Chofufuzira cha PCB ndi njira yolumikizirana yoyesera zamagetsi, yomwe ndi gawo lofunikira lamagetsi komanso chonyamulira cholumikizira ndi kuyendetsa zida zamagetsi. Chofufuzira cha PCB chimagwiritsidwa ntchito kwambiri kuyesa kutumiza deta ndi kulumikizana kwa PCBA. Deta ya ntchito yolumikizira ma conductive ya chofufuzira ingagwiritsidwe ntchito kuweruza ngati chinthucho chili bwino komanso ngati deta yogwirira ntchito ndi yabwinobwino.
Kawirikawiri, chipangizo chofufuzira cha PCB chili ndi zinthu zambiri zofunika, makamaka zomwe zimakhala ndi magawo atatu: choyamba, chubu cha singano, chomwe chimapangidwa makamaka ndi aloyi wamkuwa ndipo chimakutidwa ndi golide. Chachiwiri ndi kasupe, makamaka waya wachitsulo wa piyano ndipo chitsulo cha sikani chimakutidwa ndi golide. Chachitatu ndi chipangizo chofufuzira singano, makamaka chitsulo cha zida (SK) nickel kapena golide. Zigawo zitatu zomwe zili pamwambapa zimasonkhanitsidwa mu chipangizo chofufuzira. Kuphatikiza apo, pali chikwama chakunja, chomwe chingalumikizidwe ndi kuwotcherera.
Mtundu wa PCB probe
1. Kafukufuku wa ICT
Malo omwe amagwiritsidwa ntchito kwambiri ndi 1.27mm, 1.91MM, 2.54mm. Magulu omwe amagwiritsidwa ntchito kwambiri ndi 100 series, 75 series, ndi 50 series. Amagwiritsidwa ntchito makamaka poyesa ma circuit pa intaneti komanso poyesa magwiridwe antchito. Kuyesa kwa ICT ndi mayeso a FCT amagwiritsidwa ntchito pafupipafupi poyesa ma PCB board opanda kanthu.
2. Chofufuzira chokhala ndi mbali ziwiri
Imagwiritsidwa ntchito poyesa BGA. Ndi yolimba kwambiri ndipo imafuna luso lapamwamba. Nthawi zambiri, ma chip a IC a foni yam'manja, ma chip a IC a laputopu, makompyuta a mapiritsi ndi ma chip a IC olumikizirana amayesedwa. Kukula kwa thupi la singano kuli pakati pa 0.25MM ndi 0.58MM.
3. Chofufuzira chosinthira
Chofufuzira cha switch imodzi chili ndi ma circuit awiri a current kuti azilamulira ntchito ya circuit yomwe nthawi zambiri imatsegulidwa komanso nthawi zambiri imatsekedwa.
4. Chofufuzira cha pafupipafupi kwambiri
Imagwiritsidwa ntchito poyesa zizindikiro zama frequency apamwamba, ndi mphete yotchingira, imatha kuyesedwa mkati mwa 10GHz ndi 500MHz popanda mphete yotchingira.
5. Chofufuzira chozungulira
Kutanuka kwake nthawi zambiri sikokwera kwambiri, chifukwa kulowerera kwake kumakhala kolimba mwachibadwa, ndipo nthawi zambiri kumagwiritsidwa ntchito poyesa PCBA komwe kwakonzedwa ndi OSP.
6. Chofufuzira champhamvu kwambiri
Chidutswa cha probe chili pakati pa 2.98 mm ndi 5.0 mm, ndipo mphamvu yoyesera yapamwamba kwambiri imatha kufika 50 A.
7. Chofufuzira cholumikizira batri
Kawirikawiri imagwiritsidwa ntchito kukonza mphamvu ya kulumikizana, yokhala ndi kukhazikika bwino komanso nthawi yayitali yogwira ntchito. Imagwiritsidwa ntchito poyendetsa magetsi pa gawo lolumikizirana la batri ya foni yam'manja, malo olumikizirana a SIM data card ndi gawo loyendetsera magetsi la mawonekedwe ojambulira omwe amagwiritsidwa ntchito kwambiri.
