Pali zilembo zambiri pa bolodi la PCB, ndiye ndi ntchito ziti zofunika kwambiri munthawi yamtsogolo?Zilembo zodziwika bwino: "R" imayimira kukana, "C" imayimira ma capacitor, "RV" imayimira kukana kosinthika, "L" imayimira inductance, "Q" imayimira triode, "d" ikutanthauza Ndi chubu chachiwiri -board."X kapena Y" amatanthauza kugwedezeka kwa galasi, "U" amatanthauza dera lophatikizika, ndi zina zotero.
Nthawi zambiri, zilembo zina kupatula nambala yaying'ono zimayimira mitundu ina, mitengo yabwino ndi yoyipa, mitundu yamagulu, ndi mabokosi a nyali ndi bokosi la zilembo.Popanga mapangidwe ndi kupanga, muyenera kuganizira zakuthwa kwa khalidwe.Mafotokozedwe a zilembo ndi logo ya chigawocho ndi zomveka bwino, kotero kuti kupanga kungapangitse zilembo zomveka bwino.Pali zilembo zomveka bwino pa bolodi kuti mupewe zolakwika pakuwotcherera ndikukonza kotsatira.
Mapangidwe a zilembo zofananira pa bolodi la PCB
01. Nambala yosindikiza ya silika
Kugwiritsiridwa ntchito kwa manambala osindikizira a silika ndikuphatikiza zigawo zamtsogolo, makamaka zida zopangira pamanja.Nthawi zambiri, chithunzi cha PCB chimagwiritsidwa ntchito poyika zinthu.zofunika.
02. Zizindikiro za Polaris
Kumbuyo kwa magetsi, kutanthauzira kwa polarity ndiko kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.PCB encapsulated khalidwe polar mapangidwe ndi kulabadira zabwino ndi zoipa maelekitirodi.
03. Chizindikiro cha phazi limodzi
Zophatikizika zamagawo ophatikizika nthawi zambiri zimakhala ndi zikhomo zambiri, ndipo logo ya phazi limodzi ndiyo njira yosiyanitsa chipangizocho.Ngati chosindikizira cha silika chosindikizira cha PCB chilibe chizindikiro cha phazi, kapena malo a phazi limodzi ndi zolakwika, zipangitsa kuti chigawocho chimata kulephera kwa anti-product.
Kuwonongeka kwa mawonekedwe pa bolodi la PCB
01. Nambala yaying'ono idaphimbidwa
Makhalidwe omwe ali pachidziwitso chokhudzana ndi chipangizocho angakhalepo kuti zilembozo zatsekedwa kapena zophimbidwa ndi chigawocho.Zidzabweretsa zovuta pakuwotcherera, komanso zidzasokoneza kukonza kotsatira.
02. Nambala yamalo ili kutali kwambiri ndi pad
The pang'ono chiwerengero khalidwe ndi kutali kwambiri ndi chigawo chimodzi, zomwe zidzachititsa lolingana chigawo nambala pamene chigamba anasonkhana, ndipo pangakhale chiopsezo kuwotcherera zomata zigawo zolakwika.
03. Mawu a Pitzer akuphatikizana
Kulumikizana kapena kuphatikizika kwa zilembo zosindikizira za silika kumapangitsa kuti kusindikiza kwa silika kusokonezeke.Posonkhanitsa zigawo, sizingathe kusiyanitsa bolodi yolongedza yomwe ikugwirizana ndi chigawocho.Padzakhala chiopsezo chowotcherera zomata.
