Kukho abalinganiswa abaninzi kwibhodi PCB, ngoko ke yeyiphi imisebenzi ebaluleke kakhulu kwixesha elizayo? Abalinganiswa abaqhelekileyo: "R" imele ukuxhathisa, "C" imele i-capacitors, "i-RV" imele ukuchasana okuhlengahlengiswayo, "L" imele i-inductance, "Q" imele i-triode, "d" ithetha I-tube yesibini-ibhodi. "X okanye Y" uthetha ukungcangcazela kwekristale, "U" uthetha isekethe edibeneyo, njalo njalo.
Ngokubanzi, abanye oonobumba ngaphandle kwe-bit number bamele imifuziselo ethile, iipali ezilungileyo nezingalunganga, imifuziselo yecandelo, kunye neebhokisi zesibane yibhokisi yeempawu. Kwinkqubo yokuyila kunye nokuvelisa, kufuneka uqwalasele ubukhali bomlingiswa. Iimpawu zoyilo lomlinganiswa kunye nelogo yecandelo zicacile, ukwenzela ukuba ukuveliswa kunokuvelisa iimpawu ezicacileyo. Kukho iimpawu ezicacileyo ebhodini ukuphepha amacandelo empazamo ngexesha le-welding kunye nokugcinwa okulandelayo.
Uyilo lweempawu ezifanayo kwibhodi yePCB
01. Inombolo yesilika yokuprinta
Ukusetyenziswa kwamanani oshicilelo lwesilika kukudibanisa icandelo lamva, ngakumbi izinto ezidityanisiweyo zezandla. Ngokubanzi, idiagram yendibano yePCB isetyenziselwa ukubeka izinto kwindawo. kubalulekile.
02. Iimpawu zePolaris
Kwimvelaphi yombane, inkcazo ye-polarity yindlela ehamba ngayo ngoku kwisiphaluka. PCB encapsulated umlinganiswa uyilo polar kukunikela ingqalelo electrode ezintle kunye ezimbi.
03. Ilogo yenyawo enye
Upakisho oludityanisiweyo lwesekethe lunezikhonkwane ezininzi, kwaye uphawu olunonyawo olunye luphawu lokwahlula isixhobo sento. Ukuba iPCB yokupakishwa kwesilika yoshicilelo uphawu ayinayo ilogo yonyawo, okanye indawo yophawu lwenyawo enye ayilunganga, iya kubangela ukuba icandelo lincamathele ukusilela kwemveliso.
Iziphene zoyilo loonobumba kwibhodi yePCB
01. Inombolo encinci igqunyiwe
Oonobumba abakuchongo lwabafowunelwa besixhobo banokubakho ukuba oonobumba bavaliwe okanye bagqunywe lilungu. Kuya kubangela ubunzima kwi-welding ye-asembly, kwaye kuya kubangela ukuphazamiseka ekulungisweni okulandelayo.
02. Inombolo yendawo ikude kakhulu kwipadi
I-bit number character ikude kakhulu necandelo lecandelo, nto leyo eya kubangela ukuba inani lecandelo elihambelanayo lidityaniswe, kwaye kusenokubakho umngcipheko we-welding stickers error components.
03. Igama elithi Pitzer liyadibana
Uqhagamshelwano okanye ukugqithelana koonobumba abahlukeneyo bokuprinta isilika kuya kubangela ukuba ukuprintwa kwesilika kube mfiliba. Xa uhlanganisa amacandelo, ayikwazi ukwahlula ibhodi yokupakisha ehambelana necandelo. Kuya kubakho umngcipheko we-welding stickers.
