Kodi ma PCB osasunthika amalimbana ndi chinyezi?

Zikafika pakukana chinyezi komanso kukana chinyezi, wina angadabwe ngati ma PCB okhazikika amatha kuthana ndi vutoli. Mu positi iyi yabulogu, tizama mozama pamutuwu ndikuwona kukana chinyezi ndi chinyezi cha ma PCB okhazikika.
Ma board adera osindikizidwa (PCBs) ndiye maziko a zida zamakono zamakono, zomwe zimapereka nsanja yolumikizira ndikuthandizira zida zosiyanasiyana zamagetsi. Ukadaulo wa PCB wasintha kwazaka zambiri, ndipo chimodzi mwazotukukazi chakhala kukhazikitsidwa kwa ma PCBs okhazikika.Ma board awa amapereka kusinthasintha kuphatikiza ndi kukhulupirika kwa matabwa okhwima, kuwapanga kukhala osunthika kwambiri komanso oyenera kugwiritsa ntchito mitundu yosiyanasiyana.

Chinyezi ndi chinyezi ndizofala zachilengedwe zomwe zingakhudze kwambiri magwiridwe antchito ndi kudalirika kwa zida zamagetsi.Kuwonetsa chinyezi kungayambitse mavuto osiyanasiyana, kuphatikizapo dzimbiri, akabudula amagetsi, ndi kuwonongeka kwa kusungunula.Chifukwa chake, ndikofunikira kuwonetsetsa kuti ma PCB omwe amagwiritsidwa ntchito pazida amalimbana ndi izi, makamaka pamapulogalamu omwe amawoneka ndi chinyezi chambiri.

Rigid-flex PCB ili ndi mawonekedwe apadera ndipo imakhala ndi kuchuluka kwa chinyezi komanso kukana chinyezi.Ma board awa amapangidwa kuchokera kumagulu osinthika a polyimide ndi zigawo zolimba za FR-4, ndikupanga bolodi lolimba komanso lodalirika. Chosanjikiza cha polyimide chimapereka kusinthasintha, kulola PCB kupindika kapena kupindika ngati pakufunika, pomwe gawo la FR-4 limapereka kukhazikika kwadongosolo.

Chimodzi mwazinthu zazikulu zomwe zimathandizira kukana kwa ma PCB osasunthika ku chinyezi ndi chinyezi ndikugwiritsa ntchito polyimide monga maziko a zinthu.Katunduyu amateteza kukhulupirika kwa PCB poletsa kusanjikiza kwa polyimide kuti asatengere chinyezi.Kuonjezera apo, kusinthasintha kwa polyimide kumapangitsa kuti matabwa ozungulira azitha kupirira zinthu zina zachilengedwe popanda kukhudzidwa ndi chinyezi.

Kuphatikiza apo, bolodi lolimba-flex amapangidwa pogwiritsa ntchito ukadaulo wapamwamba kuti apititse patsogolo mphamvu zake zoteteza chinyezi komanso chinyezi.Njirazi zimaphatikizapo kugwiritsa ntchito zokutira zodzitchinjiriza, monga zokutira zodzitchinjiriza kapena zosindikizira, zomwe zimakhala ngati chotchinga chotchinga chinyezi. Zopaka izi zimapangidwira kuti chinyontho chisafike pazida zamagetsi zomwe zimawonongeka ndikuwononga.

Ndizofunikira kudziwa kuti ngakhale ma PCB olimba-flex ali ndi chinyezi chachikulu komanso kukana chinyezi, satetezedwa kwathunthu kuzinthu izi.Zovuta kwambiri, kukhudzidwa kwanthawi yayitali ku chinyezi chambiri, kapena kusagwira bwino kungakhudzebe magwiridwe antchito a ma board.Chifukwa chake, zofunikira zenizeni za chilengedwe cha pulogalamu inayake ziyenera kuganiziridwa ndipo PCB idapangidwa moyenerera.

Popanga kukana chinyezi kwa ma PCB olimba-flex, zinthu zingapo ziyenera kuganiziridwa.Kutalikirana kokwanira pakati pa zigawo, kusindikiza koyenera kwa zolumikizira ndi ma vias, komanso kugwiritsa ntchito mwanzeru zinthu zotsimikizira chinyezi ndi zina mwazinthu zazikulu zomwe zimathandiza kukulitsa kukana kwa PCB kuzinthu zachilengedwe izi.Kugwira ntchito limodzi ndi wopanga PCB wodziwa bwino kungathe kuwonetsetsa kuti kapangidwe kake kakukometsedwa. kukwaniritsa mlingo wofunikira wa chinyezi ndi kukana chinyezi.

Mwachidule, chifukwa cha mawonekedwe ake apadera komanso kugwiritsa ntchito zinthu zoteteza chinyezi monga polyimide, matabwa olimba osinthasintha nthawi zambiri amakhala ndi zinthu zabwino zoteteza chinyezi komanso zoteteza chinyezi.Amapereka njira yodalirika pazida zamagetsi zomwe zitha kukumana ndi zovuta zachilengedwe. Komabe, m'pofunika kuganizira zofunika zenizeni za ntchito ndi kupanga PCB moyenerera kukulitsa luso lake kupirira chinyezi ndi chinyezi. Pochita izi, opanga zida zamagetsi amatha kutsimikizira moyo wautali komanso kudalirika kwazinthu zawo, ngakhale m'malo ovuta.
