Ingaba i-1oz yobhedu iJikele kangakanani?

Kwishishini lebhodi yesekethe eprintiweyo, eyona ndlela ixhaphakileyo yokubonisa ubukhulu bobhedu kwi- PCB ngama-ounces (oz). Kutheni usebenzisa iyunithi yobunzima ukucacisa ubukhulu? Umbuzo omkhulu! Ukuba i-1oz (28.35 grams) yobhedu ithe tyaba ukuze igubungele ngokulinganayo i-square foot of surface (0.093 square metre), ubuninzi besiphumo buya kuba yi-1.37mils (0.0348mm). Itshathi yoguqulo yeeyunithi ezahlukeneyo zomlinganiselo inokufumaneka ngezantsi.

Ndidinga iCopper engakanani?

Ngomda obanzi, iiPCB ezininzi zenziwe nge-1oz yobhedu kumaleko ngamnye. Ukuba iifayile zakho azibandakanyi ushicilelo lwefab okanye ezinye iinkcukacha, siyakuthatha i-1oz egqibile ubunzima bobhedu kuzo zonke iileya zobhedu. Ukuba uyilo lwakho lufuna i-voltages ephezulu, ukuxhathisa, okanye i-impedances, ubhedu obunzima bunokuba yimfuneko. Kukho izixhobo ezininzi ze-intanethi ezinokukunceda ukuba uqonde ukuba bubuphi na ubukhulu, ububanzi okanye ubude bomkhondo ofunekayo ukuze ufezekise iziphumo ojolise kuzo. Izixhobo ezimbalwa ezinjalo zeqela lesithathu zidityaniswe ngezantsi. I-PCB Prime ayinxulumananga nababhali bezi zixhobo.

 

Ukusasazwa kobhedu

Njengomgaqo jikelele, ubhedu kufuneka lusasazwe ngokulinganayo ngokunokwenzeka kulo lonke uyilo lwakho. Ayipheleli nje ngokubhekisele kubunzima bobhedu kumaleko ngamnye, kodwa nendlela esasazwa ngayo kumaleko. Ewe, oku akusoloko kusenzeka, kodwa gcina oku engqondweni ngexesha loyilo.

I-Plating kunye ne-etching ziinkqubo eziphilayo ngengqiqo yokuba i-laminate ye-copper clad ifakwe kwi-vat yeekhemikhali ukuze zilungiswe. Alukho ulawulo oluchanekileyo apho ubhedu lukhutshwa okanye lubekwe kulo. Ngexesha le-etch, umfanekiso ocetywayo uyagqunywa ukuze ukhuseleke kwi-etchant, kodwa iikhemikhali ezisetankini zinyibilikisa ubhedu ngemilinganiselo eyahlukileyo kancinane ngokuxhomekeke ekubeni ziphi na iimpawu zephaneli, ukubekwa kwephaneli ngaphakathi kwetanki ngokwayo, kunye nendlela exinene ngayo. okanye ngokunqabileyo iimpawu zobhedu zisasazwa.

Isisombululo sekhemikhali kwi-plating kunye ne-etching tanks iyaphazamiseka kwaye ijikelezwe ngexesha lokucubungula ukunciphisa oku kungahambelani; nangona kunjalo, indawo yolawulo enokuxinana kobhedu okwahlukileyo kakhulu kunokuba yingxaki. Ngexesha loyilo lwakho, zama ukusasaza ngokulinganayo ubhedu lwakho kuyo yonke ibhodi kunokuba ube neendawo ezinkulu ezivulekileyo ezineempawu ezizimeleyo.

INDLELA YOKUKHETHA I-PCB EFANELEKILEYO UBUTYEFU BOKOPHA

Ukukhetha ubukhulu bobhedu obunzima obufanelekileyo ukuba bufakwe kwi-plaled ngokusebenzisa umngxuma (PTH) idlala into ebalulekileyo ekuthembekeni okupheleleyo kwebhodi yesekethe eprintiweyo. Kukho izinto ezimbini ezingundoqo ekufuneka ziqwalaselwe xa kumiselwa ubukhulu bePCB yobhedu. Eyokuqala ngumthamo wangoku wombhobho wokunyuka kobushushu okwamkelekileyo. Okwesibini ngamandla oomatshini amiselwe ubukhulu bobhedu, ubungakanani bomngxuma kunye nokuba kukho nayiphi na inkxaso nge-vias.

Uninzi lwabathengi bafuna ukwakha iiPCBs kunye nokusebenza okugqwesileyo ngexabiso lezoqoqosho. Inyathelo lokuqala kukukhetha ukutyeba kobhedu olufanelekileyo kudidi lwakho lwePCB. Iimpawu ezizodwa zobu bunzima zibalulekile ekumiseleni imisebenzi, ukusebenza kwee-PCBs. Ukuba ungathanda ulwazi oluthe kratya malunga nokukhetha ubukhulu bobhedu lwe-PCB okanye indlela yokukhetha eyona ilungileyo uyilo lwePCB yakho, nceda uqhagamshelane nathi. Asinikezeli nje iingcebiso ezilungileyo kodwa isisombululo esipheleleyo. Uya kufumana iiPCB ezincinci kunye nezikrelekrele ngokusebenza okugqwesileyo kunye nokuthembeka okuphezulu kwi-YMS.
