Akukho mathandabuzo ukuba ibhodi yesekethe eprintiweyo (PCB) sisixhobo esibalulekileyo kubuchwepheshe babantu.

IiPCB ziye zaba yindlela yokuphucula inkqubo yokuvelisa izixhobo zombane.Ngaphambili, ezi zixhobo ze-elektroniki zakhiwe ngesandla kwafuneka zitshintshwe ngeebhodi zesekethe eziprintiweyo.Oku kungenxa yokuba imisebenzi emininzi iya kudityaniswa ebhodini.

Thelekisa ibhodi yesekethe yesibali-manani sika-1968 kunye nebhodi yomama yekhompyuter yanamhlanje.

1. Umbala.

Nakwabanye abantu abangaziyo ukuba yeyantoni na iPCB, badla ngokuyazi ukuba injani na iPCB.Ubuncinane bakhangeleka ngathi banesitayile semveli esinye, esiluhlaza.Lo mbala uluhlaza ngokwenyani ngumbala ocacileyo wepeyinti yeglasi ye-solder.Nangona igama lemaski ye-solder imaski ye-solder, umsebenzi wayo ophambili kukukhusela isiphaluka esigqunyiweyo kumswakama kunye nothuli.

Ngokuphathelele kutheni imaski ye-solder iluhlaza, esona sizathu kukuba uhlaza ngumgangatho wokhuselo lomkhosi.Okokuqala, ii-PCB kwizixhobo zomkhosi zisebenzise iimaski ze-solder endle ukukhusela ukuthembeka kwesekethe.

Iimaski zeSolder ngoku ziyafumaneka ngemibala eyahlukeneyo, kubandakanya emnyama, ebomvu, emthubi, kunye nokunye.Emva kwayo yonke loo nto, uhlaza alukho umgangatho woshishino.

2. Ngubani owasungula iPCB?

Iibhodi zesekethe eziprintiweyo zokuqala zinokulandelwa kwinjineli yase-Austrian uCharles Ducas ngo-1920, owacebisa ingcamango yokuqhuba umbane nge-inki (ukushicilela iingcingo zobhedu kwi-plate ephantsi).Wasebenzisa ubuchwepheshe be-electroplating ukwenza iingcingo ngokuthe ngqo kumphezulu we-insulator kwaye wenza iprototype ye-PCB.

Iingcingo zetsimbi kwiibhodi zeesekethe zaqala ubhedu, i-alloy yobhedu kunye ne-zinc.Olu qulunqo oluphazamisayo luphelisa inkqubo yocingo olunzima lweesekethe ze-elektroniki, ukuqinisekisa ukuthembeka kokusebenza kweesekethe.Le nkqubo ayizange ingene kwinqanaba lesicelo esisebenzayo de kube sekupheleni kweMfazwe Yehlabathi II.

3. Phawula.

Kukho amanqaku amaninzi amhlophe kwibhodi yesekethe eluhlaza.Kangangeminyaka, abantu bebengasiqondi isizathu sokuba ezi printing zimhlophe zibizwe ngokuba “zii-silkscreen layers”.Zisetyenziselwa ikakhulu ukuchonga ulwazi lwecandelo kwibhodi yesekethe kunye nezinye iziqulatho ezinxulumene nebhodi yesekethe.Olu lwazi lunokunceda iinjineli zeesekethe zijonge ibhodi ngeempazamo.
