Lingaliro la Flying Test, zabwino ndi zoyipa za PCB Flying Test

Kuyesa kwa Flying ndi njira imodzi yowonera ntchito yamagetsi ya PCB (mayeso otseguka komanso afupipafupi). Flying needle tester ndi njira yoyesera PCB m’malo opanga. Simagwiritsidwa ntchito pamabedi onse achikhalidwe a makina oyesera pa intaneti-Misomali), kuyesa kwa singano zowuluka kumagwiritsa ntchito ma probe anayi kapena asanu ndi atatu oyendetsedwa modziyimira pawokha kuti asunthire ku mayeso a mfundo ndi mfundo za zigawo zomwe zikuyesedwa. UUT (gawo loyesedwa) limatengedwa kupita kumalo oyeserera ndi lamba kapena njira ina yopatsira UUT
M’kati mwa makina. Pambuyo pake, kafukufuku wamakina oyesera amalumikizana ndi test pad ndikuyesa gawo limodzi lagawo lomwe likuyesedwa (UUT). Kufufuza koyeserera kumalumikizidwa ndi dalaivala kudzera munjira yochulukitsa (ma sign jenereta, magetsi, etc.) ndi masensa (digito multimeter, frequency counter, etc.) kuyesa zida za UUT. Pamene gawo likuyesedwa, zigawo zina pa UUT zimatetezedwa ndi magetsi kupyolera mu kafukufuku kuti zisawerengere Kusokoneza kwa Digital.

Kusiyana pakati pa kuyesa singano ndikuwuluka
◆ kuwuluka singano kuyezetsa makina ndi mmene zida ntchito capacitance njira. The test probe imayenda mofulumira mfundo ndi mfundo pa bolodi la dera kuti amalize mayeso.
◆ phunzirani bolodi lokhazikika poyamba ndikuwerenga mtengo wa capacitance pa intaneti iliyonse.
◆ kuyesa koyamba ndi njira capacitance, ndiyeno kutsimikizira molondola ndi kukana njira pamene capacitance kuyeza si m’gulu oyenerera.
◆ mizere inayi ingathe kuchitidwa.
◆ chifukwa cha kuthamanga kwapang’onopang’ono kuyezetsa, ndizoyenera kuyesa zitsanzo ndi batchi yaying’ono.

Ubwino ndi Zoyipa:
◆ singano yoyesera ndiyosavuta kuwonongeka
◆ wosakwiya mayeso liwiro
◆ kachulukidwe mayeso ndi mkulu, ndipo phula osachepera akhoza kufika 0.05mm kapena kuchepera
◆ palibe mtengo wokhazikika, kupulumutsa mtengo.
◆ kupirira magetsi sikungayesedwe, ndipo kuyesa kwapamwamba kwapamwamba kwapamwamba kumakhala ndi chiopsezo chachikulu.
