I-substrate yebhodi ye-PCB ngokwayo yenziwe ngezinto zokwambathisa kunye nezifudumeza ubushushu ezingekho lula ukugoba. Izinto ezincinci zesekethe ezinokubonwa ngaphezulu ngumfanekiso wobhedu. Ifoyile yobhedu yayigqunywe kwibhodi yonke ye-PCB, kodwa inxenye yayo yagxothwa ngexesha lokuvelisa, kwaye inxalenye eseleyo yaba ngumnatha weesekethe ezincinci ze-NS. Le migca ibizwa ngokuba ziingcingo okanye ii-wiring, kwaye zisetyenziselwa ukubonelela ngonxibelelwano lweesekethe kumalungu akwi PCB.

Ngokwesiqhelo umbala webhodi ye-PCB iluhlaza okanye imdaka, umbala we-solder mask. Sisikhuselo esikhuselayo esikhuselayo esinokukhusela ucingo lobhedu kwaye sithintele iindawo ukuba zingadityaniswa kwindawo engeyiyo. Iibhodi ze-multilayer ngoku zisetyenziselwa iibhodi ze-mama kunye namakhadi emizobo, eyonyusa kakhulu indawo enokuthi ifakwe ngeentambo.

Ulihlula njani inani lamanqanaba ebhodi ye-PCB yebhodi yomama
Amanyathelo / Iindlela
Iibhodi ze-multilayer zisebenzisa iibhodi ezizezinye okanye ezingamacala amabini, kwaye zibeke umaleko wokugquma umaleko phakathi kohlu ngalunye lweebhodi kwaye uzicinezele kunye.

Inani lemiqolo yebhodi PCB kuthetha ukuba kukho iileya ezininzi ezimeleyo kweentambo. Ngokwesiqhelo inani lamanqanaba alinganayo kwaye liqulathe la manqanaba mabini angaphandle. Iibhodi ze-PCB eziqhelekileyo zinesakhiwo esiyi-4 ukuya kwezi-8. Inani leengqimba zeebhodi ezininzi zePBB liyabonakala ngokujonga umphezulu webhodi yePCB. Kodwa enyanisweni, akukho mntu unokubona kakuhle kangako. Ke, mandikufundise enye indlela engezantsi.

Unxibelelwano lweesekethe lwebhodi enemaleko emininzi kungcwatywa ngeemfama ngetekhnoloji. Uninzi lweebhodi zee-mama kunye namakhadi okubonisa asebenzisa ungqimba lwe-4 PCB iibhodi, kwaye ezinye zisebenzisa i-6, 8-layer, okanye 10-layer PCB boards.

Ukuba ufuna ukubona ukuba zingaphi iilebhile zePCB, unokuyichonga ngokujonga imingxunya, kuba iibhodi zemigca emi-4 esetyenziswe kwibhodi yomama kunye nekhadi lokubonisa ziluhlu kumaleko wokuqala nowesine, kwaye amanye amacwecwe anezinye isebenzisa (iingcingo zomhlaba). Kunye nonikezelo lwamandla). Ke ngoko, njengebhodi enemaleko ephindiweyo, umngxuma uya kungena PCB ibhodi.

Ukuba ezinye ii-vias zivela ngaphambili kwi-PCB kodwa azifumaneki kwi-reverse, ke kufuneka ibe yibhodi engqonge i-6/8. Ukuba okufanayo ngemingxunya kunokufumaneka kumacala omabini e-PCB, iya kuba yibhodi enemigca emi-4.
