PCB probe ndiye njira yolumikizirana yoyezetsa magetsi, yomwe ndi gawo lofunikira lamagetsi komanso chonyamulira cholumikizira ndikuwongolera zida zamagetsi.PCB kafukufuku chimagwiritsidwa ntchito kuyesa kufala deta ndi kukhudzana conductive wa PCBA.Deta ya conductive transmission function ya probe ingagwiritsidwe ntchito kuweruza ngati chinthucho chikulumikizana bwino komanso ngati zomwe zachitikazo ndizabwinobwino.
Nthawi zambiri, kafukufuku wa PCB ali ndi mawonekedwe ambiri, makamaka opangidwa ndi magawo atatu: choyamba, chubu la singano, lomwe limapangidwa makamaka ndi aloyi yamkuwa ndikukutidwa ndi golide.Chachiwiri ndi kasupe, makamaka waya wachitsulo wa piyano ndipo zitsulo zamasika zimakutidwa ndi golide.Chachitatu ndi singano, makamaka chitsulo (SK) nickel plating kapena golide plating.Zigawo zitatu zapamwambazi zasonkhanitsidwa kukhala kafukufuku.Kuphatikiza apo, pali manja akunja, omwe amatha kulumikizidwa ndi kuwotcherera.
Mtundu wa kafukufuku wa PCB
1. Kafukufuku wa ICT
Malo omwe amagwiritsidwa ntchito kwambiri ndi 1.27mm, 1.91MM, 2.54mm.Mndandanda womwe umagwiritsidwa ntchito kwambiri ndi mndandanda wa 100, mndandanda wa 75, ndi mndandanda wa 50.Amagwiritsidwa ntchito makamaka pakuyesa madera a pa intaneti komanso kuyesa magwiridwe antchito.Kuyesa kwa ICT ndi kuyesa kwa FCT kumagwiritsidwa ntchito pafupipafupi kuyesa ma board opanda kanthu a PCB.
2. Kufufuza komaliza kawiri
Amagwiritsidwa ntchito poyesa BGA.Ndi yothina ndipo imafuna kupangidwa kwapamwamba.Nthawi zambiri, ma tchipisi a IC a foni yam'manja, tchipisi ta laputopu IC, makompyuta apakompyuta ndi tchipisi ta IC zolumikizana zimayesedwa.Kutalika kwa singano ndi pakati pa 0.25MM ndi 0.58MM.
3. Sinthani kafukufuku
Makina osinthira amodzi amakhala ndi mabwalo awiri apano kuti athe kuwongolera ntchito yotseguka komanso yotsekeka ya dera.
4. Kufufuza pafupipafupi
Imagwiritsidwa ntchito kuyesa ma siginecha apamwamba kwambiri, okhala ndi mphete yotchinga, imatha kuyesedwa mkati mwa 10GHz ndi 500MHz popanda mphete yotchinga.
5. Kufufuza kozungulira
The elasticity nthawi zambiri si mkulu, chifukwa malowedwe ake ndi amphamvu mwachibadwa, ndipo nthawi zambiri ntchito PCBA kuyezetsa amene kukonzedwa ndi OSP.
6. High panopa kafukufuku
Kutalika kwa probe kuli pakati pa 2.98 mm ndi 5.0 mm, ndipo kuyesa kwakukulu komweko kumatha kufika 50 A.
7. Battery kukhudzana kafukufuku
Nthawi zambiri amagwiritsidwa ntchito kukhathamiritsa kukhudzana kwenikweni, ndi bata wabwino ndi moyo wautali utumiki.Amagwiritsidwa ntchito poyendetsa magetsi pamalo olumikizirana ndi batire la foni yam'manja, kagawo kakang'ono ka SIM data card ndi gawo lothandizira la mawonekedwe omwe amagwiritsidwa ntchito kwambiri.
