithisileyo, okanye ezinye iimeko ezinzima.

3. Iindleko kunye neengqwalasela zokwenziwa: Vavanya iindleko zokwenziwa kunye nokuba nokwenzeka kohlobo ngalunye lwePCB. Ii-PCB eziqinileyo zikholisa ukuba neendleko ezisebenzayo kwimveliso eninzi, ngelixa ii-PCB eziguquguqukayo zinokubandakanya amanyathelo okwenziwa ongezelelweyo kunye nezixhobo ezikhethekileyo, okukhokelela kwiindleko eziphezulu.

4. Uyilo oluntsonkothileyo: Qwalasela ubunzima boyilo lwesekethe. Ukuba iileya ezininzi zibandakanyeka, i-wiring entsonkothileyo iyafuneka, okanye indawo ye-3D kufuneka isetyenziswe, ii-PCB ezibhetyebhetye zinokubonelela ngokuguquguquka koyilo olungcono.

Ukuququmbela:

Ukukhetha uhlobo olululo lwePCB lubalulekile kwimpumelelo yeprojekthi yakho yombane. Ii-PCB eziqinileyo neziguquguqukayo nganye ineengenelo zayo kunye nengqalelo. Ngokuqonda iimpawu ezizodwa zohlobo ngalunye kunye nokuqwalasela izinto ezifana neemfuno zesicelo, iimeko zokusingqongileyo, iindleko kunye nobunzima boyilo, uya kukwazi ukwenza isigqibo esinolwazi. Ngeminyaka eyi-15 ye-Capel yamava okuvelisa ibhodi yesekethe kunye neqela elizinikeleyo leengcali zobugcisa kwicala lakho, unokusithemba ukubonelela ngesikhokelo kunye nenkxaso oyifunayo kuyo yonke inkqubo yokukhetha. Gcina ukhumbule ukuba ukhetho phakathi kwe-PCB eqinile kunye neguquguqukayo ekugqibeleni ixhomekeke kwiimfuno kunye neenjongo zeprojekthi.
