Ibisabwa bisanzwe kugirango ushireho uburebure bwa PCB irangi
Ubunini busanzwe bwo gutwikira ibicuruzwa byinshi byumuzunguruko ni microne 25 kugeza 127, naho ubunini bwibicuruzwa bimwe biri hasi.
Uburyo bwo gupima hamwe nigikoresho
Ikibaho cyumuzingi kigomba gukingirwa nibikoresho byoroshye cyane byo gutwikira kugirango hagabanuke ubushyuhe, kongera ibiro, nibindi bibazo bitandukanye.Hariho uburyo butatu bwingenzi bwo gupima ubunini bwimyenda ihuye.
Ubushyuhe bwa Firime Yuzuye - Ubunini bwa firime butose burashobora gupimwa neza na gipima gikwiye.Ibipimo bigizwe nurukurikirane rw'ibisobanuro, hamwe na buri menyo rifite uburebure buzwi.Shira igipimo kuri firime itose kugirango ufate igipimo cyoroshye cya firime, hanyuma ugwize icyo gipimo ukoresheje ijanisha ryibice bya coating kugirango ubare hafi yubushyuhe bwumye.
Micrometero - Ibipimo by'uburebure bwa Micrometero bifatwa ahantu henshi ku kibaho mbere na nyuma yo gutwikira.Ubunini bwakize bwakuweho bwakuwe mububyimbye butagabanijwemo kabiri hanyuma bigabanywa 2 kugirango bitange ubunini bwuruhande rumwe rwibibaho.Gutandukana bisanzwe mubipimo noneho bibarwa kugirango hamenyekane uburinganire.Ibipimo bya Micrometero nibyiza hamwe na coat zikomeye zidahinduka mukibazo.
Ultrasonic Thickness Gauge - Iyi gipimo ikoresha imiraba ya ultrasonic kugirango ipime uburebure bwa coating.Ifite akarusho kurenza eddy igezweho kuko idasaba icyuma cyinyuma.Umubyimba uterwa nigihe gitwara kugirango amajwi agende avuye muri transducer, anyuze hejuru, kandi agaragaze hejuru ya PCB.Ubu buryo ni bwiza kandi ntibwangiza PCB.
