Ingabe i-PCB iqedile uma isakhiwo siqedwa futhi azikho izinkinga ezitholakala ngokuxhumanisakanye nesikhala?
Yebo, impendulo ingucha. Abaningi abasaqalayo, ngisho nonjiniyela abanolwazi, ngenxa yesikhathi esilinganiselwe noma ukuphelelwa isineke noma ukuzethemba kakhulu,
kuvame ukushesha, ukuziba ukuhlola sekwephuzile, kube nezimbungulu zezinga eliphansi kakhulu, njengokuthi ububanzi bomugqa akwanele, ukuphrinta kwelebula
ingcindezi nezimbobo zokuphuma zisondele kakhulu, amasignali kuluphu, njll., aholela ezinkingeni zikagesi noma zenqubo, ukudlala ibhodi okubucayi, ukumosha. Ngakho-ke,
ukuhlolwa kwangemuva kuyisinyathelo esibalulekile ngemuva kokuthi i-PCB isibekiwe.
1. Ukupakishwa kwengxenye
(1) Isikhala sephedi. Uma kuyidivayisi entsha, ukudweba iphakheji yabo yezingxenye, qinisekisa ukuthi isikhala sifanelekile. Isikhala sephedi sithinta ngqo ukushisela kwezingxenye.
(2) Ngosayizi (uma ukhona). Kumadivayisi e-plug-in, usayizi wembobo kufanele ugcinwe umkhawulo owanele, ngokuvamile hhayi ngaphansi kuka-0.2mm ofaneleka kakhulu.
(3) Uhlaka lwesikrini sikasilika. Ukuphrinta kwesikrini se-contour sezingxenye kufanele kube
nkulu kunosayizi wangempela ukuqinisekisa ukuthi idivayisi ingafakwa kahle.
2. Isakhiwo
(1) I-IC akufanele ibe eduze konqenqema lwebhodi.
(2) Izingxenye zesekethe kumojula efanayo kufanele zibekwe eduze komunye nomunye. Isibonelo, i-decoupling capacitor kufanele ibe
eduze kwephinikhodi yokuphakela amandla ye-IC, futhi izingxenye ezakha isekethe efanayo yokusebenza kufanele zibekwe endaweni efanayo ngohlelo olucacile.
ukuqinisekisa ukufezeka kwemisebenzi.
(3) Hlela indawo yesokhethi ngokusho kokufakwa kwangempela. I-Socket ixhunywe kwamanye amamojula ngokuhola, ngokusho kwesakhiwo sangempela,
ukuze ufake kalula, ngokuvamile sebenzisa indawo yesokhethi yesimiso esiseduze, futhi ngokuvamile eduze konqenqema lwebhodi.
(4) Naka indlela yokuphuma. Isokhethi idinga isiqondiso, uma isiqondiso siphambene, ucingo ludinga ukwenziwa. Ngesokhethi eyisicaba, ukuma kwesokhethi kufanele kube ngaphandle kwebhodi.
(5) Akufanele kube khona izinsimbi endaweni yokugcina ngaphandle.
(6) Umthombo wokuphazamiseka kufanele ube kude nesekethe ebucayi. Isignali yesivinini esikhulu, iwashi lesivinini esiphezulu noma isignali yokushintsha yamanje ephezulu imithombo yokuphazamiseka, kufanele ibe kude nesekhethi ebucayi (efana nokusetha kabusha isekethe, isekethe ye-analog). Angahlukaniswa yiphansi.
