Kwinkqubo yemveliso ye-PCB, ikho enye inkqubo ebalulekileyo, oko kukuthi, umtya wokuthoba. Ukugcinwa komda wenkqubo kubaluleke kakhulu ekusebenzeni kwe-PMT.
Umtya wokuthoba isixhobo senxalenye yongezwa kumacala omabini okanye amacala amane kwibhodi ye-PCB, ikakhulu ukuncedisa iplagi ye-SMT ukweza kwiBhodi ye-SMT SMT ikhupha umatshini we-PCB kwaye ungene kumatshini we-SMT SMT. Ukuba izinto zikufuphi kakhulu kwi-track emphethweni ekufunxa izixhobo kwi-SMT SMT MAHLE kwaye inamathele kwiBhodi yePCB, i-phenomenon yengqungquthela inokwenzeka. Ngenxa yoko, imveliso ayinakugqitywa, ngoko ke umtya wesixhobo esithile kufuneka ugcinelwe, ububanzi ngokubanzi be-2-5mm. Le ndlela ikwafanelekile kwezinye izinto zeplagi, emva kokuthengiswa kwetyala ukuthintela i-phenomena efanayo.
Umtya wokuthoba isixhobo asiyonxalenye yeBhodi yePCB kwaye inokususwa emva kwemveliso yePCBA igqityiwe

Indlela yeVeza umtya wokuthoba:
1, V-Spit: Unxibelelwano lwenkqubo phakathi komtya wokuthoba kunye neBhodi, ukunqunyulwa kancinci kumacala omabini ebhodi yePCB, kodwa kungasiki!
2, Sebenzisa imivalo: Sebenzisa imivalo emininzi ukudibanisa ibhodi ye-PCB, yenza imingxunya ye-stamp embindini, ukuze isandla siphulwe okanye sihlanjwe ngumatshini.

Ayizizo zonke iibhodi ze-PCB ezidinga ukongeza umtya wokusebenzisa, ukuba i-PCB yeBhodi ye-PCB inkulu, ishiye amacandelo omabini e-5mm kumacala athile kwi-5mm kwelinye le-5mm kwi-5mm kwelinye icala. Oku kudinga ingqalelo yenjineli ye-PCB.

IBhodi ityhutywe ngumtya wokukratya, iya konyusa iindleko ze-PCB, ke kufuneka ikwazi ukulinganisa uqoqosho kunye nezakhiwo xa ziyilotha i-PCB.
 
Kwibhodi ethile ye-PCB ekhethekileyo, ibhodi ye-PCB enemigca yesi-2 okanye emi-4 ye-4 inokubekwa lula ngokudibanisa iBhodi.
 
Kwinkqubo ye-SMT, uyilo lwemodi yokuPhakamisa kufuneka ithathe iakhawunti epheleleyo yobubanzi be-SMT ye-SMT. Kwibhodi ye-pirimed enobubanzi obungaphezulu kwe-350mm, kufuneka ukuba unxibelelane nenjineli yenkqubo yomthengisi weSMT.
