I-PCB enezinhlangothi ezimbili ezijwayelekile abakhiqizi be-Countersink | YMSPCB

Ephrintiwe Yesifunda IBhodi Isingeniso

A Ibhodi lesifunda mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.PCBs can be single-sided (one copper layer), double-sided (two copper layers on both sides of one substrate layer), or multi-layer (outer and inner layers of copper, alternating with layers of substrate). Multi-layer PCBs allow for much higher component density, because circuit traces on the inner layers would otherwise take up surface space between components. The rise in popularity of multilayer PCBs with more than two, and especially with more than four, copper planes was concurrent with the adoption of surface mount technology.

Amabhodi wesekethe anezinhlangothi ezimbili ayinkimbinkimbi kancane kune-PCB yohlangothi olulodwa. Lawa mabhodi aqukethe ungqimba olulodwa nje lwe-base substrate. Nokho, aqukethe izendlalelo conductive ohlangothini ngalunye. Basebenzisa ithusi njengento eqhubayo. Masingene sijule ngaphakathi kwe-PCB ezinhlangothi zombili ukuze sifunde kabanzi!

Isakhiwo Nezinto Zokusebenza Ze-Double Sided PCB

Impahla ye-PCB enezinhlangothi ezimbili ingahluka ngesisekelo sohlobo lwephrojekthi. Nokho, izinto eziwumgogodla zicishe zifane kuwo wonke amabhodi wesifunda. Nokho, ukwakheka kwe-PCB kuyahlukahluka kuye ngohlobo.

I-Substrate: Kuyinto ebaluleke kakhulu eyenziwe nge-fiberglass. Ungakuthatha njengohlaka lwamathambo e-PCB.

Ungqimba Lwethusi: Kungaba yi-foil noma i-copper coating egcwele. Yingakho kuncike ohlotsheni lwebhodi. Umphumela uyafana noma ngabe usebenzisa i-foil noma i-copper coating. Amabhodi wesifunda anezinhlangothi ezimbili aqukethe ungqimba lwethusi oluqhutshwayo nhlangothi zombili.

I-Solder Mask: Ingqimba evikelayo ye-polymer. Ngakho-ke, ivimbela ithusi kusuka ku-short-circuiting. Ungayibheka njengesikhumba sebhodi lesifunda. Ukusoda kwe-PCB ezinhlangothini ezimbili kuyisinyathelo esibaluleke kakhulu sokuqina.

Isikrini sikasilika: ingxenye yokugcina yesikrini sikasilika. Nakuba ingenayo indima ekusebenzeni kwebhodi lesifunda. Abakhiqizi bayisebenzisela ukukhombisa izingxenye zezinombolo. Izingxenye zezinombolo zibaluleke kakhulu ngezinjongo zokuhlola. Ngaphezu kwalokho, ungaphrinta amalogo enkampani yakho noma olunye ulwazi ngendlela yombhalo.

Ubuhle kanye Nobubi Bamabhodi Esifunda Anezinhlangothi Ezimbili

Nazi ezinye izingcweti nezimbi zamabhodi esekethe aphrintwe kabili:

Izinzuzo zamabhodi esekethe anamacala amabili

Ikhwalithi Ephakeme: Ukuhlela nokuklama le PCB kudinga inani elihle lomsebenzi. Okuholela kumabhodi esekethe ekhwalithi ephezulu.

Isikhala Esanele Sezingxenye: Sigcina isikhala esengeziwe sezingxenye. Ngoba izinhlangothi zombili zongqimba ziyi-conductive.

Izinketho Eziningi Zokuklama: Inezingqimba eziqhutshwayo nhlangothi zombili. Ungakwazi ukunamathisela izingxenye ze-electronic ezahlukene nhlangothi zombili. Ngakho unezinketho eziningi zokuklama.

I-Sourcing and Sinking Current: Ngenkathi uyisebenzisa njengesendlalelo esingezansi, ungayisebenzisela ukucwila kanye nokukhipha okwamanje.

Ukusetshenziswa: Ngenxa yokusebenza kahle kwayo, ungayisebenzisa ezinhlelweni eziningi.

Ukungalungi kwamabhodi eSekethe anezinhlangothi ezimbili

Izindleko Eziphakeme: Ukwenza izinhlangothi zombili zisebenze, kuza ngezindleko eziphakeme kancane.

Kudingeka Umklami Onekhono: Kufaka phakathi inqubo yokukhiqiza ye-PCB enezinhlangothi ezimbili enzima ukuze yakheke. Ngakho-ke, udinga onjiniyela abachwepheshile ngemikhiqizo yayo.

Isikhathi Sokukhiqiza: Isikhathi sokukhiqiza singaphezu kwe-PCB eseceleni olulodwa ngenxa yobunkimbinkimbi bayo.

Ukusetshenziswa Kwamabhodi Esifunda Anezinhlangothi Ezimbili

Lolu hlobo lwebhodi lesifunda lukhulisa ukuminyana kwesifunda. Ziyakwazi nezimo kakhulu futhi. Cishe bonke abakhiqizi be-PCB ezinhlangothi zombili bayisebenzisa kumagajethi amaningi kagesi. Ngezansi kunesimo esimangalisayo sokusetshenziswa kwamabhodi esekethe anezinhlangothi ezimbili:

I-HVAC kanye nokukhanyisa kwe-LED

Uhlelo lokulawula ithrafikhi

Amadeshibhodi ezimoto

Lawula ukudluliselwa kanye nokuguqulwa kwamandla

Izilawuli nezinto zikagesi

Ukuhlola nokuqapha imishini ehlukene

Amaphrinta namasistimu omakhalekhukhwini

Imishini yokuthengisa.
