Zeziphi izinto ezingeloncedo kwi-PCB eqinileyo? Uhlalutyo olunzulu

Iibhodi zesekethe eziprintiweyo (PCBs) ziyinxalenye yethekhinoloji yanamhlanje. Usetyenziso lwabo lusuka kwii-smartphones kunye neekhompyuter ukuya kwizixhobo zonyango kunye neenkqubo zeemoto. Kukho iintlobo ezahlukeneyo zePCB, enye yazo i-PCB eqinile. Ngelixa ii-PCB eziqinileyo zibonelela ngeengenelo ezininzi, zikwanazo nezingeloncedo zazo.Kule post yebhlog, siza kuphonononga izinto ezingeloncedo kwiiPCB eziqinileyo kwaye sijonge izizathu ezisemva kwazo.

1. Ububhetyebhetye obulinganiselweyo:

Eyona nto ingalunganga ye-PCBs engqongqo kukuguquguquka okulinganiselweyo. Njengoko igama libonisa, ii-PCB eziqinileyo azikwazi ukuguquguquka kwaye azikwazi ukugoba okanye ukugoba. Kwezinye izicelo, oku kungabikho kokuguquguquka kunokuba yintsilelo ebalulekileyo. Umzekelo, kwitekhnoloji enxitywayo okanye izixhobo ezifuna ukuhamba rhoqo, iiPCB eziqinileyo zinokunciphisa uyilo kunye nokusebenza. Olu thintelo lunokuthi luthintele uphuhliso lwezixhobo ze-elektroniki eziqalwayo.

2. Imingeni yokonga indawo:

IiPCB ezingqongqo azigcini nje ngokugcina isithuba njengezinye iintlobo zeePCB. Ekubeni zingenako ukugoba okanye ukubunjwa, zifuna indawo engaphezulu, ekugqibeleni zichaphazela ukucwangciswa ngokubanzi kunye noyilo lweemveliso zombane. Lo mda ubaluleke kakhulu kwizixhobo ezincinci okanye izixhobo ezineesekethe eziyinkimbinkimbi, apho i-millimeter nganye yendawo ibala. Abaqulunqi bahlala kufuneka basebenze malunga nale mida, okukhokelela ekuthotyweni ekusebenzeni ngokubanzi okanye ukwanda kobukhulu bemveliso yokugqibela.

3. Iingcingo ezintsonkothileyo kunye nendibano:

IiPCB eziqinileyo zifuna iingcingo ezintsonkothileyo kunye nendibano kuneePCB ezibhetyebhetye. Ubume obuqinileyo bezi bhodi buthetha ukuba imikhondo yeesekethe kufuneka ihanjiswe kwimiphetho emiselweyo. Oku kwenza uyilo lwe-PCB lube nzima ngakumbi kwaye ludle ixesha, okukhokelela ekunyukeni kweendleko zemveliso. Ukongezelela, ukungakwazi ukugoba ibhodi kwenza kube nzima ukulungiselela amacandelo athile okanye iziqhagamshelo, ngakumbi ukudibanisa inkqubo yendibano.

4. Uchaphazeleka kuxinzelelo lomatshini:

IiPCB eziqinileyo zichaphazeleka ngakumbi kuxinzelelo lomatshini kunePCB ezibhetyebhetye. Ukungakwazi ukufunxa ukothuka okanye ukungcangcazela, zonakaliswa ngokulula, ngakumbi kwizicelo ezibandakanya intshukumo rhoqo okanye iimeko zokusingqongileyo. Ukuqina kwe-PCB kunokubangela ukuba amalungu e-solder angaphumeleli, okubangela iingxaki zoqhagamshelwano kunye nokubeka esichengeni ukuthembeka kwesekethe. Oku kungasebenzi kufuneka kuqwalaselwe ngononophelo xa ukhetha uhlobo lwePCB kwisicelo esithile.

5. Iindleko eziphezulu:

IiPCB eziqinileyo zidla ngokubiza kakhulu xa kuthelekiswa neePCB ezibhetyebhetye. Iinkqubo zokuvelisa ezintsonkothileyo, iiplani ezintsonkothileyo kunye neendleko eziphezulu zemathiriyeli zikhokelela kumaxabiso aphezulu. Oku kunokuba yingxaki enkulu kwiiprojekthi ezikuhlahlo lwabiwo-mali oluqinisiweyo okanye kwiimveliso apho iindleko ziqwalaselwa kakhulu. Nangona kunjalo, kubalulekile ukuba uqaphele ukuba iimfuno ezithile zeprojekthi kufuneka zihlale zikhokela inkqubo yokukhetha, ngokuqwalasela zonke izinto, kubandakanywa neendleko ezifanelekileyo.

Isishwankathelo

Ngelixa ii-PCB eziqinileyo zineengenelo malunga nokuqina kolwakhiwo kunye nokuzinza, nazo zineengxaki ezithile.Ukuguquguquka okulinganiselweyo, imingeni yokugcina indawo, umzila onzima kunye nokuhlanganisana, uvakalelo kuxinzelelo lomatshini, kunye neendleko eziphezulu zizinto zonke ekufuneka ziqwalaselwe xa ukhetha uhlobo lwe-PCB kwisicelo esithile. Yonke iprojekthi yoyilo ifuna ukuphononongwa ngononophelo kwezibonelelo kunye neengxaki, ukugcina iimfuno ezithile kunye nemiqobo engqondweni. Eyona njongo iphambili kukufumana olona hlobo lufanelekileyo lwePCB ukuqinisekisa ukusebenza kakuhle, ukusebenza kunye nokuphumelela kweendleko kwisicelo esinikiweyo.
