Imashini ya PCB ni uburyo bwo gupima amashanyarazi, ikaba ari igice cy'ingenzi cy'ikoranabuhanga kandi ikaba n'igikoresho cyo guhuza no kuyobora ibice by'ikoranabuhanga. Imashini ya PCB ikoreshwa cyane mu gupima uburyo PCBA ihererekanya amakuru n'uburyo ihererekanya amakuru. Amakuru y'imikorere y'imashini ihererekanya amakuru ashobora gukoreshwa mu gusuzuma niba ibicuruzwa bifatanye n'ibisanzwe kandi niba amakuru y'imikorere ari asanzwe.
Muri rusange, probe ya PCB ifite ibisobanuro byinshi, ahanini bigizwe n'ibice bitatu: icya mbere, umuyoboro w'urushinge, ukozwe ahanini mu cyuma cy'umuringa kandi usizwe zahabu. Icya kabiri ni isoko, cyane cyane insinga y'icyuma cya piano n'icyuma cy'isoko gisizwe zahabu. Icya gatatu ni irangi rya nikeli, cyane cyane icyuma cy'ibikoresho (SK) cyangwa irangi rya zahabu. Ibice bitatu byavuzwe haruguru biteranyirizwa mu irangi. Byongeye kandi, hari agakoresho ko hanze, gashobora guhuzwa no gusudira.
Ubwoko bw'icyuma gipima PCB
1. Iperereza rya ICT
Intera ikunze gukoreshwa ni 1.27mm, 1.91MM, 2.54mm. Inzira ikunze gukoreshwa ni 100 series, 75 series, na 50 series. Zikoreshwa cyane cyane mu gupima circuit kuri interineti no gupima imikorere. Gupima ikoranabuhanga n'ibizamini bya FCT bikoreshwa kenshi mu gupima PCB zambaye ubusa.
2. Icupa ry'ibikoresho bifite impande ebyiri
Ikoreshwa mu gupima BGA. Irakomeye cyane kandi isaba ubuhanga buhanitse. Muri rusange, uduce twa IC twa terefone zigendanwa, uduce twa IC twa mudasobwa zigendanwa, mudasobwa za tableti na uduce twa IC tw’itumanaho birapimwa. Umurambararo w’urushinge ni hagati ya 0.25MM na 0.58MM.
3. Isuzuma ry'imashini
Imashini imwe y’amashanyarazi ifite imiyoboro ibiri y’amashanyarazi kugira ngo igenzure imikorere y’imiyoboro isanzwe ifunguye n’isanzwe ifunze.
4. Isuzuma ry'umuvuduko mwinshi
Ikoreshwa mu gupima ibimenyetso bifite umurongo wo hejuru, hamwe n'impeta yo kurinda, ishobora kugeragezwa muri 10GHz na 500MHz nta mpeta yo kurinda.
5. Icupa ry'urukiramende
Uburimbane muri rusange ntabwo buri hejuru, kuko ubushobozi bwayo bwo kwinjiramo buba bukomeye, kandi muri rusange ikoreshwa mu gupima PCBA byatunganyijwe na OSP.
6. Imashini ipima umuvuduko mwinshi w'amashanyarazi
Umurambararo w'icyuma gipima ni hagati ya mm 2.98 na mm 5.0, kandi umuvuduko ntarengwa w'amashanyarazi ushobora kugera kuri 50 A.
7. Imashini ipima batiri
Muri rusange ikoreshwa mu kunoza ingaruka zo gukoranaho, ifite umutekano mwiza kandi iramba. Ikoreshwa mu gutwara amashanyarazi ku gice cyo gukoranaho cya bateri ya telefoni igendanwa, umwanya wa SIM card hamwe n'igice cyo kuyobora cy'aho bateri ikoresha cyane.
